将插件页分离为不同文件的问题

Question

由于我的最后一个(第一个)插件变得有点难以管理与6个管理页在一个文件，我决定将他们分开为这一个，但我得到的只是问题这样做。

在我的插件函数文件(LoadPressFunctions.php)中，我有以下内容：

add_action( 'admin_menu', 'my_plugin_menu' );

function my_plugin_menu() {
    add_menu_page( 'LoadPress', 'LoadPress', 'manage_options', 'LoadPressPlugin', 'LoadPress_Plugin', 'dashicons-download', 99  );
}

function LoadPress_Plugin() {
    if ( !current_user_can( 'manage_options' ) )  {
        wp_die( __( 'You do not have sufficient permissions to access this page.' ) );
    }
    include 'LoadPressOptions-Home.php';
}

在我的LoadPressOptions- have . And文件中，我有以下内容：

<?php
echo '<style>
    h1 {
        letter-spacing: 8px;
    }
    .sectionHeader {
        background-color: #E5E5E5;
        padding: 1px 10px 1px 10px;
        margin: 10px 0px 0px 0px;
        border-left: 4px solid #2A333E;
    }
    .sectionNotification {
        background-color: #E5E5E5;
        padding: 1px 10px 1px 10px;
        margin: 5px 0px 0px 0px;
        border-left: 4px solid #ffce1f;
    }
    ul#adminmenu a.wp-has-current-submenu:after, ul#adminmenu>li.current>a.current:after {
        border-right-color: #12171C;
    }
  </style>';

    echo '<div class="wrap">';
    echo '<h1>LoadPress</h1>';
    echo '<p class="description" id="tagline-description">Simplify Brilliance, Simplify Life.</p>';
    ?>
    <h2 class="nav-tab-wrapper">
            <a class="nav-tab nav-tab-active" href="<?php echo admin_url() ?>admin.php?page=LoadPressPlugin">Home</a>
            <!--<a class="nav-tab" href="<?php echo admin_url() ?>admin.php?page=LoadPressPlugin-Settings">Settings</a>-->
            <a class="nav-tab" href="<?php echo admin_url() ?>admin.php?page=LoadPressPlugin-About">About/Credits</a>
            <a class="nav-tab" style="background-color: red;">Settings (Not available in Alpha)</a>
            <a class="nav-tab" href="<?php echo admin_url() ?>admin.php?page=LoadPressPlugin-Docs">Documentation</a>
            <a class="nav-tab" style="background-color: red;">Email Editor (Coming Soon)</a>
        </h2>
        <?php
//Options
    echo '<div>';
    ?>
    <img src="<?php echo get_site_url() ?>/wp-content/plugins/LoadPress/LoadPressLogo-Banner.png" style="margin-top: 10px;"/>
<?php
    echo '</div>';
?>
    <div class="sectionNotification">
    <h3>Thank You for choosing LoadPress</h3>
    </div>

    <div class="sectionHeader">
    <h3>What is LoadPress?</h3>
    <p>LoadPress is a professional plugin that allows site community members to post downloadable files, such as modifications, save files and other community applicable files.</p>
    <p>This plugin was developed for use primarily with modding communities for video games, and other video game related products, and uses a simplistic yet robust setup with several different fallbacks in case of mistakes.</p>
    <p>At the time of writing this, LoadPress is primarily used for in-house projects developed by Kyle Briggs & Don Briggs Ltd.</p>
    </div>

    <div class="sectionHeader">
    <h3>Why LoadPress?</h3>
    <p>LoadPress is an excellent choice for targeted community functionality as it offers several things other plugins do not:</p>
    <ol>
        <li>It allows users to upload files in any format (settable by editing the plugin).</li>
        <li>It allows total administrative control over all files, but only gives regular users access to their own.</li>
        <li>It simplifies the Media section to only display a regular user's own media (admins can see all).</li>
        <li>It is the ONLY plugin currently available for Wordpress that offers this functionality tailored specifically to file-sharing, and works seamlessly with any SEO package.</li>
        <li>At the core, it runs on Wordpress' own API so the custom post type can be edited to your needs easily.</li>
    </ol>
    </div>

    </div>
    <?php

但是现在我得到了一个空白页，因为我已经将这个内容从主文件移到了它自己的文件中，没有从它加载任何内容。

如果我将文件内容替换为：

<?php
echo '<h1>Hi</h1>';

一切正常，但我看不到Home.php内容的语法错误，因为它是直接从函数中复制和粘贴的(并添加了)。

有什么想法吗？

在wordpress中启用调试了吗？

在根wordpress文件夹中打开wp-config.php并更改以下行：

define('WP_DEBUG', false);

至

define('WP_DEBUG', true);

然后，PHP错误将输出到屏幕上。
