Search on Multiple Columns
I have a form that contains;
$_POST['filterbrand'], $_POST['filtersize'], $_POST['minprice'], $_POST['maxprice']
This form lets the user choose which fields they wish to complete (NOT all required)
How do I configure the MySQLi extension dialogue with an SQL that allows for any or all of the form fields to be submitted and still provide a filtered result based on the information they did provide?
