Insert the SDK in plugin main file. The following SDK is only an example. You can create your custom pluginEye SDK at: https://www.plugineye.com/ /** * @author PluginEye * @copyright Copyright (c) 2019, PluginEye. * @version 1.1.1 * @license https://www.gnu.org/licenses/gpl-3.0.html GNU General Public License Version 3 * PLUGINEYE SDK */ require_once('plugineye/plugineye-class.php'); $plugineye = array( 'main_directory_name' => 'main_directory_name', 'main_file_name' => 'main_file_name.php', 'redirect_after_confirm' => 'admin.php?page=my_options.php', 'plugin_id' => '1', 'plugin_token' => 'NWNmN2MwYjBkZTg3ZTU5NmQmM4N2E4NzhmOTdkMDdhMTYzMjg1YTBhM2VlOThjNmU3YThlMDQ1OWE4Y2I=', 'plugin_dir_url' => plugin_dir_url(__FILE__), 'plugin_dir_path' => plugin_dir_path(__FILE__) ); $myclass = new pluginEye($plugineye); $myclass->pluginEyeStart(); Add 'plugineye' directory in top level plugin directory.
