Answered Calling Migx TVs of a child resource

Apologies if this has been covered elsewhere but I can't track down a workable answer.

I've trying to grab content from a Migx TV of a child resource and display the value but 'am unable to get this working.

Calling the TV as standard displays the correct JSON output but I'm unable to find a method to parse that correctly.

getImageList produces no results when trying to call a for a child and the snippet code from https://forums.modx.com/thread/76012/how-to-get-the-migx-output-array-into-a-snippet-with-runsnippet#dis-post-421167 gives me a php error.

Any pointers would be most welcome.

Ah! So simple, how did I miss that? I'd omitted the &docid.

Many thanks for the prompt answer.

NB: Got it working...just needed to change the [[+id]] to [[*id]] because the call is in a Template. That one always gets me:-/


Hi,

I'm having a similar issue but i want to grab the MIGx tv from all child resources. I'm using Articles and have an imageTv in each of the articles. I can get this to work when i actually hardcode the ID but not when i add [[+id]], so i know that MIGx is working.

So this works, where `22` is the id of one of my child articles:


But this does not work:


The article container has an id of `21` and i want all the child docs of this container to be displayed. Do i need to use getResources?

Thanks for any help

you can try it cached:

I sorted it Bruno. it was my incorrect syntax as i'm using the call in a template so it should be [[*id]] instead of [[+id]]. I've updated my post above.
Thanks for your reply though all the same.

if you are calling the MIGX-TV of the current resource you don't need the property &docid.
getImageList uses the id of the current resource by default.
