Hello dear, I want to expose a problem that I am having in one of my forms, the truth is that I have been with Yii2 for a few years, but I must be burned, it is rare and I can’t really find the solution. I summarize:
I have a form where I must also save two images, one of the front of a package and the back of it. I have already worked with images in the past, I use the kartik-v fileinput plugin. In fact I have it in other forms in the same application. From the front, I mean from the view, it allows me to select the images, but by giving it to save and review in the controller the array $_FILES does not bring anything, it comes empty, now, if I occupy the original input files of yii2. It leaves me perfectly, brings me the files. I have tried everything, put the plugin without configuration, without validation, with validation, various configurations, the strange thing is that the same configuration in another form works.
I am going to show my code to see if any one can give me a little light, I show the form and I show the controller along with the capture of the empty array and the array with data. I hope you can collaborate with me in this roll that I cannot advance. I thank you very much!
I use Yii2 version 2.0.30 over php 7.2.24 on linux mint.
I clarify that I have changed some names of entities for confidentiality with the client.

_controller:
In the controller I have more code, but I think it is enough to get an idea of the work.
public function actionCreate()
{
$model = new Cabel();
if ($model->load(Yii::$app->request->post()) && $model->validate())
{
echo '<pre>';
print_r($_FILES);
echo '</pre>';
exit();
$model->file_1 = UploadedFile::getInstance($model, 'file_1');
$model->file_2 = UploadedFile::getInstance($model, 'file_2');
}
}
Instead if I use the inputs from yii2 it brings them to me, look:
