How to conditionally enclose a list of reviews with `reverse_related_entries`?

Question

If there are review entries related to the current entry then I would like to display it as follows:

<aside id="reviews">
    <h3>Reviews</h3>
{reverse_related_entries channel="review"}
    <article>
        <h4>{title}</h4>
        {review_body}
    </article>
{/reverse_related_entries}
</aside>

If there are no reviews then I do not want to display anything.

I could just add a JavaScript which removes the empty "Reviews" section, but I would rather it wasn't outputted if possible.

Answer 1

Wouldn't this work?

{reverse_related_entries channel="review"}
{if count == "1"}
<aside id="reviews">
<h3>Reviews</h3>
{/if}
<article>
    <h4>{title}</h4>
    {review_body}
</article>
{if count == total_results}</aside>{/if}
{/reverse_related_entries}

Answer 2

Do you know off the top of your head if {if count % 4 == 0} works

I'd never considered the EE could use modulus. I haven't tested but a quick look at the docs and it isn't listed: http://ellislab.com/expressionengine/user-guide/templates/globals/conditionals.html#comparison-operators

I've done this many time by just enabling PHP for the template.
