Breadcrumb trail

  • For those wishing to use a non-plugin based breadcrumb trail, simply insert the following code in functions:

    function breadcrumb() {
	// Check if Permalinks are enabled

	$breadcrumb = array();

	// Get current post
	$current = $post->ID;

	// Check if current post has ancestors
	if($GLOBALS['post']->ancestors) {
		$ancestors = $GLOBALS['post']->ancestors;

		// Step through ancestors array to build breadcrumb
		foreach($ancestors as $i => $text)
		{
		$breadcrumb[$i] = '<a href="' . get_page_link($text) . '" title="' . attribute_escape(apply_filters('the_title', $text->post_title)) . '">'.get_the_title($text).'</a>';}
	}
	// Insert a link to home
	array_unshift($breadcrumb, '<a href="' . get_option('home') . '" alt="Home" title="Home">Home</a>');

	$breadcrumb[] .= '<a href="' . get_page_link($current->ID) . '" title="' . attribute_escape(apply_filters('the_title', $current->post_title)) . '">'.get_the_title($current).'</a>';

	// Display breacrumb with demarcator
	echo implode(' > ', $breadcrumb);
}

    I jumped the gun a little there. Here’s a more robust version:

    $breadcrumb = array();

	// Get current page
	global $wp_query;
	$current = $wp_query->post;

	// Check if current post has ancestors
	if($current->ancestors) {
		$ancestors = array_reverse($current->ancestors);

		// Step through ancestors array to build breadcrumb
		foreach($ancestors as $i => $text)
		{
			$breadcrumb[$i] = '<a href="' . get_page_link($text) . '" title="' . attribute_escape(apply_filters('the_title', $text->post_title)) . '">'.ucfirst(strtolower(get_the_title($text))).'</a>';
		}
	}

	// Insert a link to the current page
	$breadcrumb[] = '<a href="' . get_page_link($current->ID) . '" title="' . attribute_escape(apply_filters('the_title', $current->post_title)) . '">'.ucfirst(strtolower(get_the_title($current))).'</a>';

	// Insert a link to home
	array_unshift($breadcrumb, '<a href="' . get_option('home') . '" alt="Home" title="Home">Home</a>');

	// Display breacrumb with demarcator
	echo implode(' > ', $breadcrumb);
}
