Input fields order change

Hi, it is possible, the easiest way to do that is to use the Custom Fields add-on https://wpadverts.com/extensions/custom-fields/, the more complicated way is to use the adverts_form_load filter

add_filter( "adverts_form_load", "customize_adverts_add" );
function customize_adverts_add( $form ) {
  if( $form['name'] != "advert" ) {
    return $form;
  }
  foreach( $form["field"] as $key => $field ) {
    if( $field["name"] == "_contact_information" ) {
      $form["field"][$key]["order"] = 15;   
    }
    if( $field["name"] == "_adverts_account" ) {
      $form["field"][$key]["order"] = 15;   
    }
    if( $field["name"] == "adverts_person" ) {
      $form["field"][$key]["order"] = 16;   
    }
    if( $field["name"] == "adverts_email" ) {
      $form["field"][$key]["order"] = 17;   
    }
    if( $field["name"] == "adverts_phone" ) {
      $form["field"][$key]["order"] = 18;   
    }
  }
  return $form;
}

The code you can add in your theme functions.php file.
