I am trying to import a CSV into MYSQL database. I followed a tutorial here
Now i am getting an error that
The filetype you are attempting to upload is not allowed.
Below is my code for Controller :
function importcsv() {
$data['addressbook'] = $this->csv_model->get_addressbook();
$data['error'] = ''; //initialize image upload error array to empty
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'text/x-comma-separated-values'|'text/comma-separated-values'|'application/octet-stream'| 'application/vnd.ms-excel'|'application/x-csv'|'text/x-csv'|'text/csv'|'application/csv'|'application/excel'|'application/vnd.msexcel'|'text/plain';
$config['max_size'] = '1000';
$this->load->library('upload', $config);
// If upload failed, display error
if (!$this->upload->do_upload()) {
$data['error'] = $this->upload->display_errors();
$this->load->view('csvindex', $data);
} else {
$file_data = $this->upload->data();
$file_path = './uploads/'.$file_data['file_name'];
if ($this->csvimport->get_array($file_path)) {
$csv_array = $this->csvimport->get_array($file_path);
foreach ($csv_array as $row) {
$insert_data = array(
'firstname'=>$row['firstname'],
'lastname'=>$row['lastname'],
'phone'=>$row['phone'],
'email'=>$row['email'],
);
$this->csv_model->insert_csv($insert_data);
}
$this->session->set_flashdata('success', 'Csv Data Imported Succesfully');
redirect(base_url().'csv');
//echo "<pre>"; print_r($insert_data);
} else
$data['error'] = "Error occured";
$this->load->view('csvindex', $data);
}
}
public function chk_attachment() // callback validation for check the attachment extension
{
$file_type = array('.csv');
if(!empty($_FILES['uploaded_file']['name']))
{
$ext = strtolower(strrchr($_FILES['uploaded_file']['name'],"."));
if(in_array($ext,$ext_array))
{
return true;
}
else
{
$this->form_validation->set_message('chk_attachment','Attachment allowed only csv');
return false;
}
}
{
$this->form_validation->set_message('chk_attachment','image field is required');
return false;
}
}
The call back function was suggested by a user on stackoverflow who had same issue solved, but somehow didn't work for me. I have a users table and i just want to insert users using the uploaded CSV but somehow its not allowing me to upload a CSV.

Add $config['allowed_types'] = 'csv'; to your $config array.

Also go through the file on path application\config\mimes.php for more clear understanding about csv array support on file upload type
You can update this array if you really want...
'csv' => array('text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'application/x-csv', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel')
