Create Dynamic Bread Crumbs?

austingecko

I'd like to have on the page bread crumbs like, "Home > Main Topic > Sub Topic" without using HTML because the user could get to Sub Topic a number of ways.

Is there a script or simple routine to create dynamic bread crumbs?

thanks

One way that might be a good possibility, although I'm not sure... try using hidden fields... you know store the enviroment variable from where the person came from in the hidden field... or... use session/cookies, and just keep appending where they came from to each other... shrugs I don't have time to create a script for it, but those ideas will get you on the right path.

Here is a really simple way:

<?php
$expl = explode("/home/",$HTTP_SERVER_VARS["REQUEST_URI"]);
$tmp = $expl[1];
$expl = explode("/",$tmp);
$article_id = $expl[count($expl)-1];

echo "<a href='/home/'>Home</a> &gt; ";

for ($x=0; $x < count($expl)-1; $x++) {
	echo "<a href='/home/";
	for ($z=0; $z < $x; $z++)
		echo $expl[$z] . "/";
	echo $expl[$x] . "/'>" . $expl[$x] . "</a> &gt; ";
}

echo "<a href='/";
for ($z=0; $z < $x; $z++)
	echo $expl[$z] . "/home/";
echo $expl[$x] . "/'>" . $expl[$x] . "</a>";

echo "<br><br><br><a href='la/'>la</a>";
echo "<br><a href='bla/'>bla</a>";
echo "<br><a href='blah/'>blah</a>";
echo "<br><a href='a/'>a</a>";

echo "<br><br><a href='/home/Downloads/'>Downloads</a>";
?>

Make a file called Home (no extension at all) and a file called .htaccess with this in it:

<FilesMatch "^home$">
    ForceType application/x-httpd-php
</FilesMatch>

Now if you goto yoursite.com/home/ you'll see what happens.

I put some links so that you can see how to make them properly.

You may want to put a limit on it as they could make it as long as they wanted 🙂

Thats an easy way to get crumbs. For including content there are 2 ways:
- Have all your pages in the root dir and just use include($expl[$x]);
- Have the last term refer to a unique value in a database and get all the data/values..... like that

Hope that helps.
