Fil d'Ariane avec type de message personnalisé sans plugin
J'ai utilisé la fonction suivante pour la chapelure sur chaque site à ce jour, mais le site d'aujourd'hui a 3 types de publication personnalisés et le client souhaite que la chapelure fonctionne, par exemple. au lieu de "maison/vins/naire blanco", nous obtenons simplement "maison// naire blanco".
function the_breadcrumb() {
echo '<ol class="breadcrumb" itemprop="breadcrumb">';
if (!is_home()) {
echo '<li><a href="';
echo get_option('home');
echo '">';
echo 'Home';
echo '</a></li>';
if (is_category() || is_single() || is_post_type()) {
echo '<li>';
the_category(' </li><li> ');
echo get_post_type(' </li><li> ');
if (is_single()) {
echo '</li><li>';
the_title();
echo '</li>';
}
} elseif (is_page()) {
if($post->post_parent){
$anc = get_post_ancestors( $post->ID );
foreach ( $anc as $ancestor ) {
$output = $output . '<li><a href="'.get_permalink($ancestor).'" title="'.get_the_title($ancestor).'">'.get_the_title($ancestor).'</a></li> ';
}
echo $output;
echo '<strong title="'.$title.'"> '.$title.'</strong>';
} else {
echo '<li><a class="active" href="';
echo the_permalink();
echo '">';
echo the_title();
echo '</a></li>';
}
}
}
elseif (is_tag()) {single_tag_title();}
elseif (is_day()) {echo"<li>Archive for "; the_time('F jS, Y'); echo'</li>';}
elseif (is_month()) {echo"<li>Archive for "; the_time('F, Y'); echo'</li>';}
elseif (is_year()) {echo"<li>Archive for "; the_time('Y'); echo'</li>';}
elseif (is_author()) {echo"<li>Author Archive"; echo'</li>';}
elseif (isset($_GET['paged']) && !empty($_GET['paged'])) {echo "<li>Blog Archives"; echo'</li>';}
elseif (is_search()) {echo"<li>Search Results"; echo'</li>';}
echo '</ol>';
}
Comme vous pouvez le voir dans le code, j'ai essayé d'ajouter || is_post_type() après is_category() || is_single() avec un echo get_post_type() mais cela n'a rien fait.
J'apprécierais quelques conseils s'il vous plaît.
Merci
Le problème avec la plupart des fonctions de navigation est qu'il repose sur l'objet $post sur toutes les pages. Non seulement le $post global est totalement peu fiable ( voir mon post ici), il pourrait même ne pas contenir les données dont nous avons besoin, même si le $post global n'est pas compromis
Le $post global sur les pages d'archive ( qui comprend la catégorie, le tag, la date, le terme de taxonomie, l'auteur et l'archive de type de publication personnalisée ) contient la première publication de la boucle avant la boucle. Il n'est pas toujours vrai que le premier message provient de l'archive sélectionnée ( la page d'archive sur laquelle vous vous trouvez ), ce qui signifie que les informations que vous recherchez sont peut-être incorrectes, même si le $post global n'est pas compromis. . Les conditions dans lesquelles le premier message peut ne pas provenir de l'archive sélectionnée sont les messages injectés via des étiquettes personnalisées et le filtre the_posts.
J'ai récemment réécrit une de mes très anciennes fonctions de fil d'Ariane qui utilise l'objet $GLOBALS['wp_the_query'] et l'objet interrogé enregistré dans le $GLOBALS['wp_the_query'] global. Ainsi, nous disposons d'un fil d'Ariane fiable à 99,999% qui ne repose pas sur le $post global ni sur les données compromises.
Voici la fonction: ( Nécessite PHP 5.4+. N'hésitez pas non plus à modifier au besoin )

Vous pouvez simplement l'appeler comme suit
echo get_hansel_and_gretel_breadcrumbs();
si nécessaire
Cette fonction de fil d'Ariane prend également en charge les types de messages personnalisés
Excellent! Travaille le code de réponse acceptée (de Pieter Goosen).
Note: Je viens d'ajouter une petite tâche de plus. Effectuez un contrôle de validation de cette fonction avant d'appeler il, de cette façon:
<?php
if(function_exists('get_hansel_and_gretel_breadcrumbs')):
echo get_hansel_and_gretel_breadcrumbs();
endif;
?>
De plus, j’ai sauvegardé cette fonction dans un fichier nommé breadcrumbs.php dans le dossier racine du projet et l’a inclus dans functions.php file en utilisant include_once('breadcrumbs.php'); pour être plus organisé.
