Answered Getting resource properties in Revo vs. Evo

Hello,

I'm updating some sites from Evo to Revo.

There are some PHP 5.2 scripts written by myself to combine some data from different tables with MODX Evo documents.

I used this to get the value of a Evo TV named bildKursdetail:
```
$bild = $modx->getTemplateVarOutput(array("bildKursdetail"),$docid=$kurs_modx_id,$published=1);
```
I tried with
```
$bild = $modx->modTemplateVar->renderOutput(array("bildKursdetail"),$docid=$kurs_modx_id,$published=1);
```
This doesn't work.

To get an array of a resource's data from an doc id stored in $kurs_modx_id I used this code:
```
$document=$modx->getDocument($kurs_modx_id);
```
This does not work anymore. I tried:
```
$document = $modx->getObject('modResource', array('id'=> $kurs_modx_id));
```
but this did not work, as in the next step I had
```
$alias=$document['alias'];
```
This is now resulting in
```
Fatal error: Cannot use object of type modDocument_mysql as array ... 
```
I looked into the reference docs, but I'm not sure where to start ...

I'm not into PHP too deep anymore, but I hope to be able to transfer the scripts to work with Revo.

Can anyone give some hint on this?
Thanks!

```
$tv = $modx->getObject('modTemplateVar', array('name' => 'bildKursdetail'));
$bild = $tv->renderOutput($kurs_modx_id);  // rendered output
$bild = $tv->getValue($kurs_modx_id);  // raw value
```
If you happen to have the resource object already, either by getting it with getObject() or referencing $modx->resource, you can also do this
```
$bild = $modx->resource->getTVValue('bildKursdetail');
```
or
```
$bild = $resource->getTVValue('bildKursdetail');
```
Both of the above will get you the rendered TV output.

This (below) should definitely work, though it's more complicated than necessary, since you have the Resource ID:
```
$document = $modx->getObject('modResource', array('id'=> $kurs_modx_id));
```
This should work also:
```
$document = $modx->getObject('modResource', (int) $kurs_modx_id);
```
Then,
```
$alias=$document->get('alias');
```
