How to create a directory inside a directory in yii2 and upload file into that directory

Question

I have a form

  <?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
 <?php echo $form->field($userformmodel, 'user_image')->fileInput(); ?>
 <?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?>
 <?php ActiveForm::end(); ?>

I am uploading a file in the form and submit

In the model I have written the code as

 public function rules()
{
    return [
        [['user_image'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg']
    ];
}

 public function upload()
{
    if ($this->validate()) {
        $this->user_image->saveAs('uploads/' . $this->user_image->baseName . '.' . $this->user_image->extension);
        return true;
    } else {
        return false;
    }
}

In my controller

 public function actionProfile()
{
 $model = new UserProfile();
 $userformmodel = new UserForm();
 $model->user_image = UploadedFile::getInstance($userformmodel, 'user_image');
 if($model->save(false))
                {
                $model->upload();        
                }
 }

This is just creating a directory called uploads. But I want to create a directory inside uploads directory for each user i.e, based upon the primary key in database table user I want to create and name the directory name.

Example, if the user registering is saved as primarykey 4, then a directory with name 4 must be created and the file he uploads must be saved into that directory.

How to make this happen? please help.

In yii2, you can use 'yii\helpers\FileHelper' to create folders.

FileHelper::createDirectory($path, $mode = 0775, $recursive = true);

In your case:

public function upload()
{
    if ($this->validate()) {
        $path = 'uploads/'. USERNAMEHERE .'/'. date('YMD');
        FileHelper::createDirectory($path);
        $this->user_image->saveAs($path .'/'. $this->user_image->baseName . '.' . $this->user_image->extension);
        return true;
    } else {
        return false;
    }
}
