Question

I have this code

$marker = 'werkz';
$sql = "SELECT name, marker FROM sidebar";
$q = $db->query($sql);
$q->setFetchMode(PDO::FETCH_ASSOC);
while ($r = $q->fetch()) {
    echo'<option>' . $r[name] . '</option>';
    }

It works but when I add WHERE marker = $maker; the query fails.

What is the problem?

Answer 1

since you are using PDO, do it like this when passing parameter.

$marker = 'werkz';
$sql = "SELECT name, marker FROM sidebar WHERE marker = ?";
$q = $db->query($sql);
$q->bindParam(1, $maker);
$q->setFetchMode(PDO::FETCH_ASSOC);
while ($r = $q->fetch()) {
    echo'<option>' . $r[name] . '</option>';
}
