in controller
$file1 = $_FILES['po_file']['name'];
$file2 = $_FILES['in_file']['name'];
$config['upload_path'] = $pathToUpload;
$config['allowed_types'] = 'pdf';
$config['overwrite' ] =TRUE;
$config['max_size'] =0;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
echo $this->upload->display_errors();
// $this->load->view('file_view', $error);
}
else
{
$this->upload->do_upload(file1);

$file_name = $upload_data['file_name'];
}
I tried like this but it gave
You did not select a file to upload.
Any help how to do this???

Seeing your form in the question, I'm assuming that you want two files to be uploaded from two different input fields. Is that it ?
So, doing it in your way, your form should be as :
<form enctype="multipart/form-data" method="post"> <!-- enctype="multipart/form-data" is must, method 'post' or 'get' is depend on your requirement -->
<?php
if( !empty( $notification ) )
{
echo '
<p>Notifications : </p>
<p>'.$notification.'</p>'; <!-- For the status of the uploaded files ( error or success ) -->
}
?>
<label for="default">PO File</label>
<input type="file" name="po_file"> <!-- no need to add "multiple" attribute, unless you want multiple files to be uploaded in the same input field-->
<label for="default">Invoice File</label>
<input type="file" name="in_file">
<input type="submit" name="upload">
</form>
And your controller should be as :
class Image extends CI_Controller {
private $data; // variable to be used to pass status of the uploaded files ( error or success )
function __construct()
{
// some code
}
public function upload()
{
$this->data['notification'] = '';
if( $this->input->post('upload') ) // if form is posted
{
// setting the config array
$config['upload_path'] = 'uploads/'; // $pathToUpload ( in your case )
$config['allowed_types'] = 'pdf';
$config['max_size'] = 0;
$this->load->library('upload', $config); // loading the upload class with the config array
// uploading the files
$this->lets_upload( 'po_file' ); // this function passes the input field name from the form as an argument
$this->lets_upload( 'in_file' ); // same as above, function is defined below
}
$this->load->view('form', $this->data); // loading the form view along with the member variable 'data' as argument
}
public function lets_upload( $field_name ) // this function does the uploads
{
if ( ! $this->upload->do_upload( $field_name )) // ** do_upload() is a member function of upload class, and it is responsible for the uploading files with the given configuration in the config array
{
$this->data['notification'] .= $this->upload->display_errors(); // now if there's is some error in uploading files, then errors are stored in the member variable 'data'
}
else
{
$upload_data = $this->upload->data(); // if succesful, then infomation about the uploaded file is stored in the $upload_data variable
$this->data['notification'] .= $upload_data['file_name']." is successfully uploaded.<br>"; // name of uploaded file is stored in the member variable 'data'
}
}
}
Now suppose, you want a new image file to be uploaded in a different location or whatever, from the same form; then in the config array, you only have to change the array elements which you want to be different as :
$config['upload_path'] = '/gallery';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
Then you have to initialize the config array as :
$this->upload->initialize($config); // *** this is important ***
and then you have to load the upload class with this new config as :
$this->load->library('upload', $config);
and now you can call the lets_upload() function :
$this->lets_upload( 'img_file' );
in the upload() function.

Answer 2

first in your php.ini
file_uploads = On
Second be sure of that
<form action="controller/action" method="post" enctype="multipart/form-data">
third check that on codeigniter documentaion about upload file .
https://ellislab.com/codeigniter/user-guide/libraries/file_uploading.html
don't forget the extension of files allowd

Answer 3

If you see upload.php library file under system folder then you'll know that CI takes 'userfile' field name as default, So when you do
if ( ! $this->upload->do_upload())
{
echo $this->upload->display_errors();
// $this->load->view('file_view', $error);
}
//Passing parameter empty, then CI search for 'userfile'.
Try passing field name as you have done in else condition, or setting one of the input field name to 'userfile'.
