Dynamic Price Updater

Hi,

thanks to Design75 for taking up with DPU.
I'm still looking for a solution to this problem:
[26-Mar-2014 05:07:01] PHP Warning: reset() expects parameter 1 to be array, null given in /.../includes/classes/dynamic_price_updater.php on line 175
[26-Mar-2014 05:07:01] PHP Warning: Variable passed to each() is not an array or object in /.../includes/classes/dynamic_price_updater.php on line 176
Actually It showes up only rarely, but still i'm unable to get why.
Tryed a couple of thing but nothing fixed the error and cause it seems just to generate the error log (no other problem found) I stepped over, but every time I see the error log it itches :blink:
If anyone have suggestion you are welcome :smile:

The site is http://www.laviadellincenso.it

Zencart 1.51
DPU 3.01

Any updates on the
[20-Apr-2014 09:58:00 UTC] PHP Warning: reset() expects parameter 1 to be array, null given in /var/xxxxx/includes/classes/dynamic_price_updater.php on line 175
[20-Apr-2014 09:58:00 UTC] PHP Warning: Variable passed to each() is not an array or object in /var/xxxxx/httpdocs/includes/classes/dynamic_price_updater.php on line 176

??
See it all the time in my error logs.

Hi all

I do apologise for my time away from supporting the Updater... I've been called back in to solve this issue with the error message logging... I hadn't been paying attention to the thread (work has taken the place where I once had a life)

As soon as I have a solution I will update the thread

Cheers

Dan

Hi all

I'm having some issues building a test environment, but I think I can fix this without it... Could I ask for volunteers?

Here's one

Hi Design75

Sorry the time taken to respond; I decided to rewrite the fix... I'll also resubmit for verification after testing

File is attached

Thanks!

Dan

Hi all

I've added a few changes to the Updater's class file... Here are the changes:

- Changed the way the sidebox switch works (more a cosmetic/elegance alteration than anything, really)

- Fixed the errors caused by the reset() and each() calls (I hope)... This error was my making

- Altered the error logging method... Here I owe Design75 an apology as I incorrectly thought it was an example of bad design, but rather it's (I think) throwError() might be a magic function that's called in the event of any error in the class, rather than explicitly... It took me a while to figure out quite why the files were being created... After I figured this out I realised Design75's intention to alert the user to any error that had happened... I've added a drink icon as a peace offering to Design75 and my unreserved apologies... I'm sorry I reacted without fully checking and considering the situation... The logger now creates a single file in the logs folder and appends errors there

All that said, I've attached a replacement file for anyone that's kind enough to test it for me... The file only contains the affected class in its folder structure... Here's what needs to be tested:

- The _runDeep var that switches the sidebox on and off... This var is set in the class constructor

- The noted errors about reset() and each() to make sure they're squashed

- The new error logger... Easiest test is to manually call the logger directly, e.g. $this->throwError("Test error logger"); in the constructor

- The _runSilent flag that controls whether errors should be logged... Check that the log file is being created and it's in the correct place... Run the error test several times to ensure content is appending and not overwriting (this shouldn't be a problem)... Var is set in the constructor

All changes are commented but if anyone has any questions, please feel free to post here

Many thanks to everyone that tests and, again, my sincere apologies to Design75 (I really don't know where my head was)

Cheers

Dan

:laugh: No apologies needed. We al have our bad day, and you thought you were doing the right thing. I really appreciate you are back here and trying to make this module better. :hug:

Hi

Thank you Design75, I very much appreciate that :smile: :hug:

I've decided it's time to move the Updater forward... Firstly, an installer: To save mistakes and make it easier for newer users I plan to make an installer that sets the admin folder and template folder names and puts all the files in the correct place

Secondly, rather than digging about in the files for switches and changes, it's time for an admin page... Digging about in code files isn't for the faint of heart

So here are a few questions in anyone fancies a ponder:

- Should this version be a replacement (v4.0) or should it be a parallel version (offered at the same time as v3, which remains supported)? Is there a case for someone preferring or requiring the v3 over the installer version with admin panel?

- Apart from the standard switches (sidebox switch, error switch, quantity display switch etc.), what else could be added to help tweak and control the Updater? This can be anything from display to adding features that have never existed on the public side... So any feature request really

Thanks for all the support

Dan

The latest version already contain an auto installer. It is not the best, since this was one of my first modules to upgrade ;) At the same time I also moved most, if not all settings to the admin.

