Question

我有一个表单，我从数据库中获取数据，现在我想更新数据库。问题是，当我更新表单中的内容并按更新按钮时，它表示记录已成功更新但数据库未更新。这是我的代码

<?php

session_start();

    $host="localhost";
    $user="root";
    $pass="";
    $db="documentation";


    $conn=mysqli_connect($host,$user,$pass,$db);
    $off=$_GET['id'];
    $result = mysqli_query($conn,"SELECT * FROM article WHERE id='". $off ."'");

if (isset($_POST['submitt']))
{

    $f1 = $_POST['f1'];
    $f2 = $_POST['f2'];
    $f3 = $_POST['f3'];
    $f4 = $_POST['f4'];


    $sql= mysqli_query($conn, "UPDATE article SET sub_name='" . mysqli_real_escape_string($conn,$f2) . "', article_name='" . mysqli_real_escape_string($conn,$f3) . "', art_description='" . mysqli_real_escape_string($conn,$f4) . "', useremailll='". $_SESSION["user_mail"] ."', dateposted= NOW() WHERE id='" . mysqli_real_escape_string($conn,$f1) . "'");

    if ($sql) {
        echo "Record updated successfully";
        header('index.php');

    } else {
        echo "Error updating record: " . mysqli_error($conn);
    }


}

Answer 1

我认为你错误地传递了id

尝试编辑此行

<input name='f1' value='". $id ."' type='hidden'/>

到

 <input name='f1' value='".$row['id']."' type='hidden'/>
