const url = "http://localhost/codeigniter/user/uploadExcel";

}

Answer 1

The file you're uploading is too large based on your php.ini settings:

upload_max_filesize = 2M
post_max_size = 2M

Increase those settings.

PHP will outright ignore the upload if the content-size header is larger then your server configuration, and thus the $_FILES array will be empty. Which is very annoying, because it makes it very hard to report on what file failed when your application allows multiple files to be uploaded at once via AJAX.