One feature I would like, and which I have not had the time to start on, is when there is a minimal amount of products that needs to be added to a cart, the updater does not update when opening the product_info page.

Hi

I now have my test area set up, so I can see that you have added the admin bit... Great! I hope you don't mind that I build upon that code

The idea I had for the installer is purely to rename the folders automatically after upload... In tandem with your installer, that would be ideal

I'm just now doing some testing, then I'm going straight onto the upgrades... I have a few ideas myself, so I'll start building on them

Cheers!

Be my guest, to modify the code at your will :smile:. I am still available if you need a tester.

Hi Dan,

good to see You back :smile:

1. This version should be a replacement (v4.0) not a parallel one. Personally io dont like when there are "parallel" version, it is always confusing.

2. The thing that i always loved of DPU is it's simplicity, works well because it's "simple". I would not add too many functions or options, the basic options are already enough.

Hi izar74

On point #1 I'm in complete agreement; I just wanted to make sure (I will support older versions (within reason) of course)

With point 2 I was thinking of splitting the features into Essential and Advanced: Essential would be what's already there (with the possible exception of some new switches)... Advanced would have things like control over classnames, other code-level display tweaks

Thanks again to Design75! Did you try the single file replacement I last posted? Can you spot anything weird in there?

I'm working on the Updater now and may even (FINALLY) have a proper crack at multiple updates (I recall this request being almost as old as the thread)

Thanks to all for the support!

Dan

Hi, Ive just installed this mod and I get a popup saying "Internal Server Error"
I used version 3.0, my store is 1.39h. The details for 3.0 say its for 1.5x, does it also work with 1.39h?

I always get confused on this point as so many mods still work even when it says 1.5x in the Zencart versions.

If it works with 1.39h, what might my problem be? I search this thread for "Internal Server Error" and only found one mention of the problem but no fix.

Hi

This version certainly should work for 1.3.9h, but I can't offer a guarantee

As for the Infernal Server Error, you will have to have a look at your apache_error.log to figure out what exactly is happening... If you can, provide the error messages I will try to help you get to the bottom of this

Cheers

Dan

Hi, that file is pretty big, 83 meg. There is another error on that site which is in relation to something else so Ive had no luck really locating anything in the file. What should I search for perhaps?

Hi Chargin

Here's what I'd do:

- Put the site in maintenance mode
- Make a note of the time
- Visit a page that causes the error
- Immediately copy the last few lines of the error log
- Post them here, remembering to obfuscate anything security-related

I don't know what kind of access you have but PHP can store its own error log. Do you have access to whether the logging feature is access and that file? If you do then make sure that PHP error logging is switched on before carrying out the above steps (probably should work on the order of my instructions)

If you have any questions or results please post them here

Cheers

Dan

Hi All

I have had the dynamic price updater on my site for ages all fine, then I move the site to a new server and it no longer works. I have updated it to a newer version still nothing. It show the graphic when you change qty etc but the price stays the same, the amount changes to the correct one when you add to basket. The site www.countbanners.co.uk. Im at a loss now as to why.

Thanks in advance
Drew

ZC 1.5.1 With the DPU 3.0.2

Copied files to the correct directory- tried to open my ZC admin- got a HTTP500 error. I went in and removed Admin>Includes>auto_loaders>config.dpu.php and the ZC Admin will open with no error. Now, of course the DPU didn't load, but I think I've narrowed down the offending file.

Can anyone assist. Any ideas why I can't get the DPU to load into ZCADMIN without an error?

Thanks. www.infidelbodyarmor.com

Hi All

Anderson, I wasn't able to get that URL to load; are you sure it's correct?

Infidel, there is a post a little further up the page about 500 errors. Could you try the advice from there and see what you find? Let me know

Cheers

Dan

Hi Dan my bad its www.countybanners.co.UK thanks Drew

Hi

I did think countbanners,com was a bit, well, niche

I'll take a look now

Dan

OK a strange one, the dynamic price updater works on mobile phones but not tablets or desktop PCs..

Does anybody know where is the updateR function in Dynamic Price Updater for 1.5?

Has it been disappear?

I'm trying to update a 1.3.8a to 1.5 zencart, and this addon is highly used.

As far as I know it has never been a part of DPU

Thank you!

Greetings and thanks very much for this addon.

I have searched this thread completely and cannot find an answer as to whether this modification works on the product listing screen. On my installation of Zen-Cart, it only works when viewing a single product. The question has been asked several times but there has not been an answer given, one way or the other other.

