Fil d'Ariane montrant les Pages Parent et Enfant

Nous essayons de créer une fonction pour le fil d'Ariane qui affichera non seulement le chemin d'accès à la page en cours, mais également aux autres pages avec la même page parente.

Par exemple, sur example.com/parent1/child3, la chapelure indique Maison> Parent1> Enfant1> Enfant2> Enfant3> Enfant4 plutôt que simplement Accueil> Parent1> Enfant3.

Nous utilisons une version modifiée du script de chapelure de http://dimox.net/wordpress-breadcrumbs-without-a-plugin/:

Des idées? Nous apprécions vraiment cela.

Nick

je ne veux pas que cela retourne dans votre chapelure ... ce qui, par nature, est selon moi hiérarchique.

mais cela devrait vous donner une liste des pages qui ont le même parent que la page sur laquelle vous vous trouvez (c'est-à-dire ses frères et sœurs), bien que de manière totalement dénuée de style

global $post;

$args = array('child_of' => $post->post_parent, 'exclude'=> $post->ID);
if ($post->post_parent) $pages = get_pages($args);

if ($pages) foreach ($pages as $page): 
    echo $page->post_title .'<br/>';
endforeach;

si vous listez votre actuelle page, puis ses frères et sœurs, vous pouvez recréer par programmation ce que vous recherchez, je pense

edit 1: setup postdata afin que nous puissions utiliser get_permalink (), get_the_title () à l'intérieur d'un "loop", etc., au lieu de méthodes d'objet. get_permalink () obtient l'URL de l'élément en cours dans la boucle

global $post;

$args = array('child_of' => $post->post_parent, 'exclude'=> $post->ID);
if ($post->post_parent) $pages = get_pages($args);

if ($pages) :

//store the $temp variable
$temp = $post;

$siblings = '<ul>';

foreach ($pages as $post): setup_postdata($post); 

    $siblings .= '<li><a href="'.get_permalink().'">'.get_the_title().'</a></li>';
endforeach;

//restore the $post variable
$post = $temp;

$siblings .= '</ul>';

echo $siblings;

endif;

les arguments sont différents, mais http://codex.wordpress.org/Function_Reference/get_posts#Reset_after_Postlists_with_offset est la boucle foreach sur laquelle je travaille habituellement. get_posts, mais get_pages fonctionne de la même manière, sauf qu’il ne renvoie que des pages.
