该类来自其他人的WP插件，我想改编该类中的一个函数（还有更多函数）。

（编辑后的）原始代码：

class some_class {
    private function get_section_url() {
        $full_url = add_query_arg( \'action\', \'action-name\', admin_url( \'users.php\' ) );
        $relative_url = str_replace( get_site_url(), \'\', $full_url );
        return $relative_url;
    }
}

我想用以下内容覆盖上述函数：

function get_section_url() {
    $full_url = add_query_arg( \'action\', \'action-name\', admin_url( \'users.php\' ) );
    return $full_url;
}

如何做到这一点？我尝试了一些建议的解决方案(here 和here), 但没有成功。

UPDATE

以这种方式调用原始函数（仅来自同一类）：

public function parent_file($parent_file) {
    global $current_screen, $submenu_file, $typenow;
    if ( $current_screen->base == \'users\' && request_param( \'action\' ) == \'action-name\' ) {
        $parent_file = \'parent.php\';
        $submenu_file = $this->get_section_url();
        $typenow = \'hide-users-menu\';
    }
    return $parent_file;
}

public function menu() {
    global $submenu;
    $capability = admin_capability();
    if ( current_user_can( $capability ) ) {
        $url = $this->get_section_url();
    $submenu[\'parent.php\'][] = array( __( \'Menu Item Title\' ), $capability, $url );
    }
}

add_action("admin_menu", function () {

    $parent_file = \'parent.php\';
    $full_url = add_query_arg( \'action\', \'action-name\', admin_url( \'users.php\' ) );


    global $submenu;


    // searching the last submenu
    $last = array_pop($submenu[$parent_file]);

    // correcting the URL
    $last[2] = $full_url;

    // replacing in the array
    $submenu[$parent_file][] = $last;

}, 20);
// default priority (used by the plugin) is 10, so I choose 20 to be sur that it comes after the plugin
