This code snippet will show you how to search through the breadcrumbs and remove a particular item. Since I added this code to my theme in a preprocess_page function, I had to recreate $variables['breadcrumb']. NOTE: If I had chose to add this code to a module instead, I could have simply used the drupal_get_breadcrumb() and drupal_set_breadcrumb functions.
<?php
function MYTHEME_preprocess_page(&$variables) {
// in this example, I'm checking to see if icon_users.png exists in the breadcrumbs
if (stripos($variables['breadcrumb'],'icon_users.png')) {
// get the current breadcrumbs
$bc = drupal_get_breadcrumb();
// loop through the breadcrumbs
foreach ($bc as $k => $v) {
// check for a condition and remove as necessary
if (stripos($v,'icon_users.png')) unset($bc[$k]);
}
// recreate the breadcrumbs using the theme_breadcrumb function
$variables['breadcrumb'] = theme('breadcrumb', $bc);
}
}
?>
