Comment réparer Warning: call_user_func_array ()?

Question

J'ai modifié mon thème metabox.php pour l'adapter à mes besoins, et j'ai eu cet eror

Avertissement de citation de bloc: call_user_func_array () s'attend à ce que le paramètre 1 soit un rappel valide, la fonction 'mytheme_add_box' est introuvable ou un nom de fonction non valide dans E:\xampp\htdocs\wordpress\wp-includes\plugin.php à la ligne 406 Blockquote

Comment puis-je résoudre ce problème?

Answer 1

Je ne suis pas sûr que cela aidera, mais après avoir traité exactement le même message d'erreur au cours des 2 derniers jours, j'ai finalement compris ce qui se passait. Il s'agissait simplement d'essayer d'appeler la fonction avant que le système ne sache qu'elle existait.

Dans mon cas, j'avais écrit la fonction dans un répertoire distinct - non accessible publiquement - et tenté d'appeler cette fonction dans mon fichier functions.php avant même d'inclure le fichier qui contenait la fonction.

Dans mon fichier custom_funcs.php se trouvait cette fonction:

function my_custom_funk($url, $path = '', $plugin = '') {
    $Host = get_this_cust_url( $url );
    $url = str_replace( parse_url( WP_PLUGIN_URL, PHP_URL_Host ), $Host, $url );
    return $url;
}

À l'intérieur de mon fichier functions.php, je faisais ceci:

// get the funk
add_filter( 'plugins_url', 'my_custom_funk' );

// Load Custom Functions
include( '/my/non-public/path/custom_funcs.php' );

Une fois que j'ai changé leur ordre à cette ...

// Load Custom Functions
include( '/my/non-public/path/custom_funcs.php' );

// get the funk
add_filter( 'plugins_url', 'my_custom_funk' );

... l'erreur s'est complètement arrêtée.

J'espère que cela aidera et sauvera quelqu'un deux jours de débogage.

Enfin, les messages lire ici sont ce qui me conduit à faire le changement.
