Hi, there is a example code for Validate field in repeating section add_filter('frm_validate_field_entry', 'my_custom_validation', 10, 4); function my_custom_validation($errors, $posted_field, $posted_value, $args){ if($posted_field->id == 102){ //change to the ID of the field to validate if(!in_array($posted_value, array(123456,987654,234567))){ //enter your allowed values //if it doesn't match up, add an error: $errors['field'. $args['id']] = 'Not a Valid Serial Number'; } } return $errors; } But there will only one repeating field after the other be validated. Is there a hook to get all repeating fields of one section and check, if there is one entry used. Maybe I got the Entries 1,2,3,4,5,6 and the user got to use one time the entry 4. How can I validate, if the user has used this entry? Greetings, Mathias
