[solved]Parse datas into chunk template with api

Hello,

I’m attempting to output datas and parse them into templates (chunks) before displaying, with revo beta 5 api.
Here is my buggy attempt to adapt the sample from documentation :

			$resources = $modx->getCollection('modResource',array('published' => 1,));
						
			$rowChunk = $modx->getChunk('tplEntries');  
			
			foreach ($resources as $resource) {
				
				$properties = $resource->toArray();  
				$properties['rowCls'] = 'test'; 
				
				$output .= $rowChunk->process($properties);


			}

In the original sample it doesn’t store any resource in a variable. It retrieves datas, and basta, like this :

$modx->getCollection()

In my case, before performing a foreach, I store the datas in $resources :

$resources  = $modx->getCollection('modResource',array('published' => 1,)); )

This causes an error when calling process() afterwards.

When removing $resources (as in sample) it doesn’t output any error now but how do I loop through values ( because without array, foreach won’t loop) :

$modx->getCollection('modResource',array('published' => 1,)); )

foreach ($resources as $resource) {
// stuff here will never be executed
}

Any clue would be greatly appreciated

Here’s how I do it:

<?php
$output = array();
$resources = $modx->getCollection('modResource',array('published' => 1,));
foreach ($resources as $resource) {
    $properties = $resource->toArray();
    $properties['rowCls'] = 'test';
    $output[] = $modx->getChunk('tplEntries', $properties);
}
return implode("\n", $output);
?>

But be careful; if you have a lot of Resources, getting a collection of all of them with all of their fields (including the content) will use a very large amount of memory. You can use xPDOQuery::select() to accomplish this (see the getResources Snippet for an example of this usage when retrieving a collection of Resources).
