Question

我已经连接到我的数据库来编辑存储的记录，我已经使用了一个变量来处理错误。

当我尝试使用空字段提交时，它会重定向并显示更改已保存的消息，而不是显示空字段消息

我确定我的循环结构有问题，而且我把东西放错了地方？

<?php
//session_start();
// connect to the database
include('connect.php');
$message = $_GET['message'];
// check if the form has been submitted then process it
if (isset($_POST['submit']))
{
// Get data from table
//set the id manually for test purposes
$id = "429";
$forename = $_POST['forename'];
$surname = $_POST['surname'];
$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];
// check for empty fields and display error message
if (empty($forename) &&!empty($surname) &&!empty($username) &&!empty ($password) &&!empty ($email))
{
$message = "Please enter data in all fields" ;
header("Location: edit.php?message=$message");
}
else
{
// save the data to the table
mysql_query("UPDATE registration SET forename='$forename', surname='$surname', username='$username', email='$email', password='$password' WHERE id='$id'")
or die(mysql_error()); 
}
// redirecr and display message
$message = "Your changes have been saved";
header("Location: edit.php?message=$message");
exit;
}
$id=429;// this line could have been $id=$_SESSION['id'];
$result = mysql_query("SELECT * FROM registration WHERE id=$id LIMIT 1")
or die(mysql_error()); 
$row = mysql_fetch_array($result);
// check that the 'id' matches up with a row in the databse
if($row)
{
// get data from the table
$forename = $row['forename'];
$surname = $row['surname'];
$username = $row['username'];
$email = $row['email'];
$password = $row['password'];
}
?>

Answer 1

试试这个

if (empty($forename) || empty($surname) || empty($username) || empty ($password) || empty ($email))
    {
    $message = "Please enter data in all fields" ;
    header("Location: edit.php?message=$message");
    }

用于编辑存储记录不起作用的空字段验证