So, does this modification work on the product listing page or am I simply missing something to make it work?

Thanks to anyone who can shed a little light on this for me.

No, it does not work on the product listing page, and it never will, because there are no attributes to select from in the product listing.

---

Oh, Ok. I guess I have been running the Attributes On Products Listings 2.0 so long, I'd forgotten that it was a plug-in.

That being the case, I wonder how difficult it would be to add dynamic price update functionality to work in conjunction with this plug-in. I'm using ZC 1.5.1.

It would be nice to be able to select the attribute and have the price update here, as well.

Ah I see, I wiil put it on my to do list, but I can not promise anything. It is a long list :laugh:

Many thanks for your help Erik. :laugh:

I don't know about the second part, but I had the total showing twice on one of the sites where I installed the mod. Solved it by adding this to the stylesheet:

#productPricesSecond {display: none;}

If anyone is using any Numinix products or any other modules that add extra columns to the configuration table, you will experience an error when installing this module!

The log file will show "PHP Fatal error." To fix this problem, you must supply the columns you intend to modify when performing an INSERT (which is good practice IMHO).

For example line 49 of init_dpu_config.php should read:

Code:

---

$sql = "INSERT INTO ".DB_PREFIX."configuration (configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) VALUES (NULL, 'Dynamic Price Updater Status', 'DPU_STATUS', 'false', 'Enable Dynamic Price Updater?', '".$dpu_configuration_id."', 10, NOW(), NOW(), NULL, 'zen_cfg_select_option(array(''true'', ''false''),')";

---

That should be replicated for all INSERT commands into the configuration table (or any table for that matter).

You are absolutely right. And it was already scheduled for a next release.

Don't thank. Me for the plugin :smile: it was Chrome who made it, I merely updated it.
I am thinking about rewriting it to use Ajax and jQuery, but those are future plans.

Great plugin!!

But I have a question; I would like to have a different fontsize for the komma and the last two digits of the price, is there a way to do this?

Recommend (if not already considered) also that the DB_PREFIX."configuration be changed to simply TABLE_CONFIGURATION as in the below and the configuration_id be removed so that it is system independent and because it is auto_generated (some systems don't like NULL and require 0, but they both end up doing the same thing, assigning the next id.. Update is shown below, another recommendation is a matter of "taste", but one may assume that the addition of a key is not the same as a modification of it (also see the example sql for populating the database with the demo product that the last_modified field is generally not set to a date), so the last_modified field probably could be left off the insert. That has not been incorporated below):

Code:

---

$sql = "INSERT INTO ".TABLE_CONFIGURATION." (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) VALUES ('Dynamic Price Updater Status', 'DPU_STATUS', 'false', 'Enable Dynamic Price Updater?', '".$dpu_configuration_id."', 10, NOW(), NOW(), NULL, 'zen_cfg_select_option(array(''true'', ''false''),')";

---

THanks, this is somethying i already had changed in the test version. Theoretically it is possible someone changes the name of the configuration table.

It can be done, but not very easy. You will have to split the price in two parts, and place a <span> around the comma with a class. This could be done using jQuery.

It can't be done with php? I have no knowledge of jQuery..
I thought if someone could show me where I can find the 'final output' of this plugin I might find a way.. :blush:

Can you tell me where I can find the price? Or maybe refer me to a post in which it is explained?

I assume that from there on I will figure out how to change this :lookaroun

Thx in advance

I'll look it up tommorow, and let you know

When I change family size price changes. So beautiful. But I also want to change to the extra options. Because family size of extra options are 2 euro. Is it possible?

Attachment 14882

Not sure, but looks like a checkbox is used... Further not sure if the plugin works/recognizes checkboxes... May want to switch to a radio button or dropdown with an additional option of both items and an individual price for that mixture. That's also assuming that the plugin works with multiple attributes.

But when I change family size same time change to extra options attribute.

---

I thought I should share my answer to my own question :D
Eventually I figured it out.

