[Solved]How to get document parent id for cached ditto call(variable cached sip.

<?php
//---Name--
//chunkListParser_cached

//---About---
//This snippet was fastly created to be able to call the snippet chunkListParser cached to make it possible
//to call snippets within the chunks inserted by chunkListParser uncached.

//---Parameters---
//This snippet is written to be used with one parameter, &chunks, where you put the name of the TV that you
//would have used.
//Ex. [[chunkListParser_cached? &chunks=`functions_sidebar`]]

// identify the chunks
$docid = $modx -> documentIdentifier;
$chunks_result = $modx -> getTemplateVarOutput($chunks, $docid);

// use the chunks in the chunkListParser call
$snippet_output = $modx->runSnippet("chunkListParser", array(
	"chunks" => $chunks_result[$chunks],
	"wrapperdiv" => $chunks ));

//debug (if something does not work, the line below shows the variable values)
//$snippet_output = $snippet_output.", docid=".$docid.", chunks=".$chunks.", chunks_result[$chunks]=".$chunks_result[$chunks];

// output the chunkListParser results
return $snippet_output;
