Does This Custom Caching Code Interfere with WP REST Cache?

Hi @hassantafreshi

Thank you for using our plugin!

First of all we use the Transients API to store our caches instead of the Object Cache because we want persistent caches regardless of any persistent cache plugin being installed. However if a persistent cache plugin is installed the transients API will use the wp_cache_get and wp_cache_set functions.

Now to your question: will there be any conflicts? I don’t think so because we use different cache keys. Only if those keys would match a conflict would occur. The odds of that happening are very limited since all our cache keys start with wp_rest_cache_ and then a hash of the requested URI. Since all your caches are prefixed with efb there will be no conflicts.

Thank you for the quick response. We use the following function to handle page caching with plugins. Do you have a structure similar to other plugins that we can add to solve the caching issue?

public function cache_cleaner_Efb($page_id){

        if (defined('LSCWP_V') || defined('LSCWP_BASENAME' )){

            //litespeed done            

            do_action( 'litespeed_purge_post', $page_id );

        }else if (function_exists('rocket_clean_post')){

            //wp-rocket done                    

            $r = rocket_clean_post($page_id);          

        }elseif (function_exists('wp_cache_post_change')){

            //WP Super Cache done          

            //Jetpack done

            $GLOBALS['super_cache_enabled']=1;

            wp_cache_post_change($page_id);

        }elseif(function_exists('autoptimize_filter_js_noptimize ')){

            //auto-Optimize done

            autoptimize_filter_js_exclude(['jquery.min-efb.js','core-efb.js']);

            autoptimize_filter_js_noptimize();

        }elseif(class_exists('WPO_Page_Cache')){

            //WP-Optimize done

            \WPO_Page_Cache::delete_single_post_cache($page_id);

        }elseif(function_exists('w3tc_flush_post')){

            //W3 Total Cache done          

            w3tc_flush_post($page_id);

        }elseif(function_exists('wpfc_clear_post_cache_by_id')){

            //WP Fastest Cache done

            wpfc_clear_post_cache_by_id($page_id);

        }elseif(has_action('wphb_clear_page_cache')){

            //Hummingbird done          

            do_action( 'wphb_clear_page_cache', $page_id );

        }

    }

Hi @hassantafreshi

You could use this:

\WP_REST_Cache_Plugin\Includes\Caching\Caching::get_instance()->delete_related_caches( $post_id, $object_type );

Where $post_id in your case would be $page_id and $object_type is the post type of the item (so 'page' ?).

@rockfire
Thank you for your response. Is there a way to clear the cache in your plugin using only the post_id? Specifically, I want to clear the cache for a specific page by referring to its post_id in the cache deletion function.

Hi @hassantafreshi

At this point we do not have a function for that. The reason you need to specify it, is because the object type can be a post type or a taxonomy. So based only on the ID we can not say for sure what the object type is (a page can have the same ID as a term)

Thank you for your response. Could you please clarify the value of the $object_type variable? Given our situation, could you provide guidance on how we can assist users of both plugins effectively?

Thank you.

Hi @hassantafreshi

$object_type is the type of the object with ID $post_id (the name of that variable is maybe not very well chosen ??). Meaning: if $post_id refers to a post of a (custom) post type, $object_type is the slug of that (custom) post type. But if $post_id refers to a (custom) taxonomy term, $object_type is the slug of that (custom) taxonomy.

Some example to hopefully make it more clear:

Example 1:
We have a page with ID = 42:
$post_id = 42
$object_type = 'page'

Example 2:
We have an event (= custom post type) with ID = 43:
$post_id = 42
$object_type = 'event'

Example 3:
We have a category with term ID = 44:
$post_id = 44
$object_type = 'category'

Example 4:
We have an event category (= custom taxonomy) with ID = 45:
$post_id = 45
$object_type = 'event_category'

@rockfire Thank you for your detailed explanation. This kind of thing always happens when naming variables during development ??

I have added these code , what you think ?

case 'wp-rest-cache':
					//\WP_REST_Cache_Plugin\Includes\Caching\Caching::get_instance()->delete_related_caches( $post_id, $object_type );
					$typPage = get_post_type($page_id);
					if(class_exists('\WP_REST_Cache_Plugin\Includes\Caching\Caching')) \WP_REST_Cache_Plugin\Includes\Caching\Caching::get_instance()->delete_related_caches( $page_id, $typPage );
				break;
