Das Folgende ist ein WordPress-Breadcrumb-Navigationscode, der von der WordPressTutorial-Kolumne geteilt wird. Ich hoffe, dass er Freunden, die ihn benötigen, hilfreich sein wird!
Drucken Sie einen Teil des WordPress-Breadcrumb-Navigationscodes erneut aus und teilen Sie ihn, der benutzerdefinierte Beitragstypen und benutzerdefinierte Kategorien unterstützt. Es scheint jedoch schade, dass die Hierarchie der übergeordneten und untergeordneten Kategorien nicht auf der Kategoriearchivseite angezeigt werden kann.
Fügen Sie den Code zur aktuellen Theme-Funktionsvorlage „functions.php“ hinzu:

Fügen Sie den aufrufenden Code an der entsprechenden Stelle der Theme-Vorlage ein, z. B. header.php:
<?php if (function_exists('tsh_wp_custom_breadcrumbs')) tsh_wp_custom_breadcrumbs(); ?>
Unterstützender Stil:
#tsh_breadcrumbs .separator{ font-size:20px; color:#ccc; font-weight:100; } #tsh_breadcrumbs{ overflow:hidden; text-align: center; list-style:none; margin:11px 0; } #tsh_breadcrumbs li{ margin-right:14px; display:inline-block; vertical-align:middle; }
