数据库更新的 PHP 查询执行成功但值未在数据库表上更新

Question

我正在通过从 html 表单中获取数据来更新客户详细信息。数据库的 PHP 查询正在执行，但更改的数据未反射(reflect)在我的数据库表中。

PHP代码:

从表单中获取数据的代码

$con = mysqli_connect("localhost","root","","ecommerce");
    if(isset($_POST['savec']))
    {
        global $con;

        $name=$_POST['name'];
        $phone=$_POST['phone'];
        $email=$_POST['email'];
        $passm=$_POST['password'];
        $pass=md5($passm);
        $cust_query="UPDATE er_customer SET customer_name='$name',customer_phone='$phone',customer_email='$email',customer_password='$pass' WHERE customer_id='c_id'";
        $excecute=mysqli_query($con,$cust_query);

        if($excecute)
        {
            echo "<script> alert('Account changes is successfull.') </script>";
        }
    }

表单代码:

>    <form method="post" class="registration-form"
> action="account_settings.php" id="form_login"
> enctype="multipart/form-data">
>

尝试像这样更改您的更新查询:

$cust_query="UPDATE er_customer SET customer_name=$name,customer_phone=$phone,customer_email=$email,customer_password=$pass WHERE customer_id=$c_id";

通过调试所有变量值确保您获得正确
