Post data in emails

I'm trying to get a forget password script working.

when a user forgets their password and inputs their username only, it sends them email that includes a form which has a new password input. my main question is how do i carry post data from that email in outlook or whatever email client they are using into the browser. so far it hasnt been able to work.

this is the php code.

<?php

include("includes/sql_system.php"); // System Functions
if ($_SERVER['QUERY_STRING'] == "submit_login")
{
$user_id = evaluateVariable('user_id');
$mysql = mysql_query ("SELECT * FROM $members_table WHERE $usernameField='$user_id'") or die (mysql_error());
$rowcount = mysql_num_rows ($mysql);
if ($rowcount == "0")
{
beginLayout();
showError("UserError, your User Name is Wrong, please go back and try again.");
endLayout();
exit;
}
if ($rowcount != "0")
{
beginLayout();
$new_pass = randomPass();
$email_address = "";
$new_link = "http://" . $_SERVER['SERVER_NAME'] . $folder . "system_forget.php?activate";
while ($sql = mysql_fetch_array($mysql))
{
$email_address .= $sql[$emailField];
}
echo "An email has been sent to <u>" . $email_address . "</u> with your new password. If this email is not correct please contact an admin.";
endLayout();
$email_subject = "Monitor CMS - Lost Password";
$html_string = "<html>\n<body>";
$html_string .= "<div style=\"font-family: tahoma; font-size: 10px; color: #555555;\">";
$html_string .= "<form action=\"" . $new_link . "\" method=\"post\">\n";
$html_string .= "<input type=\"hidden\" name=\"user_id\" value=\"" . $user_id . "\" />\n";
$email_message = "<b>MONITOR CMS " . date("m/d/Y") . "</b>\n\n";
$email_message = "Enter a new password and submit the form, the new password must be between 6 - 10 characters.\n\n";
$email_message .= "<b>User Name</b>: " . $user_id . "\n";
$email_message .= "<b>New Password</b>: <input style=\"font-family: tahoma; font-size: 10px;\" type=\"password\" maxlength=\"10\" name=\"pass\" />\n";
$email_message .= "<input style=\"font-family: tahoma; font-size: 10px;\" type=\"submit\" />";
$email_message .= "\n\n\n<u>Message Sent From " . $systemTitle . "</u>\n";
$html_string_end = "</form></div></body></html>\n";
$headers = "From: Monitor CMS\n";
$headers .= "X-Sender: <mail@server.com>\n";
$headers .= "X-Mailer: PHP\n"; //mailer
$headers .= "X-Priority: 3\n"; //1 UrgentMessage, 3 Normal
$headers .= "Return-Path: <mail@server.com>\n";
$headers .= "Content-Type: text/html; charset=iso-8859-1\n";
mail($email_address, $email_subject, $html_string . nl2br($email_message) . $html_string_end , $headers) or die ("unable to send email");
}
}
elseif ($_SERVER['QUERY_STRING'] == "activate")
{
if (evaluateVariable('pass'))
{
if (strlen(evaluateVariable('password')) < 6)
{
beginLayout();
showError("Your new password must be atleast 6 characters, please refer to the email again.");
endLayout();
}
else
{
// Mysql Procedures
}
}
else
{
beginLayout();
showError("You haven't submited a new password, please refer to the email again.");
endLayout();
}
}
else
{
if ($_COOKIE['user_id'] != "")
{
header ("Location: $frontpage");
}
else
{
beginLayout();
?>
<form name="mcms_forget" action="system_forget.php?submit_login" method="post">
<table cellspacing="0" cellpadding="5" style="border: 1px solid #c9c9c9;" bgcolor="#f9f9f9">
<tr>
<td >User Name</td>
<td><input type="text" name="user_id" size="30" maxlength="25" /></td>
</tr>
<tr>
<td></td>
<td><input type="button" style="background-color: #F9F9F9; border: 0px; text-decoration: underline;" onmouseover="this.style.color='#ED135A';this.style.textDecorati on='none'" onmouseout="this.style.color='#000000';this.style.textDecorati on='underline'" value="Submit" onclick="mcms_forget_validate(this.form);" /></td>
</tr>
</table>
<a href="system_login.php">Back to Login</a>
</form>
<?php
endLayout();
}
}
?>

This is the email html source

<html>
<body><div style="font-family: tahoma; font-size: 10px; color: #555555;"><form action="" method="post">
<input type="hidden" name="user_id" value="Combust" />
Enter a new password and submit the form, the new password must be between 6 - 10 characters.<br />
<br />
<b>User Name</b>: Combust<br />
<b>New Password</b>: <input style="font-family: tahoma; font-size: 10px;" type="password" maxlength="10" name="pass" /><br />
<input style="font-family: tahoma; font-size: 10px;" type="submit" /><br />
<br />
<br />
<u>Message Sent From </u><br />
</form></div></body></html>

i took out the action/domain for this post for security reasons. they are there properly in the actual script so that ins't the problem.

and the evaluateVariable() function just checks if $_POST or $_REQUEST/$_GET has been set otherwise it returns false.

Thank you.
