Why can i not upload images to my folder anymore? - php

Question

This was something I had working a few weeks back but after I made some changes to my view file images are now no longer being saved into my assets/uploads folder. I keep getting back the error - You did not select a file to upload. This is despite having made sure the path is definitely correct. What am i doing wrong here?
Here is my controller:
<?php
class HomeProfile extends CI_Controller
{
function HomeProfile()
{
parent::__construct();
$this->load->model("profiles");
$this->load->model("profileimages");
$this->load->helper(array('form', 'url'));
}
function upload()
{
$config['path'] = './web-project-jb/assets/uploads/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '10000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
$img = $this->session->userdata('img');
$username = $this->session->userdata('username');
$this->profileimages->putProfileImage($username, $this->input->post("profileimage"));
//fail show upload form
if (! $this->upload->do_upload())
{
$error = array('error'=>$this->upload->display_errors());
$username = $this->session->userdata('username');
$viewData['username'] = $username;
$viewData['profileText'] = $this->profiles->getProfileText($username);
$this->load->view('shared/header');
$this->load->view('homeprofile/homeprofiletitle', $viewData);
$this->load->view('shared/nav');
$this->load->view('homeprofile/upload_fail', $error);
$this->load->view('homeprofile/homeprofileview', $viewData, array('error' => ' ' ));
$this->load->view('shared/footer');
//redirect('homeprofile/index');
}
else
{
//successful upload so save to database
$file_data = $this->upload->data();
$data['img'] = base_url().'./web-project-jb/assets/uploads/'.$file_data['file_name'];
// you may want to delete the image from the server after saving it to db
// check to make sure $data['full_path'] is a valid path
// get upload_sucess.php from link above
//$image = chunk_split( base64_encode( file_get_contents( $data['file_name'] ) ) );
$this->username = $this->session->userdata('username');
$data['profileimages'] = $this->profileimages->getProfileImage($username);
$viewData['username'] = $username;
$viewData['profileText'] = $this->profiles->getProfileText($username);
$username = $this->session->userdata('username');
}
}
function index()
{
$username = $this->session->userdata('username');
$data['profileimages'] = $this->profileimages->getProfileImage($username);
$viewData['username'] = $username;
$viewData['profileText'] = $this->profiles->getProfileText($username);
$this->load->view('shared/header');
$this->load->view('homeprofile/homeprofiletitle', $viewData);
$this->load->view('shared/nav');
//$this->load->view('homeprofile/upload_form', $data);
$this->load->view('homeprofile/homeprofileview', $data, $viewData, array('error' => ' ' ) );
$this->load->view('shared/footer');
}
}
Here is my view:
<div id="maincontent">
<div id="primary">
<?//=$error;?>
<?//=$img;?>
<h3><?="Profile Image"?></h3>
<img src="<?php echo'$img'?>" width='300' height='300'/>
<?=form_open_multipart('homeprofile/upload');?>
<input type="file" name="img" value=""/>
<?=form_submit('submit', 'upload')?>
<?=form_close();?>
<?php if (isset($error)) echo $error;?>
</div>
</div>
Your help is much appreciated

The Codeigniter Upload class says "You did not select a file to upload" because it's looking for the key userfile in the $_FILES array.
From the docs: http://codeigniter.com/user_guide/libraries/file_uploading.html
$this->upload->do_upload()
Performs the upload based on the preferences you've set. Note: By
default the upload routine expects the file to come from a form field
called userfile... If you would like to set your own field name
simply pass its value to the do_upload function:
$field_name = "some_field_name";
$this->upload->do_upload($field_name)
So you have two choices, change
<input type="file" name="img">
to
<input type="file" name="userfile">
... or change
$this->upload->do_upload()
to
$this->upload->do_upload('img')
