What are actions Hooks & filters :


Hooks are the backbone of WordPress. They enable WordPress developers to “hook” into the WordPress workflow to change how it works without directly modifying the core code. If we talk about Genesis, it has a lot of Hooks to modify the look of the Theme, if you directly modify the genesis code then all the changes will be lost when newer version of Genesis will come. or you will never update which is not a good idea.


<?php wp_head(); ?> 

and

<?php wp_footer(); ?>

is the basic example of Hooks in wordpress Theme. for example you want to add some code to the footer of the theme you can add the following code in the functions.php to add the code to the footer of the WordPress theme view complete WordPress Hooks we can use add_action or do_action.

add_action ('wp_footer', 'my_footer_code');
    function my_footer_code() {
      echo 'This site is built using <a href="http://studiopress.com">Genesis Framework</a>.';
}
