$query = $dbh->prepare($sql);
$query->bindParam(':uin',$uin,PDO::PARAM_STR);
$query->bindParam(':fname',$fname,PDO::PARAM_STR);
$query->bindParam(':lname',$lname,PDO::PARAM_STR);
$query->bindParam(':email',$email,PDO::PARAM_STR);
$query->bindParam(':department',$department,PDO::PARAM_STR);
$query->bindParam(':recoffr',$recoffr,PDO::PARAM_STR);
$query->bindParam(':mobileno',$mobileno,PDO::PARAM_STR);
$query->execute();
$msg="Employee record updated Successfully";

Answer 1

You have the problem in the last parameter after where in your query. You're using eid parameter in your query while binding parameter you are using uin .

Update your this line of code.

$query->bindParam(':uin',$uin,PDO::PARAM_STR);

To this:

$query->bindParam(':eid',$uin,PDO::PARAM_STR);

Moreover your not using $eid variable anywhere in your code here.
