Retrieves a collection of xPDOObjects by the specified xPDOCriteria.

If none are found, returns an empty array.


API Docs: https://api.modx.com/revolution/2.2/db_core_xpdo_xpdo.class.html#\xPDO::getCollection()

array getCollection (string $className, [xPDOCriteria|array|str|int $criteria = null], [bool|int $cacheFlag = true])

Remember, if you are using xPDO map and class files that were generated from XML schema, the classname is not the same as your table name. If in doubt, have a look at the schema XML file, e.g.

<object class="MyClassName" table="my_class_name" extends="xPDOObject">


Get a collection of Box objects with a width of 40.

$boxes = $xpdo->getCollection('Box',array(
   'width' => 40,

Get Pages

Often getCollection is used inside MODX Snippets, so you will call it via the $modx object and you will be fetching built-in MODX object collections, such as pages.

$pages = $modx->getCollection('modResource', array('template' => 3));

Know Your Objects! Remember that you need to call the collection by its object name. You may find it quite handy to keep open your core/model/schema/modx.mysql.schema.xml file so you can review your object names, e.g. "modResource" for pages, or "modChunk" for chunks etc.
