Well, what I want to do is having a template variable for some documents which are like "articles" with some authors.

In this TV the options can be 1 or more (the authors) but, and here is the difficulty, each author have to be one of my site’s id (concretly one from inside one folder of my site).

I know that @EVAL cans evaluate php expressions but I don’t know how to get a expression which can get me a string wich the format "pagetitle1||pagetitle2||pagetitle3... " for using it like options for the Multi-Select variable.

Can somebody help me? Thanks.

I usually create a snippet and use @eval $modx->runSnippet....

Yes, but I didn’t know very much about PHP, but the words of the user xyzvisual was very helpful

:

$children = $modx->getDocumentChildren(PARENT_ID,1,0,'id,pagetitle', 'hidemenu=0','menuindex ASC,pagetitle', 'DESC');
$childrenCount=count($children);
//bucle que recorre el array de id
for($x=0; $x<$childrenCount; $x++) {
$output .=$children[$x]['pagetitle'].'||';
}
// To delete the last 2 separators
return  substr( $output, 0, -2);
