MODx API

MODx provides APIs that you can use to avoid recreating commonly-used functions. The MODx APIs are accessed through the DocumentParser object $modx. You can explore more of the MODx internals by trying the following at the top of the helloworld snippet, after the <?php open tag:

echo '<pre>';
print_r($MODx);
echo '</pre>';
exit;

This will print the entire structure of the $modx object, so you can learn a great deal from the output.

You can use any of the available API functions from within the snippet using the $modx->functionname() syntax. In fact, the functions that you have been using to set the placeholders, and to display a chunk, are themselves a part of the MODx API that is available through the $modx object.

Next, we will see examples of a few of them:

• $modx->getDocument(1) will get all the property and values of resource 1

• $modx->getAllChildren(1) will get all of the child resources of resource 1

• $modx->getTemplateVars will return an array of all...
