[Revolution, solved] Does $modx->getChunk actually do its job?

Hello there,

well, I ran into some issues using $modx->getChunk and I’m using beta 5.

[[snippet? &tpl=`existingChunk`]]

$tpl = $modx->getChunk($tpl);

[...] define $params [...]

return $tpl->process($params);

Fatal error: Call to a member function process() on a non-object in /path/to/file.php on line 19

By this actually works:

$tpl = $modx->getObject('modChunk', array('name' => $tpl));

[...] define $params [...]

return $tpl->process($params);

So, why is this function mentioned in the manual anyway? xD Or is it supposed to work?

I’m curious laugh

You do not need to call process(); getChunk does not return an object, but the results of processing the chunk using the properties you pass, e.g.

<?php
return $modx->getChunk($tpl, $scriptProperties);
?>

IOW it handles getting the modChunk object instance and calling process() for you.

Hi I'm stuck with this output, please suggest what's wrong:

        $responsexml = @simplexml_load_string($result, 'SimpleXMLElement', LIBXML_NOCDATA | LIBXML_NOBLANKS);
	foreach ($responsexml as $hotelresponse)
	 {
		$hotelname = ($hotelresponse->HotelInfo->Name);
		$hoteldestination = ($hotelresponse->HotelInfo->Destination->Name);
		$hotelcategory = ($hotelresponse->HotelInfo->Category);
		$hotelimage = ($hotelresponse->HotelInfo->ImageList->Image[0]->Url);

		$returnedoutput .= $modx->getChunk('_testxmlchunk',array(
  			'hotel' => $hotelname,
  			'destination' => $hoteldestination,
  			'category' => $hotelcategory,
  			'image' => $hotelimage,
		));
          }

return $returnedoutput;

_testxmlchunk chunk template:

<li>this is [[+hotel]] is in [[+destination]] category [[+category]] pic <img src="[[+image]]"/></li>

It doesn't output anything

but when I do this.. it works

$responsexml = @simplexml_load_string($result, 'SimpleXMLElement', LIBXML_NOCDATA | LIBXML_NOBLANKS);
	foreach ($responsexml as $hotelresponse)
	 {
		$hotelname = ($hotelresponse->HotelInfo->Name);
		$hoteldestination = ($hotelresponse->HotelInfo->Destination->Name);
		$hotelcategory = ($hotelresponse->HotelInfo->Category);
		$hotelimage = ($hotelresponse->HotelInfo->ImageList->Image[0]->Url);

		$returnedoutput .= $hotelname.' '.$hotelimage.' '. $hoteldestination.' '.$hotelcategory.';
         }

return $returnedoutput;

any suggestion... Did I miss something? I want to template my snippet.

You may need to explicitly cast those SimpleXML elements to string when putting them in the array of properties for getChunk, i.e.

        $returnedoutput .= $modx->getChunk('_testxmlchunk',array(
            'hotel' => (string)$hotelname,
            'destination' => (string)$hoteldestination,
            'category' => (string)$hotelcategory,
            'image' => (string)$hotelimage,
        ));

In your second example, you are implicitly doing so by concatenating them with ' '.

Thanks opengeek that also works too.
I forgot that since those variables ($hotelname,$hoteldestination,$hotelcategory,$hotelimage) are object, it should be passed as a string.
