How to add custom qty field to custom option of simple product magento

By default in magento there is no qty field of simple product for custom option. If you want to add qty as per your custom option you can add now using this post.

Suppose you have custom option 'Color: Red, Blue, White' of your simple product and you want to add different qty option for your color option you can do it now.

magento custom options quantity

1. go to app\design\adminhtml\default\default\template\catalog\product\edit\options\type\select.phtml

Find the below code:
'<th class="type-sku"><?php echo Mage::helper('catalog')->__('SKU') ?></th>'+

Now add following code just after above code.
'<th class="type-qty"><?php echo Mage::helper('catalog')->__('Qty') ?></th>'+

Find the below code:
'<td><input type="text" class="input-text" name="product[options][{{id}}][values][{{select_id}}][sku]" value="{{sku}}"></td>'+

Now add following code just after above code.
'<td><input type="text" class="input-text" name="product[options][{{id}}][values][{{select_id}}][qty]" value="{{qty}}"></td>'+

2. go to app\code\core\Mage\Adminhtml\Block\Catalog\Product\Edit\Tab\Options\Option.php

Find the below code:
$value['sku'] = $this->htmlEscape($option->getSku());

Now add following code just after above code.
$value['qty'] = $this->htmlEscape($option->getQty());

Find the below code:
'sku' => $this->htmlEscape($_value->getSku()),

Now add following code just after above code.
'qty' => $this->htmlEscape($_value->getQty()),

3. Add field in “catalog_product_option_type_value” table
`qty` int(11) unsigned NOT NULL DEFAULT '0' COMMENT 'Qty',

Now clear your cache and check in you magento admin. You can hit below if post is help full for you.

  1. Works fantastic.

    However might need a fix as csv files do not have the 'qty'. instead the values seems to go under '_custom_option_row_sku' in the csv file.

  2. Nice! But....
    is it combine the calculation?
    I mean lets say we have 4 t-shirts in stock and customer wants to buy two black
    both in XL size.
    The stock has the following combination: 2 red XL; 1 black XL; 1 black XXL;
    The above code suggests me that it's possible to the customer selecting two black
    XL t-shirts, however you have only one in stock, because the simple product qty is
    4, the size option qty for XL is 3, the color option qty for black is 2.

    In short, I don't see the connection in your code between the different options.
    Or do I miss something?

    1. For that you need to make some validation before adding item in the cart. You can validate this on your product details page.
