Trailing Separators when using Zen based themes and Custom Breadcrumbs
While using the Custom Breadcrumbs module to implement breadcrumbs on Views pages for a client’s site, I encountered an issue where my breadcrumbs had an extra separator appended at the end of my breadcrumbs but only on the Views pages. This left me with breadcrumbs like:
“Home > People > Search > Results > “
instead of:
“Home > People > Search > Results”.
On my theme’s configuration, I have the “Append the content title to the end of the breadcrumb” option checked. Unchecking this option removes the trailing “>” but now all my other breadcrumbs lack the page’s title at the end of the breadcrumb.
I copied over Zen’s breadcrumb function to my template.php and made a few simple modifications. If you have a zen based theme and want to use Custom Breadcrumbs, try adding this function to your theme’s template.php. Remember to change the function name (zen_breadcrumb) to match your theme’s name (yourtheme_breadcrumb).
/**
* Return a themed breadcrumb trail.
*
* @param $breadcrumb
* An array containing the breadcrumb links.
* @return
* A string containing the breadcrumb output.
*/
function zen_breadcrumb($breadcrumb) {
// Determine if we are to display the breadcrumb.
$show_breadcrumb = theme_get_setting('zen_breadcrumb');
if ($show_breadcrumb == 'yes' || $show_breadcrumb == 'admin' && arg(0) == 'admin') {
// Optionally get rid of the homepage link.
$show_breadcrumb_home = theme_get_setting('zen_breadcrumb_home');
if (!$show_breadcrumb_home) {
array_shift($breadcrumb);
}
// Return the breadcrumb with separators.
if (!empty($breadcrumb)) {
$breadcrumb_separator = theme_get_setting('zen_breadcrumb_separator');
$trailing_separator = $title = '';
if (theme_get_setting('zen_breadcrumb_title')) {
$trailing_separator = $breadcrumb_separator;
$title = menu_get_active_title();
//Check for empty title and kill separator if necessary.
if($title == ''){
$trailing_separator = '';
}
}
elseif (theme_get_setting('zen_breadcrumb_trailing')) {
$trailing_separator = $breadcrumb_separator;
}
return '";
}
}
// Otherwise, return an empty string.
return '';
}
Even if a Views page has a menu entry and page title, it’s title is not returned by the menu_get_active_title() function. I’ve added a simple if/then statement that checks for a title and, if it’s empty, it sets the separator as an empty value, as well. I haven’t tested it but I think similar issues would arise with panels. This snippet should take care of those issues.
