The icon_dirs hook in WordPress is used to specify the directories where custom icon sets are located. This hook allows developers to add their own custom icon sets to be used within the WordPress admin interface.

The icon_dirs hook is located within the wp-includes/functions.php file in WordPress. It is part of the process that determines the directories where custom icon sets can be found and utilized within the WordPress admin interface.
Hook Parameters (if applicable): icon_dirs
The icon_dirs hook does not accept any arguments or parameters. It simply allows developers to specify the directories where custom icon sets are located.
Hook Doesn’t Work: icon_dirs
If the icon_dirs hook doesn’t work as expected, it may be due to incorrect directory paths specified by the developer. It is important to ensure that the directory paths provided in the hook are accurate and accessible within the WordPress installation.
Best Practices & Usage Notes (if applicable): icon_dirs
When using the icon_dirs hook, it is important to note that the custom icon sets must be properly formatted and compatible with the WordPress admin interface. Additionally, developers should ensure that the directory paths specified in the hook are valid and accessible.
Usage Example: icon_dirs
“`php
function custom_icon_dirs( $dirs ) {
$dirs[] = ‘/path/to/custom/icon/sets’;
