Question

当我在管理面板中更新任何内容并单击更新按钮时，没有任何反应 - 即它既不会更新也不会转到我们单击编辑的页面。我正在使用免费托管。相同的代码正在本地主机上工作，但它不能用于免费托管。任何人都可以帮助我吗？

$sqlN="UPDATE selectplan SET plan_name='$planname',Plandetails='$Plandetails', Plantime='$Plantime', Plandate='$Plandate', plancost='$plancost', img='$image' WHERE id='$id__' ;";
$resultN=mysqli_query($conn,$sqlN);

这是完整的代码

<?php
require "conn.php";

session_start();

if(!isset($_SESSION['id']))
{
    header('Location:index.php');
}   
else
{
    $id__=$_GET['id'];

    $sql="SELECT * from selectplan where id='$id__' ;";

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

    if((mysqli_num_rows($result))>0)
    {
        $row=mysqli_fetch_row($result);
        $id_P=$row[0]; //id
        $planname=$row[1];//name
        $Plandetails=$row[2];
        $Plantime=$row[3];
        $Plandate=$row[4];
        $plancost=$row[5];
        $img__=$row[6];
    }
}
if (isset($_POST['submit'])) 
{
    $planname=$_POST["planname"];//name
    $Plandetails=$_POST["Plandetails"];
    $Plantime=$_POST["Plantime"];
    $Plandate=$_POST["Plandate"];
    $plancost=$_POST["plancost"];
    if($planname==""||$Plandetails==""||$Plantime==""||$Plandate==""||$plancost=="")
    {
        echo "Please fill in all the fields";
    }
    else
    {
        $target="images/".basename($_FILES['image']['name'] );

        //get all the submitted data from the form
        $image=$_FILES['image']['name'];

        //now move upload image to folder
        if (move_uploaded_file($_FILES['image']['tmp_name'], $target))
        {
            echo "image upload";
        }
        $sqlN="UPDATE selectplan SET plan_name='$planname',Plandetails='$Plandetails', Plantime='$Plantime', Plandate='$Plandate', plancost='$plancost', img='$image' WHERE id='$id__' ;";
        $resultN=mysqli_query($conn,$sqlN);
        if ($resultN) {
            header('Location:profile.php');
        }
    }
}

我认为您的问题出在conn.php中您的身份验证值不正确在conn.php中，yku应该更改当前localhost的值并更改用户并传递

PHP / MySql更新查询不起作用
