Split a placeholder from in a migxdb call.

I'm using migxdb for a complex gallery system I've named artGallery. I have set up numerous multi-select list tvs that feed into my artGallery. For example I have a tv named "color" that has the following multi-select options.

yellow||blue||green||red||yellow, etc

In artGallery some images have a value of just "yellow" while others may have "yellow||blue"

If there is just one value I'd like an output that looks like this when there is one value:

<li<a href="yellow.html">yellow</a></li>

and like this when there are two values:

<li<a href="yellow.html">yellow</a></li><li<a href="blue.html">Blue</a></li>

My chunk works fine with one value but with two value I get this:

<li<a href="yellow||blue.html">yellow||blue</a>

This makes sense when you see the chunk code:

						<div class="relatedGalleries">Related Galleries</div>	
				
						<ul>
							
							<li class="archiveButton" id="[[+project]]"><a href="[[+project]].html">[[+project]]</a></li>
							
							<li class="archiveButton" id="[[+year]]"><a href="[[+year]].html">[[+year]]</a></li>
				
							<li class="archiveButton" id="[[+color]]"><a href="[[+color]].html">[[+color]]</a></li>
							
							<li class="archiveButton" id="[[+media]]"><a href="[[+media]].html">[[+media]]</a></li>				
				
						</ul>

My is how to I get the [[+color]] placeholder to template itself out as different chunks if there are two values?

try it like that:

snippet loopDelimited:

$delimiter = $modx->getOption('delimiter',$scriptProperties,',');
$value = $modx->getOption('value',$scriptProperties,'');
$tpl = $modx->getOption('tpl',$scriptProperties,'');
$outputSeparator = $modx->getOption('outputSeparator',$scriptProperties,"\n");

$values = explode($delimiter,$value);
$idx = 1;
foreach ($values as $value){
    $item = array();
    $item['value'] = $value;
    $item['_idx'] = $idx;
    $output[] = $modx->getChunk('tpl',$item);
    $idx++;
}

return implode($outputSeparator,$output);

[[loopDelimited? &value=`[[+color]]` &delimiter=`||` &tpl=`colorTpl`]]

colorTpl:

<li<a href="[[+value]].html">[[+value]]</a></li>

Hi Bruno, thanks for your help. I tried the above solution but it didn't produce anything. Was a blank output.

I made the snippet, Put the snippet call inside my migxdb template, and saved the colorTPL as a chunk. Is there something I'm missing?

this line was wrong:

$output[] = $modx->getChunk('tpl',$item);

$delimiter = $modx->getOption('delimiter',$scriptProperties,',');
$value = $modx->getOption('value',$scriptProperties,'');
$tpl = $modx->getOption('tpl',$scriptProperties,'');
$outputSeparator = $modx->getOption('outputSeparator',$scriptProperties,"\n");
 
$values = explode($delimiter,$value);
$idx = 1;
foreach ($values as $value){
    $item = array();
    $item['value'] = $value;
    $item['_idx'] = $idx;
    $output[] = $modx->getChunk($tpl,$item);
    $idx++;
}
 
return implode($outputSeparator,$output);
