java - 已发送带有确认链接的 PHP 电子邮件，但确认链接不起作用

Question

我正在生成一封电子邮件并在一个文件中发送，该电子邮件中的一个链接链接到我的确认页面，然后该页面应根据用户所做的选择在数据库表中移动用户名。问题是我从确认页上什么也没有得到，即使我只使用一个简单的打印语句而没有其他任何东西。我一直在试图找出答案，但无济于事，错误报告也返回空白。这里有两个文件:

email.php(完全有效)

<?php 

$link= mysql_connect(...............); //Establish connection to the MySQL server

if (!$link) {
die('Could not connect: ' . mysql_error());
}

mysql_select_db(.....);

$confirm = md5(uniqid(rand()));
$position = $_POST['position'];
$team_name = $_POST['team_name'];
$zip_code = $_POST['zip_code'];
$userId = $_POST['userId'];

$s=mysql_query("SELECT Coach, TeamId FROM TEAM WHERE TEAM.Name = '$team_name' AND TEAM.Zip     ='$zip_code'") OR die ("Error 1"); //Get result from query

while($row=mysql_fetch_assoc($s))
{ 
$coachId = $row['Coach'];
$teamId = $row['TeamId'];   
}

$l=mysql_query("SELECT Name, Email FROM USER WHERE USER.UserId = '$userId'") OR die ("Error 3");     //Get result from query

while($row = mysql_fetch_assoc($l))
{
$user_name = $row['Name'];
$user_email = $row['Email'];
}

$q=mysql_query("SELECT Name, Email FROM USER WHERE USER.UserId = '$coachId'") OR die ("Error 4"); //Get result from query

while($coach=mysql_fetch_assoc($q))
{
 $to = $coach['Email']; 
 $name = $user_name;
 $subject = "Scoutlet $position Request for The $team_name"; 

 if($position == "Head Coach")
 {
    $message = "$name has requested to become the Head Coach for the $team_name."; 
    $message .= "\n\nClick on the following link to give $name permission to be the Head Coach of the $team_name (Located in the ZIP code $zip_code).\n\n";
    $message .="<a href=\"http://web.***.***/~***/confirmation.php?key=$confirm\">Click Here to make $name the Head Coach</a>";
 }

     $message = "$name has requested to become a Score Keeper for the $team_name.";
     $message .= "\n\nClick on the following link to give $name permission to be a Score Keeper for the $team_name (Located in the ZIP code $zip_code).\n\n";

    }
    else

    }

我已经浪费了大量的时间来尝试错误检查，这是一种浪费，所以希望更多的眼睛能够帮助更快地解决问题。任何帮助或建议都会很棒。提前致谢
