Valdiate Email address

Hi @itsmir

I hope you are doing well today.

I pinged our Forminator & SLS Team to review your query to see what will be possible in this matter. We will post an update here as soon as more information is available.

Kind Regards,
Kris

Hi @itsmir

Just as a refer for you and future queries this is the code which you can use as a mu-plugin

add_filter( 'forminator_custom_form_submit_errors', 'wpmudev_limit_email_submission', 9999, 3 );
function wpmudev_limit_email_submission( $submit_errors, $form_id, $field_data_array ) {
	if ( $form_id != 6 ) { //Please change the form ID
		return $submit_errors;
	}

	$submitted_data = wp_list_pluck( $field_data_array, 'value', 'name' );

    if ( ! empty( $submitted_data['select-1'] ) && ! empty( $submitted_data['email-1'] ) ) {
        if ( $submitted_data['select-1'] == $submitted_data['email-1'] ) {
            $submit_errors[]['email-1'] = __( 'E-Mail Not Allowed.', 'forminator' );
        }
    }

	return $submit_errors;
}

This snippet should help. 6 should be changed to your form ID and select-1, email-1 should be changed to your select field and email field’s ID.
