yii2.0 控制器方法 视图表单 Form表单处理

假设我们在ArticleController.php下面的actionForm方法中来处理提交的表单

新建立一个 views/Article/article-form.php文件用来作为输入表单

<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
?>
<?php $form = ActiveForm::begin(); ?>

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

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

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

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

新建立一个 views/Article/article-confirm.php文件用来显示表单处理成功后的结果

<?php
use yii\helpers\Html;
?>
<p>You have entered the following information:</p>

<ul>
<li><label>Name</label>: <?= Html::encode($model->title) ?></li>
<li><label>Email</label>: <?= Html::encode($model->content) ?></li>
</ul>

需求：提交过来的数据需要验证--title、content不能为空

新建models/ArticleForm.php

<?php

namespace app\models;

use yii\base\Model;

class ArticleForm extends Model
{
public $title;
public $content;

public function rules()
{
return [
[['title', 'content'], 'required'],
//['email', 'email'],
];
}
}

最后在ArticleController.php中完成actionForm方法

public function actionForm()
{
$model = new ArticleForm;
if ($model->load(Yii::$app->request->post()) && $model->validate())
{
// 验证 $model 收到的数据
// 做些有意义的事 ...
return $this->render('article-confirm', ['model' => $model]);
}
else
{
// 无论是初始化显示还是数据验证错误
return $this->render('article-form', ['model' => $model]);
}
