How can I call Ditto for current document ID from chunk?

Hello,

I want to create a chunk with the basic Ditto call so I don’t have to go through each document and change Ditto parameters when I want something different.
So I thought to create a chunk and call Ditto every time for the current document ID (identical to the FormBlogComments chunk). The problem is I always get a MODx Parse Error sad

My chunk code is:

[!Ditto? &tpl=`DittoTemplate` &startID=`[~[*id*]~]` &summarize=`10` &descendentDepth=`0` &multiLevel=`0` &paginate=`1` &showPublishedOnly=`1` &trunLen=`500` &commentsChunk=`FormBlogComments`!]

I’ve tried also with [~id~] but no luck.
Can anyone help me please? Do I have to create a snippet for this Ditto call?

Thank you very much!

Boby, any chance you could post the parse error? Might help narrowing down the issue.

Yes, sure

I just realized, when I call [~[*id*]~] it gives me the document alias.suffix (mypage.html) and that is probably causing the error. Can I somehow get the numeric ID of current browsing document and not the alias?

And BTW, I’m using MODx 0.9.2.1 and Ditto 1.0.2

Thanks, Boby.

You may well be right. To get just the ID, use: [*id*]

Try that and see if it works.

I’ve done that now and tested, it really get’s the numeric ID. However I also tried to call Ditto with an available ID:

[!Ditto? &startID=`39` ... !]

And I get the same error like above sad

Could it be actually a problem with Ditto?

Ok, and just to make sure I call the chunk correct...
My chunk is called "DittoBlog" and I call it in a cached document with {{DittoBlog}}. Is this correct?

I just tried for a half hour to duplicate this error with no luck. Although I did notice something interesting. Calling the snippet cached vs uncached in the chunk made a difference as to what documents were retrieved. Jason, could this be an issue with documentMap being in the cache?

@Boby, try everything uncached.

If I use multiple startID’s it works, but I have to enter them manually, [*id*] is not working sad

This works:

[[Ditto? &startID=`39,63` ... ]]

This doesn’t:

[[Ditto? &startID=`63` ... ]]

But it does not work only when calling from a chunk, if I call Ditto directly from a document with multiple ID’s it works perfect.

@ Mark

I think I’ve found a little bug. I’m not exactly sure when this happens, first I thought it’s when there is only one parent document with no subdocuments, so nothing to show, but sometimes it’s working sometimes not. The problem is that $resource is not always and array and when following code is compiled:

$resource = array_values($resource);

the error pop-ups because it can not handle only arrays.

So I’ve added one more validation criteria to snippet.ditto.php:

There is this code (line 344)

if (count($resource) < 1) { return $emptyText."\n"; }

I have replaced it with:

if (!is_array ($resource) || empty ($resource)) { return $emptyText."\n"; }

Thanks guys!

This has already been reported in the Ditto support thread and Ditto 1.0.3 is coming soon to a MODx install near you.

The reason [*id*] does not work correctly at the moment is because of too strict of a regex in a cleaning function. This will be removed in the next release. For now, just run in production mode as it bypasses the check.
