未设置会话

Question

我有以下代码，但由于某种原因，会话保持为空。

有人能帮我解决这个问题吗？

<?php

session_start();

ob_start();

$ifLogged = $_SESSION["mbse"];

if(!isset($ifLogged))
{
    $_SESSION["mbse"] = 'not logged';
}

echo '--'.$ifLogged.'--';

//Obtain Info if User Tried to Log In
$username = $_POST[username];
$password = $_POST[password];
$submit = $_POST[submit];

if(isset($submit))
{

    $_SESSION["mbse"] = $username;

    $user = get_user_by( 'login', $username );
    if ( $user && wp_check_password( $password, $user->data->user_pass, $user->ID) )
    {

        // Automatic login //
        $user = get_user_by('login', $username );

        // Redirect URL //
        if ( !is_wp_error( $user ) )
        {
            wp_clear_auth_cookie();
            wp_set_current_user ( $user->ID );
            wp_set_auth_cookie  ( $user->ID );

            echo '<meta http-equiv="refresh" content="0;URL=/landing-page" />';


            exit();
        }
        else
        { echo 'Error';}
        //Stop Here
    }
    else
    {
       echo "Username and Passcode Do Not Match";
    }
}

//Obtain Domain and Check Alias
$domain = "$_SERVER[HTTP_HOST]";
$alias = "$_SERVER[REQUEST_URI]";

//Strip the Slashes from the Alias

$alias = str_replace("/", "", $alias);

if($alias == '')
{
    $nameInput = 'text';
}
else
{
    $nameInput = 'hidden';
}


echo'

<form method="POST">
 <div class="form-group">
<input class="form-control" type="'.$nameInput.'" value="'.$alias.'" name="username" placeholder="Input Your Username" required>
</div>
<div class="form-group">
<input class="form-control" type="password" name="password" placeholder="Input Your Password"  required />
</div>
<div class="col-sm-12  submitlogin">
<input class="btn" type="submit" name="submit" value="Submit" />
</div>
</form>';

无论是从下一个页面，还是当我返回到这个页面时-会话最初是空的，在第一次尝试之后，它显示为“未记录”。问题是，当重定向发生时，条件会被触发。

非常感谢您的帮助！

发现了，这比它应该花的时间更长，抱歉

数组键需要用引号括起来，如下所示

$username = $_POST['username'];
$password = $_POST['password'];
$submit = $_POST['submit'];
