Answer 1

i recenly got that problem and solve it. you can check is module fileinfo in php already on? if you can access to CPanel, you can go to SOFTWARE TAB then search Select PHP Version, then you can see list of module and check that module fileinfo. and try to upload again.

Answer 2

At your PHP change

$this->upload->do_upload()

to

$this->upload->do_upload("add_1")

where "add_1" is your input name attribute.

Codeigniter UPLOAD library docs

P.S. At your HTML the Label attribute for="" is targeting input ID so you have to add id to your input.
