-The Adventure of the Copper Beeches

So let's gather some real data from an install with no plugins and the TwentyTwelve theme activated with only a single Text widget.

For the home page the following do_action calls are made in the following order:

muplugins_loaded
registered_taxonomy
registered_taxonomy
registered_taxonomy
registered_taxonomy
registered_taxonomy
registered_post_type
registered_post_type
registered_post_type
registered_post_type

setup_theme
unload_textdomain
load_textdomain
after_setup_theme
load_textdomain
load_textdomain
auth_cookie_malformed

dynamic_sidebar
dynamic_sidebar_after
get_footer

wp_footer
wp_print_footer_scripts
wp_before_admin_bar_render
wp_after_admin_bar_render
shutdown

If you want to check the order of actions and how many times each one is fired, then you can use for example:

add_action( 'shutdown', function(){
    print_r( $GLOBALS['wp_actions'] ); 
});

or this prettified version:

add_action( 'shutdown', function(){
    foreach( $GLOBALS['wp_actions'] as $action => $count )
        printf( '%s (%d) <br/>' . PHP_EOL, $action, $count );

});

to get the following list:

muplugins_loaded (1) 
registered_taxonomy (10) 
registered_post_type (10) 
plugins_loaded (1) 
sanitize_comment_cookies (1) 
setup_theme (1)

Solutiontrouvée!

Merci @birgire pour cettebelle réponse. J'ajouterai à cela,muplugins_loadedn'estparfoispas déclenché,doncj'utiliserai plugins_loaded commepremier hook (mais à cemoment -l'autorisationn'estpasencoreterminée. Si vous souhaitez vérifier l'autorisation de l'utilisateur,initest lepremierpour cela) ...

p.s.ilexiste d'excellentsplugins:

1) Query Monitor - Vouspouveztout voir ce qui sepasse lors du chargement de lapage,c'est-à-dire la durée de chaquefonctionexécutéeet bienplusencore (voirtoutes les captures d'écran sur lapage duplugin):

2) WP-DEBUG-BAR + < strong> WP-DEBUG-SLOW-ACTIONS :
a) la liste d'exécution des hooks de débogage ( actions ) sur votre site.
b) Voir la durée de chaque action (pas defonction):

Found Solution!

Thanks @birgire for nice answer. I will add to that, muplugins_loaded sometimes is not fired, so I will use plugins_loaded as the most first hook (but at that time, user-authorization is not done yet. If you want to check user's authorization, then init is the earliest for that)...

p.s. there exist excellent plugins:

1) Query Monitor - You can see everything what happens on the page-load, i.e. duration of each executed function and much more(view all screenshots on plugin page):

2) WP-DEBUG-BAR + WP-DEBUG-SLOW-ACTIONS:
a) debug hooks(actions) run list on your site.
b) See duration of each action (not function):

Iln'y apas deux demandesexactementidentiques.Unmoyen rapide (maistrèsprécis) de savoir ce qui sepasseest d'ajouter temporairement une ligne au début de lafonction do_action dans wp-includes/plugin.php quienregistre la $tag,parexemple:

 if (isset($some_get_or_post_trigger_var)) file_put_contents(ABSPATH . 'action.log', "$tag\n", FILE_APPEND);
 

No two requests are exactly the same. A quick and dirty (but very accurate) way to find out what's going on is to temporarily add a line to the start of the do_action function in wp-includes/plugin.php which logs the $tag, e.g.:

if (isset($some_get_or_post_trigger_var)) file_put_contents(ABSPATH . 'action.log', "$tag\n", FILE_APPEND);

La séquence debasepeut également êtretrouvée sur la documentation officielle:

The basic sequence can also be found on the official docs:

Ceciest similaire à la réponse de @birgire,mais celafournit unbon rapport quipeut être affichépourn'importe quelle URL dans un site WordPress. Vous devrez être connectéen tant qu'utilisateur deniveau Admin,puis ajouter ?wp-hooks à lafin d'une URL que vous souhaiteztester.

 /**

    // Only shown for Administrator level users when ?list-wp-hooks is added to the URL
    $trigger = isset( $_GET['wp-hooks'] ) && current_user_can( 'manage_options' );

This is similar to the @birgire's answer, but it provides a nice report that can be displayed for any URL in a WordPress site. You'll need to be logged-in as an Admin level user, then add ?wp-hooks onto the end of a URL you want to test.

/**
* WordPress Hooks Reference
*
* Dump all action and filter hooks at the bottom of any page
* by adding ?wp-hooks onto the end of the URL while logged-in
* as an Administrator level user.

function kevinlearynet_hooks_reference() {

    // Only shown for Administrator level users when ?list-wp-hooks is added to the URL
    $trigger = isset( $_GET['wp-hooks'] ) && current_user_can( 'manage_options' );
    if ( ! $trigger ) return;

    // Capture and sort filters and hooks
    $filters = array_keys( $GLOBALS['wp_filter'] );
    sort( $filters );
    $actions = array_keys( $GLOBALS['wp_actions'] );

    // Output rough template
    ob_start();
    ?>
    <section class="wp-hooks">
    <h1 class="wp-hooks__h1">WordPress Hooks Reference</h1>

    </section>
    <style>
    .wp-hooks {
        padding: 30px;
        margin: 30px;
        border-radius: 4px;
        background: white;
        font-size: 16px;
        line-height: 1.4;
        height: 50vh;
        min-height: 500px;
        overflow-y: scroll;
    }
    .wp-hooks__lists {
        display: flex;
    }
    .wp-hooks__col {
        flex: 1;
        width: 50%;
    }
    .wp-hooks__h1 {
        margin: 0 0 20px;
    }
    .wp-hooks__h2 {
        line-height: 1;
        font-size: 18px;
        margin: 0 0 10px;
    }
    .wp-hooks__hook {
        padding: 0;
        margin: 0;
    }
    </style>
    <?php
    ob_end_flush();
}
add_action( 'shutdown', 'kevinlearynet_hooks_reference' );

The output looks like this:

I wrote about this on my own, so here's the original source for reference. This includes a little more detail on decisions behind sorting and functionality.
