WordPress hooks allow developers to add custom functionality to a website without modifying the core code. They allow developers to insert custom code at specific points in the WordPress code, called “actions” or “filters.”
Types of hooks in WordPress:
Actions: These hooks allow developers to insert custom code at specific points in the WordPress code, such as when a post is published, or a user logs in.
Filters: These hooks allow developers to modify the output of WordPress functions and classes, such as the content of a post or the title of a page.
Hooks are implemented using the functions add_action() and add_filter(). For example, to add a custom function to the hook “publish_post,” a developer would use the following code:
WordPress hooks are a powerful tool for developers, allowing them to add custom functionality to a website without modifying the core code. They also make updating the website and maintaining the custom functionality easier. However, it’s important to remember that using hooks can make the code harder to maintain and harder to troubleshoot issues.
