我对Wordpress的所有东西都很陌生，似乎真的被我读到的东西弄糊涂了。

我正在做的是为一个特定的工作创建一个插件，登录后我只需更改菜单。现在我使用DIVI 2作为一个主题，我在函数中有这个主题。插件的php：

function my_wp_nav_menu_args( $args = \'\' ) {

if( is_user_logged_in() ) {
    $args[\'menu\'] = \'UserMenu\';
} else {
    $args[\'menu\'] = \'MainMenu\';
}
return $args;
}
add_filter( \'wp_nav_menu_args\', \'my_wp_nav_menu_args\' );

这似乎有道理，但不起作用，我不确定这是Divi2，还是经过多次测试，用户没有登录。它一直是假的is_user_logged_in().

以下是我用于自定义登录的代码：

<?php
/**
 * Created by PhpStorm.
 * User: Andrew
 * Date: 08/11/2017
 * Time: 11:21
 */
global $wpdb;
$userOK = -1;
print_r(is_user_logged_in());
if(is_user_logged_in()) { //This does not action, ever!
    ?>
    <script>
     window.location.href = "https://URL.uk/userhome/";
    </script>
    <?php
}

if($_POST[\'wd_resendActivationButton\'] === \'resend\') {
    sendActivation($_POST[\'userid\'], $_POST[\'useremail\'],"2");
}

if($_POST[\'loginEmail\'] && $_POST[\'loginPassword\'] && !$_POST[\'wd_resendActivationButton\']){
    $userOK = 0;
    $user = wp_authenticate( $_POST[\'loginEmail\'] , $_POST[\'loginPassword\'] );
    if(is_wp_error($user)) {
        echo $user->get_error_message();
    } else {
        if($user->user_status === "0") {
            wp_logout();
        } else {
            ?>
            <script>
                window.location.href = "https://url.uk/userhome/";
            </script>
            <?php
        }
    }
}

据我所知，wp_authenticate 用户也登录了，但似乎没有这样做。所以不知道问题出在哪里。有人能给我指一下正确的方向吗？

UPDATE

使用以下代码，很明显wp\\U身份验证失败，尽管它确实给了我用户对象，但它不会让用户登录：

    if($_POST[\'loginEmail\'] && $_POST[\'loginPassword\'] && !$_POST[\'wd_resendActivationButton\']){
    $userOK = 0;
    $user = wp_authenticate( $_POST[\'loginEmail\'] , $_POST[\'loginPassword\'] );
    if(is_wp_error($user)) {
        echo $user->get_error_message();
    } else {
        if($user->user_status === "0") {
            wp_logout();
        } else {
            if(is_user_logged_in()) {
                ?>
                <script>
                    console.log(\'logged in\');
                    window.location.href = "https://URL.uk/userhome/";
                </script>
                <?php
            } else {
                ?>
                <script>
                    console.log(\'Not logged in\');
                    window.location.href = "https://URL.uk/";
                </script>
                <?php
            }
        }
    }
}

谢谢
