Answered Simple nesting in MIGX

I'm trying to figure out how to do a basic MIGX within a MIGX. It's for an FAQ and all I'm after is having Categories which contain Questions and Answers:

Category A
- Question 1
- Answer 1

- Question 2
- Answer 2

Category B
- Question 1
- Answer 1

etc.

I've got the Questions and Answers set up with no problem.

Form tabs:



Grid columns:



Is there a simple way to add Categories (preferably that I can drag and drop the questions between)?

what about having a Listbox with categories, where to select the category from?

If you create your categories by Resources, you can use a @EVAL - binding to get the input-options for the listbox.
On the Frontend you could use getResources for listing the categories and inside the getResources-Tpl you can use a getImageList-call to get the by category(resource-id) filtered MIGX-items.

Of course its also possible to have an outer MIGX-TV for the categories and an inner MIGX-TV for the question/answers.
But drag/drop between categories isn't possible this way.

Thanks @Bruno17 for your quick response!

I didn't think about the possibility to use the @EVAL binding to retrieve the categories, this is definitely an option.

I would however prefer to keep everything in just one resource if possible, as I think this makes more sense to my clients when they edit the content. Are you able to explain the basics of how I would go about setting up an outer and an inner MIGX TV?

It works brilliantly, thank you so much! I'm sure this will come in handy in other situations too.

One last question - on my resource on the TV tab, under FAQs, before you click the category to edit it, it says [{MIGX_id":"1","question".... etc. etc. Is there any way of hiding this column so admins don't need to see it? Apart from scaring some admins I'm worried it's gonna get really long once you get a few FAQs in there.

In Columns, you don't need to have all fields, you just need



as the only one column in your grid

Of course, got it. Thank you so much for your help! I think I'm finally starting to get my head around MIGX now, after a few years of using it

PS. Love MIGX btw – MODX wouldn't be the same without it!

While we're at it... I'm trying to sort alphabetically by the question like this:



It works fine in my local development environment with PHP 5.4.10, but when I upload to my client's site with PHP 5.3.3 I get this error:

Warning: Parameter 2 to array_multisort() expected to be a reference, value given in /....../core/components/migx/model/migx/migx.class.php on line 1257

I posted in this thread where someone else has the same issue: https://forums.modx.com/thread/77554/how-to-proper-use-sort#dis-post-485078

Hi Sketchi

Can I ask how you got your actual FAQs to display?

I have a getImageList call as follows



and inside that I have:



It sucessfully displays the Categories in H3 headings but no actual questions and answers are displayed.

I suppose I need to know what actually goes in the chunk called


Thanks for your help

what do you get with:



you need to use this placeholders in the tplFAQ:



if you have this fields in your formtabs for the inner MIGX
