Add attributes to Drupal breadcrumb links.
If you for any reason would like to add attributes to your breadcrumb links, this is how i did it; instead of
print $breadcrumb;
i did
print str_replace('">', '" target="_top">', $breadcrumb);
I needed this because i created a template with frames for external links. The top of the frame uses the standard "header" region, the bottom uses an external link. This snippet makes sure that when i click on a breadcrumb link, it will open in the "_top". You could use this to add any odd attribute though. I welcome cleaner methods, this worked for me though. It took me a while to figure this out so i thought i'd share.
Perhaps a Better Way
more "clean" way is to override theme function in template.php, insted of making breadcrumb changes in page.tpl.php
example: (template.php)
function mytheme_breadcrumb($breadcrumb) {
$sep = ' > ';
if (count($breadcrumb) > 0) {
return implode($breadcrumb, $sep) . $sep;
}
else {
return t("Home");
}
}or other example: (template.php)
function phptemplate_breadcrumb($breadcrumb) {
if (!empty($breadcrumb)) {
return '<div class="breadcrumb">'. implode(' » ', $breadcrumb) .'</div>';
}
