Better integrate Flamingo’s admin menu with Contact Form 7

I didn’t like how Flamingo was managed in admin when all I really wanted was a “Submissions” link added to Contact Form 7’s submenu. Here’s some code that fixed that for me, just pop it in your functions.php file or use the Code Snippets plugin.

add_action( 'admin_menu', '_wp_flamingo_humility', 999 );
function _wp_flamingo_humility() {

  // Only do if Contact Form 7 is active
  if ( !is_plugin_active( 'contact-form-7/wp-contact-form-7.php' ) ) return;

  // More descriptive CF7 menu label
  $wpcf7_menu = _get_menu_index_by_slug( 'wpcf7' );
  $GLOBALS['menu'][$wpcf7_menu][0] = __('Forms', 'textdomain');

  // Optional: Hide CF7 "Integration" submenu
  remove_submenu_page( 'wpcf7', 'wpcf7-integration' );

  // Only do if Flamingo is active
  if ( !is_plugin_active( 'flamingo/flamingo.php' ) ) return;

  // Drop default Flamingo admin menu
  remove_menu_page('flamingo');

  // Add "Inbound Messages" link to CF7 Menu with better menu label
  add_submenu_page(
    'wpcf7',
    __( 'Flamingo Inbound Messages', 'flamingo' ),
    __( 'Submissions', 'flamingo' ),
    'flamingo_edit_inbound_messages',
    'admin.php?page=flamingo_inbound'
  );
}

// Fix menu highlighting for Flamingo when moved to CF7 submenu
add_filter( 'parent_file', '_wp_flamingo_menu_highlight' );
function _wp_flamingo_menu_highlight( $parent_file ) {
  if (isset($_GET['page']) && $_GET['page'] == 'flamingo_inbound'){
    $GLOBALS['plugin_page'] = 'wpcf7';
    $GLOBALS['submenu_file'] = 'admin.php?page=flamingo_inbound';
  }

  return $parent_file;
}

// Helper function to find admin menu index by slug
function _get_menu_index_by_slug( $location = '' ) {
  foreach ( $GLOBALS['menu'] as $index => $menu_item ) {
    if ( $location === $menu_item[2] ) {
      return $index;
    }
  }
  return false;
}

This is just a *bump* of a tip I posted a few years ago.
