YII2 - 如何从表单中获取字段值以进行搜索

Question

I am a new in Yii2 and in MVC, so think that answer to question is simple, but did not found the answer from documentation and tutorials. So, I need to select a record with corresponding id from the database table. So, here the steps that I am following:

1) I created a model (CustomerReport) with CRUD generator for corresponding table and added it on the view where :

use app\models\CustomerReport;

2) On the view page I had tested it with

$customer_data = CustomerReport::findone(['id' => 2]);

This works OK for me

3) I added a Search form on the view:

<?php $form = ActiveForm::begin(['id' => 'customer-report']); ?>
                <?= $form->field($model, 'id') ?>

                <div class="form-group">
                    <?= Html::submitButton('Submit', ['class' => 'btn btn-primary', 'name' => 'contact-button']) ?>
                </div>

            <?php ActiveForm::end(); ?>

But I could not find the way to perform a search by id via form. As I understand, I need to provide search field value into

$customer_data = CustomerReport::findone(['id' => VALUE FROM ACTIVE FORM]);

Answer 1

Controller知道视图搜索表单返回的对象中的内容

$customer_data = CustomerReport::findone(['id' => $model->id]);

Answer 2

In your file where these form get POSTed (probable XyzController.php)

if(isset($_POST['CustomerReport']['id'])  // after form get POSTed
    $customer_data = CustomerReport::findone(['id' => $_POST['CustomerReport']['id']]);
