我能在上解决这个问题https://wordpress.stackexchange.com/users/4771/milo 建议为此，我在theme customizer中创建了一个下拉菜单，从中可以选择一个虚拟静态页面作为公文包页面。我在下拉菜单中使用了以下代码：

add_action( \'customize_register\', \'th_customize_register\' );

function th_customize_register($wp_customize) { 

    // Add: Drop Down Pages
    $wp_customize->add_setting( \'th_portfolio_page_id\', array (
        \'sanitize_callback\' => \'absint\',
    ) );

    $wp_customize->add_control(\'th_portfolio_page_id\', array(
        \'label\'    => esc_html__(\'Portfolio Page\', \'themeshash\'),
        \'description\' => esc_html__( \'You must have to define it if you want to set your portfolio as your homepage.\', \'themeshash\' ),
        \'section\'  => \'title_tagline\',
        \'type\'     => \'dropdown-pages\',
    ) );


}

设置完此下拉列表后，现在我们可以添加以下代码，有条件地将上述定义的静态页面分配给archive-{post-type}.php

if ( get_option(\'page_on_front\') == get_theme_mod(\'th_portfolio_page_id\')  ) {

    add_action("pre_get_posts", "th_assign_portfolio_page");

    function th_assign_portfolio_page($wp_query){
        //Ensure this filter isn\'t applied to the admin area
        if(is_admin()) {
            return;
        }

        if($wp_query->get(\'page_id\') == get_option(\'page_on_front\')):

            $wp_query->set(\'post_type\', \'post-type-name-here\');
            $wp_query->set(\'page_id\', \'\'); //Empty

            //Set properties that describe the page to reflect that
            //we aren\'t really displaying a static page
            $wp_query->is_page = 0;
            $wp_query->is_singular = 0;
            $wp_query->is_post_type_archive = 1;
            $wp_query->is_archive = 1;

        endif;

    }

}

使用此方法，现在可以选择任何虚拟静态页面作为我们的post类型归档页面，只需一次，然后我们可以像其他页面一样将该静态页面设置/取消设置为首页。
