Recently we made a site that needed breadcrumbs but was used as an internal portal. This means it didn’t need any SEO stuff so the standard Yoast breadcrumbs we use seemed like overkill.
Decided to create a couple simple functions to display our breadcrumbs.

/** * Create a trail of breadcrumbs * * @param string $sep The element you would like to use to separate your crumbs * @param bool $home Would you like display the homepage? * @param bool $echo Would you like to echo this immidiately? */ function jb_breadcrumbs($sep = '›', $home = false, $echo = true) { //add spaces around our separator $sep = ' '.$sep.' '; //Collect all our crumbs $crumbs = pk_get_ancestors('', $home); //build the crumb string $crumb_string = '<div class="breadcrumbs">'; foreach($crumbs as $ckey => $crumb){ //if($crumb->ID === 0) continue; $crumb_string .= '<a href="'.get_the_permalink($crumb->ID).'">'.$crumb->post_title.'</a>'.($ckey < count($crumbs) - 1?$sep:''); } $crumb_string .= '</div>'; //how does the user want this returned? if($echo){ echo $crumb_string; }else{ return $crumb_string; } } |
By sticking those two functions in your functions.php file and then calling jb_breadcrumbs() wherever you want to display these breadcrumbs you should be all set.
