$ b每个游戏登录尝试$ b





会话尝试仅保留值2，尽管用户仍然有超过2次尝试



我的代码是

hi2all

what i''m try to do is when user fall to login i set session to store his tries and increament it

for each faild login attempt

the session try hold only value 2 although the user still have more than 2 attempts

my code is

<?php
session_start();

  $ip = $_SERVER['REMOTE_ADDR'];
  $_SESSION['try']=1;


    @ $des=$_POST['user_pass'];

     function encrypt_pkcs7($str, $key)
{
    // derive 192-bit key using SHA-256
    $key = substr(hash('sha256', $key, true), 0, 24);
    $block = mcrypt_get_block_size(MCRYPT_3DES, MCRYPT_MODE_ECB);
    $pad = $block - (strlen($str) % $block);
    $str .= str_repeat(chr($pad), $pad);

    $ciphertext = mcrypt_encrypt(MCRYPT_3DES, $key, $str, MCRYPT_MODE_ECB);
    return base64_encode($ciphertext);
}

$password = encrypt_pkcs7('test', $des);

    $user = $_POST['name'];

    $connect = mysql_connect("localhost","root","");
    mysql_select_db("register_form",$connect);

    $query = "select id from users where name='$user' and password='$password'";

    $res = mysql_query($query,$connect);

    @$fetch = mysql_fetch_array($res);

   if($fetch['id']){

        require("html/index.html");
    }
    else{
        if(isset($_SESSION['try']))
        {
       $_SESSION['try']=$_SESSION['try']+1;

        $try=$_SESSION['try'];
        }
        else
        {
          $_SESSION['try']=1;
          $try=$_SESSION['try'];
        }
        echo($_SESSION['try']);
         require("html/re-signin.html");
         $query1="insert into login_attempts (ip,attempts) values ('$ip','$try')";

         $res1 = mysql_query($query1,$connect);






    }





?>

推荐答案

ip =

ip =

_SERVER [' REMOTE_ADDR'];

_SERVER['REMOTE_ADDR'];

_SESSION [' try'] = 1;


@

_SESSION['try']=1; @
