Yii2中如何管理用戶投訴與建議

在Yii2框架中，管理用戶投訴和建議可以通過創建一個專門的控制器和視圖來實現。以下是一個簡單的示例，展示了如何實現這一功能：

1. 創建一個新的控制器（例如：ComplaintsController.php）：

<?php

namespace app\controllers;

use yii\web\Controller;
use app\models\Complaint;

class ComplaintsController extends Controller
{
    public function actionIndex()
    {
        $complaints = Complaint::find()->all();
        return $this->render('index', [
            'complaints' => $complaints,
        ]);
    }

    public function actionCreate()
    {
        $model = new Complaint();

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

    public function actionView($id)
    {
        $complaint = Complaint::findOne($id);
        return $this->render('view', [
            'complaint' => $complaint,
        ]);
    }

    public function actionUpdate($id)
    {
        $complaint = Complaint::findOne($id);

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

    public function actionDelete($id)
    {
        $complaint = Complaint::findOne($id);
        if ($complaint->delete()) {
            return $this->redirect(['index']);
        } else {
            return $this->error('無法刪除投訴.');
        }
    }
}

2. 創建一個新的模型（例如：Complaint.php）：

<?php

namespace app\models;

use yii\db\ActiveRecord;

class Complaint extends ActiveRecord
{
    public static function tableName()
    {
        return 'complaints';
    }

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

    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'name' => '姓名',
            'email' => '郵箱',
            'description' => '投訴描述',
        ];
    }
}

3. 創建視圖文件（例如：views/complaints/_form.php）：

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

/* @var $model app\models\Complaint */
?>

<div class="complaint-form">

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

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

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

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

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

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

</div>

4. 創建視圖文件（例如：views/complaints/index.php）：

<?php

/* @var $this yii\web\View */
/* @var $complaints app\models\Complaint[] */

$this->title = '投訴和建議';
?>

<h1>投訴和建議</h1>

<p>以下是我們的用戶提交的投訴和建議：</p>

<?= \yii\grid\GridView::widget([
    'dataProvider' => new \yii\data\ActiveDataProvider([
        'query' => $complaints,
    ]),
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],

        'id',
        'name',
        'email',
        'description',

        ['class' => 'yii\grid\ActionColumn',
            'template' => '{view} {update} {delete}',
        ],
    ],
]); ?>

5. 創建視圖文件（例如：views/complaints/view.php）：

<?php

/* @var $this yii\web\View */
/* @var $complaint app\models\Complaint */
?>

$this->title = '查看投訴和建議';
$this->params['breadcrumbs'][] = ['label' => '投訴和建議', 'url' => ['index']];
$this->params['breadcrumbs'][] = ['label' => $complaint->name, 'url' => ['view', 'id' => $complaint->id]];
?>

<h1>查看投訴和建議 #<?= $complaint->id ?></h1>

<p><strong>姓名:</strong> <?= $complaint->name ?></p>
<p><strong>郵箱:</strong> <?= $complaint->email ?></p>
<p><strong>描述:</strong> <?= $complaint->description ?></p>

6. 創建視圖文件（例如：views/complaints/create.php）：

<?php

/* @var $this yii\web\View */
/* @var $model app\models\Complaint */
?>

$this->title = '創建投訴和建議';
$this->params['breadcrumbs'][] = ['label' => '投訴和建議', 'url' => ['index']];
$this->params['breadcrumbs'][] = '創建';
?>

<h1>創建投訴和建議</h1>

<?= $this->render('_form', [
    'model' => $model,
]) ?>

7. 創建視圖文件（例如：views/complaints/update.php）：

<?php

/* @var $this yii\web\View */
/* @var $complaint app\models\Complaint */
?>

$this->title = '更新投訴和建議';
$this->params['breadcrumbs'][] = ['label' => '投訴和建議', 'url' => ['index']];
$this->params['breadcrumbs'][] = ['label' => $complaint->name, 'url' => ['view', 'id' => $complaint->id]];
$this->params['breadcrumbs'][] = '更新';
?>

<h1>更新投訴和建議 #<?= $complaint->id ?></h1>

<?= $this->render('_form', [
    'model' => $complaint,
]) ?>

通過以上步驟，您可以在Yii2框架中管理用戶投訴和建議。用戶可以通過表單提交投訴和建議，然后在后臺查看和管理這些信息。
