Modx getresources foreach

Question

I have this snippet :

<?php
$list = $modx->runSnippet('getResources', array(
'parents'=>'16',
'depth'=>'1',
'includeContent'=>'1',
'limit'=>'1'
));

$output = explode(',', $list);
//print_r($list);

foreach($output as $i) {
  //echo $i;
  foreach($i as $key => $value) {
    echo $key.' : '.$value.'<br />';
  }
}

With print_r I can see the array ;-)

But using the foreach loop... nothing print !

Thanks for your help...

Answer 1

The problem might be that you are calling 'explode' on an array when it should be taking a string.

Not sure exactly what your $list array looks like, but perhaps try this instead:

foreach ($list as $i) {
  foreach ($i as $key => $value) {
    echo $key.' : '.$value.'<br />';
  }
}

EDIT Have tested this and $list is not an array but a pre-formatted string meant for debugging:

<pre>Array
    (
    [tpl] => 
    [tplOdd] => 
    [tplFirst] => 
...
</pre>

I'm not sure exactly what you want to achieve, but it's usually better to use the tpl parameter to format results using a Chunk.

getResources is designed for listing Resources for front end display and is not generally used to retrieve raw data.
