helo again. my issue came up when I tried to call a content (document) with the extra parameter (as index.php?id=48&param=xyz). this param would be used as parameter for a ditto call to show document(another as called - param is not equal id) in different view as using as with associated template in the called document.

i simply dont know how to get variables through url metod. saw it somewhere for sure, but cant find it again.

thanx for an answer

In a snippet use the $_GET like in a ’normal’ php script.

In Ditto you can use the request extender.

Here is an example that I used on my site to get the Tag to be used as a title:
```
<?php
// diplay tags request
if(isset($_GET['tags'])) {
    $title = $modx->documentObject['pagetitle'];
    return $title.": ".htmlspecialchars($_GET['tags'])." ([+total+])";
} else {
    $title = $modx->documentObject['longtitle'];
    $introtext = $modx->documentObject['description'];
    return $title.$introtext;
}
?>
```
