دوستان
من هنگامی که کدهای زیر رو اجرا میکنم میگه مشکل سشن داره
میشه بگید مشکل از کجاست ؟
خیلی برام مهمه
loginform.php
<?php
if (isset($_POST['username']) && isset($_POST['password'])){
$username = $_POST['username'];
$password = $_POST['password'];
$password_hash = md5($password);
if(!empty($username) && !empty($password)){
$query = "SELECT `id` FROM `user` WHERE `username`='$username' AND `password`='$password_hash'";
if ($query_run = mysql_query($query)){
$query_num_rows = mysql_num_rows($query_run);
if ($query_num_rows == 0){
echo 'Invalid Username/Password';
}elseif ($query_num_rows==1){
$user_id = mysql_result($query_run , 0 , 'id');
$_SESSION['user_id'] = $user_id;
header ('Location : index.php');
}
}
} else {
echo 'Please type a Username/Password';
}
}
?>
<form action="<?php echo $current_file ; ?>" method="POST">
Username : <input type="text" name="username"> Password : <input type="password" name="password">
<input type="submit" Value="Login !">
</form>
core.php
<?php
ob_start();
session_start();
$current_file = $_SERVER['SCRIPT_NAME'];
?>
config.php
<?php
$mysql_host = 'localhost';
$mysql_user = 'root';
$mysql_password = '';
$mysql_db = 'db_user';
if ( !@mysql_connect($mysql_host , $mysql_user , $mysql_password) || !@mysql_select_db($mysql_db)) {
die ( mysql_error());
}
?>
index.php
<?php
require 'config.php';
require 'core.php';
echo 'For this example type : username=admin , reza and password=123<br><br>';
if (isset($_SESSION['user_id']) && !empty($_SESSION['user_id'])){
echo 'OK';
}else{
echo 'no OK';
}
require 'loginform.php';
?>
و این هم کد خطا :
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp\htdocs\index.php:1) in C:\xampp\htdocs\core.php on line 3
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\xampp\htdocs\index.php:1) in C:\xampp\htdocs\core.php on line 3
For this example type : username=admin , reza and password=123
no OKUsername : Password :
