missing id passed in urlindent - php

Question

I am trying to upload file on server and to view the file uploaded I have to pass the model id to the view action. It is all good untill I add
'options' => ['enctype'=>'multipart/form-data']
to my ActiveForm. After I add it the id passed to the action view by URL doesn't show anymore and I get missing parameter message.
i am using yii 2.0.2
Create action:
public function actionCreate()
{
$model = new SubContent();
if ($model->load(Yii::$app->request->post()) ) {
//$fileName = $model->id;
$model->save();
$fileName = $model->id;
$files =UploadedFile::getInstance($model,'files');
$files->saveAs( 'uploads/'.$files->getBaseName().'.'.$files->getExtension());
$model->files=$files;
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
Form:
<div class="sub-content-form">
<?php $form = ActiveForm::begin(['options' => ['enctype'=>'multipart/form-data']]); ?>
<?= $form->field($model, 'files')->fileInput(['maxlength' => 255]) ?>
<?= $form->field($model, 'sub_id')
->dropDownList(ArrayHelper::map(Subjects::find()
->where(['year'=>\Yii::$app->user->identity->year])
->all(),'id','sub_name'),
['prompt'=>' select subject']
) ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
and this is my model
<?php
namespace frontend\models;
use Yii;
/**
* This is the model class for table "sub_content".
*
* #property integer $id
* #property string $files
* #property integer $sub_id
*
* #property Subjects $sub
*/
class SubContent extends \yii\db\ActiveRecord
{
/**
* #inheritdoc
*/
public static function tableName()
{
return 'sub_content';
}
public function rules()
{
return [
[['files', 'sub_id'], 'required'],
[['sub_id'], 'integer'],
[['files'], 'string', 'max' => 255]
];
}
public function attributeLabels()
{
return [
'id' => 'ID',
'files' => 'Files',
'sub_id' => 'Sub ID',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getSub()
{
return $this->hasOne(Subjects::className(), ['id' =>
'sub_id']);
}
}
edited..... still didnt work

First of all - since 2.0.8 you don't have to add enctype, it's done automatically when you add fileInput field.
You are not verifying if $model->save() returned true and it looks like that model did not pass validation and because of that $model is not saved and because of that $model->id is not set.
You should do something like:
public function actionCreate()
{
$model = new SubContent();
if ($model->load(Yii::$app->request->post()) ) {
$model->files = UploadedFile::getInstance($model,'files');
if ($model->save()) {
$model->files->saveAs('uploads/' . $files->getBaseName() . '.' . $files->getExtension());
return $this->redirect(['view', 'id' => $model->id]);
}
}
return $this->render('create', ['model' => $model]);
}
For this to work you need to set proper validation rules in SubContent model.
