Loop inside of a loop. Don't show item from first loop if no posts in inside loop

Loops & Logic
#1

So I have two Loops. First loop is a Taxonomy loop (States), and inside that is a Loop (Store) for all locations inside that State (but only if they match another taxonomy - Rewards).

<Loop type=taxonomy_term taxonomy=location_state>
    <h2><Field title /></h2>
    <Loop type=store taxonomy=rewards terms="{Field id}">
        <a href="{Field url}"><Field title /></a>
    </Loop>
</Loop>

But sometimes there are no items inside the second loop because not all Stores have Rewards enabled.

So how can I remove the <h2> if its loop below it doesn’t have any results?

I’m assuming an <If> statement of some kind but can’t quite figure out how to do it for something that lives outside of the loop you’d be checking in…

#2

I kinda thought I would be able to do something like this:

<Loop type=taxonomy_term taxonomy=location_state>
    <If loop exists type=store taxonomy=rewards terms="{Field id}">
        <h2><Field title /></h2>
        <Loop type=store taxonomy=rewards terms="{Field id}">
            <a href="{Field url}"><Field title /></a>
        </Loop>
    </If>
</Loop>

But that didn’t work - it output nothing

#4

And if I do this, it outputs nothing:

<Loop type=taxonomy_term taxonomy=location_state>
    <If loop exists type=store taxonomy=rewards terms="{Field id}">
        <h2><Field title /></h2>
        <Loop>
            <a href="{Field url}"><Field title /></a>
        </Loop>
    </If>
</Loop>

And if I do this like the documentation says I should, then it just outputs every post under every State:

<Loop type=taxonomy_term taxonomy=location_state>
    <If loop exists type=store taxonomy=rewards>
        <h2><Field title /></h2>
        <Loop terms="{Field id}">
            <a href="{Field url}"><Field title /></a>
        </Loop>
    </If>
</Loop>
#5

That would maybe lead me to believe it is a bug that this doesn’t work?

<If loop exists type=store taxonomy=rewards terms="{Field id}">

This is another option to test to:

<If loop exists type=stores taxonomy=rewards parent="{Field id}">

#6

Hmm… So I just realized that this from the beginning doesn’t work… So I for sure need to get that to work first before testing anything else

<Loop type=taxonomy_term taxonomy=location_state>
    <h2><Field title /></h2>
    <Loop type=store taxonomy=rewards terms="{Field id}">
        <a href="{Field url}"><Field title /></a>
    </Loop>
</Loop>

This DOES work (below), so idk why changing the taxonomy on the inner Loop (in my example above) doesn’t work?

<Loop type=taxonomy_term taxonomy=location_state>
    <h2><Field title /></h2>
    <Loop type=store taxonomy=location_state terms="{Field id}">
        <a href="{Field url}"><Field title /></a>
    </Loop>
</Loop>

I’m going to open up a separate thread to discuss this part first: Taxonomy loop with post loop inside (but pulling another taxonomy)?

#7

So with the basics addressed in your separate post, the solution to hide the heading if there are no matching items in the loop looks like this:

<Loop type=taxonomy_term taxonomy=location_state>
  <If loop type=store taxonomy=location_state terms="{Field id}" taxonomy_2=rewards taxonomy_compare_2=exists terms_2="">
    <h2><Field title /></h2>
    <Loop type=store taxonomy=location_state terms="{Field id}" taxonomy_2=rewards taxonomy_compare_2=exists terms_2="">
        <a href="{Field url}"><Field title /></a>
    </Loop>
  </If>
</Loop>

Perfect. Thank you so much
