Category breadcrumb for a post

  • Hi,

    I am trying to create a simple breadcrumb of all the categories the post belongs to.

    At most, they are 2 levels deep i.e.

    Parent >> Child

    Otherwise, in other cases, is just the parent category. So, never more than two categories assigned to a post – Parent, Child or Category -> Subcategory.

    Using the following code, it works, but the problem is it does not always show the expected result:

    Parent >> Child

    BUT:

    Child >> Parent

    If the name of the subcategory is alphabetically before the parent category.

    if ( is_single() ) {
$separator = ' &raquo ';
$postID = $post->ID;
$catlink = get_the_category_list($separator,'multiple', $postID);

		//find >> in the string $catlink
		 $exists = strpos($catlink, $separator);

		if ($exists === false) {
    		$catlink = $catlink . $separator;
		}
		else
		{
   		 	$catlink = strstr($catlink, $separator);
			$catlink = ltrim($catlink, $separator);
		} 

	$breadcrumb = '<div class="breadcrumb"><div class="breadcrumb-trail">' . $catlink .'<span class="trail-end"></span></div></div>';
}

    Can someone please help me get the right code/functions to get the correct result?

    Your help is much appreciated.

    Regards,
    Indy
