CiviCRM Community Forums (archive)

Hi I've been looking around the forums and have found a couple of subjects on this but nothing recent that's definitive.

When a person registers for an event, I'd like to validate the fields for

email (something@something.com)
phone - xxx-xxx-xxxx
fax - same thing

Can someone point me in the right direction?

Thanks,
Greg

sample code for e-mail address on a contribution page

function grammy365_membership_civicrm_validate( $formName, &$fields, &$files, &$form ) {
    $session =& CRM_Core_Session::singleton();
    $contactId = $session->get( 'view.id' );
    switch ($formName) {
      case 'CRM_Contribute_Form_Contribution_Main': //Contribution Page
   if (isset($fields['email-5'])) {
     $email = $fields['email-5'];
     if (valid_email_address($email) != TRUE) {
       $errors['email-5'] = ts( "The e-mail appears to be invalid" );
     }    
   }
        break;
    }
  return empty( $errors ) ? true : $errors;
}
