Yoast Breadcrumbs (SEO) and Events Manager fix

Here is a bit of code I used to get around Events Manager’s way of doing single events so the plugin will work with Yoast SEO’s breadcrumb function. It is not 100% foolproof but it works well enough for what I needed. I use it in header.php of my theme.

<?php
    //check if breadcrumbs and events manager functions exist
    if (function_exists('yoast_breadcrumb') && !is_front_page()) : ?>
    <div id="breadcrumb_wrapper" class="clearfix">
      <?php
          // set your before and after tags for breadcrumbs
          $bc_start = '<nav id="breadcrumbs"><div>';
          $bc_end   = '</div></nav>';

          // if is one of your pages that have events manager
          if ( ( is_page('Events') || is_page('Past Events') ) && function_exists( 'em_init' ) ) {
              // events calendar class
              global $EM_Event;   

              // get yoast options from database which can be set in yoast internal links settings page
              $opt = get_option("wpseo_internallinks");
              $bc_sep = $opt['breadcrumbs-sep'];
              $bc_home = $opt['breadcrumbs-home'];                                      

              if ( em_is_event_page() ) { // single event conditional
                $this_page = '<a href="'.site_url().'">'.$bc_home.'</a> '.$bc_sep.' <a href="'.get_permalink().'">'.get_the_title().'</a> '.$bc_sep.' <strong>'.$EM_Event->output('#_NAME').'</strong>';
                echo $bc_start.$this_page.$bc_end;
              } else {  // multi events list conditional
                  echo $bc_start.'<a href="'.site_url().'">'.$bc_home.'</a> '.$bc_sep.' <strong>'.get_the_title().'</a></strong>'.$bc_end;
              }
          } else { // do yoast bc function
              yoast_breadcrumb( $bc_start, $bc_end );
          }
      ?>
    </div>
<?php endif; ?>
