Question

如何在上传文件后将用户重定向到视图页面？

现在它只在我在视图中写入db条目的id

时才有效

我是php和yii 2的新手。

控制器

   public function actionUpload()
    {
        $model = new UploadForm();
        if (Yii::$app->request->isPost) {
            $model->file = UploadedFile::getInstance($model, 'file');
            if ($model->file && $model->validate()) { 
                $postFile   = Yii::$app->request->post();           
                $directory = Yii::getAlias('@frontend/web/uploads');
                $uid = Yii::$app->security->generateRandomString(6);
                $fileName = $uid . '.' . $model->file->extension;
                $filePath = $directory . '/' . $fileName;
                $path = 'http://frontend.dev/uploads/' . $fileName;
                $userinfo = new webminfo();
                $userinfo->uid = $uid;
                $userinfo->author_id = Yii::$app->user->id;
                $userinfo->path = $filePath;
                $userinfo->url = $path;
                $userinfo->created_at = time();
                $userinfo->ip = Yii::$app->getRequest()->getUserIP();
                $userinfo->save();
                if ($model->file->saveAs($filePath)) {
                    Yii::$app->session->setFlash('success', 'Success');
             return $this->redirect(['view', 'id' => $userinfo->uid]);             
               }   
            }
                else {
                    Yii::$app->session->setFlash('error', 'Error');
                }
        }
        return $this->render('upload', ['model' => $model]);
    }

public function actionView($id) {
    $model = new webminfo();

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

查看

<?php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
use yii\helpers\Url;
use app\models\webminfo;
$this->title = 'View';
$this->params['breadcrumbs'][] = $this->title;

?>

在重定向功能

中使用$uid代替$userinfo->uid，如下所示

return $this->redirect(['view', 'id' => $uid]);
