如何在 octobercms 后端验证表单

Question

我扩展了 october cms 后端，因此它有更多元字段，我想验证这些字段，这就是我创建额外字段的方式：

（插件.php）

public function boot()
    {

      Event::listen('backend.form.extendFields', function($widget)
        {
          if (!$widget->model instanceof \Cms\Classes\Page) return;
          //cms page fields
                    $widget->addFields([
                      'settings[str_seo_title]' =>[
                        'label' => 'Meta Title',
                        'tab'     => 'SEO',
                        'type' => 'text'
                      ],
                      'settings[str_seo_description]' =>[
                        'label' => 'Meta Description',
                        'tab'     => 'SEO',
                        'size'    => 'small',
                        'type' => 'textarea'
                      ],
                      'settings[str_seo_keywords]' =>[
                        'label' => 'Meta Keywords',
                        'tab'     => 'SEO',
                        'type' => 'text'
                      ],
                      'settings[str_canonical_url]' => [
                                    'label'   => 'Canonical URL',

                                    'tab'     => 'SEO',

                                ],
                      'settings[str_robot_index]' => [
                        'label'   => 'Robot Index',

                        'default' => 'follow',
                        'span'    => 'right'

                        'tab'   => 'Facebook Tags',
                      ]
          ],  'primary');

               });
}
}

我已经阅读了文档，但我没有理解它。

我发现的方法是在插件的 boot() 方法中绑定页面验证事件，如下所示：

        \CMS\Classes\Page::extend(function($model) {
        $model->bindEvent('model.beforeValidate', function() use ($model) {
            if ($model->url == "/") {
                $model->rules['main_title'] = 'required';
            }
        });
    });