In the file /includes/classes/dynamic_price_updater.php at line 83,
after this:

Code:

---

$this->responseText['priceTotal'] .= number_format($this->shoppingCart->total, 2);
    } else {
      $this->responseText['priceTotal'] .= $currencies->display_price($this->shoppingCart->total, 0);

---

and before this:

Code:

---

    $this->responseText['weight'] = (string)$this->shoppingCart->weight;

---

I have added this:

Code:

---

    $nweprijs = $this->responseText['priceTotal']  ;
    $this->responseText['priceTotal'] =  '<span class="prijs">' . substr($nweprijs, 0, -3) . '</span>' . '<span class="komma">' . substr($nweprijs, -3) . '</span>';

---

This will give you extra classes for the price, so it is possible to have something like this: 19,95

It is probably not the best way to do this, but it works :P

Is it ok to use Dynamic Price Updater on ZenCart 1.5.3? On the plugin page, it just says 1.5.0 and 1.5.1

Yes it is, I have it working on 1.5.3 and 1.5.4 sites

Hi

I need to change the position of the DPU line: At the moment it shows underneath our add to cart button. I really need to be able to move it above here as we have quite a lot of options.

I have gone through product-info-display.php, but can see that it is written by JQuery not PHP.

Please could anyone advise?

Also I am getting a conflict error thats stopping another function working on in MSIE and iPad (Safari)

I have used Firebug and the Console is throwing the error:

Quote:

---

TypeError: objSB.appendChild is not a function

---

I am using the latest version of DPU as the site is only 4 months old.

Please could anyone advise? Is this a known error?

Actually this one I did resolve myself: Under configuration My Store > Dynamic Price Updater, Under Where to display the second price I changed from the location from cartAdd to productAttributes.

And this appears after the declared element :blush:

I assume I am the only one getting a conflict error. :dontgetit

No you're not :cool:, but I think most people don't know.

I did some changes to get rid of the error, I'll have to look them up. I will come back later to tell you what I did.

Aww thanks design75. I remember lst year on setting this up how helpful you are. :cool:

Hello

Do you have a solution for calculating with Discount in Percent ?

Thanks

I think this is the code you were looking for, in the file "includes/modules/pages/product_info/jscript_dynamic_price_updater.php"

form line 309 remove the following lines. These are I believe obsolete.

PHP Code:

---

<?php
  $show_dynamic_price_updater_sidebox = true;

    if ($show_dynamic_price_updater_sidebox == true)
    {
?>
    createSB();
<?php
    }
?>

---

And maybe the whole function init() can be removed, but I haven't tested that yet

I thought it had, but it doesn't seem to have made any difference.

I don't really use the sidebox area so thats probably why removing those lines didn't work for me.

I'll give you all the info I have on my test server: I am using the module http://vinosdefrutastropicales.com/i...products_id=46 which bought the script conflict to light for me.

Using Firebug, I can pinpoint that the error is on line 382 of index.php

Firebug is flagging

I am aware that I have 3 additional modules in place. That unfortunately in beyond my control.

I hope at least some of this helps. As I said, I appreciate any help. :)

Hi, did the above help at all?

Sorry, but I have not had the time to look at it. Personally I never use the side box, so I will have to do some research before i can help. With some luck I will have some more time later this week

Ok Thanks Erik. I do appreciate any help. :smile:

Hi Erik

Sorry to be a PITA. Have you had any breakthroughs? :smile:

Having a bit of an issue. I had this working just fine in V1.5.1 and have since updated to 1.5.4. The template used (Abbington_Mega) is the same as when I was using 1.5.1. For some reason, the sidebox just displays the spinning loader image and the main price display does not update. I have it showing up in the admin window to make changes to the settings, however, I am not sure what settings if any are needed. In V1.5.1, the main price listing would change when an attribute was selected which added to the price, but now, nothing seems to happen. I did run the dataase through the upgrade process from 1.5.1 to 1.5.4, so I am not sure if that caused any issues. Thanks in advance for the guidance!

Quick Edit, I discovered that this mod works with the default classic template, but for some reason the Abbington_Mega template is not allowing it to work. I will check with the creator of that template and see what input they have.

I have checked with the creator of the template and they said that any verified plugin should work if properly merged. What I am not understanding is: since there are no files modified and the updater is simply dropped into the respective folders, what could be wrong with it not updating properly with this template. I reverified that all the files are in their proper folders as well as double checked it working just fine with the classic template on my server. More than a bit frustrating since the creator of the abbington_mega template seems like they are placing responsibility on your plugin rather than a possible conflict of some sort.

The only reason I can think of why it should not work, is that you didn't copy all the file to your abbington_mega template folders. I have this module running on multiple zen carts, without a problem.
Please recheck your files.

I've had this module working for a long time. I just noticed it was now not working.
In the console this error is shown:
"XML or text declaration not at start of entity" which is caused by anything being output before the <?xml version="1.0" encoding="utf-8"?> at the start of the file.
I find in the file that there is one whitespace character before the <?xml...

