Using the same snippet several times in the same page, with diffrent variables

Hey,

I’m using a snippet several times in the same page, and I’m transfering to it deffrent variables each time (&var=`value`).
The problem is that the snippets runs each time with the variable from the last call to the snippet.
e.g.:
If I have the following calls to the snippet:
[[snippet? &var=`one`]]
[[snippet? &var=`two`]]
[[snippet? &var=`three`]]

Then all the three outputs, will be according to the &var=`three` and the snippet ignores any other variable in the previous calls.
How can I fix this?

Thanx

Please post your snippet code and perhaps we can tell you what’s wrong...

k, here’s the snippet:

<?
require_once('assets/snippets/feed.inc.php');

$feedUrl = (isset($url)) ? $url : null;
$feedType = (isset($feedType)) ? $feedType : null;
$feedAmountItems = (isset($feedAmountItems)) ? (int) $feedAmountItems : 10;
$feedLayoutOuter = (isset($feedLayoutOuter)) ? $feedLayoutOuter : 'FeedsLayout_Outer';
$feedLayoutInner = (isset($feedLayoutInner)) ? $feedLayoutInner : 'FeedsLayout_Inner';

$feed = new feed();
$feed->feed_url($feedUrl);

$output = null;
$itemOutput = null;
$feedOutput = null;

if ($feed->data){
	$max = $feed->get_item_quantity($feedAmountItems);
	for ($x = 0; $x < $max; $x++) {
		$item = $feed->get_item($x);
		$itemOutput = '<a href="' . $item->get_permalink() . '">' . $item->get_title() . '</a>';
		$feedOutput .= str_replace('[+itemContent+]', $itemOutput, $modx->getChunk('FeedsLayout_Inner'));
	}
	$modx->setPlaceholder('feedContent', trim($feedOutput));
	$output = $modx->getChunk($feedLayoutOuter);
}
$feed = null;
return $output;

I call the snippet like this:

[!Snippet? &url=`file.xml`!]
[!Snippet? &url=`file2.xml`!]

Simple misuse of placeholders. You need to use instance specific placeholder names, or use something like $modx->parseChunk (or a simple str_replace call), to replace those variables in the chunk within the scope of the snippet itself.
