Answer 2

I am not sure what you want but try this:

PHP:

// mysql escape
$locations = array_map("mysql_real_escape_string", $_POST['location']);
// add locations to query string
$locations = implode("','",$location);

$query = "SELECT 
              name, type, description, location, zip_code, phone_number
              FROM search
              WHERE location IN ('$locations')
              ";
if (isset($_POST['type']) && !empty($_POST['type'])){
  $query .= " or type LIKE '%".mysql_real_escape_string($_POST['type'])."%'";
}
