Note: This tutorial is for ChronoForms v3 only.

ChronoForms includes a range of common validations but they don’t meet every need. Because ChronoForms uses the LiveValidation library it’s fairly easy to add custom validations.

Level: advanced, requires some JavaScript knowledge.

This How-to document links to Chapter 5 ‘Form Validation and Security’ of the “ChronoForms 1.3 for Joomla! sites cookbook”.

Contents include:

• A simple custom LiveValidation;
  
• Validating morethan one field;
  
• Validating dates using Regular Expressions;
  
• Validating other things using Regular Expressions;
  
• Using other LiveValidation validations;
  
• Customising LiveValidation error messages
