[bug reported] Technical error - Unabled to add product

[L. Brett Sinclair]

everything was fine and well with the beta 3 version that I had.
I decided to upgrade to the final 1.1 and now I can't add ANY products to the cart anymore.
I've search and this seems to have been fixed many time already...but this is back again.

Please tell what I need to do to fix it -

thank you - thank you - thank you

I also get this error with 1.1final.

In my case, this error will happen when I try to add product with many attributes but none of them are in stock.

Here is the situation:
Product A have 2 colors, black in stock, white out of stock ---> add to cart success
Fire Bug console response return:

http://localhost/prestashop/cart.php?_=1230139191382&add;&ajax;=true&qty=1&id_product=37&token=a942e3b5bcf94f4d054d286df7433eaa

Product B have 2 colors, none of them instock, ---> TECHNICAL ERROR: unable to add the product. Error thrown: [object XMLHttpRequest] Text status: parsererror
Fire Bug console response return:

http://localhost/prestashop/cart.php?_=1230139287961&add;&ajax;=true&qty=1&id_product=36&token=a942e3b5bcf94f4d054d286df7433eaa

This add to cart error will only happen in the product listing page. It will not appear when I try to add in it's own product page.
Fire Bug console response return:

http://localhost/prestashop/cart.php?_=1230139421446&add;&ajax;=true&qty=1&id_product=36&token=a942e3b5bcf94f4d054d286df7433eaa&ipa=143

Any body got idea on how to fix this? I will wait a few days before I report it as a bug.

[L. Brett Sinclair]

yes, I have the exact same case except that I do not manage any stock.
No trouble at all when adding the product from the listing page as well.
Now, when I turn off the AJAX feature, I have a blank page. So, I assume it has to do with a bug in the cart & AJAX...but don't know for sure either.

[chirameto]

I think the only logic that broken is the product attribute choosing when no attribute is selected. Everything else is fine and I am certain that stock management is not relate to this issue.

I try to turn of AJAX cart off and then add product to cart (from product listing page) in the following scenario:
product with multiple attributes, some of the attributes instock ---> it will take you directly to checkout page
product with multiple attributes, none of them instock ---> it will take you to product page and await for your choice of attribute

I don't get the blank page. and the customers shopping experience is not interrupted by error msg when AJAX is off. So this should be my temporary fix.

[L. Brett Sinclair]

ok - I agree, it has something to do with the attribute somehow.
Prestateam : Merry Christmas , get some champagne, foie gras and then maybe give us an answer when you get back?

bump
any help appreciated
thank you

[L. Brett Sinclair]

another bump before I report it to the bug ?

Hello,

Have you define your default transporter ???
I think that prestashop try to calculate the price with the default transporter when you add your product to the cart ...

Hope this help ...
Seb.

[L. Brett Sinclair]

good suggestion but I did -

[celyd]

I've the same issue.
Firebug show me a redirect (code 302) to the product page when product has combinations.
In this case, the response is no longer a JSON structure but a the html page.
That cause a parsing error.

[L. Brett Sinclair]

I have reported it to the bug tracker

[chirameto]

Ah.. I also submitted this bug. My bug number is 1143. Sorry I didn't let you guys (who share the same problems) know.

I have no knowledge of coding but I think the add to cart logic should be like this:
1) if there is no combination --> add item to cart (regardless of stock status)
2) if there are combinations --> take customer to product page and let them choose for their combination (don’t force to add something to cart or ajax cart regardless of stock status)
This way customers experience will be smooth and it should be easy for coding too.

Anyway, thanks for Presta Team for their effort. Since the bug was reported, let's sit back and wait for another release.

Hey guys!! I just checked the SVN version (clean installation with sample data). And the problem gone!!

I'll test with my own data again to make sure the problem has been cured.

[chirameto]

This problem has been fixed. I can confirm that the current SVN clean this problem. Thanks to presta team!!

If you are in a hurry and don't wanna use SVN, just check out only /classes/Product.php and replace your 1.1 final file.

[Lircky]

wow it;s fixed, but i don't understand how to fix it?!
SVN, what is it? where kan i find it?
And how exactly kan i fix this problem, hope that somebody can give me a clear anwser.

many THX

[ingenium]

I replaced Product.php with the version from subversion, and it corrects the problem, however now all pages are blank whenever a user is logged in. So this fix really isn't a fix.

Lircky, you can just go to http://svn.prestashop.com/trunk/ and navigate it via your browser instead of using subversion.

Edit: I've been able to fix the bug by disabling ajax, but I also had to unfortunately disable the security token or else I would get errors about hack attempts when adding an item to the cart.

[shutzu]

still now news about this?

[zippoutlet]

Already put a new post abt this matter...there are many stores working with the ajax cart...what is the solution for it?!?

Rgds,

[botc]

I also have this problem. If someone has a real fix, please post it in here

Thanks

I found that if you update your site map, your google product feed and basically refresh all your modules, it clears up.

Hi,

I have also this problem in version 1.2.4. Although I make the correct CHMOD in all directories, it doesn't works.
Blank page is still alive If I turn off ajax cart the problem is the same.
I'm gonna try in a different hosting.

Anything else ?

Best regards
