Dynamic Price Updater

Apologies if this has already been brought up, but is there any code changes available to make this work with qty discounts?

Cheers Chrome!

Hi OJM

It depends which version of the Updater you're using... V2 should handle quantity discounts out of the box while V1 wasn't capable of any discounts at all

I have installed the DPUv2 and it seems to work great! However I just initiated a sale price on all of my products and the sale price does not reflect in the update. See here

Maybe I jsut set up the options wrong... not quite sure..

Never mind... Just a quick setting... thx for the great mod

What setting did you have to change?

Hey Chrome, just wondering if you had gotten an update to the code yet?

I just installed this great mod and cannot get it to work with my sale price either.

My test site is here:
http://snow.byethost8.com/shop/index.php?main_page=product_info&cPath=7&products_id=1

When the page initially loads, the price shows:

Starting at: £15.00 £6.00
Save 60% off

The £15.00 has a strikethrough.

When price updater kicks in, the price changes to:
Starting at £15.00

I've found this post which I think explains how to rectify this:
http://www.zen-cart.com/forum/showthread.php?p=507151&highlight=sale#post507151

But I was wondering if there is a better or easier way than hacking the code?

Also, is there a way to stop the price updater kicking in when I change the quantity in the add to cart box?

Hi Chrome and all...

I've installed the price updater on a couple of shops without a problem.

But now i ran into one.

It somehow doesn't work on tabbed products when the attributes are in a tab.

Is there a workaround or a quick fix?

TIA, eentje

Thanks! :D.. I was looking for this capability. An old php shopping cart I used does that by default, which is lacking on Zen Cart.

I was looking on this forum to solve a different issue, but somehow I came across this thread, and when I read the original post, I knew I had to have it. No question about it.

I just unzipped the .zip file, then uploaded the file and two dir in about 3 seconds... went to my front page, hit Refresh, then I went to a product page, and sure enough, it updates as the attributes/options change.

This is something that should be a core part of Zen Cart.

eentje, I think the tabs are causing the same problem for us, I'll be troubleshooting this sometime this week. If I fix the problem Ill post it. :wink:

we need to get this specials thing working!
:flex:

Has anyone managed to get this working with other AJAX modules, such as the attributes change main image mod?

Hi Every one!!!

My problem is that, I do my all calculation on price, but now my new price will not to add as final price as I have no idea about final price variable , that I will assigned my final value to that that variable,
my link is:- http://team-kh.awpdc.com/~zadhnanr/bestlaminate.net/index.php?main_page=product_info&cPath=106&products_id=253

Please let me know if you have an idea about this situation.

But plz be urgent thanks.:clap:
Thanks
Zahid.

Hi all,

I've mentioned a problem I've had before but still not getting anywhere so I've decided to offer £50 sent via PayPay to whoever can fix it.

My problem is I use this mod with the 'attribute image replaces main image' mod. Both work together until the page stops loading then locks down, then only the price updates, and the image does not change?

I know its something to do with Ajax objects.
I think what needs to be done is put both Ajax requests from each mod into one. I have pasted the file including both mods which need combining to work.

I will really appreciate anyone's help, and I'm serious about the £50.

Hi Dan or anybody that can help ...

Simple question with a simple answer I hope ..

http://www.prestigeringcompany.com/index.php?main_page=product_info&cPath=1_2_3&products_id=56

The price i.e: Your Price: £110.00, appears twice on the page. I only want the second/lower price to appear. How would I go about this?

Many thanks in advance.

Steve

Hi all

I know I've been highly delinquent in my support of the Updater... For this I apologise; I've some serious employment issues and have hardly any time

Now, I know I've said this before but I am going to fix the Ajax issue (browsers permitting of course)

121: Your issue can be fixed by adjusting the line

var _secondPrice = 'cartAdd';

to

var _secondPrice = false;

HTH

Again, sorry everyone... I'll get back to work on this at my earliest opportunity

Dan

Can anyone suggest how to remove or hide the '(+$85.00)' from the attribute dropdown. With the dynamic updater, displaying this is kind of irrelevent as the price changed when the attribute is selected. It would make for a much cleaner display if this price increase did not display. Removing it from the modules/attributes.php causes problems with the updater though, so if anyone could make any suggestions, that would be appreciated.

Just remember to make a backup copy of your original file before making the modifications in case something goes wrong.

Hi All, Superb Addon, really a useful tool...

I found a small issue which I have worked around but thought I would post.

If you have the 'checkbox' attributes option, if you select two, it will not add the base price and only the(+ given_value) to the one already selected.

So if I'm selling size 1 for $20, size 2 is +$20 and size 3 is +40

If I were to sect options 2 AND 3 the price would be $80 and not $100 as it should be as on the 2nd option it misses the base price. I hope this makes sense...

Using radio buttons prevents this happening. No big deal, just thought I would bring it up.

Also - Where can I rename the 'Your Price' do I have to add a comment in order to do this as it seems to be auto generated in the jscript_ajax_update.php file???

One final thing, can I remove the brackets and (1) after Your Price as it will only ever be showing 1 on my site and its a bit pointless for my particular needs?

Thanks

Steve

Great mod. I have been using it with great success . Recently client notified me that the prices showing in the list view does not reflect the prices set by the attributes. Prices in the list view (basically the index page) are listing old prices prior to installation of 'Dynamic Price Updater ' .

How would I go about fixing that. My version of of Dynamic Price Updater was installed around August version v2.03

Thanks
