# PHP Warning

 * Hi Alin,
 * I have been getting a PHP Warning, I believe since the last plugin update:
 * > call_user_func_array() expects parameter 1 to be a valid callback, class ‘GADWP_Tracking’
   > does not have a method ‘tracking_code’ in /public_html/wp-includes/class-wp-
   > hook.php on line 298
 * As per [this topic](https://wordpress.org/support/topic/exclude-from-dynamic-pages/)
   from over a year ago, I have the following code in a custom functions file:
 *     ```
       add_action('init', 'ngadwp_move_trackingcode');
       function ngadwp_move_trackingcode(){
       	if (class_exists('GADWP_Manager')){
       		$gadwp = GADWP();
       		if (isset($gadwp->tracking)){
       			remove_action('wp_head', array($gadwp->tracking,'tracking_code'), 99);
   
       			$uri = $_SERVER["REQUEST_URI"];
       			$uri_array = split("/",$uri);
       			$uri_first = $uri_array[1];
       			$uri_second = $uri_array[2]; // select the second split (domain does not count as split)
   
       			if ( ($uri_first == 'subscriptions') && ( ($uri_second == 'manage')  || ($uri_second == 'confirmation') || ($uri_second == 'unsubscribe') || ($uri_second == 'comments') ) ) {
       			} else {
       				add_action('wp_footer', array($gadwp->tracking,'tracking_code'), 0);
       			}
       		}
       	}
       }
       ```
   
 * I imagine there’s now a conflict with the new settings to choose the positioning
   of the tracking code. I haven’t touched those, waiting to see if my code would
   continue to work. It does, as far as I can tell, but I’d like to figure out how
   to get rid of the error message flooding my error logs. I assume the above code
   is no longer needed to move the tracking code to the footer, as I can now use
   your built-in settings, so removing it would probably do the trick, but I still
   need to exclude the tracking code from certain pages. Is there a way to modify
   the above code to do just that?
 * Thanks for your help!

 * Hi,
 * The tracking component changed a lot, here’s the new code. I haven’t tested it,
   so please drive some tests first:
 *     ```
       add_action('init', 'ngadwp_remove_trackingcode');
       function ngadwp_remove_trackingcode(){
       	if (class_exists('GADWP_Manager')){
       		$gadwp = GADWP();
       		if (isset($gadwp->tracking->analytics)){
   
       			$uri = $_SERVER["REQUEST_URI"];
       			$uri_array = split("/",$uri);
       			$uri_first = $uri_array[1];
       			$uri_second = $uri_array[2]; // select the second split (domain does not count as split)
   
       			//Remove tracking for these URIs
       			if ( ($uri_first == 'subscriptions') && ( ($uri_second == 'manage')  || ($uri_second == 'confirmation') || ($uri_second == 'unsubscribe') || ($uri_second == 'comments') ) ) {
       				// Remove GA Tracking Code
       				if ( $gadwp->config->options['trackingcode_infooter'] ) {
       					remove_action( 'wp_footer', array( $gadwp->tracking->analytics, 'output' ), 99 );
       				} else {
       					remove_action( 'wp_head', array( $gadwp->tracking->analytics, 'output' ), 99 );
       				}
       				// Remove Optimize code
       				if ( $gadwp->config->options['optimize_tracking'] && $gadwp->config->options['optimize_pagehiding'] && $gadwp->config->options['optimize_containerid'] ) {
       					remove_action( 'wp_head', array( $gadwp->tracking->analytics, 'optimize_output' ), 99 );
       				}
       				// Remove AMP code
       				if ( $gadwp->config->options['amp_tracking_analytics'] ) {
       					remove_action( 'amp_post_template_head', array( $gadwp->tracking->analytics, 'amp_add_analytics_script' ) );
       					remove_action( 'amp_post_template_footer', array( $gadwp->tracking->analytics, 'amp_output' ) );
       				}
       			}
       		}
       	}
       }
       ```

 * Thanks very much for this, Alin! It works for removing the code from the desired
   pages, and it looks like it solves the issue of the PHP warning as well 🙂
