They help to customize WordPress without changing core files. Actions are helpful for maintaining website stability.
Some actions are used often in WordPress. For example, init runs when WordPress starts. wp_head adds code to the head section. wp_footer adds code to the footer. These actions help in adding scripts and styles. They ensure your site looks and works well.
Developers can create their own actions. This allows for more control. First, define the action using do_action. Then, attach a function using add_action. This function will run when the action is called. It makes WordPress flexible and powerful for all users.
Filters In WordPress
Filters in WordPress change data before it is shown on the site. They modify content like text and images. Filters help in making the site look how you want. They are like little helpers that tweak things.
