Question

我是yii的新手，致力于创建简报应用程序。为此，我使用的是yii2.0高级模板。我已经通过gii CRUD生成了控制器模型和表单。我有一个带有图像上传的创建表单（_form.php），当我提交此表单时，它将转到我的控制器中的actionCreate（）并且它没有进入if（$ model-＆gt; load（Yii :: $ app-＆gt） ; request-＆gt; post（））＆amp;＆amp; $ model-＆gt; save（））{in actionCreate（）。我必须将表单数据保存到数据库中。我有很多谷歌，并没有找到任何适合我的解决方案。

My Controller
namespace frontend\controllers;

use Yii;
use frontend\models\Newsletter;
use yii\data\ActiveDataProvider;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;

/**
 * NewsletterController implements the CRUD actions for Newsletter model.
 */
class NewsletterController extends Controller
{
    public function behaviors()
    {
        return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [
                    'delete' => ['post'],
                ],
            ],
        ];
    }

    /**
     * Lists all Newsletter models.
     * @return mixed
     */
    public function actionIndex()
    {
        $dataProvider = new ActiveDataProvider([
            'query' => Newsletter::find(),
        ]);

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

    /**
     * Displays a single Newsletter model.
     * @param integer $id
     * @return mixed
     */
    public function actionView($id)
    {
        return $this->render('view', [
            'model' => $this->findModel($id),
        ]);
    }

    /**
     * Creates a new Newsletter model.
     * If creation is successful, the browser will be redirected to the 'view' page.
     * @return mixed
     */
    public function actionCreate()
    {
        $model = new Newsletter();

        if ($model->load(Yii::$app->request->post()) && $model->save()) {

            return $this->redirect(['view', 'id' => $model->id]);
        } else {
            return $this->render('create', [
                'model' => $model,
            ]);
        }
    }

My Model:

<?php

namespace frontend\models;

use Yii;
use yii\web\UploadedFile;

/**
 * This is the model class for table "newsletter".
 *
 * @property integer $id
 * @property string $title
 * @property integer $bulletin_id
 * @property string $image
 * @property string $url
 * @property string $created
 */
class Newsletter extends \yii\db\ActiveRecord
{
    public $image;
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'newsletter';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['title', 'bulletin_id', 'image', 'url'], 'required'],
            [['bulletin_id'], 'integer'],

            [['title', 'url'], 'string', 'max' => 100],
            [['image'], 'safe'],
            [['image'], 'file', 'extensions'=>'jpg, gif, png'],
            [['created'], 'safe'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
    //echo "labels";
    //exit;
        return [
            'id' => 'ID',
            'title' => 'Title',
            'bulletin_id' => 'Bulletin ID',
            'image' => 'Image',
            'url' => 'Url',
            'created' => 'Created',
        ];
    }
}

my _form.php

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;
//use kartik-v\yii2-widgets\FileInput;

/* @var $this yii\web\View */
/* @var $model frontend\models\Newsletter */
/* @var $form yii\widgets\ActiveForm */
?>

<div class="newsletter-form">

    <?php $form = ActiveForm::begin(['options' => ['enctype'=>'multipart/form-data']]); ?>

    <?= $form->field($model, 'title')->textInput(['maxlength' => 100]) ?>

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

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

    <?= $form->field($model, 'url')->textInput(['maxlength' => 100]) ?>


    <div class="form-group">
        <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
    </div>

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

</div>

请让我知道我哪里出错了

Answer 1

您实际上并未在控制器中获取该文件。您需要获取该文件，然后对其执行操作。

按照此处的说明操作：https://github.com/yiisoft/yii2/blob/master/docs/guide/input-file-upload.md

表格数据未在yii2.0高级模板中保存？
