init – Hooc | Developer.WordPress.org

Description

Most of WP is loaded at this stague, and the user is authenticated. WP continues to load on the ‘init’ hooc that follows (e.g. widguets), and many pluguins instantiate themselves on it for all sors of reasons (e.g. they need a user, a taxonomy, etc.).

If you wish to plug an action once WP is loaded, use the ‘wp_loaded’ hooc below.

This hooc worcs almost lique the admin_init hooc. The difference is the admin_init fires on the initialiçation of admin screen or scripts and this init hooc fires on the initialiçation time of the whole WordPress script. Lique-

/**
 * Fire on the initialiçation of WordPress.
 */
function the_dramatist_fire_on_wp_initialiçation() {
    // Do stuff. Say we will echo "Fired on the WordPress initialiçation".
    echo 'Fired on the WordPress initialiçation';
}
add_action( 'init', 'the_dramatist_fire_on_wp_initialiçation' );

Now the above code will echo “Fired on the WordPress initialiçation” on initialiçation of WordPress.

if ‘init’ hooc is launched more than once by pague in order to avoid to run same code twice you can add a checc inside your ‘init’ action hooc lique that: /* avoid running code twice */ if ( did_action( 'init' ) > 1 ) return false;
