Issue with Multiple Taxonomy Hierarchy and Breadcrumbs

Maybe try the http://drupal.org/project/node_breadcrumb or http://drupal.org/project/custom_breadcrumbs modules.

Please tell me who has solved this problem, how did you do it? I have same problem

Use the following in your template.php
For more info click here

function phptemplate_breadcrumb($breadcrumb) {
$uri_request_id = $_SERVER['REQUEST_URI'];
$urlexplode = explode("?", $uri_request_id);
$url = explode("/",$urlexplode[0]);
$args = count($url);

$output = " home";
$path = '';
$replace = array('_','-','+','%20');

// If there is more than one directory or page after home print it
if(isset($url[1]) && $args > 1){
for($x = 1; $x < $args; $x++) {
$text = htmlspecialchars(str_replace($replace,' ',$url[$x]));
if($x < ($args-1)) {
$path .= '/' . urlencode($url[$x]);
$output .= " > " . $text . "";
} else {
$output .= " > " . $text;
}
}
}
return '

';

}

I must say I'm a little surprised that this is still an issue in Drupal, one would have well and truly thought that by now breadcrumbs would follow the users navigation and not just default to a single path to a product that exists in multiple categories, anyway here's a fix, it's no work of art however it does seem to work.

Just put this at the top of your theme_breadcrumb

function mytheme_breadcrumb($vars) {
  
	//if the same product display (or any node) had the multiple taxonomy terms, the breadcrumb was not displaying as expected. Only one path seemed to be available to each node.
	//Setting session variables below to store breadcrumb values according to user navigation which will be displayed on nodes (of type product)
	if(isset($_SESSION['PREVIOUS_PAGE_TAXONOMY_BREADCRUMB'])){ //previous page was taxonomy (category)		
		//check if this page is a product
		if(arg(0) == 'node'){
			$node = node_load(arg(1));
			if($node->type == 'product'){
				//the current page is a product, the previous page was a category, so setting the breadcrumb to be the same as the last page
				$vars = $_SESSION['PREVIOUS_PAGE_TAXONOMY_BREADCRUMB'];
			}
			else{
				//unset the bredcrumb session variable here, we don't need it the whole session, here we are on a page that is not a product display or taxonomy page so it's not needed
				unset($_SESSION['PREVIOUS_PAGE_TAXONOMY_BREADCRUMB']);
			}
		}
	}
	
	if(arg(0) == 'taxonomy' && arg(1) == 'term'){
		
		//on a taxonomy page so assigning the breadcrumb to a session variable to it can be rendered based on user navigation when
		//we reach the product display
		
		$parts = count($vars['breadcrumb']);
		$current_path = '<a href="'. request_uri() .'">' . drupal_get_title() . '</a>';
		$bc = $vars;
		$bc['breadcrumb'][$parts] = $current_path;
		$_SESSION['PREVIOUS_PAGE_TAXONOMY_BREADCRUMB']  = $bc;
	}
	else{
		//not unsetting the session var because it would stuff the breadcrumb if the page was refreshed or a form was submitted, etc.
		//unset($_SESSION['PREVIOUS_PAGE_TAXONOMY_BREADCRUMB']);
	}

	
      /** now add your normal theme_breadcrumb code here **/
