Modification des fonctions WP_LIST_AUTHORS pour afficher tous les utilisateurs dans une grille (et une pagination)

Le titre dit tout.

Je prends WP_LIST_AUTHOR et le modifie pour créer plus d'un répertoire de membres qu'une liste d'auteurs tout en conservant intactes les options d'origine (et je vais en ajouter d'autres ultérieurement). Ma première tâche a été d’intégrer la pagination, ce que j’ai réussi à faire (code ci-dessous) [même si ce n’est pas encore très joli].

Je souhaite maintenant que cette information soit intégrée dans des tableaux (probablement 15 résultats par page, dans une grille de 3x5. Cellule de cellule en rangée, cellule de cellule en rangée, etc.). Je ne suis pas vraiment sûr de la meilleure façon de faire cela, ou si cela peut même être fait avec la façon dont le code est construit, tout conseil ou toute ressource liée serait grandement apprécié! Je suis vraiment en train de pirater des choses ensemble;) Notez également; le site utilise le plugin s2member et tout code ne devra pas être dérangé par cette fonctionnalité.

Votre extrait est un peu trop verbeux à suivre (et il est tard ici), donc c'est plutôt une prise alternative. Je pense que falsifier wp_list_author() pourrait être excessif ici. Il serait plus élégant d’accrocher à la recherche d’utilisateur et de découper avec précision la portion d’auteurs dont vous avez besoin.

Voici un exemple de code que j'ai créé:

add_action('pre_user_query','offset_authors');

$authors_per_page = 1;
$current_page = absint(get_query_var('page'));

function offset_authors( $query ) {

    global $current_page, $authors_per_page;

    $offset = empty($current_page) ? 0 : ($current_page - 1) * $authors_per_page;    
    $query->query_limit = "LIMIT {$offset},{$authors_per_page}";
}

wp_list_authors();

Vérifiez également paginate_links() la fonction de construction de la pagination.
