Hi,

I did not found the woocommerce_template_functions.php in my WP + Woocommerce setup. Could you please elaborate where to paste the above mention code? I will be thankful to you. Thanks

I need this very urgently to add an custom text field on the single product page just above the add to cart where customers will add special instruction during add to cart. plz let me know how to use this code. Thanks !

In the current version of WooCommerce, the relevant file to update with this hack is "woocommerce/templates/single-product/add-to-cart/variable.php" (which you can copy under your own theme at "{your_theme}/woocommerce/single-product/add-to-cart/variable.php" in order to override it without the risk of a WooCommerce update blowing away your changes.

At least in the current version, though, this hack is only half the battle: you also have to extend https://github.com/woothemes/woocommerce/blob/master/assets/js/frontend/add-to-cart-variation.js to have it recognize that the input has been "fulfilled" so that it will show the "Add to Cart" button. The script is only looking at select elements right now, so this variation will never be fulfilled without updating the JavaScript.

Just compared this script with version 2.0.3 script and it looks different. Seems this script is not updated.

Hi, I'm searching a way to add 2 number input fields in WooC. , validate price based on both values from inputs, and save values on order pages, I've aadded fields to single-product, but i can't set price and save those numbers, can you,please, help me/look at my code?
