Question

UPDATE.php

<?php 
    include('DB.php');
    if(isset($_GET['id'])){
        $id=$_GET['id'];
        if(isset($_POST['update'])){
           $name=mysqli_real_escape_string($link,$_POST["ename"]);
           $email=mysqli_real_escape_string($link,$_POST["eemail"]); 
           $enpassword=mysqli_real_escape_string($link,$_POST["epassword"]);
           $dateofbirth=mysqli_real_escape_string($link,$_POST["edateofbirth"]);
           $mobile=mysqli_real_escape_string($link,$_POST["emobile"]);
           $presentaddress=mysqli_real_escape_string($link,$_POST["epresentaddress"] );
           $drivinglicense=mysqli_real_escape_string($link,$_POST["edrivinglicense"]);

           if(mysqli_query("UPDATE hrmsinfo SET emp_name=$name,emp_email=$email,emp_password=$enpassword,emp‌_dob=$dateofbirth,em‌p_phno=$mobile,emp_a‌ddress=$presentaddress,emp_proof=$drivin‌glicense WHERE emp_id='$id'")){
               $msg="Successfully Updated!!";
               header('Location:VIEW.php');
           }
           else{
               $msg="Unsucessfull!!";
           }
       }
    }  //update ends here
    ?>

当我尝试使用以下编辑代码执行此更新代码时，它显示空白页面帮助我

以下是完全执行的编辑代码，但更新不起作用，帮助我在哪里停留

<?php 

//error_reporting(0);
include("DB.php");
if(isset($_GET['id'])){
     $id=$_GET['id'];
     $sql="SELECT * FROM hrmsinfo WHERE emp_id='$id'";
     $sqll=mysqli_query($link,$sql);
     while($profile=mysqli_fetch_array($sqll)){
         $username=$profile['emp_name'];
         $usermail=$profile['emp_email'];
         $userdob=$profile['emp_dob'];
         $usermobile=$profile['emp_phno'];
         $useraddress=$profile['emp_address'];
         $userproof=$profile['emp_proof'];
?>

如果我被困在这里或者我犯了错误，请帮助我正确指导

Answer 1

根据你的代码，你提出了一个条件，即

if(isset($_GET['id']))
    {
     .....
}

但是在html表单中你没有传递任何id字段添加id字段并尝试你的条件将验证和更新将工作。只需添加一个字段，如下所示..剩余相同。

    <form action="UPDATE.php?id=<?php echo $id; ?>" method="post" name="insertform">
    <input type="hidden" name="id"  value="<?php echo $id; ?>" >
   ...............
.................
</form>

注意：在HTML页面中，字段ID应该是唯一的。

看到update.php时出现空白页或空白页
