PHP WP_Automatic_Updater::update方法代码示例

 /**
  * Check for Updates at the defined API endpoint and modify the update array.
  *
  * This function dives into the update API just when WordPress creates its update array,
  * then adds a custom API call and injects the custom plugin data retrieved from the API.
  * It is reassembled from parts of the native WordPress plugin update code.
  * See wp-includes/update.php line 121 for the original wp_update_plugins() function.
  *
  * @uses api_request()
  *
  * @param array   $_transient_data Update array build by WordPress.
  * @return array Modified update array with custom plugin data.
