Bread Crumb Trail

[Vivid Lust]

The code im using for a bread crumb trail is currently not working!

 

Code:

 

<?php
$id = $_GET['id'];
if ( strlen( $id ) < 1 )
	$id = "home";

$pages = array(
	home => array( id=>"home", parent=>"", title=>"Home",
			url=>"index.php" ),
	users => array( id=>"company", parent=>"home", title=>"Company",
			url=>"index.php?page_id=5" ),
	jack => array( id=>"tutorials", parent=>"home", title=>"Tutorials",
			url=>"index.php?page_id=7" )
	);

	function breadcrumbs( $id, $pages )
	{
	  $bcl = array( );
	  $pageid = $id;
	  while( strlen( $pageid ) > 0 )
	  {
		$bcl[] = $pageid;
		$pageid = $pages[ $pageid ]['parent'];
	  }
	  for( $i = count( $bcl ) - 1; $i >= 0; $i-- )
	  {
		$page = $pages[$bcl[$i]];
		if ( $i > 0 )
		{
			echo( "<a href=\"" );
			echo( $page['url'] );
			echo( "\">" );
		}
		echo( $page['title'] );
		if ( $i > 0 )
		{
		echo( "</a> | " );
		}
	  }
   }
   ?>

Breadcrumbs: <?php breadcrumbs( $id, $pages ); ?>

 

Have a look on the following site, click on two other links on the menu and you'll see that the breadcrumb trail always shows home although i had specified the other pages in the above code.... Any ideas upon what the problem is and how it can be fixed?

Thanks in advanced!

Simplify the function i.e.

 

function breadPath($path) {
$crumb = array();
foreach($path as $id => $val) {
	$crumb[] = "<a href='index.php".(($id !=0) ? "?pageId=".$id."" : "")."'>".$val."</a>";
}
return implode(" >> ", $crumb);
}

$path = array("Home",5 => "Page 1", 6 => "Page 2");
echo breadPath($path);

then I cant specify the parent.. ?

Yes. Heres another method.

 

function breadPath($path,$pathTxt) {
$pathArray    = explode("|",$path);
$pathTxtArray = explode('|',$pathTxt);
$link = array();
for($x = 1; $x < count($pathTxtArray); $x++) {
	$link[] = '<a href="index.php?pageId='.$pathArray[$x].'">'.$pathTxtArray[$x].'</a>';
}
return implode(" >> ",$link);
}

// page path: Home|Page 1|Sub Page 1
// page id path: 0|1|69
$path = "0|1|69";
$pathTxt = "Home|Page 1|Sub Page 1";
echo breadPath($path,$pathTxt);

 

I would store the pages in a database table with the following fields:

 

pages

------

pageId

parentId

title

path

pathTxt

 

So if I am on pageId 69 I can get the record for pageId 69. The path may be 0|1|69 (its parent being 1) and the pathText would be Home|Page 1|Sub Page 1. Run the values through the function.

 

So the table records may look like:

0 , -1 , Home , 0 , Home

1 , 0 , Page 1 , 0|1, Home|Page 1

69, 1, Sub Page 1, 0|1|69, Home|Page 1|Sub Page 1

 

Get it?
