Hi,

I’d like to get the value of a specific TV i’ve created in a parent document (i’m using Modx 1.0.4)

i’ve got a snipped called ZoomImage

<?php
$parent = $modx->getParent($iddoc,1,$field);
return $parent[$field];
?>

this works for the usual Modx objects ( http://rtfm.modx.com/display/MODx096/Document+Object )

[!ZoomImage? &iddoc=`[*id*]` &field=`introtext`!]

but to get the value of a personal TV (let’s name it "SpecialPic")

[!ZoomImage? &iddoc=`[*id*]` &field=`SpecialPic`!] or
[!ZoomImage? &iddoc=`[*id*]` &field=`[*SpecialPic*]`!] or
Anything else...

I’ve got a sql error (SpecialPic is not in the database !!!)

Any Idea ? (it’s been 3 days of searching)

Thanks,

Max

EDIT : the TV (SpecialPic) is authorized in all the templates i’m using

That function only works for the resource variables; it uses the site_content table. That’s why it complains about not finding it in the database.

You’ll need to use the getTemplateVarOutput() API function; here’s the example from the wiki

$tvPr = $modx->getTemplateVarOutput(array("price"),$docid='2',$published=1);
echo $tvPr['price'];

Just replace the $docid=’2’ with the $parent variable. You’d probably be just as well off using the $modx->documentObject[’parent’] yourself since that’s what the getParent function uses, and all you want from it is the parent ID.

$parent = $modx->documentObject['parent'];
$tv = $modx->getTemplateVarOutput(array("$field"),$parent);
return $tv[$field];

I’ll try this tomorrow to get my own snippet, but GetField works perfectly for what i’ve asked.

Thanks anyway, both of you.
