How to sort Modx Ditto documents ID when using &documents?

I found very nice extender for Ditto Modx.

When using snippet Ditto with custom page Ids, you have strange sorting - I haven't even understood which one.

For sorting documents as you write in &documents=[x, xx, xxx, xxxx] you shoul use the ditto-extender below.

Write Ditto callout this way:

[[Ditto? &tpl=razdel200 &documents=[1,4,3,5,212,23,44] &extenders=customsort ]]

You should save file "customsort.extender.inc.php" in assets/snippets/ditto/extenders/

<?php

if (!function_exists('customsort'))
{
function customsort($a, $b)
{
$pos_a=array_search($a['id'],$GLOBALS['documents']);
$pos_b=array_search($b['id'],$GLOBALS['documents']);

if ($pos_a == $pos_b)
{
return 0;
}
return ($pos_a < $pos_b)?-1:1;
}
}

$GLOBALS['documents']=explode(',',$documents);
$orderBy["custom"][] = array ("id", "customsort");
$ditto->advSort = true;

?>

<?php

if (!function_exists('customsort'))

{

function customsort($a, $b)

{

$pos_a=array_search($a['id'],$GLOBALS['documents']);

$pos_b=array_search($b['id'],$GLOBALS['documents']);

if ($pos_a == $pos_b)

{

return 0;

}

return ($pos_a < $pos_b)?-1:1;

}

$GLOBALS['documents']=explode(',',$documents);

$orderBy["custom"][] = array ("id", "customsort");

$ditto->advSort = true;

Then documents are in the order you needed.
