Question

我正在尝试使用sql查询编辑记录，但它只允许我编辑一条记录。我尝试更新projectname和projectnr。当我尝试更新两个记录时，它们都没有得到更新。每当我尝试更新projectname时，它允许我更改它。当我单独尝试那个时，Projectnr不会更新。

            include("dbconfig.php");
            // $connection = mysql_connect('localhost', 'root', '');
            // mysql_select_db('projectsync');

            if( isset($_GET['edit']))
            {
                $id = $_GET['edit'];

                /*$result = mysql_query("SELECT * FROM projecten WHERE projectnr='$id'");

                while($rows = mysql_fetch_array($result)){
                    $projectnr= $rows['projectnr'];
                    $projectnaam= $rows['projectnaam'];
                } */

                $query = "SELECT * FROM projecten WHERE projectnr='$id'";
                $projecten = $conn->prepare($query);

                try {
                    $projecten->execute(array());
                    $projecten->setFetchMode(PDO::FETCH_ASSOC);

                    foreach($projecten as $project){
                        $projectnr = $project['projectnr'];
                        // $email = $consultant['email'];
                        // $admin = $consultant['admin'];
                        $projectnaam = $project['projectnaam'];
                    }
                }
                catch(PDOException $e){
                echo "<script>$('Er iets is misgegaan, wilt u opnieuw proberen alstublieft!');</script>";
                }

                //$rows = mysql_fetch_array($result);

                //$res = $conn->prepare("SELECT * FROM klant WHERE klantnr='$id'");
                //$row = $res->fetch(PDO::FETCH_ASSOC);
            }

            if( isset($_POST['newProject']))
            {
                $newProject = $_POST['newProject'];
                $id    = $_POST['projectnr'];

                /*$sql = "UPDATE klant SET naam='$newUsername', admin= '$newAdmin', password= '$newPass', username= '$newName' 
                WHERE klantnr='$id'";

                $row= mysql_fetch_array($res);
                $res   = mysql_query($sql)
                                            or die("Could not update".mysql_error());
                */

                try {
                    $query = "UPDATE projecten SET projectnaam='$newProject' WHERE projectnr='$id'";
                    $data = $conn->prepare($query);
                    $data->execute();
                    $row = $data->fetch(PDO::FETCH_ASSOC);
                }
                catch(PDOException $e) {
                    echo $e->getMessage();
                }
            }

            if(isset($_GET['delete']))
            {
                $id = $_GET['delete'];
                //$res= mysql_query("SELECT * FROM klant WHERE klantnr='$id'");
                //$row= mysql_fetch_array($res);

                $res = $conn->prepare("SELECT * FROM klant WHERE klantnr='$id'");
                $row = $res->fetch(PDO::FETCH_ASSOC);

                    include("dbconfig.php");

                    $sql = "DELETE FROM klant WHERE klantnr='$id'";

                    $conn->exec($sql);
                    echo "<script>alert('User successfully deleted.');</script>";
                    header("refresh: 0.4; url=manage.php");
                }
                catch(PDOException $e) {
                    echo $sql . "<br />" . $e->getMessage();
                }
            }
