我遵循Adam Khoury的"如何建立一个社交网络网站"教程，我在第6课，"注册表单和电子邮件激活PHP MySQL JavaScript编程教程"。
这里的教训和代码:http://www.developphp.com/view.php?tid=1294
完成这节课后，我有一个新的用户注册表单，但我遇到两个问题。
1。表单显示注册成功，它显示正确的确认消息"OK TestUser，请在whatever@gmail.com检查您的电子邮件收件箱和垃圾邮箱，通过激活您的帐户来完成注册过程。"您将无法在网站上做任何事情，直到您成功激活您的帐户。，但是用户的详细信息并没有被输入到user数据库表中。
2。确认邮件没有发送到用户的收件箱(或垃圾邮件)
我使用bluehost.com作为我的服务器，并且我已经在bluehost创建了适当的电子邮件地址(出于隐私原因，电子邮件地址在下面的代码中更改为"auto_responder@myserver.com")。
这是我的注册。php文件:<?php session_start();
// If user is logged in, header them away
if(isset($_SESSION["username"])){
header("location: message.php?msg=NO to that weenis");
exit();
}
?><?php if(isset($_POST["usernamecheck"])){
include_once("php_includes/db_conx.php");
$username = preg_replace('#[^a-z0-9]#i', '', $_POST['usernamecheck']);
$sql = "SELECT id FROM users WHERE username='$username' LIMIT 1";
$query = mysqli_query($db_conx, $sql);
$uname_check = mysqli_num_rows($query);
if (strlen($username) < 3 || strlen($username) > 16) {

你不应该依赖Adam Khoury的"如何建立一个社交网络"教程。
一半的代码是过时的，不可靠的。太多的SQL注入可以从该源完成。但是Ajax教程也非常好而且可靠。这是一个很好的开始方式，但不应该依赖它。
mysql_太过时了。我推荐使用PDO。
但是，这又是一个老问题。
我不确定你是否找到了答案，但我也遇到了这个问题。
1)确保电子邮件地址是正确的，否则你不会给他们发电子邮件。现在，实际名称不需要正确，但@Yourdomain.com需要。许多公司会输入一个虚假的电子邮件地址，通常是noreply@yourdomain.com，这个地址实际上没有收件箱，或者它确实存在，但没有人检查它。我个人添加了这个电子邮件地址，并没有打扰它，因为我宁愿用我的电子邮件槽做其他事情。只要澄清一下，使用我的方法，我从来没有遇到过垃圾邮件的问题，所有的邮件都进入了我的收件箱。
2)我的用户表没有写(但useroptions)，我把它归结为这样一个事实，在这段代码
// Add user info into the database table for the main site table
$sql = "INSERT INTO users (username, email, password, gender, country, ip, signup, lastlogin, notescheck)
VALUES('$u','$e','$p_hash','$g','$c','$ip',now(),now(),now())";
在最后它说now()这需要更改为now()并确保将所有now()更改为now()。一旦我写完这些表就会再次检查确保你的表名和数据库里的行和你代码里的匹配。如果它们不匹配，那么只需更改数据库上的名称，我已将以下名称添加到您的数据库名称中:
users(表名)、username(用户表中行名)、email(用户表中行名)、password(用户表中行名)、gender(用户表中行名)、country(用户表中行名)、ip(用户表中行名)、signup(用户表中行名)、lastlogin(用户表中行名)、notescheck(用户表中行名)。你会在表格中发现更多没有列出的行，但不用担心，因为它们会在后面的视频中添加。
我知道这个问题是在一年左右前问的，但我发帖是为了让你有答案，如果你仍然想要它，最重要的是，任何人都有同样的问题，然后你在我写这个答案后也可以找到他们需要的修复。如果这不能解决你的问题，然后张贴回复，让我知道，我会看看我是否能帮助你。
