This module uses Ajax and jQuery to check for available stock and if there is
no stock available, it replaces the 'Add to cart' button with a configurable

Display attributes types supported for AJAX validation:

  • Select box
  • Radio buttons

It provides server-side validation so this module can prevent the addition of
out of stock items even if Javascript is disabled or if the user clicks on an
"Add to cart" button too quickly.

Validations of stock are performed on the following places, throwing error
messages accordingly:

  • Single product add to cart forms (teaser, full and catalog view): If an
    item out of stock or, if the item you want to add is already on your cart
    but you have reached the stock limit.
  • Shopping cart form: If you try to add more items that the ones in stock of
    any product of your shopping cart.
  • Order checkout and order review form: If the stock information has changed
    while the user is browsing the site (i.e. same item has just been bought
    by another user).

Display attributes type NOT supported - they don't add variations to SKU, so
are not related to stock control:

  • Text field
  • Checkboxes
