使用Yii框架实现表单提交和处理的步骤

<?php
    use yiiwidgetsActiveForm;
    use yiihelpersHtml;
?>

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

    <?= $form->field($model, 'name')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'email')->textInput(['maxlength' => true]) ?>

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

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

<?php

namespace appcontrollers;

use Yii;
use appmodelsFormModel;
use yiiwebController;

class FormController extends Controller
{
    public function actionIndex()
    {
        $model = new FormModel();

        if ($model->load(Yii::$app->request->post()) && $model->validate()) {
            // 表单提交后的处理逻辑
            // ...
            return $this->render('success');
        }

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

    public function actionSuccess()
    {
        return $this->render('success');
    }
}

<?php

namespace appmodels;

use yiiaseModel;

class FormModel extends Model
{
    public $name;
    public $email;

    public function rules()
    {
        return [
            [['name', 'email'], 'required'],
            ['email', 'email'],
        ];
    }
}

'components' => [
    // ...
],
'controllerMap' => [
    'form' => 'appcontrollersFormController',
],
