Dynamic Price Updater

Hi Dan,

thank you for your answers and time you have to spend.

Take care
Flo

I like this add on, but I have a small issue I can't seem to work out. I sell printing and want to set up my products with attribute pricing so my customers can calculate a price for any quantity instantly.

The way I have to price my products I need to us an attribute with a price per copy (ex. $0.01 for #20 white bond) and also use a one time charge (ex. $20.00) for setup costs of the print run. I put a test product on my site but it only shows the price per copy for Your Price: and doesn't add in the one time charge. It shows the total correctly in the shopping cart just not on the Your Price amount on the product page.

http://discountprintingservice.com/index.php?main_page=product_info&cPath=69&products_id=19812

Can your add on be configured so it will show the total price???

Thanks,

Hi

I don't know if this module will be of any use to anyone but I've been asked to include it a couple of times so thought I'd release it into the wild to see if anyone can make use of it... Here's what it does:

When you have a product with attributes that alter the price this module will update the price displayed on the page instantly... This gives customers an at-a-glance price total as opposed to having to work it out themselves

The updater should (in theory) work with any amount of attributes

There is a readme included in the ZIP but installation is literally to just upload the file... It overwrites nothing, has no database hooks and is completely autonomous... if it breaks just delete the file

Currently it only works with attributes that are SELECTs... If it works for people I will update it to handle the radio boxes and checkboxes

The file can be found at http://chrome.me.uk/PriceUpdater.zip

A working version can be seen at http://www.studio5.uk.com/index.php?main_page=product_info&cPath=2&products_id=3

Let me know if it does/doesn't work or if anyone wants anything added or changed

Dan

:clap:I think it is nice!

Thanks for the reply jstnice, but my question still isn't answered. In your attribute setting you have boxes to enter pricing per attribute:
Prices & Weights
Price---------Weight--------Order----------One Time
+.02-------------0-------------1---------------$25.00

When I test it it is only calculating the Price (+.02) and is not adding in the one time charge of $25.00. It does however add up in the shopping cart, it just doesn't show up on the product page for Your Price

For example, (base on the above example) if someone orders 1000 flyers it should multiply 1000 by the Price of +.02 (which would be $20.00) then add the one time charge of $25.00 for a total of $45.00.

On my test product it is only multiplying the price +0.02 by 1000 and displaying that number without adding in the one time charge of $25.00.

Can anyone tell me how to fix this???

:frusty:

Anyone got any ideas on this one???

Hi

Can anyone shed any light on this query!!

I have the Dynamic Price Updater installed on my website and:

I have been adding extra prices to certain attributes of my products recently and have now noticed the sum of the attributes (at product level) are different to the data that is inputted into Zen.

However, when you add the product to cart, the price reverts back to the correct price! You can also briefly see the correct price if you refresh the page at product level, but it will then change, and settle incorrectly.

I have gone through numerous settings on zen to track down where the error is coming from and it seems that the problem occurs when I change the individual products' 'Tax Class' from 'none' to 'Taxable Goods'. (which I have set at 17.5%)

If you have the time to take a quick look at the site:

http://www.prestigeringcompany.com/i...roducts_id=377

and suggest any solutions to this I would be most grateful.

I hope that makes sense.

cheers

Darrel

Sorry, to add:

I am currently using version 1.3.8

The price on the product page is always higher (1%) than it should be. If you refresh the page, you can see the CORRECT price very briefly and then it settles INCORRECTLY.

However, when you add the product to cart, the price reverts back to the CORRECT price that has been set for that particular product!!

I have viewed the 'pricing round up' thread issues, and it doesn't seem to be this as it is only the Dynamic Price Updater that gets the incorrect total.

Any suggestions would be very appreciated.

Thanks

Darrel

In my store I have a large amount of products that have no attributes, and when I use the DPUv2 the products that I have specials and no attributes get updated with the Special Price and when the product is Sold Out it shows as "Your Price: 0.00". The product that I'm testing has 3 attributes. The first one is "Add Canopy" and it is a check that adds $91.00. The second one is the finish options with radio buttons. They don't add any amount to the price, and the last attribute is purely a test called Other Option with a "Just Add Me" value and adds the amount of $35.00 to the price. Well, in that order, the canopy Updates the price with the $91.00, but the Just Add Me does not Update the price with its $35.00. If I shuffle the order of the attributes to Add Canopy (first), Just Add Me (second), and the Finish at the end, then it works and both Attributes get to Update the Price.

