Question

I can't seem to get the code for updating user information on my database to work. I followed a tutorial but I can't spot the error in the code. The retrieving of the information from the database works, and I am able to display that info on the page.

    grep -nr '/users/myname/Desktop/website' -e "gaq"
    grep -nrw '/users/myname/Desktop/website' -e "gaq"

My database is called register and my field names are id, firstname, lastname, password and email.

heres the code for my form too:

$user = $_SESSION['user_id'];   
$result = $con->query("SELECT * FROM register WHERE id ='$user'");
$row = $result->fetch_array(MYSQLI_BOTH);
    $_SESSION["firstname"] = $row['firstname'];
    $_SESSION["lastname"] = $row['lastname'];
    $_SESSION["email"] = $row['email'];
    $_SESSION["password"] = $row['password'];

if(isset($_POST['update'])){
    $updateFname = $_POST['fname']; 
    $updateLname = $_POST['lname']; 
    $updatEmail = $_POST['email'];  
    $updatePassword = $_POST['password'];   

    $sql = $con->query("UPDATE register SET firstname = '{$updateFname}', lastname = '{$updateLname}', email='{$updatEmail}', password='{$updatePassword}' WHERE id = $user");
    header('Location:account.php');
}`

Answer 1

I would add single quotes around the $user variable at the end of the update query.

Answer 2

I'm assuming you left out $conn = new mysqli($servername, $username, $password, $dbname); on purpose.

ctrl.item.value
