用於編輯存儲記錄不工作的空字段驗證

我已經連接到我的數據庫來編輯存儲的記錄，並且我已經使用變量來處理錯誤。用於編輯存儲記錄不工作的空字段驗證

當我嘗試用它重定向空字段提交，並顯示更改已保存，而不是顯示空字段消息

我敢肯定的消息有什麼不對我的環路的結構，我把有什麼地方在錯誤的地方？

<?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']; 
} 
?>

嘗試這個

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

奇怪。如果我爲史密斯姓氏並刪除它並單擊提交，字段值（在這種情況下史密斯）默認爲以前的值比保存的空記錄更好，但仍然沒有錯誤消息。 – Nullbreaker
