In WordPress there are two types of hooks – Action Hooks and Filter Hooks.
1. Action Hooks:
Action hooks allow you to add additional code to the WordPress core or theme so that you can achieve some new functionality or new level of customizations.

Create a function in your theme’s functions.php file and hook it on using the add_action() function.


add_action( 'wp_head', 'aviance_actionhook_demo' );
function aviance_actionhook_demo () {
echo '<meta name="keywords" content="wordpress action hooks and filter hooks introduction" />' . "

} // End aviance_actionhook_demo()


2. Filter Hooks:

Filter hooks are used to manipulate output. An example of this would be to add a line or text to the end of the content of each of your blog posts. Filter hooks can also be used for truncating text, changing formatting of the content.


add_filter( ‘wp_title’, ‘Add_sitename_to_wptitle’, 10, 2 );
Add_sitename_to_wptitle( $title, $sep ) {
/* Get website name. */
$name = get_bloginfo( ‘name’ );
/* Append website name to $title. */
$title .= $sep . ‘ ‘ . $name;
/* Return the title. */
return $title;
