Array zur String-Konvertierung $ query. = "Image = '{$ image}'"; -------------------------------------------------- -------------------------------------------------- --------------------------------

if (isset($_POST['submit'])) { 

    $file = rand(1000,100000)."-".$_FILES['image']['name']; 
    $file_loc = $_FILES['image']['tmp_name']; 
    $folder="uploads/"; 

    $new_file_name = strtolower($file); 
    $image =str_replace(' ','-',$new_file_name); 
    move_uploaded_file($file_loc,$folder.$image); 

    $firstname  = $_POST["firstname"]; 
    $lastname  = $_POST["lastname"]; 
    $address1  = $_POST["address1"]; 
    $address2  = $_POST["address2"]; 
    $city   = $_POST["city"];

    $passwordold = $_POST["oldpassword"]; 
    $passwordone = $_POST["passwordone"]; 
    $passwordtwo = $_POST["passwordtwo"]; 
    $sessions  = $_SESSION['admin_id']; 


    $query = "UPDATE user SET ";

$ _FILES ["Bild"] ist ein Array. Sie können String nur in SQL-Abfragen übergeben. Möglicherweise müssen Sie das Array serialisieren und dann in der Datenbank speichern.
