Yii2:仅在触发时自动填写表单

<?php
use yii\widgets\ActiveForm;
?>

<?php $form = ActiveForm::begin(); ?>

<?= $form->field($model, 'name')->textInput() ?>

<?= $form->field($model, 'email')->textInput() ?>

<button type="submit" class="btn btn-primary">提交</button>

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

<?php
namespace app\controllers;

use Yii;
use yii\web\Controller;
use app\models\MyForm;

class MyController extends Controller
{
    public function actionIndex()
    {
        $model = new MyForm();

        if ($model->load(Yii::$app->request->post()) && $model->validate()) {
            // 在这里进行表单数据的处理
            // 可以根据需要填写表单的字段
            $model->field1 = '自动填写的值1';
            $model->field2 = '自动填写的值2';
        }

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