It may happen that you are designing some sort of archive page or a front page and you want to list all posts belonging to a specific category. In this case you can use WP_Query (or the simpler get_posts() helper) to pull in exactly the posts you need.

Everyone who’s used Git for long enough has committed something they didn’t mean to — a debug print left in, a config file with the wrong values, a commit message that’s just “wip.” The fix depends entirely on one question: has that commit been pushed anywhere yet? This post walks through both cases. It’s the twelfth post in this site’s Git command guide, following Git Log.

The traditional approach loads scripts unconditionally on every page, whether they’re needed or not, and gives WordPress no way to manage load order or avoid duplicate copies of the same library. Registering scripts with wp_register_script() (and loading them with wp_enqueue_script()) lets WordPress handle dependencies, versioning, and placement for you, which keeps your site faster and your script loading predictable.
Use the following syntax to register a script. This is typically called inside a function hooked to wp_enqueue_scripts (more on that below).
wp_register_script( $handle, $src, $deps, $ver, $in_footer );

Git has a built-in typo handler that most people never turn on: help.autocorrect. By default Git just suggests the command it thinks you meant, but you can configure it to run the correction automatically, with or without a delay. This is the thirteenth and last post in this site’s Git command guide — a smaller, more personal config topic to close out with, following Git: Delete Last Commit.
show_admin_bar filter hides the bar sitewide for every user, while the show_admin_bar_front user meta lets you hide it for a specific user only.
add_filter( 'show_admin_bar', '__return_false' );// Hide admin bar for the current user only
update_user_meta( get_current_user_id(), 'show_admin_bar_front', false );An AJAX loading overlay is a UI element that covers the page (or a section of it) while an asynchronous request is in progress. It prevents users from clicking a button multiple times and gives clear visual feedback that something is happening in the background.