If your call this file directly:
http://YOURSHOP/dpu_ajax.php
you will/will not see this error flagged up in FFox,Chrome, Opera but not IE.

Removing the XML declaration entirely from the includes/classes/dynamic_price_updater.php allows the updater to work again but I would like to know why this has suddenly become an issue and how to fix it properly.

PHP Code:

---

function dumpOutput() {
    // output the header for XML
    header('Content-Type: text/xml');// set the XML file DOCTYPE
    echo '<?xml version="1.0" encoding="utf-8"?>'."\n";
    // set the responseType

---

to

PHP Code:

---

function dumpOutput() {
    // output the header for XML
    header('Content-Type: text/xml');// set the XML file DOCTYPE
    // set the responseType 


---

If the DPU admin option for a second price display is left blank/not used, it causes this javascript error.
This is due to the code check:

Quote:

---

if (_secondPrice !== false) updSP();

---

which will be true if the field is empty and so will try to find the element that has no name set.

I changed it to this to stop the error:

Quote:

---

if (_secondPrice !== '') updSP();

---

Hi, the plugin is working great. I was just wondering if it's possible to set a dropdown box to change the price of the product depending on which item is selected in a radio button? So that if the user selects the first option in the radio and an amount of 3 in the dropdown box the price will increase by x amount, but if the user chooses the second option in the radio and an amount of 3 in the dropdown the price will increase by z amount. And so on.

A colleague has found a bug with the plugin. When you go to the checkout, then click on the item in the shopping cart, it goes back to the page for the product, however the price is listed as the 'starting at' price, even though there are attributes still selected.

Okay, I get the same result... Now for the solution. Right now I am lacking the time to work on this, but it is on my to do list.

Hi Design75

Going all the way back to my post https://www.zen-cart.com/showthread....33#post1279633 the conflict error has reared its head again.

It wasn't a problem before, but now Google have discredited our main product due to this issue, it now is a problem.

Please could you help/advise?

Many many thanks,

I have two screenshots of both the error and the offending line (attached)

Attachment 15641
Attachment 15642

Althought these aren't as clear on the image the error message in Google Chrome > Developer Tools is :

Code:

---

firstGroup optionID: 3
Uncaught NotFoundError: Failed to

execute 'removeChild' on 'Node': The node to be removed

is not a child of this node.

---

And the offending code is (bold and in red)

Code:

---

temp = temp.substr(0, temp.length - 1)
  this.getData('post', 'handlePrice()', temp);
}

objXHR.prototype.handlePrice = function () {
  var thePrice = document.getElementById('productPrices');
  thePrice.removeChild(loadImg);
 
  // use the spans to see if there is a discount occuring up in this here house
  var test = thePrice.getElementsByTagName('span');
  var psp = false;

This module works great! Thank you for contributing it, it's really awesome, and I wish zencart came with this functionality already. The only thing is I can't get it to work with my add-this buttons. When turned on, my add this buttons won't show. I am guessing this is obviously a javascript problem, so I am figuring I need to edit these two files included with the module:

includes/modules/pages/product_info/jscript_dynamic_price_updater.php
includes/modules/pages/product_music_info/jscript_dynamic_price_updater.php

Not sure what to do though.

Hello,

works great on my client side (even if I'm using an old version on 1.5.4 upgrade planned).
I was wondering, would it be difficult to make it run on the admin side, inside Edit Orders ?

I'm using Edit orders and when I'm changing an order, of course nothing changes.

Thanks for your help

Regards

Hubert

To be honest, I have no idea. This would require a complete rewrite of the code.

Nice mod question has anyone got it to work on the product_listing.php page? It works fine on the info page but I use a module that shows attributes on the product listing page and need this to work on it as well.

This is the other module I'm trying to get it to work with:

For DPU to work on the product listing you would have to rewrite the whole DPU mod

Hello there,

Does anybody have success making this work on 1.5.5? Thanks in advance

I got around those install errors, adding a ", null" in some lines then adding "sometext" in others in the code between 50 and 60 at init_dpu_config, it seems one column to add to the database was missing in those lines.
But now I cant see how to make the plugin to work, I can see the options on the admin side, "Where to display the price", when I use "productsGeneral" which is the <h2> that contains the price text tag, I choose between the attributes I see the loading GIF but the main price doesnt change, if I leave it blank or try to set another ID(of course I create a input field or a simple text spam field with an ID first), nothing happens, even the loading GIF is not there.

