@hube2 You were right – my empty fields were returning false. I was able to use your method of validating with some slight tweaks to work for my specific case.
Here’s the solution that ended up working for me:
$instructors_total = 0;
$instructors = get_field('instructors');
if (is_array($instructors)) {
$instructors_total = count($instructors);
}
$leaders_total = 0;
$leaders = get_field('leaders');
if (is_array($leaders)) {
$leaders_total = count($leaders);
}
$designers_total = 0;
$designers = get_field('designers');
if (is_array($designers)) {
$designers_total = count($designers);
}
$speakers_total = 0;
$speakers = get_field('speakers');
if (is_array($speakers)) {
$speakers_total = count($speakers);
}
$staff_total = $instructors_total + $leaders_total + $designers_total + $speakers_total;
This is based on both of @hube2’s recommendations except that I’m using count() inside my is_array() validations rather than outside of them. Using count() to add the totals together outside the validation was returning a ‘1’ even if the array was empty. So if all of my arrays were empty, I was still getting ‘4’. I’m not entirely sure why.
There might be a better way to do this, but this is working well for me.
Thanks again @hube2!
@hube2 Thanks for your response. I tried your solution, but it doesn’t seem to be working. I used print_r() to see what value I was getting and it’s giving me the number of arrays (4) rather than the total number of objects in the 4 arrays. It’s very strange since I’m able to get the correct number if I use count() on an individual post object.
