Question

这是我的login.php代码:(这是显示表单的页面，要求用户输入6位代码。一旦输入正确的代码并按提交，用户将转到admin.php if代码是正确的

<?php
session_start();
include('connection.php');
?>
<!doctype html>
<html lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title></title>
    <link href="css/style.css" rel="stylesheet" type="text/css" />
    <link href="css/reset.css" rel="stylesheet" type="text/css" />
<div id="container">
<div id="authorise">
<form action="admin.php" method="POST" name="authorisation"><br>
<!--Product Comment Box--><br>
<p>Please enter your 4<br> digit authorisation code:<br> <br><input type="text" name="code"/></p><br>
<input type="submit" value="Log In"/>
</form>

<?php
if (isset($_POST['code']) && $_POST['code'] == '210392') {
    header("Location: https://www.google.co.uk");
    exit;
}
?>

</div>
</div>

这是我的admin.php文件（为复制整件事而道歉）

<!doctype html>
<html lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title></title>
    <link href="css/style.css" rel="stylesheet" type="text/css" />
    <link href="css/reset.css" rel="stylesheet" type="text/css" />
    <style type="text/css">
        table {
            font-family: verdana,arial,sans-serif;
            font-size:11px;
            color:#333333;
            border-width: 1px;
            border-color: #999999;
            border-collapse: collapse;
        }
        table th {
            background:#b5cfd2;
            border-width: 1px;
            padding: 8px;
            border-style: solid;
            border-color: #999999;
        }
        table td {
            background:#dcddc0;
            border-width: 1px;
            padding: 8px;
            border-style: solid;
            border-color: #999999;
        }
    </style>    
</head>

<body>
<div id="container4">
<div id="adminpanel">

<div id="showorders"><u>Orders</u></div>
<?php
include('connection.php');

$result = mysql_query("SELECT * FROM orderform");

echo "<table border='1' >

}
echo "</table>";

?>

<div id="showreviews"><u>Reviews</u></div>
<?php
include('connection.php');
$result = mysql_query("SELECT * FROM reviewform");

echo "<table border='1'>

while($row = mysql_fetch_array($result))
{

echo "<td>" . $row['name'] . "</td>";

echo "<td>" . $row['comment'] . "</td>";

echo "</tr>";
}
echo "</table>";

?>
</div>
</div>

这是有问题的两个文件。谢谢你的帮助。就像我之前说的那样，我是一个完整的新手

Answer 1

将其移至文件顶部：

if (isset($_POST['code']) && $_POST['code'] == '210392') {
    header("Location: https://www.google.co.uk");
    exit;
}

Answer 2

如果你这样做是不必要的，你不必检查它的设置。如果您自己检查代码就足够了：

if($_POST['code'] != 210392) {
    echo "https://www.google.co.uk";
}

顺便说一句，这不是你所做的错误。您遇到的问题不在此文件中，而是在admin.php移动上面的if条件，一切都应该可以正常工作，至少在我尝试时它对我有用。