Im using Zencart 1.5.5 with responsive Sheffield blue, I had tried the default template too, it doesnt work.

I have been using zen cart for ten years, this kind of stuff should be there by default by now, like when people select another quantity of the same product, price should be updating without the need of pressing "add to cart" button.

This is how my config Admin looks like.

This is an url with a product with attributes, DPU is on.

Thanks in advance.

See: https://www.zen-cart.com/showthread....33#post1269333

This isn't a ZC 1.5.5 specific issue. It is a result of installing a modification that changed the configuration table and the fact that this mod hasn't incorporated the code change referenced in the above link or similar.

If I do as suggested in your post I receive this error. If I add the word Value before (null,...) I receive the same error I was receiving, about columns not matching as requested...

OK JUST IGNORE THIS, I forgot to delete the first "NUll" of every line.

Sadly, its not still working in the frontend...

As already pointed out there was a discrepancy in the sql, but all-in-all, the above is not at all what was suggested to be performed. The below is an example of how the line(s) should be written. Further based on the presentation of the configuration menu as compared to what is expected, som "unknown" values were placed in unknown location within the sql. This could cause unknown issues:

Code:

---

$sql = "INSERT INTO ".TABLE_CONFIGURATION." (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) VALUES ('Dynamic Price Updater Status', 'DPU_STATUS', 'false', 'Enable Dynamic Price Updater?', '".$dpu_configuration_id."', 10, NOW(), NOW(), NULL, 'zen_cfg_select_option(array(''true'', ''false''),')";

---

Ok. Checking out my database I found after the 'trim(') code present in line 54, the rest of the lines werent be added to the database, and again in line 60 this code 'zen_cfg_select_option(array(''true'', ''false''),') wasnt allowing the last line being added to de DB, I change both to null, then going PHPMYADMIN and adding this 'zen_cfg_select_option(array(''true'', ''false''),') manually.
It seems everything is fine now with the DB, all the lines are there, and now I can see all the radio buttons on the true/false options in the backend, something It wasnt ther before. BUT, frontend is still not working.
I tought this plugin needed the sidebox to be activated, so I change the template to the classic one and turn on the sidebox, the sidebox doesnt show anything but the loading gif logo.

Checking the console error in Firebug and Chrome I receive this.

TypeError: this._responseXML is null
var type = this._responseXML.getElementsByTagName('responseType')[0].childNodes[0].nodeValue;

Checking the DOM, well it confirms that the value of this._responseXML is indeed NULL.

I get lost here, but I need this to work, was basically the most important thing my client wants in his website.

Hi

I have been using DPU for about 2 years.

I have just set up a new template and although the system is working fine on my local testing environment, I keep getting a status returned window pop up on my live site

Attachment 16391

And I cannot work out why. Please help :shocking:

Actually panic over.

I located /public_html/includes/modules/pages/product_info/jscript_dynamic_price_updater.php and at around line 36

Code:

---

var theURL = '<?php echo DIR_WS_CATALOG; ?>dpu_ajax.php';

---

For some ungodly reason had a '/' before it (that might be a setting down added to get this working on my local testing environment).

Anyway its removed and is now working. Happy days :cool:

Cant someone confirm for real, that this is working for 1.55? Please dont try to guess, if you know this is really working with 1.55 or 1.55a please link to the store where the plugin is working on, so I would try to make a clean installation to make this work. Im really tired, I have wasted one month trying to make this work...

I can confirm that results can be obtained from using much of the software offered in the plugin while using ZC 1.5.5/1.5.5.a, but I was provided a site that had already tried to install it and had some difficulty in operation. Which means I did not start with a fresh download of the plugin, but instead resolving the issues before me.

Anyways, after correcting html validation issues (apparently extreme) the plugin does what it should, though I'm finding that I have an additional onchange event to be executes, but it gets overwritten, etc... so have to javascript my way to what I want/need. :P but it does work.

Does the latest version of this plugin work with 1.39h? or should I install an older version?

Ultimately instead of applying this to an older version of ZC, should be considering upgrading your ZC. ZC 1.5.5 will still operate in an environment with PHP 5.2.x installed, but more PHP older than 5.4 is no longer considered supported by the PHP community and is less secure than more recent versions.

I will try a fresh install, then I will add this plugin first, testing, then adding the rest of the plugins, to see if there is any other plugin that is breaking it. Thanks.
