So, I ended up doing this:
<?php if( have_rows('section_content') ):
$rows = array();
$i = 0;
while ( have_rows('section_content') ):
the_row();
$rows[$i] = get_sub_field('content_option');
$i++;
endwhile;
$i = mt_rand(0,count($rows)-1);
echo $rows[$i];
else:
// some other stuff
endif; ?>
Hackfest 2015! But at least I’m getting the results I need. I’m guessing this isn’t very efficient, but I’m going to end up putting caching on this, and we’re talking about a very small audience (maybe 1000 visitors per month across 6 sites). So I think it will end up working out fine.
Still, I would love it if there’s a more native way to do what I’m doing, where I just pull one result, instead of pulling all of them and then selecting one from an array. It feels dirty…
