frm_filtered_lookup_options

Last Updated: June 12, 2018

Knowledge Base → Extend Formidable Forms → Formidable Hooks - for Developers → Field Options and Values → frm_filtered_lookup_options
Heads up!
This article contains PHP code and is intended for developers. We offer this code as a courtesy, but don't provide support for code customizations or 3rd party development.

Modify the options included in a lookup field before they are displayed in the form.

Usage

add_filter( 'frm_filtered_lookup_options', 'change_lookup_options', 10, 2 );

Parameters

  • $field (object) - the field the lookup field is using
  • $args (array)
    • limit (int) - the maximum number of options to include in the lookup field

Examples

Add extra content to lookup options

This example adds more content around the values shown in a lookup field. It changes the options like '2.1', '2.2' to 'Version 2.1 is updated', 'Version 2.2 is updated'.

add_filter( 'frm_filtered_lookup_options', 'change_lookup_options', 10, 2 );
function change_lookup_options( $options, $args ) {
  if ( $args['field']->id == 25 ) { // change 25 to the id of the field in the other form
    foreach ( $options as $k => $option ) {
      $options[ $k ] = 'Version ' . $option . ' is updated';
    }
  }
  return $options;
}

Display User ID field with display name and ID in Lookup Field

There may be times when you want to use a Lookup field mapped to a User ID field from another form. By default, the User ID is shown rather than the display name. You can show the display name and the user ID as options with this example.

add_filter( 'frm_filtered_lookup_options', 'change_lookup_options', 10, 2 );
function change_lookup_options( $options, $args ) {
  if ( $args['field']->id == 808) { // change 808 to the id of the user ID field from the other form
    foreach ( $options as $k => $option ) {
      $user = get_user_by('id', $option);
      $value = $user->display_name;
      $options[ $k ] = $value . ' - ID ' . $option;
    }
  }
  return $options;
}

Replace 808 with the User ID field in your other form (the one that the lookup field is mapped to).
