CodeIgniter: Excel file upload Error

Question

I am trying to upload excel file in CodeIgniter as i have specified below but it says invalid file. Is there a hidden issue with CodeIgniter or with my filetype specification?

$config['allowed_types'] = 'xls|xlsx';

Answer 1

I use this in my mime.php:

'xls'   =>  array('application/excel', 'application/vnd.ms-excel', 'application/vnd.ms-office', 'application/octet-stream', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/x-zip', 'application/vnd.ms-excel', 'application/msword'),
'xlsx'  =>  array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/x-zip', 'application/vnd.ms-excel', 'application/msword'),

Don't forget about 'application/vnd.ms-office'.

Answer 2

add this to your mimes.php also check your excel extention name

or you can use also

$config['allowed_types'] = '*';

'xlsx'  =>  array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip')

Answer 3

I Found this solution

'xlsx' => array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/x-zip', 'application/vnd.ms-excel', 'application/msword'),

'xls' => array('application/excel', 'application/vnd.ms-excel', 'application/octet-stream'),

Other solution by joni jones Uploading in Codeigniter - The filetype you are attempting to upload is not allowed

If you don't want to change system files. Just try this:

Open system/libraries/Upload.php (method do_upload() line 205) and do this:

var_dump($this->file_type);
exit();

Try to upload some file. Add file type, which you see in var_dump() to application/config/mimes.php . Little example: you have problem with .docx. Try to add:

'docx' => array('application/zip', 'application/msword', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document')

to application/config/mimes.php .

Answer 5

'xls' => array('application/excel', 'application/vnd.ms-excel', 'application/octet-stream'),

'xlsx' => array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/x-zip', 'application/vnd.ms-excel', 'application/msword'),
'xls' => array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/zip', 'application/x-zip', 'application/vnd.ms-excel', 'applica
    tion/msword'),

repalce with your previous mime type of xls and xlsx put the above code it can be work
