Question

我有一个问题，由于某种原因数据没有被更新。我尝试了多种方法，但似乎没有任何解决方法。知道为什么不更新数据吗？麻烦在下面发布我的所有代码。

编辑页面

<?php 
    require_once("config.php"); //this file connects to my db and works 100%
    $iD = $_GET['GetID'];
    $query = "SELECT * FROM db WHERE Id='".$iD."'";

    $result = mysqli_query($conn, $query);

    while($row=mysqli_fetch_assoc($result))
    {
        $id = $row['Id'];
        $name = $row['Name'];
        $date = $row['Birthdate'];
        $phonenumber = $row['PhoneNumber'];
        $sex = $row['Sex'];
        $weight = $row['Weight'];
        $height = $row['Height'];
        $emergencycontactname = $row['EmergencyContactName'];
        $emergencycontactnamephonenumber = $row['EmergencyContactNamePhoneNumber'];
        $medicalissues = $row["MedicalIssues"];
    }

?>

                            </div>
                </form>
    </body>
    </html>

在下面更新PHP代码

<?php

    require_once("config.php");

    if(isset($_POST['update']))
    {
        $id = $_GET['Id']; 
        $name = $_POST['Name'];
        $date = $_POST['Birthdate'];
        $phonenumber = $_POST['PhoneNumber'];
        $sex = $_POST['Sex'];
        $weight = $_POST['Weight'];
        $height = $_POST['Height'];
        $emergencycontactname = $_POST['EmergencyContactName'];
        $emergencycontactnamephonenumber = $_POST['EmergencyContactNamePhoneNumber'];
        $medicalissues = $_POST["MedicalIssues"];

        $query = "UPDATE db SET Name ='".$name."', Birthdate ='".$date."', PhoneNumber ='".$phonenumber."', Sex ='".$sex."', Weight ='".$weight."', Height ='".$height."', EmergencyContactName ='".$emergencycontactname."', EmergencyContactNamePhoneNumber ='".$emergencycontactnamephonenumber."', MedicalIssues ='".$medicalissues."' WHERE Id='".$id."'";

        $result = mysqli_query($conn,$query);

        if($result)
        {
            header("location:view.php"); //redirects me here but does not update data
        }
        else{
            echo "Please Check your query";
            echo "<br>";
            echo $query;
        }
    }
    else
    {
        header("location:view.php");
    }
?>

所以是的，我不确定它的查询是否错误，但是它只是将我重定向到我的view.php文件，并且我尝试了多种操作，例如更改重定向以查看哪个正在工作，并将其发送到包含变量结果的if语句。任何线索为什么它不起作用？我觉得查询是正确的。

数据未更新。我怎样才能解决这个问题？
