hooks wp

WordPress hooks simplify developers integrating their code with the WordPress core, themes, and plugins. There are two types of hooks in WordPress:

  1. Actions Hooks
  2. Filters Hooks

Any WordPress user should learn about hooks, and they can aid you in the creation of functions or the editing of theme or plugin default settings.


A hook is a phrase used in WordPress to describe areas where you can add custom code or alter what WordPress does or outputs by default. 


In WordPress, an action is a hook activated at a specific moment while WordPress is operating and allows you to do a task. This may involve running a widget when WordPress is loading or when a work is published.


Before WordPress data is transmitted to the database or browser, you must use a WordPress filter to access and manage it. Modifying how excerpts are displayed or inserting custom code to the bottom of a blog post are two instances of filters.

Use of Hooks in WordPress

Hooks are used to automating a function’s execution. Using this technique, a theme/plugin can be altered, expanded, or limited.

Below is an example of a WordPress hook:

Hooks are frequently used to create application plugin components. Content management systems like WordPress, e-commerce sites and intranets use it.

Creating an Action Hook 

The WordPress plugin allows you to add an action hook by enabling its add action () method.

Hooks require a priority order to work correctly. In this scale, factors associated with each hook are ranked according to a numerical value from 1 to 999.

Lower priorities indicate earlier execution, whereas higher priorities indicate later performance.

Creating a Filter Hook

To make a filter hook, utilize the apply filters() function. A value can be modified, filtered, or replaced with a new value using the hook filter.

A filter hook (apply filter) is provided for filtering values using the related filter hook functions.

Furthermore, it can attach a hook filter with another function (add_filter).

 Here’s an example of a Filter Hook:

How to Unhook Actions and Filters in WordPress?

Remove action() and remove filter() functions can disable your WordPress code’s added actions and filter commands.

These codes are essentially a technique to filter out or exclude particular behaviors. By doing this, you can alter plugins that contain too many unnecessary hooks, potentially affecting the optimization of your site.

However, working with someone else’s plugins or themes is familiar with WordPress. If you remove the incorrect lines, you risk committing a deadly mistake.

Here’s an example of remove_action():
