Laravel 5.4 file upload

I use Laravel 5.4 and want to upload image. But in controllrt $request->hasFile('pic') returns false. This is my blade.php :

.
.
.
<form action="" method="post">
    <input type="file" name="pic">
</form>
.
.
.

And this is my controller :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class myclass extends Controller {

    public function myfunc(Request $request) {
        if($request->hasFile('pic')){
            // never get this
        }
    }
}

Should i add another field to form or input in blade.php or controller?
