Pro search {pro_search_distance} can't return 0

[robinsowell]

EE 7.2.13

The {pro_search_distance} should show the distance from the 'to' lat/longitude parameter, and it works UNLESS the distance is 0. Then it just is empty. I couldn't get it to output 0 no matter how I futzed around with it, including just hard coding '0' in the code.

I'm not sure how to fix, but it's definitely a bit confusing. And at some point in the past, it did work.

Example template:

{exp:pro_search:form query="{segment_3}" result_page="home/search"}

  {!-- The user’s lat/long values --}
  <input type="hidden" name="distance:from" value="52.163298|4.505547">
  
  <input type="text" name="distance:radius" value="100">


  <button type="submit">Go</button>
{/exp:pro_search:form}

{exp:pro_search:results
  query="{segment_3}"
  distance:to="local_lat|local_long"
  distance:unit="km"
}
  <p>{title} is {pro_search_distance}km away.</p>
  {if no_results}
    <p>Sorry, nothing found within a {pro_search_distance:radius}km radius.</p>
  {/if}
{/exp:pro_search:results}

I had 2 custom fields local_lat and local_long - local_lat 52.163298 local_long 4.505543 is so close, rounded it comes to 0 and just doesn't display anything for that variable.

This appears to be an issue with the parser in general, not Pro Variables in particular. Elvis can be dangerous!

(when you're using Elvis operand ?: and not checking for variable type - PHP would evaluate float(0) or even string("0") as false. TL, DR: don't use Elvis if you're working with mixed data type)
