What is WordPress Hook: init
The init hook is a fundamental hook in WordPress that is triggered after WordPress has finished loading but before any headers are sent. It is an essential hook for developers to use when they need to perform actions or add filters at the beginning of the WordPress process.
Understanding the Hook: init
The init hook is located within the WordPress process and is used to initialize certain aspects of the site. It is often used to register post types, set up constants, or perform other actions that need to occur early in the WordPress load process.
Hook Parameters (if applicable): init
The init hook does not accept any arguments or parameters.
Hook Doesn’t Work: init
If the init hook doesn’t seem to be working, it could be due to the hook being called too late in the process. It’s important to ensure that the init hook is being used in the appropriate context and at the right time in the WordPress load process.
Best Practices & Usage Notes (if applicable): init
When using the init hook, it’s important to be mindful of the timing of the actions or filters being added. Since the init hook is called early in the WordPress load process, certain functions or features may not be available at this point. It’s best to use the init hook for tasks that specifically need to occur at the beginning of the WordPress process.
Usage Example: init
“`php
function custom_post_type_init() {
// Register custom post type
}
add_action(‘init’, ‘custom_post_type_init’);
“`
In this example, the init hook is used to register a custom post type early in the WordPress load process. This ensures that the custom post type is properly initialized and available for use throughout the rest of the site.
