Duplicate quantity bug in IE6/IE7 + fix

gabrielk Total Posts: 83 Joined: 2007-11-30 Ignore user	Using IE6 and in early versions of IE7 (but not the latest), putting “1” quantity in the qty box on the product detail page then adding it to your cart will add 2 of the items. Leaving quantity blank and clicking “add to cart” only adds 1. Similarly, if an option is unavailable (e.g., size XL is unavailable and an error message reflecting this is shown) 1 item will still be added to the cart. /var/www/html/app/code/core/Mage/Checkout/Model/Cart.php Changing: `protected function _setProductQuoteQty(Mage_Catalog_Model_Product $product, $qty, $replace = false)` to `protected function _setProductQuoteQty(Mage_Catalog_Model_Product $product, $qty, $replace = true)` fixes this issue. It also changes the default functionality a bit, since it flags it to replace an existing item instead of adding another one of the same, obviously. However, it does get it wroking until the core code is updated with a more complete fix. This has been reported in the bug tracking: http://www.magentocommerce.com/bug-tracking/issue?issue=1237 Just thought I’d post it here too.

I unknowingly introduced this problem when I made the “add to cart” button a graphic. See the WRONG WAY and CORRECT WAY for codding this below. WRONG SYNTAX (causes 2 items to be added in IE) `<input type="image" src="add_to_cart.gif" onclick="productAddToCartForm.submit(); showhide('addingtocart');">` CORRECT SYNTAX `<a href="#" onclick="productAddToCartForm.submit();"><img src="add_to_cart.gif"></a>` Signature “Make everything as simple as possible, but not simpler.” - Albert Einstein

doctorlogos Total Posts: 178 Joined: 2008-05-06 Ignore user	I have a similar problem, but my version is 1.1.8 and I use firefox. When I put 1,2,3… items and add to Cart, then in the Cart, there are 2 or 3,4… items!!! It must be a Qty bug. I can´t believe it´s happening in this version. Please help!

Jeff Hope Total Posts: 3 Joined: 2008-09-02 Ignore user	I’m also having this problem, but ONLY with IE8 (beta). Leave 1 in box, Add to Cart, you get 2 (along with 2 green confirmation messages at the top). Change qty in box to 2, Add to Cart, you get 4 (with 4 green confirmation messages). This happens ONLY when adding to cart from the product detail pages, not the category pages where Add to Cart is also available - those work correctly. I’m running the latest Magento, 1.2.1. Funny thing is, this wasn’t happening before I upgraded. Not sure if it showed up this last upgrade, or the one before, but definitely wasn’t happening 2 upgrades ago. I haven’t changed the product detail template since then, so I have no idea what caused this. Site is http://www.countrycuredhams.com/ Thanks, Jeff

I had the duplicate quantity (and duplicate “Added to cart” message) in IE8 prior to forcing IE7 rendering. - Mark Signature . . . . . . . . . . . . . . . . . Mark J.

kcmr-z Total Posts: 3 Joined: 2009-06-01 Ignore user	The problem is the type="submit" attribute. I think this fires the form default action. Removing type="submit" works! <button onclick="productAddToCartForm.submit();"><?php echo $this->__('Add to Cart') ?></button>

Chickenfanny Total Posts: 15 Joined: 2009-02-12 Ignore user	This is a really irritating bug. I’m also seeing this, but only in IE 8. Are you guys editing the addtocart.phtml file to fix the problem? Here is the code from my addtocart.phtml: <?php $_product = $this->getProduct() ?> <?php if($_product->isSaleable()): ?> <fieldset class="add-to-cart-box"> <legend><?php echo $this->__('Add Items to Cart') ?></legend> <?php if(!$_product->isGrouped()): ?> <span class="qty-box"><label for="qty"><?php echo $this->__('Qty') ?>:</label> <input name="qty" type="text" class="input-text qty" id="qty" maxlength="12" value="<?php echo $this->getMinimalQty($_product) ?>" /></span> <?php endif; ?> <div class="button_left_pro"></div> <div class="left"><button class="form-button" onclick="productAddToCartForm.submit()"><span><?php echo $this->__('add to cart') ?></span></button></div> <div class="button_right_pro"></div> <div class="clear"></div> </fieldset> <?php endif; ?> I don’t see a type=submit in there anywhere, and cannot figure out how to fix this problem. Any help would be appreciated.

lorenthal Total Posts: 1 Joined: 2010-05-04 Ignore user	Just in case anybody else is experiencing the same IE8 bug, you just need to add type="button" to the “Add to cart” button. It seems that IE8 assumes that a button without the type property is actually a submit button and fires the submit event twice (one automatically and another because of the onclick event). So you will have: <button type="button" class="form-button" onclick="productAddToCartForm.submit()"><span><?php echo $this->__('Add to Cart') ?></span></button>

Michael Lambertz Total Posts: 12 Joined: 2009-12-21 Ignore user	Here an other working solution i found: Open the template yourdesign/template/catalog/product/view/addToCart.phtml and replace `<input ... onclick="productAddToCartForm.submit()" />` with `<input ... onclick="productAddToCartForm.submit(); return false;" />` Now it should work.
