To Validate a Form Element Add the Custom Attribute: validate="VALIDATEHOW"
Your Current Options Are:
"not_empty"
"integer"
"number" - decimal allowed
"email"
"phone" - includes international phone numbers
Multiple Validation uses the following syntax:
validate="not_empty|integer"
To Add a Message Add the Custom Attribute:
msg="Name is a required field" By Default the Messages are shown next to the form element.
To Show Alert Boxes add a Custom Attribute in the form tag (show_alert):
ADVANCED USERS: Add Your Own Function Calls to the validate attribute. It Must return true or false example:
