Valid Cart

A Zen Cart™ mod which allows you to specify conditions under which customers may not check out.

Relevance: Zen Cart™ 1.3.6 and forward

Cost: Starting at $60, more for very complex validations

Support Thread: My commercial software is not supported on the Zen Cart forum. Please email me questions instead.

See it Live: Go to my demo shop and add an item costing less than $100 to your cart. You will immediately see an error message on the shopping cart page and on the shipping page because the validation "shippable total must be greater than $100" was used.

Overview:

This mod permits you to set preconditions on the checkout process. Any rule which is appropriate for your business may be implemented as a validity check. Some sample rules are:

• If good from category <x> are purchased, goods from category <y> must be purchased.
• A minimum number of goods from one particular category or group of categories must be purchased.
• If any goods from category <x> are purchased, a minimum number must be purchased.
• Validations requiring groupings of goods from top level categories and subcategories
• Only customers from certain countries may purchase certain products (or any products)

Invalid Checkout Page

The continue checkout button is not displayed; your customers cannot continue checking out until they resolve the problem.

Invalid Shopping Cart Page

On the Shopping Cart page, the message is displayed in the error style, and the checkout button is hidden. Again, your customers cannot checkout until they resolve the problem.

  I charge a fee starting at $60 for this extension depending on the complexity of your validations. Please contact me with your requirements for details.
