unable to upload an excel file in codeigniter - codeigniter

Question

I have a Codeigniter project that can insert data into database through uploading an excel file and reading it with PHPExcel. It is working on my localhost however when I uploaded it in a LAMP server, It gives me an error The filetype you are attempting to upload is not allowed. How am I going to solve this?
EDIT
In my project, I also have a file image uploading..
public function uploadConfig(){
$this->load->library('PHPExcel');
$this->load->library('PHPExcel/IOFactory');
$config['upload_path'] = './csv_uploads/';
$config['allowed_types'] = 'xlsx|csv|xls';
$config['max_size'] = '10000';
$config['overwrite'] = true;
$config['encrypt_name'] = FALSE;
$config['remove_spaces'] = TRUE;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!is_dir('csv_uploads'))
{
mkdir('./csv_uploads', 0777, true);
}
// gif|jpg|jpeg|png
}
This works on my localhost in XAMPP. However, when I uploaded it on my LAMP server, it didn't work.

Answer 1

For The file type you are attempting to upload is not allowed this issue occur because of your file type is wrong or not fulfill.
Please apply below step to get your file type.
You can looking at system/libraries/Upload.php line 199:
$this->_file_mime_type($_FILES[$field]);
Update that line to:
$this->_file_mime_type($_FILES[$field]); var_dump($this->file_type); die();
Now you can see your actual file type Like xlsx or csv or xls or ods
Now you can add your file type below code
$config['allowed_types'] = 'xlsx|csv|xls';
also add in config/mimes.php

Codeigniter 3
add to your config/mimes.php types 'application/octet-stream'
'xlsx' => array('application/octet-stream','application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/vnd.ms-excel', 'application/msword', 'application/x-zip')
then it will work

Answer 3

Go to config/mimes.php -> lines no 32 (xls) -> add 'application/vnd.ms-office' into existing array.
'xls' => array('application/excel', 'application/vnd.ms-excel', 'application/msexcel', **'application/vnd.ms-office'**)
This work only for xls for any other type get the mime type and add into this array.

Answer 4

In your code
$config['allowed_types'] = 'xlsx|csv|xls';
But in Ubuntu it save file types is ods format. So it will never let allow to upload. add that
$config['allowed_types'] = 'xlsx|csv|xls|ods';
And in config/mimes.php
add this
'ods' => array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip'),
Provide Permeation to write in the folder
sudo chown apache:apache -R /var/www/html
and in php.ini
Check file_upload is on
and check max upload limit
as well as check max execution time

Answer 5

If you are using liberOffice or Open Office, You will face this problem. add "application/octet-stream" type in 'xlsx' to your application/config/mimes.php
'xlsx' => array('application/octet-stream','application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/vnd.ms-excel', 'application/msword', 'application/x-zip')

Answer 6

In Your Code Add Below Line
$config['allowed_types'] = '*';
$config['detect_mime'] = false;
this is configuration setting.
