Question

我已经在Godaddy上传了一个登录/注册网站，因为某些原因页面无法正确重定向，并且可以在本地主机上进行正常测试，任何帮助都将不胜感激！

这是我的register.php页面的代码：

<!doctype html>
<html lang="en">
<head>
<title>Register page</title>
<meta charset=utf-8>
<link rel="stylesheet" type="text/css" href="includes.css">
<style type="text/css">
p.error { color:red; font-size:105%; font-weight:bold; text-align:center;}
</style>
</head>
<body>
<div id="container">
<?php include("register-header.php"); ?>
<?php include("nav.php"); ?>
<?php include("info-col.php"); ?>
    <div id="content"><!-- Start of the register page content -->
<p><?php
require ('mysqli_connect.php'); // Connect to the database.
// If the form has been submitted, insert a record in the users table
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $errors = array(); // Initialize an error array
    // Check for a first name:
    if (empty($_POST['fname'])) {
        $errors[] = 'You forgot to enter your first name.';
    } else {
        //$fn = trim($_POST['fname']);
            $fn = mysqli_real_escape_string($dbcon, trim($_POST['fname']));
    }
    // Check for a last name:
    if (empty($_POST['lname'])) {
        $errors[] = 'You forgot to enter your last name.';
    } else {
        //$ln = trim($_POST['lname']);
        //$ln = mysqli_real_escape_string($dbcon, $ln);
        $ln = mysqli_real_escape_string($dbcon, trim($_POST['lname']));
    }
    // Check for an email address
    if (empty($_POST['email'])) {
        $errors[] = 'You forgot to enter your email address.';
    } else {
        $e = trim($_POST['email']);
    }
    // Check for a password then match it against the confirmed password:
    if (!empty($_POST['psword1'])) {
        if ($_POST['psword1'] != $_POST['psword2']) {
            $errors[] = 'Your two password did not match.';
        } else {
            $p = mysqli_real_escape_string($dbcon, trim($_POST['psword1']));
        }
    } else {
        $errors[] = 'You forgot to enter your password.';
    }
    if (empty($errors)) { // If everything's OK
    // Register the user in the database...
        // Make the query:
        $q = "INSERT INTO users (user_id, fname, lname, email, psword, registration_date) VALUES (' ', '$fn', '$ln', '$e', SHA1('$p'), NOW() )";        
        $result = @mysqli_query ($dbcon, $q); // Run the query.
        if ($result) { // If it ran OK
        header ("location: register-thanks.php"); 
        exit();
        // Echo a message:
        //echo '<h2>Thank you!</h2>
        //<p>You are now registered.</p><p><br></p>';   
        } else { // If it did not run OK

Answer 1

您在header()来电之前有输出。之前必须绝对没有输出。如果您启用错误报告，则可能会看到有关＆＃34;已发送标题的警告＆＃34;。

将您的登录代码移至页面的绝对开头，存储所有消息以供日后显示。

页面不会重定向到正确的页面
