我有这个页面显示在 wordpress 管理员的外观顶部菜单下。我创建了另一个顶部菜单部分，称为镜头（通过创建自定义帖子类型）并希望此页面位于那里。
我要编辑代码的哪一部分？我去了wordpress的codex，它通过add_submenu_page（$parent_slug，$page_title，$menu_title，$capability，$menu_slug，$function）向我展示了一种方法
但是我拥有的代码没有add_submenu_page()我可以更改的功能：
<?php
// Default options values
$sa_options = array(
'footer_copyright' => '© ' . date( 'Y' ) . ' ' . get_bloginfo( 'name' ),
'intro_text' => '',
'featured_cat' => '',
'layout_view' => 'fixed',
'author_credits' => true
);
if( is_admin() ) : // Load only if we are viewing an admin page
function sa_register_settings()
{
// Register settings and call sanitation functions
register_setting( 'sa_theme_options', 'sa_options', 'sa_validate_options' );
}
add_action( 'admin_init', 'sa_register_settings' );
// Store categories in array
$sa_categories[0] = array(
'value' => 0,
'label' => ''
);
$sa_cats = get_categories();
$i = 1;
foreach( $sa_cats as $sa_cat ) :
$sa_categories[$sa_cat->cat_ID] = array(
'value' => $sa_cat->cat_ID,
'label' => $sa_cat->cat_name
);
$i++;
endforeach;
// Store layouts views in array
$sa_layouts = array(
'fixed' => array(
'value' => 'fixed',
'label' => 'Fixed Layout'
),
'fluid' => array(
'value' => 'fluid',
'label' => 'Fluid Layout'
),
);
function sa_theme_options()
{
// Add theme options page to the addmin menu
add_theme_page( 'Theme Options', 'Theme Options', 'edit_theme_options', 'theme_options', 'sa_theme_options_page' );
}
add_action( 'admin_menu', 'sa_theme_options' );
// Function to generate options page
function sa_theme_options_page()
{
global $sa_options, $sa_categories, $sa_layouts;
if( !isset( $_REQUEST['updated'] ) )
$_REQUEST['updated'] = false; // This checks whether the form has just been submitted.
?>
<div class="wrap">
<?php screen_icon();
echo "<h2> WP Live-shot" . __( ' Theme Options' ) . "</h2>";
// This shows the page's name and an icon if one has been provided
?>
<?php if( false !== $_REQUEST['updated'] ) : ?>
<div class="updated fade"><p><strong><?php _e( 'Options saved' ); ?></strong></p></div>
<?php endif; // If the form has just been submitted, this shows the notification ?>
<form method="post" action="options.php">
<?php $settings = get_option( 'sa_options', $sa_options ); ?>
<?php settings_fields( 'sa_theme_options' );

including a nonce, a unique number used to ensure the form has been submitted from the admin page
and not somewhere else, very important for security */

使用该功能重建对我来说有点太复杂了add_submenu_page()，有人可以帮忙吗？自定义帖子类型的名称是wp_live_shot。
