php - Laravel file upload validation doesn't trigger

i can upload files if fitting validation rule

'user_file' => 'file|max:10240|mimes:xls,xlsx,doc,docx,pdf,zip'

all goes fine.

i have set upload_max_filesize 32mb , post_max_size 40mb in php.ini

but if try upload file bigger 40mb validation rules don't trigger. tokenmismatchexception error....

if can verify trying upload big file (a video file example)

when exceed post payload size - dropped, csrf_token not come laravel , upload file empty cannot validated.

update

to fix need check file size before uploading javascript or jquery

here example:

CSS
