    Example

    – Create a link category named “Related Sites”
    – Create a few links, adding them to the “Related Sites” category

    You may use the following code in your templates to retrieve the links:

    $bookmarks = get_bookmarks( array(
    	'orderby'        => 'name',
    	'order'          => 'ASC',
    	'category_name'  => 'Related Sites'
    ) );
    
    // Loop through each bookmark and print formatted output
    foreach ( $bookmarks as $bookmark ) { 
        printf( '<a class="relatedlink" href="%1$s">%2$s</a><br />', esc_attr( $bookmark->link_url ), $bookmark->link_name );
    }
