Question

I have this query:

$queryf = "SELECT * FROM classifieds 
WHERE city IN ('$cities') AND state IN ('$states') 
ORDER BY FIELD (city, '$cities'), datetime DESC";

$cities is an array of nearby cities within 5 miles. Same with states.

Basically, I want to search my user information table that has user-inputted information (like a craigslist/classifieds type table), and COUNT the number of rows PER CITY. So that it’s possible to echo something like:

10 results found within 5 miles:
Dublin, CA (8 records)
Hayward, CA (2 records)

Does anyone know how I’d be able to track/return the amount of rows where the city is identical?

Answer 1

A GROUP BY, together with COUNT() should give you what you need:

$queryf = "SELECT *, count(classifieds.id) AS num_cities FROM classifieds 
WHERE city IN ('$cities') AND state IN ('$states') 
GROUP BY city
ORDER BY FIELD (city, '$cities'), datetime DESC";
