可以使用for循环创建多个自定义Post类型吗？

我正在尝试使用for循环在插件中创建多个自定义帖子类型。插件选项页面允许用户设置自定义帖子类型的数量以及自定义帖子类型的单数和复数名称。

当我运行下面的代码时，wordpress只注册最后一个自定义帖子类型。下面是我使用的代码：

<?php 
if($options_foo[\'num_post_types\'] > 0 ) {
for($i =1; $i <= $options_foo[\'num_post_types\']; $i++) {
    global $options_foo;
    $singular = $options_foo[\'post_type_names\'][$i][\'singular\'];
    $plural = $options_foo[\'post_type_names\'][$i][\'plural\'];
    add_action(\'init\', function(){
        global $singular;
        global $plural;
        $labels = array(
            \'name\'                  => $plural,
            \'singular_name\'         => $singular,
            \'add_new\'               => "New $singular",
            \'add_new_item\'          => "New $singular",
            \'edit_item\'             => "Edit $singular",
            \'new_item\'              => "New $singular",
            \'view_item\'             => "View $singular",
            \'view_items\'            => "View $plural",
            \'search_items\'          => "Search $plural",
            "not_found"             => "No $plural Found",
            "not_found_in_trash"    => "No $plural Found in Trash",
            \'all_items\'             => "All $plural",
            \'attributes\'            => "$singular Attributes",
            \'insert_into_item\'      => "Insert to $singular",
            \'uploaded_to_this_item\' => "Uploaded to this $singular"
        );
        $supports = array(\'title\', \'thumbnail\');
        $args = array(
            \'labels\'                => $labels,
            \'public\'                => true,
            \'exclude_from_search\'   => true,
            \'publicly_queryable\'    => true,
            \'show_in_nav_menus\'     => false,
            \'show_in_admin_bar\'     => false,
            \'menu_position\'         => 5,
            \'menu_icon\'             => \'dashicons-admin-home\',
            \'supports\'              => $supports,
            \'can_export\'            => \'true\'
        );
        register_post_type($singular, $args);
    });
}//end for
}//end if

for($i =1; $i <= $options_foo[\'num_post_types\']; $i++) { global $options_foo; $singular = $options_foo[\'post_type_names\'][$i][\'singular\']; $plural = $options_foo[\'post_type_names\'][$i][\'plural\']; add_action(\'init\', function(){ global $singular;

add_action( \'init\', function () { global $options_foo; if ( $options_foo[\'num_post_types\'] > 0 ) { for ( $i=1; $i <= $options_foo[\'num_post_types\']; $i++) { $singular = $options_foo[\'post_type_names\'][$i][\'singular\']; $plural = $options_foo[\'post_type_names\'][$i][\'plural\']; $labels = array( \'name\' => $plural, \'singular_name\' => $singular, \'add_new\' => "New $singular", \'add_new_item\' => "New $singular", \'edit_item\' => "Edit $singular", \'new_item\' => "New $singular", \'view_item\' => "View $singular", \'view_items\' => "View $plural", \'search_items\' => "Search $plural", "not_found" => "No $plural Found", "not_found_in_trash" => "No $plural Found in Trash", \'all_items\' => "All $plural", \'attributes\' => "$singular Attributes", \'insert_into_item\' => "Insert to $singular", \'uploaded_to_this_item\' => "Uploaded to this $singular" ); $supports = array(\'title\', \'thumbnail\'); $args = array( \'labels\' => $labels, \'public\' => true, \'exclude_from_search\' => true, \'publicly_queryable\' => true, \'show_in_nav_menus\' => false, \'show_in_admin_bar\' => false, \'menu_position\' => 5, \'menu_icon\' => \'dashicons-admin-home\', \'supports\' => $supports, \'can_export\' => \'true\' ); register_post_type($singular, $args); } } });
