我有一个古玩问题，我无法解决。

在我定义的插件主文件上：

add_filter(\'pre_set_site_transient_update_plugins\', array(\'moreads_update\',\'check_4_updates\'));
add_filter(\'plugins_api\', array(\'moreads_update\',\'plugin_api_info\'),10,3);

该类功能：

static public function check_4_updates($checkdata) {
    global $wp_version;

    //var_dump($checkdata);return $checkdata;

    $options = get_option(MABASENAME);
    $options = is_serialized($options) ? unserialize($options) : $options;
    if (empty($checkdata->checked)) {return $checkdata;}
    $args = array(
        \'slug\' => MASLUG,
        \'version\' => @$checkdata->checked[MASLUG]
    );
    $request_post = array(
        \'body\' => array(
            \'action\' => \'plugin_update_check\',
            \'token\' => !empty($options[\'token\']) ? trim($options[\'token\']) : \'\',
            \'domain\' => !empty($options[\'domain\']) ? trim($options[\'domain\']) : \'\',
            \'request\' => serialize($args)
        ),
        \'user-agent\' => \'WordPress/\'.$wp_version.\'; \'.get_bloginfo(\'url\')
    );
    $raw_response = wp_remote_post(\'http://api.domain.tld/\',$request_post);
    $response = false;
    if (!is_wp_error($raw_response) && ($raw_response[\'response\'][\'code\'] == 200)) {
        $response = is_serialized($raw_response[\'body\']) ? unserialize($raw_response[\'body\']) : $raw_response[\'body\'];
    }
    if (!empty($response)) {
        if(strpos(@$response->package, self::$_apiurl) !== false) { // Only API Domain for Update Server allowed
            @$checkdata->response[MASLUG] = $response;
        }
    }
    return $checkdata;
}
static public function plugin_api_info($def, $action, $args) {
    global $wp_version;

    if (!isset($args->slug) || ($args->slug != MASLUG)) {
        return false;
    }

    $options = get_option(MABASENAME);
    $options = is_serialized($options) ? unserialize($options) : $options;
    $plugin_info = get_site_transient(\'update_plugins\');
    $current_version = @$plugin_info->checked[MASLUG];
    $args->version = $current_version;

    $request_post = array(
        \'body\' => array(
            \'action\' => $action,
            \'token\' => !empty($options[\'token\']) ? trim($options[\'token\']) : \'\',
            \'domain\' => !empty($options[\'domain\']) ? trim($options[\'domain\']) : \'\',
            \'request\' => serialize($args)
        ),
        \'user-agent\' => \'WordPress/\'.$wp_version.\'; \'.get_bloginfo(\'url\')
    );
    $response = wp_remote_post(\'http://api.domain.tld/\',$request_post);
    if (is_wp_error($response)) {
        $res = new WP_Error(\'plugins_api_failed\', __(\'An unknown error occured while connecting the plugin-API.\').\'</p><p><a href="?" onclick="document.location.reload();return false;">\'.__(\'Try again?\').\'</a>\', $response->get_error_message());
    } else {
        $res = unserialize($response[\'body\']);
        if ($res === false) {
            $res = new WP_Error(\'plugins_api_failed\', __(\'Unknown error.\'), $response[\'body\']);
        }
    }
    return $res;
}

API返回了以下对象：

Update:
$erg->slug,
$erg->package,
$erg->new_version,

Plugin-Info:
$erg->slug=array(
    \'homepage\',
    \'name\',
    \'version\',
    \'author\',
    \'last_updated\',
    \'external\',
    \'requires\',
    \'tested\',
    \'downloaded\',
    \'package\',
    \'download_link\',
    \'sections\' => array(
        \'description\',
        \'change_log\',
        \'other_notes\'
    )
);

在一个博客上，一切都很好。如果我设置了新版本，更新将显示在Wordpress更新页面上。

但在一个多站点的博客上，我什么都看不到。我只在多站点、网络范围内的一个博客上尝试过，还激活了第一个博客，没有可用的更新。

如果我能和

set_site_transient(\'update_plugins\', null);
add_filter(\'plugins_api_result\',function($res,$action,$args){print_r(array($res,$action,$args));return $res;});

我的更新例程“check\\u 4\\u updates（）”不会在多站点上调用！

这里发生了什么事，怎么了？

谢谢Stefan
