How to upload a file in Yii2? , without a submission form?

Question

Yii

I'm doing a REST API, and I get no form with <?= $form->field($model, 'file')->fileInput() ?> The
question is how to save a file without a form? For example if I converted the base64 string to an image and saved it?
Or I generated a file and I had to save it.

Answer 1

how do you send data to the site?
if you use rest, then you obviously use the post and get and you obviously pass something there. what you pass there is the inputs. also send files

Answer 2

Of course you can. Read here abandon.ie/notebook/simple-file-uploads-using-jque... everything is very simply described here and with examples
