HELP! Buy now buttons all have same prod_id after continue shopping pressed

[knott]

Hi,

 

 

found a problem where if you add an item to your basket, then click continue shopping it returns to the list of products you were last viewing, fine....

 

but if you try and order one, it adds the same item you have already put in your cart. I've looked at the buttons and they all end up with the same products_id value.

 

any clues where I need to start looking?

 

Thank you.

UPDATE:-

 

This only occurs when the first item added to the cart has no attributes. Tested on 4 installs so far and found all have the same bug.

UPDATE:- Tested on a clean install and no problems so it must be one of the contribs installed...

 

ultimate seo urls

header tags

 

(can't see it being either of these 2 as loads of people use them & nothing reported)

 

discount coupons

 

 

the error seems to originate from

shopping_cart.php

 

as the continue shopping button contains the url http://mydomain.co.uk/catalogue/lights-c-1...products_id=205

 

 

(products_id=205 would be the id of the product that was last ordered & it makes all the buy now buttons in the category it returns to have that id)

Day 2 - still not managed to work out what's going on... please can someone help

Months later and I've still not fixed this properly....

 

It is something to do with...

 

<?php
   $back = sizeof($navigation->path)-2;
   if (isset($navigation->path[$back])) {
?>
               <td class="main"><?php echo '<a href="' . tep_href_link($navigation->path[$back]['page'], tep_array_to_string($navigation->path[$back]['get'], array('action')), $navigation->path[$back]['mode']) . '">' . tep_image_button('button_continue_shopping.gif', IMAGE_BUTTON_CONTINUE_SHOPPING) . '</a>'; ?></td>
<?php
   }
?>

 

so for now I found a sort of fix from another post...

 

<?php
   //$back = sizeof($navigation->path)-2;
   //if (isset($navigation->path[$back])) {
?>
                               <td class="main"><?php echo '<a href="' . tep_href_link(FILENAME_DEFAULT) . '">' . tep_image_button('button_continue.gif', IMAGE_BUTTON_CONTINUE) . '</a>'; ?></td>
<?php
   //}
?>

 

but that just goes back to the home page.

 

It would seem that the error is being caused in functions/navigation history

But I'm not really sure how.

 

Can anyone help?

It would seem that the error is being caused in functions/navigation history

Are you sure it is not a combination of this bug in product_listing.php and SEO url's?
