Internet Explorer Adds Twice the Quantity to Cart

Written by Gordon

Topics: Magento

We all like to style our Magento add to cart button as an image button. The problem is that IE 8 (Internet Explorer 8) will add the product twice and cause the quantity of that product in the cart to double up. There is an easy fix to this problem.


<input type="image" src="<?php echo $this->getSkinUrl('add-to-basket.png') ?>"
name="image-button" onclick="productAddToCartForm.submit(); return false;" />

Notice the return false; that I’ve added after the productAddToCartForm.submit().

This will fix the problem of IE submitting the add to cart button twice.

Update (Thanks Barcaro) :
File where edit is to be made…
(change /default/default/ to your custom template path).

    You have to modify the list.phtml accordingly, for the case if someone adds to the chart direct from the listing.


    <button type="button" title="__(‘Add to Cart’) ?>” class=”button btn-cart” onclick=”setLocation(‘getAddToCartUrl($_product) ?>’); return false;”>__(‘Add to Cart’) ?>

    Notice the “return false” which has been added. Around line 57.
