Add Conditional check function

Hi. I needed to restrict access to a custom post type page in a plugin that was using quite a bit of custom meta to display various parts of the page, so simply filtering the content wasn’t getting it done.

I modified the user_specific_content_filter() to create a bausp_user_is_allowed() conditional check. I went wrong somewhere because the filter seems to allow for admin users to see the content, but this does not.

I’d love to see this kind of conditional template tag rolled in to the plugin. What I added is as follows

public function bausp_user_is_allowed() {
		global $post;
		global $user;
		global $current_user;
		$savedoptions = get_post_meta($post->ID, 'U_S_C_options',true);
		$m = get_post_meta($post->ID, 'U_S_C_message',true);
		if (isset($savedoptions) && !empty($savedoptions)){
			// none logged only
			if (isset($savedoptions['non_logged']) && $savedoptions['non_logged'] == 1){
				if (is_user_logged_in()){
					echo 'is_user_logged_in()';
					return false;
				}
			}
			//logged in users only
			if (isset($savedoptions['logged']) && $savedoptions['logged'] == 1){
				if (!is_user_logged_in()){
					echo 'failed !is_user_logged_in()';
					return false;
				}
			}
		}
		$savedroles = get_post_meta($post->ID, 'U_S_C_roles',true);
		$run_check = 0;
		$savedusers = get_post_meta($post->ID, 'U_S_C_users',true);
		if (!count($savedusers) > 0 && !count($savedroles) > 0 ){
			return true;
			exit;
		}
		//by role
		if (isset($savedroles) && !empty($savedroles)){
			get_currentuserinfo();
			$cu_r = $this->bausp_get_current_user_role();
			if ($cu_r){
				if (in_array($cu_r,$savedroles)){
					return true;
					exit;
				}else{
					$run_check = 1;
				}
			}else{
				//failed role check
				$run_check = 1;
			}
		}
		//by user
		if (isset($savedusers) && !empty($savedusers)){
			get_currentuserinfo();
			if (in_array($current_user->ID,$savedusers)){
				return true;
			}else{
				$run_check = $run_check + 1;
			}
			//failed both checks
			echo 'failed both checks';
			return false;
		}
		if ($run_check > 0){
			echo 'failed $run_check > 0';
			return false;
		}
		return true;
	}
