Get a TV value in toArray()

Hi,

I’m using $modx->getCollection() to query for a collection of resources in a snippet. I then convert the resource to an array using toArray() and pass into a chunk. However, I cannot retrieve the value of a TV called "main_image" on this resource using [[*main_image]] or [[+main_image]] in the chunk.

How can I include the TV values in toArray() so I can reference them in a chunk. I’ve cut this code down a bit but it shows the meat and bones of it - it was inspired by the templating your snippets page in the modx documentation (

$query = $modx->newQuery('modResource');
$query->where(Array(
    'hidemenu' => 0,
    'published' => true,
    'deleted' => false
));

// Get the resources
$resources = $modx->getCollection('modResource', $query);

$itemOutput = '';
foreach ($resources as $resource)
{
    $resourceArray = $resource->toArray();
    var_dump($resourceArray); <-- TV is not present in this array
    $itemOutput .= $modx->getChunk($itemTemplate, $resourceArray); <-- chunk contains [[+main_image]] but it is rendered blank
}

My environment is modx 2.0.4-pl2 on FreeBSD 8.1, Apache 2.2.16, MariaDB/MySQL 5.1.50, PHP 5.3.3.

Thanks!

Andy

Getting TVs in a Resource is a bit more complex, since there are a possible unlimited # of TVs. However, you can do so in your loop:

foreach ($resources as $resource) {
        $templateVars =& $resource->getMany('TemplateVars');
        foreach ($templateVars as $tvId => $templateVar) {
            $tvs[$templateVar->get('name')] = $templateVar->get('value');
        }
    $resourceArray = array_merge($resource->toArray(),$tvs);
    $itemOutput .= $modx->getChunk($itemTemplate, $resourceArray);
}

If you want to process those TVs (ie, process any tags within them, but it takes up more processing time and memory), you can do:

$tvs[$templateVar->get('name')] = $templateVar->renderOutput($resource->get('id'));

instead. If the whole purpose of your snippet is to iterate over Resources, though, I’d recommend using the getResources Extra, as it’ll be far better and more up-to-date than most ad-hoc snippets.

Hi Shaun,

That worked brilliant, thanks.

It is part of a larger snippet that builds up a large section of my home page - I just cut it down enough to show the issue - but thanks for the tip about getResources, I’ll take a look into it.