Using the original DPU, there are no problems with the rest of the products that don't have attributes. The test product with the attributes works exactly the same way that it does with DPUv2 but in IE it shows the Done (with errors) symbol on the lower left corner of the browser and when double clicking the error we get:

The error only shows in some IE in some computers, I have seen the IE in two different setups in different locations. I talk with my hosting and they had the same version of IE I have (version: 8.0.6001.18702 running Windows XP) and they didn't see the error. Firefox does not show the error. I setted up IE to not show errors, and it is still showing.:cry::frusty::Flush:

Hi all

Sorry for taking ages to reply... I've been away from my machine for some time and I'm just now getting caught up with everything

The tax problem I think I have an idea about now so I'm going to be looking into it as soon as I can

Fred, have you tried V2 of the Updater to see what that makes of your attributes? I know V2 has some issues currently but these seem to largely revolve around the tax class

Let me know and I will also check out your site

Cheers

Dan

Hi Dan, Check out the test product I set up with some attributes:

http://f i s h p e t l o v e . c o m /test

Just put the letters together and you will be there
I tried V2 also, but V2 had more problems. v1 gives the following error in the little triangle (Done but with errors) only shows in Internet explorer:

After looking at the error couple of times I figured out how to fix the problem, hopefully my fix is not going to kick me back :lamo: We will find out in the next couple of weeks, but here it goes:

	for (var i=0; objInp[i]; i++) {
		if (objInp[i].type == 'radio' || objInp[i].type == 'checkbox') { // make sure we're dealing with radio boxes
			db = 'Name - ' + objInp[i].name + ' : ID - ' + objInp[i].id;
	//Fred C fix 
	if(objInp[i].nextSibling != null){
	//end Fred C fix 
			matches = objInp[i].nextSibling.innerHTML.match(seeker);
			if (matches) {
				db += ' : Adjusted!';
				objInp[i].onclick = function () { updateR(this); }
				if (objInp[i].checked)	updateR(objInp[i]);
			}
		}
//Fred C fix 
}
//end Fred C fix
		regdb('Onload RAD/CH', db);
	}

Fred. :smile:

Ajeh:

The display is manage by the class in the template ... so I made the one at the top use a different class so the price did not change and put one at the bottom where the add to cart quantity is put in that had the class that gets changed ...

This way, the original price always shows on the page and the changing price of what the "actual" price will be based on quantity etc. would show right where the customer is working down by the attributes and add to cart quantity box ...

Hi Linda,

I failed to make DPU still showing the original price (didn't chnaged), instead of replacing it by just 'Your price: xxxx' because we have special price, so we can show how both original price and discount price.

I tried your method building a new class, above but couldn't get it to work, can you show me example of the file you modified?

I mean the file:
/classes/dynamic_price_updater.php

Thanks so much!

From what I remember on this one the:
zen_get_products_display_price

was in the :

and the update prices affect that ...

I just repeated the code without that and used a new class ...

I've installed this mod and it's working well. I've also installed this mod (http://www.zen-cart.com/forum/showthread.php?t=98641) to enable me to have a drop down menu on the product listing page rather than just the product info page. How would I go about having the price on that page dynamically update just like it does with the product info page?

To add a little bit more to my previous post...here is a link to my work-in-progress: https://www.mcqueeneycoins.com/index.php?main_page=index&cPath=1_2 showing the attribute drop-down mod in action.

On this page I want the prices to dynamically update when an attribute is selected, just as it does on the individual product's page. If anyone can shed some light on this for me I'm forever in your debt.

Thanks!

i think ```php
$this->_responseText['priceTotal'] .= $currencies->display_price($this->_shoppingCart->total, $product_check->fields['products_tax_class_id']);

```php
$this->_responseText['priceTotal'] .= $currencies->display_price($this->_shoppingCart->total, 0);
```because, if $product_check->fields['products_tax_class_id'] > 0 , this tax-value is added to priceTotal; the tax was already added

has anyone got an idea how to get this working with dual pricing- wholesale, and replace product images on attribute change? i know this has been asked before and i know you have a long list of stuff to do dan, but if you could point me in the right direction i might be able to figure it out, also i am willing to make a donation if you could get these 2 working with this mod.

i have a test set up here:

http://southcrystals.com/index.php?main_page=product_info&cPath=6&products_id=22

i had both of these mods working before DPUv2

this is zc 1.3.8a

and if you need ftp in order to help me out just let me know.

also how do i remove the product quantity in parenthesis?

thank you so much for all of your time and energy into this dan, i have read through almost everythread of this topic and used a few of your fixes aready to get it working so far, but i do really need these other two working as well, as they took me forever to get working too.

ok, so i am assuming that the file that mainly needs to be edited is

includes/classes/dynamic_price_updater.php (to get the dual price - wholesale price mod to work)

here is what i have changed it to

i know i am not doing this right, i see that i have inserted the wholesale code into a function, and im not good with this stuff, but i will keep playing around.

i have figured why (i think) i cannot get this to work.

it is calculating from priceTotal which is from the price update mod only, so it will not show any other prices. i am unsure how to merge these....

i will leave it alone for now, but ANY ideas are welcome, thank you!

Hi!,

I install this tool and works ok, but then the "attribute replace main product image" don´t work.

I want that when customer select an attribute, for example a color that is moore expensive, the main product image and price change to the new image and price.

Separately the DPU and "attribute replace main product image" works ok, but not together.

Anyone knows how can I obtain this effect or why this two modules don´t work together?

Thank you very much.
