What is WordPress Hook: get_tags
The get_tags hook in WordPress is used to retrieve a list of tags from the database. It allows developers to modify the tag query before it is executed, providing a way to customize the results.

The get_tags hook is located within the get_terms() function, which is responsible for retrieving terms from the database. It is specifically used for tags and allows developers to modify the tag query arguments before the database is queried.
Hook Parameters (if applicable): get_tags
The get_tags hook accepts parameters such as $args, $taxonomies, and $args_overrides. These parameters allow developers to customize the tag query by specifying the taxonomy, the query arguments, and any additional overrides.
Hook Doesn’t Work: get_tags
If the get_tags hook doesn’t work as expected, it may be due to incorrect usage of the parameters or conflicting code within the theme or plugins. To troubleshoot, developers should check for any conflicting code and ensure that the parameters are being used correctly.
Best Practices & Usage Notes (if applicable): get_tags
When using the get_tags hook, it’s important to note that modifying the tag query can impact the performance of the website. Developers should use this hook sparingly and consider the potential impact on database queries. Additionally, it’s recommended to test any modifications thoroughly to ensure they produce the desired results.
Usage Example: get_tags
“`php
function custom_tag_query( $args ) {
// Modify the tag query arguments
$args[‘orderby’] = ‘count’;
$args[‘order’] = ‘DESC’;
return $args;
}
add_filter( ‘get_tags’, ‘custom_tag_query’ );
“`
In this example, the get_tags hook is used to modify the tag query arguments to order the tags by count in descending order. This allows developers to customize the tag query to suit their specific needs.
