Using placeholders in Input Option Values (in a MIGX form)

I am fairly new to modx. I have tried to find a solution for myself the past few days and I think that I am missing something.

I created two lists;
1) Debtors
2) User

I use migx to manage the debtors and the users. I like to have a list of users within a debtor (which is some kind of group).

I managed to get that working. I have a grid and can Add and Edit users. I created a snippet getUserlist. No problems there. It all seems to work.
I want to extend the logic with that Snippet. I only want to show the users which are not assigned (for example). And of course the current user id.

I tried everything; @CHUNK binding, Input Option Values with @EVAL binding, an InputTV. Even a field with Description_is_code.

It seemed so easy. Entering the following statement in "Input Option Values" in the tab "Input Options" .


(modx_user_id and debtor_id are fields in the database/xPDO-class)

If I use fixed values (like $modx->runSnippet('getUserlist',array("debtorid" => "2"....) it's Ok. But the placeholders (like [[+debtor_id]]) are not replaced.
I tried @EVAL return $modx->runSnippet('getUserlist',array("debtorid" => "@CODE [[+debtor_id]]","currentuser" => "[[+modx_user_id]]"));
No luck there.

This almost seemed to work. On the tab "Field":

Description_is_code=YES
Description:


But then I only get a text and no formelement (screenshot).

I looked at https://forums.modx.com/thread/86375/creating-dynamic-listbox-tv-with-help-of-migx but this was about getResources and I do not how this work on custom tables.
I also looked at https://forums.modx.com/thread/90099/migxdb-passing-record-property-to-input-option but the solution looks a little bit overwhelming.

My question is: "Is it possible to access the current “object” with placeholders or API-calls within something like this in migx??"

Example:


Thanks for you help. By the way; I am using modx revo 2.2.14-pl and migx 2.81.

I'm unsure where you have this listbox.
Is it on a MIGXdb - CMP?

If it is in a MGXdb - CMP, then you should get the current object_id with

inside your getUserlist - snippet

Or is it a MIGXdb - grid nested into another MIGXdb ?

Could you post your whole MIGX - configurations (doing import/export at the MIGX-configuration-grid)

Thanks Bruno!

I use this in the MIGXdb-cmp (see attached screenshot).

$_REQUEST['object_id'] seems to work. I get the ID of the selected record. I can probably get it working by accessing the DB, use the object_id to get the stored values of the record with ID=object_id.
I suppose it is not possible to access the values of my own properties like "debtor_id" in the CMP-form?!
