Flexy Breadcrumb

Flexy Breadcrumb is a super light weight plugin that is easy to navigate through current page hierarchy.

Marin Atanasov

<p>Provides the theme and plugin developers an easy way to build and implement highly customizable breadcrumb functionality, specifically tailored to their needs.<br />
Supports a lot of filters and hooks, and is written in OOP style, giving developers full control over the breadcrumb trail items and appearance.<br />
This plugin can also be embedded in themes, instead of installing it as a WordPress plugin.</p>
<h3>Configuration</h3>
<p>The most basic way to insert Carbon Breadcrumbs in your theme code is:</p>
<pre><code><?php Carbon_Breadcrumb_Trail::output(); ?>
</code></pre>
<p>If you want to specify various breadcrumb rendering options, you can specify them in an array, like this:</p>
<pre><code><?php
Carbon_Breadcrumb_Trail::output(array(
    'glue' => ' &gt; ', // glue between breadcrumb items
    'link_before' => '',
    'link_after' => '',
    'wrapper_before' => '',
    'wrapper_after' => '',
    'title_before' => '',
    'title_after' => '',
    'min_items' => 2,
    'last_item_link' => true,
    'display_home_item' => true,
    'home_item_title' => __('Home', 'carbon_breadcrumbs'),
    'renderer' => 'Carbon_Breadcrumb_Trail_Renderer',
));
?>
</code></pre>

Carbon Breadcrumbs

This remains the best breadcrumbs plugin I've used. In addition to its rich customization options, it provides developers with various easy ways to extend it.



The best breadcrumbs plugin I've used

This plugin has saved me quite some time.
Thanks to the numerous filters, you can adjust everything.
Respect <3



Very customizable


GREAT plugin, fantastic codebase: super clean & TESTED?! FTW!

Only downside is no schematagging out of the box :/. This is a pivotal SEO feature and I think this would greatly boost interest in your plugin.

Info: https://developers.google.com/search/docs/data-types/breadcrumbs#guidelines

Result should look like:

<ol itemscope itemtype="http://schema.org/BreadcrumbList">
  <li itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem">
    <a itemscope itemtype="http://schema.org/WebPage"
       itemprop="item" href="link.html">
        <span itemprop="name">Crumb 1</span>
    </a>
    <meta itemprop="position" content="1" />
/
  </li>
  <li itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem">
    <a itemscope itemtype="http://schema.org/WebPage"
       itemprop="item" href="link2.html">
        <span itemprop="name">Crumb 2</span>
    </a>
    <meta itemprop="position" content="2" />
  </li>
</ol>



Here's how I've shimmed it in:


<?php
  $breadcrumbs = new Carbon_Breadcrumb_Trail(array(
    'glue' => ' / ',
    'link_before' => '<li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">',
    'link_after' => '</li>',
    'wrapper_before' => '<ol class="breadcrumbs" itemscope itemtype="http://schema.org/BreadcrumbList">',
    'wrapper_after' => '</ol>',
    'title_before' => '<span itemprop="name">',
    'title_after' => '</span>',
  ));

  $breadcrumbs->setup();
  echo $breadcrumbs->render(true); // WP_KSES strips itemprop, itemscope, etc, so bypassing!!!

  add_filter('carbon_breadcrumbs_item_attributes', _'breadcrumb_schematags', 10, 2);
  function breadcrumb_schematags($attributes, $item) {
    if (!is_array($attributes)) $attributes = array();
    $attributes['itemscope'] = null;
    $attributes['itemtype'] = 'http://schema.org/WebPage';
    $attributes['itemprop'] = 'item';
    return $attributes;
  }
  add_filter('carbon_breadcrumbs_item_output', 'breadcrumb_item_position', 10, 5);
  function breadcrumb_item_position($item_output, $item, $trail, $trail_renderer, $index){
    // Add Position
    $n = strrpos($item_output, '</li>');
    $item_output = substr($item_output, 0, $n)  . '<meta itemprop="position" content="'. $index .'" />' . substr($item_output, $n);
    return $item_output;
  }



Really wonderful, well-thought code. wish there were schematags

A basic WordPress plugin for breadcrumbs with advanced capabilities for extending.
