File uploading issue in Yii2

Question

I am developing an application in Yii2 framework.

I am uploading an image using code below and which has worked perfect till now. But now I got an error instant. I don't understand what has happened.

Below is the code of controller where upload file and save take place:

// Upload photo of subcategories...
$model->file = UploadedFile::getInstance($model, 'file');
if($model->file) {
    $imageName = rand(1000,100000);
    $model->file->saveAs('uploads/subcategories/'.$imageName.'.'.$model->file->extension);
    $model->sub_category_photo = 'uploads/subcategories/'.$imageName.'.'.$model->file->extension;
}
$model->save();

I got below error:

PHP Warning – yii\base\ErrorException finfo_file(C:\xampp\tmp\php9A7B.tmp): failed to open stream: No such file or directory

I also un-comment extension = fileinfo.dll in php.ini file and restart server.

Does the directory tmp exist and is accessible? Is the fileinfo.dll extension now enabled or disabled? — robsch

And you haven't changed anything on your code? What else have you done? — robsch

Then it has probably nothing to do with Yii, I guess. Anything else? No harddisk space left? Anyone else that has changed anything on the machine? System updates? — robsch

I got solutions of this questions.

Call $model->save(); in controller

before

$model->file->saveAs();

Means in above code of my questions changed to below

// Upload photo of subcategories...
$model->file = UploadedFile::getInstance($model, 'file');
if($model->file) {
    $imageName = rand(1000,100000);
    $model->sub_category_photo = 'uploads/subcategories/'.$imageName.'.'.$model->file->extension;
    $model->save();
    $model->file->saveAs('uploads/subcategories/'.$imageName.'.'.$model->file->extension);
} else {
    $model->save();
}

Hope this help someone as it helped me and I found answer from here

In views > _form.php

<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model, 'image')->fileInput() ?>
<?php ActiveForm::end(); ?>

In controller:

use yii\web\UploadedFile;

In actionCreate():

if ($model->load(Yii::$app->request->post())){
    $model->image = UploadedFile::getInstance($model, 'image');            
    if($model->validate() && $model->save()) {                 
        $model->image->saveAs(dirname(__FILE__).'/../../uploads/'. $model->image);   
        $model->save(); 
    }
}

In actionUpdate():

if ($model->load(Yii::$app->request->post()) ) {           
    $model->image = UploadedFile::getInstance($model, 'image');
    if($model->validate() && $model->save()){
        $model->image->saveAs(dirname(__FILE__).'/../../uploads/'.$model->image);   
        $model->save();
    }
}

In actionDelete($id):

unlink($_SERVER["DOCUMENT_ROOT"]."/../../uploads/".$model->image);

//Model Rule (note skip on empty):
['file', 'file', 'extensions' => 'jpg, jpeg, gif, png', 'mimeTypes' => 'image/jpeg, image/gif, image/png', 'skipOnEmpty' => true],

//save file
$model->file->saveAs();

//set it to null
$model->file = null;

//now it will save ok
$model->save();

I think what happens is once the file is saved, it's cleared out of memory so when the model tries to save it throws an error.
