Question

I have this Error: Fatal error: Uncaught Error: Cannot use object of type PDOStatement as array in C:\xampp\htdocs\seth\Plugins\login\php\completedetails.php:28 Stack trace: #0 {main} thrown in C:\xampp\htdocs\seth\Plugins\login\php\completedetails.php on line 28

it some days ago was functiones but now it pass, ¿what I should do?, Im leaving the code down

session_start();

$_SESSION['id'];
$id = $_SESSION['id'];
$name = $_POST['name'];
$password = $_POST['password'];
$password = password_hash($password, PASSWORD_DEFAULT); 
$team = $_POST['team'];


    if($name == "" && $password == "" && $team == ""){
        return false;
    }

    else {
    require './conectar.php';
    $resultset = $conn->prepare("SELECT * FROM users WHERE id = '$id' LIMIT 1");
    $resultset->execute();
    $resultkey = $resultset->fetch();

    if($resultkey !== false) {

        $update = "UPDATE users SET name = :name, password = '$password' WHERE id = '$id' LIMIT 1";
        $up = $conn->prepare($update);
        $up->bindParam(':name', $_POST['name'], FILTER_SANITIZE_SPECIAL_CHARS);
        $up->execute();
        $_SESSION['name'] = $up['name'];

    }

}

Answer 1

You need to first fetch the result of your query:

$up = $conn->prepare($update);
$up->bindParam(':name', $_POST['name'], FILTER_SANITIZE_SPECIAL_CHARS);
$up->execute();
$result = $up->fetch();
$_SESSION['name'] = $result['name'];

The fetch method in your framework might return an object instead of an array. In that case you can access the name property like this:

$result->name;

Either way, you can't use $up to get the name because, as your error says, it's an object of type PDOStatement and not actually the result of the query.
