PLEASE HELP! Error check not working

ShadowIce · August 16, 2010

Hi all. Ok, I've been trying to fix this for 5 days straight. for some reason, i can't get this code to check the value for email, question and answer against the database. it either gives an error all the time or it allows incorrect data..

forgot.php:

<?php 
if ($_SERVER["REQUEST_METHOD"] == "POST") { print_r($_POST); }
if ($_SERVER["REQUEST_METHOD"] == "GET") { print_r($_GET); }
error_reporting(E_ALL);
include 'dbc.php';




/******************* ACTIVATION BY FORM**************************/

if(isset($_POST['doReset'])){
if ($_POST['doReset']=='Reset')
{
$err = array();
$msg = array();

foreach($_POST as $key => $value) {
$data[$key] = filter($value);
}

//check if activ code and user is valid as precaution
if(isset($data['user_email'])){
$rs_check = mysql_query("select id from users where user_email='$data[user_email]'") or die (mysql_error()); 
$num = mysql_num_rows($rs_check);

}

  // Match row found with more than 1 results  - the user is authenticated. 
/*    if ( $num <= 0 ) { 
$err[] = "Error - Sorry no such account exists or registered.";
//header("Location: forgot.php?msg=$msg");
//exit();
}*/

if(isset($_POST['user_email'])){
if($_POST['user_email1'] != stripslashes(isEmail($data['user_email']))) {
$err[] = "ERROR - Please enter a valid email"; 
}
}
if(isset($_POST['usr_question'])){
if($_POST['usr_question1'] != stripslashes($data['usr_question'])) {
$err[] = "ERROR - Please enter a valid question"; 
}
}
if(isset($_POST['usr_answer'])){
if($_POST['usr_answer1'] != stripslashes($data['usr_answer'])) {
$err[] = "ERROR - Please enter a valid answer"; 		 
}
}

if(empty($err)) {

$new_pwd = GenPwd();
$pwd_reset = PwdHash($new_pwd);
//$sha1_new = sha1($new);	
//set update sha1 of new password + salt
if(isset($data['user_email']) && isset($data['usr_question']) && isset($data['usr_answer'])){
$rs_activ = mysql_query("update users set pwd='$pwd_reset' WHERE 
					 user_email='$data[user_email]' AND usr_question='$data[usr_question]' AND usr_answer='$data[usr_answer]'") or die(mysql_error());					 
$host  = $_SERVER['HTTP_HOST'];
$host_upper = strtoupper($host);

echo "Here is your new password:<br>\r\n"
.$new_pwd."<br>\r\n";

}

anyone?..

Since you didn't state what it IS doing (what error, what wrong data) no one knows where to even start looking at in all the code.

ShadowIce · August 16, 2010

the error is that it always either lets you submit your secret user question, secret user question, and email as opposed to checking the database to make SURE it is right.
