A similar hook as wp_head for the admin area
The alternative to wp_head action in admin area is admin_head. But, if your CSS depends on another stylesheet, you should use wp_add_inline_style() function hooked to admin_enqueue_scripts action.

WordPress scheduled task is called but not executed
I was having the same issue recently, until I followed an example from the WordPress Codex which suggests using action hooks to run the function. I think if you add the following… add_action( ‘recalculate_all_scores_hook’, ‘recalculate_all_scores’ ); …and amend the wp_schedule_event function to use the action hook name rather than the function directly… wp_schedule_event( time(), ‘fiveminutes’, … Read more
new WP_Query() – what is the earliest valid hook?

This seems to work, but I would be interested in hearing from others if it’s the “correct” way to provide this sort of override. I’m assuming you’re visiting a category archive page, like http://www.example.com/category/computers/. // landing page = 188 // category = “computers” (#8) function custom_wpquery( $query ){ // the main query global $wp_the_query; if … Read more

Extending WP_User class and using this sub-class during the whole lifecycle
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

When we fire up: do_action( ‘foo’ ); we are actually calling: do_action( ‘foo’, ” ); That’s because how it’s defined; With the empty string as the default input argument: function do_action($tag, $arg = ”) { // … } So the action’s callback get’s the empty string as it’s first input argument.
