Description

Checks for "Network: true" in the plugin header to see if this should be activated only as a network wide plugin. The plugin would also work when Multisite is not enabled.

Checks for "Site Wide Only: true" for backward compatibility.

Usage

$bool = is_network_only_plugin( $plugin );

Parameters

$plugin

( string ) required – Path to the plugin file relative to the plugins directory.

Returns

bool True if plugin is network only, false otherwise.

  $plugin_data = get_plugin_data( WP_PLUGIN_DIR . '/' . $plugin );

  }
  return false;
}
