分享一個(gè)WordPress面包屑導(dǎo)航代碼

3010

下面由WordPress教程欄目給大家分享一個(gè)wordpress面包屑導(dǎo)航代碼，希望對(duì)需要的朋友有所幫助！

轉(zhuǎn)載分享一段WordPress面包屑導(dǎo)航代碼，支持自定義帖子類型、自定義分類，但貌似在分類歸檔頁面不能顯示父子分類層級(jí)有點(diǎn)遺憾。

將代碼添加到當(dāng)前主題函數(shù)模板functions.php中：

將調(diào)用代碼放到主題模板適當(dāng)位置比如header.php中：

<?php  if (function_exists(&#39;tsh_wp_custom_breadcrumbs&#39;)) tsh_wp_custom_breadcrumbs(); ?>

配套樣式：

#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; }
