If I did understand well, we need to cache a value retrieved from another REST service, from the login to logout of the user on the wordpress installation, so we will hook into this wp_login to get the value and cache it using Transient API, Options API or a persistent caching plugin. add_action(‘wp_login’, ‘my_get_and_cache_rest_value’); function … Read more
You could just write your own query, too. That way, it’s one query per category: global $wpdb; $query = ‘ SELECT wpp1.* FROM ‘ . $wpdb->posts . ‘ AS wpp1 LEFT JOIN ‘ . $wpdb->term_relationships . ‘ AS wptr1 ON wptr1.object_id = wpp1.ID WHERE post_type = %s AND post_status = %s AND wptr1.term_taxonomy_id = %d … Read more
You are using transient API which works storing data on wp_options table by default. That means that additional database queries will be performed to set the transient and to get the transient. With your code the number of queries should be less for non-logged in users in second and subsequent visits when the transient exists … Read more
The example your using from the codex adds and removes it (probably not something you want to do), and is not very clear. By default WordPress will cache the feed for 12 hours using wp_feed_cache_transient_lifetime, the actual code WP uses for 12 hours is $lifetime = 43200 If you want to alter the cache time … Read more
your problem is not with the admin pages themself, they are simply not big enough to be hugely impacted by slow connection, but with JS and CSS files. You can set an expiry date for them which will signal to the browser it may cache them until that time. To cache them for a week … Read more

First get datetime stamp of your js file’s last modification, and use it as fourth parameter of wp_enqueue_script function: $path=”full path to your script file”); $handle=”your_handle”; $src=”https://wordpress.stackexchange.com/questions/283374/path of the script, relative to the WordPress root directory”; $depts = array(); // dependencies, if any $ver = filemtime($path); $in_footer = false; wp_enqueue_script($handle, $scr, $depts, $ver, $in_footer); If … Read more
In WordPress v2.5+ the object cache is not persistent. It will save things in memory, but for persistent caching across page loads you will need a plugin see here: http://codex.wordpress.org/Class_Reference/WP_Object_Cache#Persistent_Caching Alternatively, use transients, which are persistent. The identifier must be 45 or less characters long, but the data attached to that identifier can be longer. … Read more
According with WP Object API documentation both functions accepts these arguments: $key: the key to indicate the value. $data: the value you want to store. $group: (optional) this is a way of grouping data within the cache. Allows you to use the same key across different groups. $expire: (optional) this defines how many seconds to … Read more
“Quick” fix: Right Click -> view page source ( ctrl+U ), find .css file you changed, open it in new tab and reload ( you should see change in place you’ve made it ) ONLY in development mode add php function time() in place of version number wp_enqueue_style( $handle, $src, array(), time() , ‘all’ ); … Read more
