首先检查用户是否已经登录,如果已经登录就返回info目录下的页面。
<?phpglobal $current_user;$loginuserid = $current_user->ID;if($loginuserid){//如果已经登录header("Location:".get_bloginfo('url')."/info/"); exit;}
如果用户未登录;验证登录。
<?if($_POST){$username = $_POST['username'];$password = $_POST['password'];//判断是否存在,存在则返回用户id$user_id = username_exists($username);if ($user_id){//验证登录名是否正确if(!user_pass_ok($username, $password)){echo "<script language='javascript'>alert('帐号或者密码错误!');</script>";echo "<script language='javascript'>location='". get_bloginfo('url')."/login/';</script>";exit;}else{wp_set_auth_cookie($user_id,false,$secure);echo "<script language='javascript'>location='". get_bloginfo('url')."/info/';</script>";exit;}}else{echo "<script language='javascript'>alert('帐号或者密码错误!');</script>";echo "<script language='javascript'>location='". get_bloginfo('url')."/login/';</script>";exit;}} ?>
