update mysql database with form php $stmt

I'm having issues with updating my MySQL database with form inputs. I believe its an issue with the ID or something, but I am unsure.

Here is the full document:



$_SESSION["message"] = '<p class="message">Client updated successfully!</div>';

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ssl";
$dbh = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);


<!DOCTYPE html>
<meta charset="UTF-8">

$stmt = $dbh->prepare('select id, firstname, lastname, username, password, email, phone from users');
$result = $stmt->fetchall(PDO::FETCH_ASSOC);
foreach ($result as $row) {
echo '<div class="employee-inner">';
echo '<div class="employee">';
echo '<h3>ID</h3>' . '<p>' . $row['id'] . '</p>';
echo '<div class="clear"></div>';
echo '</div>';
echo '<form enctype="multipart/form-data" action="updateclients.php" method="POST">';
echo '<input class="update" type="text" name="firstname" placeholder=' . $row['firstname'] . ' required />';
echo "<br />";

$encrypted = md5("encrypted".$password);
$stmt = $dbh->prepare("update users set firstname='" . $firstname . "', lastname='" . $lastname . "', username='" . $username . "'. password='" . $password . "', email='" . $email . "', phone='" . $phone . "' values (:firstname, :lastname, :username, :encrypted, :email, :phone);");
$stmt->bindParam(':firstname', $firstname);
$stmt->bindParam(':lastname', $lastname);
$stmt->bindParam(':username', $username);
$stmt->bindParam(':encrypted', $encrypted);
$stmt->bindParam(':email', $email);
$stmt->bindParam(':phone', $phone);
echo '<p class="message">Client updated successfully!</p>';

Any information will help. Thanks and I appreciate it. There are no PHP errors, but it doesn't update the database.

You have bits of both UPDATE and INSERT syntax in your statement. It should just be:

$stmt = $dbh->prepare("update users set firstname=:firstname, lastname=:lastname, username=:username, password=:password, email=:email, phone=:phone
                        where id = :id");

You need to bind an additional parameter:

$stmt->bindParam(':id', $id);

Another problem is that your form uses method="POST". That means all the parameters will be in $_POST, not $_GET, so change all those variables.
