Question

Well I have this code –

function breadcrumbs($separator = ' » ', $home = 'Home') {
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");
    foreach ($path AS $x => $crumb) {
        $title = ucwords(str_replace(Array('.php', '_', '-'), Array('', ' ', ' '), $crumb));
        $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";  
    }
    return implode($separator, $breadcrumbs);
}

And lets say I am at the page url of:

http://www.mysite.com/forums/general/log-book

this function displays the breadcrumb correctly as Home » Forums » General » Log Book.

However, when I click on one of the breadcrumb links it only goes back to the basic site url structure – such as “General” goes back to http://www.mysite.com/general when it actually should go to

http://www.mysite.com/forums/general

How do you guys suggest I go about fixing this?

Try this instead:

function breadcrumbs($separator = ' » ', $home = 'Home') {
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");
    foreach ($path AS $x => $crumb) {
        $title = ucwords(str_replace(Array('.php', '_', '-'), Array('', ' ', ' '), $crumb));
        $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";  
        $base = $base.$crumb.'/';
    }
    return implode($separator, $breadcrumbs);
}

Note the changed line $base = $base.$crumb.'/';
