What are hooks in WordPress?
In WordPress, hooks are connecting points that allow developers to customize and extend the behavior of WordPress without directly modifying the core. Themes and especially plugins are relying on hooks to work properly.
WordPress hooks are divided into two types: action hooks and filter hooks.
Action hooks are connecting points that allow developers to add additional content or functionality at various points in the WordPress code.
For example, a developer can use an action hook to add a contact form to the WordPress home page or to send an email when a user registers on a WordPress site.
Filter hooks are connecting points that allow developers to modify the content or data generated by WordPress before it is displayed on the site.
For instance, a developer can use a filter hook to add HTML tags to a page title before it is displayed on the site, or to replace one word with another in the content of a WordPress post.
In summary, hooks make WordPress highly flexible and allows developers to create unique and powerful websites without altering WordPress core.
