When a customer presses the continue button on the order screen (shopcustomer.asp) and it fails with mandatory-fields not being entered, the error message is easy to miss, and it's also annoying that the entire screen "posts" before you get to see the error.

This module will display the relevant error message as an alert as soon as the user presses the "continue" button (ie client/browser-side) and when an error occurs the page won't "post" until they correct the problem and press "continue" again, and the cursor will automatically focus on the failed field.

It also allows you to specify maximum and/or minimum lengths of values that you want to allow for a given field, and also gives you an email-format validation option for email fields.

Makes the customer ordering process much more intuitive/friendly, and so should lead to less dropped carts too.


Technical/Developer Information:
There's a config file where you specify the fields that you want validated, and for each field you can say whether you want it to be a mandatory field, have a minimum length allowed, and/or a maximum length allowed, and you specify what the "description" of the field is (for error message construction).

To add validation for another field, you simply add another line to the config file for it. All the javascript code is created for you on the fly by the asp code that you call from the shopcustomer.asp screen.

The construction of the error message text is also split into separate config files for different types of failures, so you can easily change the general formatting/language of the alerts.

Very easy to install too; just a handful of lines to paste into shopcustomer.asp.
