Question

I’ve written the below code to return a single value from the table but it doesn’t seem to be working. Any idea why?

$pmname = $pdo->quote($_SESSION['pmname']);
$sql = "SELECT img FROM pm_user WHERE name=$pmname";
$result = $pdo->query($sql);
foreach ($result as $row) 
{
echo $row["img"];
}

Why aren’t you fetch-ing anything? Try replaceing the foreach with:

while($row = $result->fetch(PDO::FETCH_ASSOC))
{
    echo $row['img'];
}

or even, if you’re sure there is but one single row:

$row = $pdo->query('your query')->fetch(PDO::FETCH_ASSOC);
echo $row['img'];

Could well do the trick, though I haven’t tried this – yet.
