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:
MODIFICATIONS BY:
Graciela Travieso (graciela@cariaco.com)
New Function:
- Validate Email uses regular expession now
- Validate Zip Code
- Validate Password
- Password Confirmation
- Validate Credit Card Number
* ALERT NOTE:
- Validate the CC Number (MOD 10) against CC Type. CC Type must be the field BEFORE CC Number
- If CC Number is locate in a diferent position modify the value for "alt_element"
* PENDING CHANGES:
- To pas the incrementing/decrementing value for "alt_element" as ATTRIBUTE
- Validate Credit Card Expiration Date
- Validate Credit Card CID
