Hola,<br><br>Encontré el siguiente código:<br><pre>&lt;?php<br>/*<br> * quick and dirty breadcrumb menu<br> * initially designed for wordpress<br> */<br>function CPbreadcrumbs() {<br>    $CPtheFullUrl = $_SERVER[&quot;REQUEST_URI&quot;];
<br><br>    $CPurlArray=explode(&quot;/&quot;,$CPtheFullUrl);<br>    echo &#39;&lt;a href=&quot;/&quot;&gt;Home&lt;/a&gt;&#39;;<br>    while (list($CPj,$CPtext) = each($CPurlArray)) {<br>        $CPdir=&#39;&#39;;<br>        if ($CPj &gt; 1) {
<br><br>            $CPi=1;<br>            while ($CPi &lt; $CPj) {<br>                $CPdir .= &#39;/&#39; . $CPurlArray[$CPi];<br>                $CPtext = $CPurlArray[$CPi];<br>                $CPi++;<br>            }
<br>
            if($CPj &lt; count($CPurlArray)-1) echo &#39; &amp;raquo; &lt;a href=&quot;&#39;.$CPdir.&#39;&quot;&gt;&#39; . str_replace(&quot;-&quot;, &quot; &quot;, $CPtext) . &#39;&lt;/a&gt;&#39;;<br>        }<br>    }<br>

    /*echo wp_title();*/<br>}<br>CPbreadcrumbs();<br>?&gt;</pre>Y me funciona bien. Se puede ir adaptando con substr() o substr_replace().<br><br>Para más detalles, la página del creador es ésta: <a href="http://chrispoole.com/scripts/wordpress-php/wordpress-breadcrumbs/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
