Email Validation filter function on two forms

  • Hello all,

    I’m using two CF7 forms on a single WP website – Form 1 and Form 2 – for which users are requested to fill in an email address. For validation purposes I ask them to repeat their email address (to eliminate/reduce the risk of typos) and use the filter function used for the validation as described here:

    https://contactform7.com/2015/03/28/custom-validation/

    Form 1 uses the following email name tags:

    <label> Email-Address 
    [email* your-email-1 autocomplete:email placeholder "Your Email-Address"] </label>
<label> Repeat Email-Address 
    [email* your-email-confirm-1 autocomplete:email placeholder "Please repeat your Email-Address"] </label>

    and Form 2 uses these email name tags:

    <label> Email-Address 
    [email* your-email-2 autocomplete:email placeholder "Your Email-Address"] </label>
<label> Repeat Email-Address 
    [email* your-email-confirm-2 autocomplete:email placeholder "Please repeat your Email-Address"] </label>

    In the theme functions.php I have added the following filter function taken from the contactform7 website (see link above) for validating the email address in Form 1. That’s working perfectly fine.

    add_filter( 'wpcf7_validate_email*', 'custom_email_confirmation_validation_filter', 20, 2 );
  
function custom_email_confirmation_validation_filter( $result, $tag ) {
  if ( 'your-email-confirm-1' == $tag->name ) {
    $your_email = isset( $_POST['your-email-1'] ) ? trim( $_POST['your-email-1'] ) : '';
    $your_email_confirm = isset( $_POST['your-email-confirm-1'] ) ? trim( $_POST['your-email-confirm-1'] ) : '';
  
    if ( $your_email != $your_email_confirm ) {
      $result->invalidate( $tag, "Please check your Email-Address" );
    }
  }
  return $result;
}

    How would I amend the filter function above in order to add the same email validation in form 2 with the name tags below (and have the function keep working in Form 1)?

    [email* your-email-2]
and
[email* your-email-confirm-2]

    Any help greatly appreciated!

    Thank you very much!

    I was able to figure this out myself. In case anyone has a similar task to solve, the following filter works for my case above, i.e. 2 forms with independent Email-Address validation.

    add_filter( 'wpcf7_validate_email*', 'custom_email_confirmation_validation_filter', 20, 2 );
  
function custom_email_confirmation_validation_filter( $result, $tag ) {
  if ( 'your-email-confirm-1’ == $tag->name ) {
    $your_email_1 = isset( $_POST['your-email-1'] ) ? trim( $_POST['your-email-1'] ) : '';
    $your_email_confirm_1 = isset( $_POST['your-email-confirm-1’] ) ? trim( $_POST['your-email-confirm-1’] ) : '';
  
    if ( $your_email_1 != $your_email_confirm_1 ) {
      $result->invalidate( $tag, "Please check your Email-Address" );
    }
  }
  if ( 'your-email-confirm-2' == $tag->name ) {
    $your_email_2 = isset( $_POST['your-email-2’] ) ? trim( $_POST['your-email-2’] ) : '';
    $your_email_confirm_2 = isset( $_POST['your-email-confirm-2'] ) ? trim( $_POST['your-email-confirm-2'] ) : '';
  
    if ( $your_email_2 != $your_email_confirm_2 ) {
      $result->invalidate( $tag, "Please check your Email-Address" );
    }
  }
  
  return $result;
