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', $bc);
}
}
?>
Newbie Question
Eric,
I am a newbie, so pardon the dumb question, but ...where is it exactly that I need to put this function?
Thanks
template.php
Pardon me for not being more specific. You can add this function to your theme's template.php file. You'll have to replace "MYTHEME" in "MYTHEME_preprocess_page(&$variables)" with the name of your theme.
Regards,
Eric
