WP Theme / WooCommerce / JS Issue - Cannot read property of undefined.

Here's the info that I know.. not a JS expert so bear with me.

  • Running the theme Reaction WP by MakeDesign, it's based on SuperSkeleton.
  • Integrating WooCommerce 2.0.3.
  • The store worked with WooCommerce 1.6 and we were able to process orders. Since upgrading to 2.0.3, something changed and there is an issue adding variable products to the cart.
  • The site is running JQuery 1.8.3.
  • If I switch to the TwentyEleven theme, the issue resolves itself.

Live store site: http://www.connectedinmotion.ca/shop/portage-tee/

If you jump into console, you will see the error message:

Uncaught TypeError: Cannot read property '7587' of undefined

Where 7587 is the WP PostID.

The error is obviously within add-to-cart-variation.min.js and passing something back to the page, but I'm not sure what to add.

It would be easier to troubleshoot if you could change the page to include the non-minified version of the JS (which appears to be at http://www.connectedinmotion.ca/wp-content/plugins/woocommerce/assets/js/frontend/add-to-cart-variation.js).

Sorry about that. I overwrote .min with the contents of the non-minified. Faster than finding where the call to .min was coming from. It appears to be on line 130.

Just confirming - If you change themes, this works flawlessly? That's very weird because the issue seems to occur with the woocommerce plugin which should work the same regardless of the theme, right?

It looks like it has something to do with the product variation feature. Did you follow all the steps here http://docs.woothemes.com/document/product-variations/? The code is looking for a data-attribute called product_variations on the add to cart form which does not exist

If I switch to the Twenty Eleven theme, the product adds to the cart without issue. No warnings in console. Just made a new test product to ensure it wasn't a problem with the database migration. Same issue.

Script tries to get the product characteristics from the few places, but cannot reach that, as it is defined in a different way.
May be it is an issue of the particular theme or a theme version is old or something else.

I believe the easiest way to make it works properly is to add the next code after the comments on line 128 at add-to-cart-variation.min.js file:

if ( !all_variations )
    all_variations = window["product_variations_" + product_id];
Worked great! Thanks :)
