Validation API allows you to create validation rules (either Regular Expressions or PHP code) that can be applied to any field on your site.


  • Admin UI system to manage everything.
  • It will work with core fields, custom module form fields, CCK fields, etc.
  • You can create one validation rule that can be applied to as many fields on your site as you want.
  • Arguments can be used on validation rules to allow them to be flexible.
  • Links added to fields for a quick method to add validations to fields.
  • Validation rules can be added by another module using hook_add_validator (in addition to adding validators via the UI).
  • AJAX Validation is no longer included or supported with this project. Ajax Forms is the project to go to for your AJAX-addiction.

This project is apart of 2008 Google Summer of Code.
