Return statement not working ?

[iceraider]

Ok this is a weird one.

For some reason I have this code in my function..

			$backwords = array_reverse($backwords);
			foreach ($backwords as $key=>$itm)
			{
				$newDir .= $itm['directory'].'/';
			}

		return $newDir;

now it will return something if $newDir only gets 1 item, if the foreach puts 2 items in there.. it returns nothing.

Please Help

I use this to print it..

echo $dis->folderView($items,$id,false);

can you maybe modify the code slightly and then run it so i can see what the array looks like?

change
$backwords = array_reverse($backwords);
foreach ($backwords as $key=>$itm)

to

$backwords = array_reverse($backwords);
print_r($backwords);
foreach(....

and post the array printout.

thanks.

This is the one that works

Array ( [0] => Array ( [id] => 321 [parent] => 0 [desc] => Dirt Bike (Moto Cross) [directory] => motocross [org] => 1 ) ) 

The one that doesn`t

Array ( [0] => Array ( [id] => 321 [parent] => 0 [desc] => Dirt Bike (Moto Cross) [directory] => motocross [org] => 1 )
        [1] => Array ( [id] => 333 [parent] => 321 [desc] => Air Filters [directory] => Air_Filters [org] => 2 ) )

strange, it seems to work for me. here is the code i made and it outputs Air_Filters/motocross

<?php

$arr = array( 
         array("id" => 321, "parent" => 0, "desc" => "Dirt Bike (Moto Cross)", "directory" => "motocross", "org" => 1),
	   array("id" => 333, "parent" => 321, "desc" => "Air Filters", "directory" => "Air_Filters", "org" => 2)
       );


function junk($inArr)
{
	$inArr = array_reverse($inArr);

foreach ($inArr as $key=>$itm) {
	$newDir .= $itm['directory'].'/';
}

return $newDir;
}

echo junk($arr);

?>

Listen I had that function in a class.

So what I had to do was this ..

class Display
{

var $folderView;

/*------------------------------------------------------+
|  Show Folder View				|
+------------------------------------------------------*/
function folderView($items,$id,$backwords=array())
{

	global $dis,$newDir;

	$backwords[$id] = $items[$id]; 

	if($items[$id]['parent'])
	{
		$dis->folderView($items,$items[$id]['parent'],$backwords);
	}
	else
	{

		$backwords = array_reverse($backwords);
		unset($this->folderView);
		foreach ($backwords as $key=>$itm)
		{
			$this->folderView .= $itm['directory'].'/';
		}
	}	

}
}

$dis = new Display;

Then I ran in my script..

	if($id > '0')
	{
		$dis->folderView($items,$id);
		$theDir = $dis->folderView;
	}

For some reason that worked .. but in my class if I use

return($this->folderView);

and in my script I put

echo $dis->folderView($items,$id);

Nothing prints, so could someoen tell me why I cant return the value without it being blank.
