Validate submit event field Snippets

Validation refers to the process of checking the accuracy of the information provided. When an event is posted on a website, it determines the credibility of the organizer. Hence it becomes of utmost importance to provide the details accurately.

The following steps must be taken to check validation on a particular field while submitting an event form:

1. Open your child theme’s function.php file.
2. Add the following code:

   add_filter('submit_event_form_validate_fields', 'wpem_submit_event_form_validate_fields', 10, 3);
      function wpem_submit_event_form_validate_fields($string, $fields, $values)
       {
           foreach ( $fields as $group_key => $group_fields )
           {
               foreach ( $group_fields as $key => $field ) 
               {            
                   if($key == 'phone_no')
                   {
                       if(strlen($values[$group_key][$key]) <= 10)
                       {
                           return new WP_Error( 'validation-error', __( 'Please Enter 10 Digit Number', 'wp-event-manager' ) );
                       }
                   }
               }
           }
           return $string;
       }
