Codeigniter File Upload Not Functioning - codeigniter

Question

I'm having problems trying to implement the Codeigniter class in my application. The issue is that when I submit my form, the function that executes is not saving the file to my specified folder and it is not throwing an error message. My code is as follows:
View:
<?php echo form_open_multipart('requests/submit_candidate'); ?>
<table>
<tr>
<td><label for="text">Upload CV</label></td>
<td><input type="file" name="file"></textarea></td>
</tr>
<tr>
<td><label for="text">Extra Information</label></td>
<td><textarea name="extra_info"></textarea></td>
</tr>
</table>
<input type="submit" name="submit" value="Submit" />
</form>
Controller:
public function submit_candidate($slug)
{
$this->load->library('upload');
$config = array(
'upload_path' => dirname($_SERVER["SCRIPT_FILENAME"])."/uploads/",
'upload_url' => base_url()."uploads/",
'allowed_types' => "gif|jpg|png|jpeg|pdf|doc|xml",
'overwrite' => TRUE,
'max_size' => "1000KB",
'max_height' => "768",
'max_width' => "1024"
);
if($this->upload->do_upload($config))
{
echo "file upload success";
}
else
{
echo "file upload failed";
}
}
Can anybody help please?
Many thanks,

Try this if it works for you:
1) HTML
<td><input type="file" name="file"></td>
2) Controller
public function submit_candidate($slug)
{
$this->load->library('upload');
$config = array(
'upload_path' => "./uploads/",
//'upload_url' => base_url()."uploads/",
'allowed_types' => "gif|jpg|png|jpeg|pdf|doc|xml",
'overwrite' => TRUE,
'max_size' => 1000,
'max_height' => 768,
'max_width' => 1024
);
$this->upload->initialize( $config );
if(!$this->upload->do_upload('file')) // "file" is the name of the element default it's "userfile"
{
print_r( $this->upload->display_errors() );die; //display the error
}
else
{
$data = $this->upload->data();
print_r( $data );die; //file uploaded data
}
}
1) Inside the function you need to give the name of the form file element ( for you its "file" )
2) You have also used a config variable "upload_url" which is invalid.
3) You need to initialize the config for upload library.
Here (File Upload Documentation) is the reference for you.
