WordPress is a powerful content management system that offers plenty of features to its users. One of the most useful functions that WordPress provides is the get_current_screen() function. This function retrieves information about the current admin screen in WordPress.
The get_current_screen() function returns an object that contains various properties such as the screen ID, the screen base, the parent base, the parent file, etc. These properties provide useful information about the current screen, which can be used to customize the behavior of the WordPress admin.
The get_current_screen() function is often used in plugin and theme development to add custom functionality to the WordPress admin based on the current screen. For example, you might want to add a custom meta box to the post edit screen, or you might want to add a custom column to the user list table. To do this, you can use the get_current_screen() function to retrieve information about the current screen and then use that information to customize the admin interface.
Here’s an example usage code of the get_current_screen() function:
$current_screen = get_current_screen();
if ( $current_screen->id == 'edit-post' ) {
// Add custom meta box to the post edit screen
add_meta_box( 'custom-meta-box', 'Custom Meta Box', 'custom_meta_box_callback', 'post', 'normal', 'high' );
}In this example, we use the get_current_screen() function to retrieve information about the current screen. We then check if the current screen is the post edit screen (edit-post), and if so, we add a custom meta box to the screen using the add_meta_box() function.
Overall, the get_current_screen() function is a powerful tool that can be used to customize the WordPress admin interface and make it more user-friendly.
