Sorting by custom document calls...

Hello all, have a quick question as it relates to ordering documents when pulling certain docs into a page.

i have the following code:

[[Ditto? &documents=`153,155,186,184` &display=`100` `&dateFormat=`%B %e, %Y` &sortBy=`title DESC` &tpl=`PartnersBox`]]

works just the way i want, however i want to order by the "&documents=" bit just as they are listed there "153,155,186,184" where 153 is at the top and 184 is the last one.

is there a way to do this with the "&orderby" code or is there another way? right now i have it set obviously by "title"

i have done a few searches in here however haven’t found what iam looking for

It sounds really easy but me either didn’t found any built in parameters that would keep the order as is.
Did you tried to use the menuindex? or is it something you don’t want to change?

If so, maybe you can try:
It would sound very inconvenient, but how about making a template variable for them?
for example:

Make A TV named ditto_index
Make it available to all of the templates of docs # 153,155,186,184
Set the doc #153’s ditto_index to 1
Set the doc #155’s ditto_index to 2
Set the doc #186’s ditto_index to 3
Set the doc #184’s ditto_index to 4
use &sortBy=`ditto_index`&sortDir=`ASC` parameter
If it works, try to remove the access of all the other templates, to prevent confusion ? (not so sure, but modx doesn’t delete them right? just don’t delete the template variable ditto_index)

or create an new ditto-extender with this code:

<?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;

?>

Interesting, how to call the snippet with that extender + use it for sorting? or is it done by the extender parameter only?

create a new extender in folder assets/snippets/ditto/extenders

name it e.g. sortByDocuments.extender.inc.php

call Ditto with [!Ditto? ................&extenders=`sortByDocuments`..........!]

and Ditto sorts the documents as they come in &documents
