控制器

$companyObj = new Company();
           
$city = City::findOne(['name' => $post["CabinetRegistrationForm"]["city_name"]]);
            
$companyObj->name = $post["CabinetRegistrationForm"]["company_name"];
$companyObj->activity = 1;
$companyObj->district_id = $city->district_id;
$companyObj->region_id = $city->region_id;
$companyObj->municipality_id = $city->municipality_id;
$companyObj->city_id = $city->id;
$companyObj->address = $post["CabinetRegistrationForm"]["address"];
$companyObj->inn = $post["CabinetRegistrationForm"]["inn"];
$companyObj->approved = 0;
$companyObj->head_fio = $post["CabinetRegistrationForm"]["head_fio"];
$companyObj->phone = $post["CabinetRegistrationForm"]["phone"];
           
$companyObj->save();

<?= $form->field($model, 'last_name')->input('last_name') ?>      
<?= $form->field($model, 'email')->input('email') ?>
<?= $form->field($model, 'inn')->widget(SuggestionsWidget::class, [
      'token' => '*******************',

<?php if ($model->role == RoleModel::ROLE_RESEARCH_COORDINATOR_OO): ?>

一切似乎都是正确的，没有显示错误，$companyObj->errors- 一个空数组，但它$companyObj->save返回 false。数据库中没有新行。请帮帮我。

    你看，当你调用save()方法的时候，首先按照你在rules()中描述的规则对模型进行验证，如果一切正常，模型就飞到了数据库中。这意味着仍然存在验证错误。调用$companyObj->validate()方法，然后看看$companyObj->getErrors()是什么，会有错误，我保证)))

    顺便说一句，保存时可以禁用验证，$companyObj->save(false)

    我会重写控制器：

            $model = new Company();

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['view', 'id' => $model->id]);
        }

        return $this->render('update', [
            'model' => $model,
        ]);

    从控制器到模型的部分将被丢弃：

        /**
     * @inheritDoc
     */
    public function beforeValidate(): bool
    {
        $post = Yii::$app->request->post();

        $city = City::findOne(['name' => $post["CabinetRegistrationForm"]["city_name"]]);

        $this->activity = 1;
        $this->district_id = $city->district_id;
        $this->region_id = $city->region_id;
        $this->municipality_id = $city->municipality_id;
        $this->city_id = $city->id;
        $this->approved = 0;

        return parent::beforeValidate();
    }

    虽然这是你的基于表单数据的城市搜索，但xs不知何故是愚蠢的......封装也很难）拿它并替换你想要的数据）

    请记住，在 rules() 中，您只描述表单中的那些字段。具有 3 个字段的表单，在 rules() 3 个字段中，您描述，否则所有其他属性都可以替换为任何属性））））

    以及如何正确地将数据从 POST 写入模型？

    $model->load(Yii::$app->request->post()):

    • 从 post 将数据加载到模型中
    • 值将仅分配给 rules() 中描述的那些属性，其他所有内容都将被忽略。
    • 至于hiddenInput()包，xs，对我来说，它们应该被分配在模型的后台某处，但由于我已经这样做了，你需要在它们上面写额外的验证器，这样你就确定会有不可替代。
