Hi I have created a link for my breadcrumbs to show up in but for some reason the php code is not showing them up in the link is there away that could get them to show up in a class="breadcrumbs"


Code:
/**
 * Class Breadcrumb for CodeIgniter
 */
class Breadcrumb
{
  public $link_type = ''; // must have spaces around it
  public $breadcrumb = array();
  public $output = '<div class="breadcrumb">';

  /**
   * completely remove all previous generation data
   *
   * @return bool
   */
  public function clear()
  {
    // clear the breadcrumb library to start again
    $props = array('breadcrumb', 'output');

    // loop through
    foreach ($props as $val)
    {
      // clear
      $this->$val = null;
    }

    // completed
    return true;
  }

  /**
   * add a "crumb" - new link
   *
   * @param string $title displayed name of the link
   * @param bool $url place to go to
   * @return bool
   */
  public function add_crumb($title, $url = false)
  {
    // pass into breadcrumb array
    $this->breadcrumb[] =
      array(
      'title' => $title,
      'url' => $url
      );

    // completed
    return true;
  }

  /**
   * the delimiter between links
   *
   * @param string $new_link delimiter value
   * @return bool
   */
  public function change_link($new_link)
  {
    // change
    $this->link_type = ' ' . $new_link . ' '; // the spaces are added for visual reasons

    // completed
    return true;
  }

  /**
   * render an output
   *
   * @return string
   */
  public function output()
  {
    // define local counter
    $counter = 0;

    // loop through breadcrumbs
    foreach ($this->breadcrumb as $val)
    {
      // do we need to add a link?
      if ($counter > 0)
      {
        // we do
        $this->output .= $this->link_type;
      }

      // are we using a hyperlink?
      if ($val['url'])
      {
        // add href tag
        $this->output .= '<a href="' . $val['url'] . '">' . $val['title'] . '</a>';
      }
      else
      {
        // don't use hyperlinks
        $this->output .= $val['title'];
      }

      // increment counter
      $counter++;
    }

    // return
    return $this->output;
  }
}
