Question

I am trying to get result using below query, idRegion is recorded in database as 1,2,3,4 for each franchisee, so what I want is to display all franchisees with idRegion 2. I am getting idRegion via $_Get. this display only first digit before coma, I think so it should ready whole string 1,2,3,4 ? When I am working with static values that works?

$colname_franchisee = "-1";
if (isset($_GET['id'])) {
  $colname_franchisee = $_GET['id'];
}


$query_franchisee = sprintf("SELECT * FROM franchise WHERE stiShowInLinks = 'Y' AND idRegion LIKE '%s%' ORDER BY stiName ASC", $colname_franchisee);

Answer 1

This should work although I do not like your database design:

$query_franchisee = sprintf("
    SELECT *
    FROM franchise
    WHERE
    stiShowInLinks = 'Y' AND (
        idRegion = '%d' OR
        idRegion LIKE '%d,%%' OR
        idRegion LIKE '%%,%d' OR
        idRegion LIKE '%%,%d,%%'
    )
    ORDER BY stiName ASC
",
$colname_franchisee,
$colname_franchisee,
$colname_franchisee,
$colname_franchisee
);

The sprintf function treats the % character as a format specifier and treats at the next few characters in a special way. In order to use the % character literally, you must use %%. So after sprintf, your query becomes:

idRegion = '1234' OR
idRegion LIKE '1234,%' OR
idRegion LIKE '%,1234' OR
idRegion LIKE '%,1234,%'
