在WordPress中创建选项菜单

我有一些代码可以在WordPress中创建"选项"菜单。我正在使用文档化的示例，但我不确定如何使其发挥作用。理想情况下，我想在主题的其他地方使用用户在管理表单中输入的值，比如：

<?php echo_the_twitter_link(); ?>

这是当前代码：

<?php
/*
Plugin Name: Admin Menu
Plugin URI: x
Description: x
Author: x
Author URI: x
*/
// create custom plugin settings menu
add_action('admin_menu', 'baw_create_menu');
function baw_create_menu() {
    //create new top-level menu
    add_menu_page('BAW Plugin Settings', 'BAW Settings', 'administrator', __FILE__, 'baw_settings_page');
    //call register settings function
    add_action( 'admin_init', 'register_mysettings' );
}

function register_mysettings() {
    //register our settings
    register_setting( 'baw-settings-group', 'new_option_name' );
    register_setting( 'baw-settings-group', 'some_other_option' );
    register_setting( 'baw-settings-group', 'option_etc' );
}
function baw_settings_page() {
?>
<div class="wrap">
<h2>Social Media Links</h2>
<form method="post" action="options.php">
    <?php settings_fields( 'baw-settings-group' ); ?>
    <table class="form-table">
        <tr valign="top">
        <th scope="row">New Option Name</th>
        <td><input type="text" name="new_option_name" value="<?php echo get_option('new_option_name'); ?>" /></td>
        </tr>
        <tr valign="top">
        <th scope="row">Some Other Option</th>
        <td><input type="text" name="some_other_option" value="<?php echo get_option('some_other_option'); ?>" /></td>
        </tr>
        <tr valign="top">
        <th scope="row">Options, Etc.</th>
        <td><input type="text" name="option_etc" value="<?php echo get_option('option_etc'); ?>" /></td>
        </tr>
    </table>
    <p class="submit">
    <input type="submit" class="button-primary" value="<?php _e('Save Changes') ?>" />
    </p>
</form>
</div>
<?php } ?>
