Site structure is:

News (3)
|____News numero 1 (4)
|____News numero 2 (6)

I have created 3 TV for my template to use with Ditto:
titolo -> Input Type=Text area
immagine -> Input Type=Image
descrizione -> Input Type=Text area (mini)

Then I created the chunk template_news for Ditto call

<h1>[+tvtitolo+]</h1>
[[verifica]]
<p>[+tvdescrizione+]</p>

The snipper [[verifica]] is a check for TV immagine. If is present return the HTML image tag else return nothing.

<?php
$output='';
$idimmagine=$modx->getTemplateVarOutput('immagine',$modx->documentIdentifier);
if($idimmagine['immagine']!='') $output.='<img src="' . $idimmagine['immagine'] . '" />';
return $output;
?>

In the News page (id=3) I call:

[[Ditto? &tpl=`template_news` &startID=`3` &summarize=`3` ]]

Now the problem is in the snippet [[verifica]] on the parameter $modx->documentIdentifier
It return 3 (id of page/container News) and don’t show the image that I have inserted in TV, but I want that it return 4 for first news, 6 for second news, etc...

How I make this loop in php? Is possible?

Ciao,

you have to change the code of your snippet to pass the id parameter

[[verifica? &docid=`[+id+]`]]

$id = (isset($docid)) ? $docid: false;
$output='';
if(is_numeric($id)){
$idimmagine=$modx->getTemplateVarOutput('immagine',$id);
if($idimmagine['immagine']!='') $output.='<img src="' . $idimmagine['immagine'] . '" />';
return $output;
}

You’re welcome.

The new version (2.0) of ditto ~~will~~ supports PHx so you won’t have to use anymore your own snippet to check if the Tv has a value.

Your tpl chunk will look something like this

<h1>[+titolo+]</h1>
[+immagine:isnot=``:then=`[+immagine+]`+]
<p>[+descrizione+]</p>

That will reduce the required db queries
