Snippets are useful for adding logic to websites. They can be used to create menus, determine who is logged in, or any other thing possible with the API.
Usage
Cached:
[[snippetName]]
Uncached
[!snippetName!]
Accessing Snippets via the MODx API
Snippets can also be run inside of other snippets by using the MODx API:
Usage
$modx->runSnippet('snippetName' [, $params]);
You can optionally pass parameters to your snippet
$params => array('dog' => 'Max');
$modx->runSnippet('mySnippet', $params);
Then inside your Snippet ("mySnippet"), you will have access to the corresponding variables via PHP's extract function, or you can access all parameters inside of the $modx object:
// inside "mySnippet" print $dog; // prints 'Max' print_r( $modx->event->params ); // prints array('dog' => 'Max');
