loop inside of loop?

Woo, let me see.. Something like this should work:

[loop type=projects fields=id]
  Project: [field title]
  [-loop type=tasks field=project_name value={ID}]
    Task: [field title]
  [/-loop]
[/loop]

It’s using “field tags”, which are described at the bottom of the documentation page for loop. I pass each project’s post ID to the inner loop, to look for tasks whose field project_name contains that project’s ID. Hopefully that field is stored as post ID.

Right now, there’s not a way to number them like 1, 1.1, 1.2, 2, 2.1, 2.2.. It’s possible to number projects using [loop-count], but not the inner loop of tasks. If you really need them numbered like that, I can see how to solve it.

The formatting probably needs some work to get it to display how you want.

If post content auto-formatting is adding <p> and <br> tags, you can go to Settings and enable [raw] shortcode, then wrap the whole code block like:

[raw]
  ..
[/raw]

I see, so the issue is not in the formatting.

Could you see if the field project_name is being saved as post ID? You could check in ACF field group setting, or maybe by outputting the value: [field project_name].

You could also check if the project’s post ID is being passed correctly:

[loop type=projects fields=id]
  Project: [field title] - {ID}
  ..
[/loop]

I wonder why it works with project 1, but not project 2. Have you tried, if it exists, a third project to see how that works or not?

I just made a new update to address the issue with [raw].

Hmm..could you try a fourth one? If that works, then we can narrow it down to only project 2.

I wonder if the right IDs are being passed. Could you tell me if the following shows different post IDs?

[loop type=projects fields=id]
  Project: [field title] - {ID}
[/loop]

Another angle – can you see what the following does? Where it says “1,2,3” if you could put the project post IDs.

[loop type=tasks field=project_name value=1,2,3]
  Task: [field title]
[/loop]

OK, I think I found the issue – it was related to nested loops and how their internal state was being handled. Could you try the latest version and see if it works now?
