New page

{{howto|Advanced|[[Thomas Holz]] <vhskids@gmx.de>}}

Modifiers allow you to modify nodes on before they are used. To add functions like preUpdate use atkTriggerListener

'''Example of using atkTriggerListener:'''

Add the following code in your module_preload.inc (if this file is not present, create it in your module's directory):

<syntaxhighlight lang="php">
$modifiers[] = 'modules.node';
</syntaxhighlight>

In your module.inc:

<syntaxhighlight lang="php">
class mod_mymodule extends atkModule
{
function module_node_modifier(&$node)
{
atkimport("module.mymodule.myListener");
$node->addListener(new MyListener());
}
}
</syntaxhighlight>

now setup class.myListener.inc. The Listner contain the new functions. They will be called automatically by the node.

<syntaxhighlight lang="php">
atkimport("atk.utils.atktriggerlistener");

class MyListener extends atkTriggerListener
{

function preUpdate( &$record )
{
do some code....
return true;
}
</syntaxhighlight>
