BreadCrumb Navigation

Tozzie · 09-28-2007, 05:07 AM

Hey again!

i was wondering if someone could help me out.
What i want to do, is use a breadcrumb style navigation script, what i want it to do it look at the url, and take certain things from it,
so if the link is this: index.php?page=tutorials&page=list&cat=photoshop
it would make "Site Name > Tutorials > Photoshop"

Thanks to anyone that can help! :D

PHP Code:


			
$page = $_GET['page'];
$cat = $_GET['cat'];

echo $pagename . ' > ' . $page . ' > ' . $cat;

Why do you have a page list after the page tutorial? It'll only confuse everything.. remove it =(

I've had fun writing this function :) ! Works like a dream. Even adds in the links for you and best of all, it's all automatic. Don't forget to give TalkPHP.com a mention if you use it! Please.

PHP Code:


			
function get_crumbs($szSeperator = ' &gt; ')
{
    preg_match_all('/[a-z0-9]+=+([a-z0-9]+)&?/i', $_SERVER['QUERY_STRING'], $aMatches);
    
    $iCount = 1;
    
    for($iIndex = 0; $iIndex < count($aMatches[1]); $iIndex++)
    {
        $szQuery =& $aMatches[0][$iIndex];
        
        if(substr($szQuery, -1) == '&')
        {
            $szQuery = substr($szQuery, 0, -1);
        }
        
        $aQuery = array();
        $szItem =& $aMatches[1][$iIndex];
        
        for($iCycle = 0; $iCycle < $iCount; $iCycle++)
        {
            $aQuery[] = $aMatches[0][$iCycle];
        }
        
        $iCount++;
        
        $szItem = '<a href="?' . implode('&amp;', $aQuery) . '">' . ucwords(strtolower($szItem)) . '</a>';
    }
    
    return implode($szSeperator, $aMatches[1]);
}

echo '<a href="page.php">TalkPHP.com</a> &gt; ' . get_crumbs();

Interesting function, Wildhoney, but sadly it won't cope (in terms of display order) if the key/value pairs come in a differently. E.g. ?act=list&cat=photoshop&page=tutorials rather than page, act, cat.

Yep. I realise that. It's its only downfall really. However, for what he asked, it is perfect! The idea itself was flawed, not the code. As long as users don't go switching arguments then you're laughing.
