我正在使用此代码为我的插件创建菜单。这很有效。
我的问题是：在foo\\u admin\\u enqueue\\u scripts回调中包含一些php页面和将一些脚本/样式排队与在add\\u menu\\u page/add\\u submenu\\u page回调中包含它们有什么区别？
function foo_admin_menu(){
$menu = add_menu_page(\'Player manager\', \'Foo Audio Player\', FOO_CAPABILITY, \'foo_settings\', \'foo_settings_page\', \'dashicons-playlist-audio\');
$submenu = add_submenu_page(\'foo_settings\', __(\'Foo Audio Player\', FOO_TEXTDOMAIN), __(\'Settings\', FOO_TEXTDOMAIN), FOO_CAPABILITY, \'foo_settings\', \'foo_settings_page\');
$submenu2 = add_submenu_page(\'foo_settings\', __(\'Foo Audio Player\', FOO_TEXTDOMAIN), __(\'Player manager\', FOO_TEXTDOMAIN), FOO_CAPABILITY, \'foo_player_manager\', \'foo_player_manager_page\');
add_action( \'load-\' . $menu, \'foo_admin_enqueue_scripts\' );
add_action( \'load-\' . $submenu, \'foo_admin_enqueue_scripts\' );
add_action( \'load-\' . $submenu2, \'foo_admin_enqueue_scripts\' );
}
function foo_settings_page(){
//1. include php page and script here?
include("settings.php");
wp_enqueue_script(\'enqueue something here\')
}
function foo_player_manager_page(){
...
}
function foo_admin_enqueue_scripts() {
//2. or include php page and script here?
wp_enqueue_script(\'jquery\');
wp_enqueue_media();
wp_enqueue_style(\'foo\', plugins_url(\'/css/admin.css\', __FILE__));
wp_enqueue_script(\'foo\', plugins_url(\'/js/admin.js\', __FILE__), array(\'jquery\'));
}

主要区别在于(link) 或脚本标记位于源中，或资源是否加载到head 或页脚。
带有add_menu_page()/add_submenu_page() 像您的foo_settings_page(), 样式/脚本文件将加载到body （交割前body 标记），因为head 在回调(foo_settings_page()) 被称为：
<body>
...
the content of your plugin page (added through foo_settings_page())
...
...
<!-- The style/script file would be loaded here, in the footer. -->
</body>
foo_admin_enqueue_scripts() 这是一个
load-<page hook> 回调时，样式/脚本文件将加载到
head &mdash；但对于脚本，它可以在页脚中；检查第五个参数
wp_enqueue_script():
<head>
...
<!-- The style/script file would be loaded here, unless if the *script* is set
to be loaded in the footer. -->
...
</head>
head 和页脚中的脚本文件&mdash；虽然在现代，剧本
may be put in the head.
