WordPress – Custom Taxonomy Breadcrumb

function show_breadcrumb($name,$type){
	$list = "";		
	$home = get_bloginfo("home");
	if ($type &amp;&amp; $name){
		$ans = get_term_by('name', $name, $type);		 
		$parentID=$ans-&gt;parent;
		while ($parentID &gt; 0){
			$parent = get_term_by('id', $parentID, $type);	
			$url = $home."/".$type."/".$parent-&gt;slug;
			$list = "&lt;li&gt;&lt;a href='".$url."'&gt;".$parent-&gt;name."&lt;/a&gt;&lt;/li&gt;".$list;
			$parentID = $parent-&gt;parent;
		}
		$url = $home."/".$type."/".$ans-&gt;slug;
		$list = $list."&lt;li&gt;".$ans-&gt;name."&lt;/li&gt;";
	}	

	if ($list) echo "&lt;ul&gt;&lt;li&gt;&lt;a href='$home'&gt;Home&lt;/a&gt;&lt;/li&gt;".$list."&lt;/ul&gt;";	
}

function show_breadcrumb($name,$type){

$list = "";

$home = get_bloginfo("home");

if ($type && $name){

$ans = get_term_by('name', $name, $type);

$parentID=$ans->parent;

while ($parentID > 0){

$parent = get_term_by('id', $parentID, $type);

$url = $home."/".$type."/".$parent->slug;

$list = "<li><a href='".$url."'>".$parent->name."</a></li>".$list;

$parentID = $parent->parent;

}

$url = $home."/".$type."/".$ans->slug;

$list = $list."<li>".$ans->name."</li>";

}

if ($list) echo "<ul><li><a href='$home'>Home</a></li>".$list."</ul>";

}

then use following code to output breadcrumb in UL format.

// Format
&lt;?php show_breadcrumb("term-name","taxonomy"); ?&gt; 

// To list breadcrumbs of "Catalog" taxonomy.
&lt;?php show_breadcrumb(single_tag_title("", false),"catalog"); ?&gt;

// Format

<?php show_breadcrumb("term-name","taxonomy"); ?>

// To list breadcrumbs of "Catalog" taxonomy.

<?php show_breadcrumb(single_tag_title("", false),"catalog"); ?>
