Agaric would like breadcrumbs in Drupal to just work, but barring that until book navigation becomes general navigation in Drupal 6, we'd just like control...
Custom Breadcrumbs module

From the PHP snippet section...
Breadcrumbs including title
Display full Breadcrumb in node

Rejected approach... reaccepted approach...

Test code first and then the result:

drupal_set_message('arg(1): '. arg(1));
drupal_set_message('arg(2): '. arg(2));
drupal_set_message('arg(3): '. arg(3));
?>
* arg(0): node
* arg(1): 4
* arg(2):
* arg(3):

<?php
drupal_set_message('<pre>'.print_r($breadcrumb,TRUE).'</pre>');
?>
Array
(

<?php

Preliminary version: structure for catching specific pages, and a rudimentary catch-all for pages with menu associations.
<?php
function phptemplate_breadcrumb($breadcrumb) {
// uncomment below to see what's available
/*
drupal_set_message('arg(0): '. arg(0));
drupal_set_message('arg(1): '. arg(1));
drupal_set_message('arg(2): '. arg(2));
drupal_set_message('arg(3): '. arg(3));
drupal_set_message('<pre>'.print_r($breadcrumb,TRUE).'</pre>');
*/
if (arg(0) == 'showyoursupport') {
}
/*
elseif (arg(0) == 'view' && arg(1) == 'membervideos') {
}
elseif (arg(0) == 'node' && arg(1) == 4) {
// Catalyst for a Cure
// this is actually done pretty well by the below
}
*/
elseif (count($breadcrumb) == 1) { // let's try to help it
$menu = _menu_get_active_trail();
array_pop($menu); // get rid of the last value, which is the current page
unset($menu[0]); // first one is usually no good either (Primary Links)
foreach ($menu as $mid) {
$item = menu_get_item($mid);
$breadcrumb[] = l($item['title'], $item['path']);
}
}
if (!empty($breadcrumb)) {
return '<div class="breadcrumb">'. implode(' » ', $breadcrumb) .'</div>';
}
