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