Field validation is the most fundamental requirement and an absolutely must feature in any ecommerce platform and there is not a single web site or web store that does not have these sanity checks built in. Being a full featured ecommerce platform, Magento also supports field validation out of the box, and enables you to easily add basic validation checks on form fields.
Since Magento uses the Prototype library for field validation, which houses the implementation methods for all the field validation options the platforms offers, all you need to do when writing a custom form is to assign valid class names to your input fields, in order to automatically implement the relevant field validation checks on them.
The list below shows the most popular field validations used in Magento, which are supported out of the box.
