Dynamic Price Updater

[nyczhenry]

we need to get this specials thing working!

[bigsy85]

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

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/i...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.

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
