Question

我有3个相似的页面，分别是页面A，页面B和页面C。所有这些页面都是为了创建新数据。

如果还使用页面怎么办？

想法是这样的：

Controller.php

Page A ----> actionCreate() -----> render to 'create'
Page B ----> actionCreate() -----> render to 'create-obituary'
Page C ----> actionCreate() -----> render to 'create-anniversary'

问题是，我希望所有这三个页面仅使用一个控制器（即actionCreate（））。这意味着我想对所有这3页（A，B和C页）进行其他操作。

我建议将一些参数传递给操作：

public function actionCreate($type = 'create')
{
    $typeToPageMapping = [
        'create' => 1,
        'departed' => 8,
        'anniversary' => 4,
    ]

    $model = new Memoriam(['scenario'=>'create']);
    if ($type == 'anniversary') {
        $modelAnn = new Anniversary();
    }

    if ($model->load(Yii::$app->request->post()) && ($type != 'anniversary' || $modelAnn->load(Yii::$app->request->post()))) {
        $model->picture1 = UploadedFile::getInstance($model, 'picture1');
        if ($model->validate()) {
            $model->picture1 = $this->savePicture($model);
            $model->page = $typeToPageMapping[$type];
            $model->save();
            if ($type == 'anniversary') {
                $modelAnn->decease_id = $model->ID;
                $modelAnn->save();
            }    
            if($model->save(false)){
                return $this->redirect(['site/profile', 'id' => $model->ID]);
            }
        }
    }

    return $this->render('create', [
        'model' => $model,
        'type' => $type,
        'anniversary' => $modelAnn ?? null,
    ]);
}

protected function savePicture($model)
{
    $session = Yii::$app->session;
    if($model->picture1 == null) {
        return null;
    }

    $dir = "img/".$session['UserID']."/memoriam/";

    if(!file_exists($dir)) 
    {
        $old = umask(0);
        mkdir($dir, 0777, true);
        umask($old);
    }
    $path = md5(date("YmdHis")) . '.' . $model->picture1->extension;
    $model->picture1->saveAs($dir.$path);
    return $path;
}

if yii2页面的其他操作
