Custom Looper Provider with nested WP Objects

[Regnalf]

I would like to create a custom provider that can loop to a certain custom post type and in turn can contain custom WordPress Objects to loop over.

Here is an overview to better understand what I already have:
An Array of WordPress Objects for Campaigns that contain other WordPress Objects to the events in their own Array. (Of Course there are more Campaign Objects)

array (0) WP Object
  'id' = 1234
  'title' = campaign
  ....
  'subloop' array (0) WP Object
              'id' = 1235
              'title' = 'event #1'
              ...
            array (1) WP Object
              'id' = 1236
              'title' = 'event #2'
              ....

I just expanded the found WordPress objects with the ‘subloop’ array, that will show me with the debug-consumer correctly.

But when I want to run a custom provider over this subloop array, I don’t get any data.
Structure of the looper provider and consumer:

section [custom looper provider = campaign]
- row [looper consumer]  (Works as it should)
-- column (Campaign Info)
     "title campaign"
-- column [array looper provider = looper field "subloop"]  (Doesn't work)
---- Output event [looper consumer]
     "title event"

Is it because i use nested WordPress Post Objects?

Hello @Regnalf,

Thanks for writing in! Nested Looper Provider should work in the theme. What are the Looper Providers that you used?

I’ve updated secure note.

As i wrote in my initial post, i use first a custom provider for the main loop, and then use an array provider for the sub field, in my case it is the field [‘proben’].

Hello @Regnalf,

I can see that you are using this alle_proben as your Looper Provider Custom.

I could not find the code in your child theme’s functions.php file. Where did you place this custom Looper Provider code?

Thanks.

[Regnalf]

That’s right, this page uses a lot of self-made code. That’s why I put it in a separate php file. See the secure note.

Hi @Regnalf,

I have checked your code and it seems that key in the dynamic content tag {{dc:looper:field key=“proben”}} is missing in the response. If the proben key is not present in the response, it will not show in the dynamic content. If that is a post meta field, you need to add it into the response separately.

Thanks

[Regnalf]

What do you mean it’s not there, you can see it already in the debug-consumer output!

It’s an array with the sub WP_Post Objects! It’s not an meta key it’s self generated.

Main Looper:

Sub Looper

It’s still a development site, so you can use the credentials as given in the SN.

Hello @Regnalf,

We have investigated your issue and we found out that what you are trying to do is beyond the limits of the Looper provider feature built-in the theme. There does seem to be some misconceptions on how the different looper types work though, so here are some things that may help:

• The Looper Provider Array type expects a string key like “name” and will grab that field from the current looper item. The value there shouldn’t contain Dynamic Content
• If the looper consumer is a PHP object instead of an array, the values won’t be accessible via {{dc:looper:field}}
• If contents of the Looper Consumer are a WordPress Post object, it should be available using the normal Post statements like {{dc:post:title}}

Hope this helps.

I already thought that it has something to do with the WP object. But I wanted to try it anyway, because the provider has displayed it correctly.

Anyway, plan B. I will do it either with a second own provider or with a query string.

Thanks @ruenel, and maybe you could add it to the bottom of the wishlist.

You are most welcome. Yes, I will forwarded this to our developer.
