Upload images in Codeigniter - php

Question

I'm new to Codeigniter and I'm having problem with image upload function.
Error says - You did not select a file to upload.
Can anyone check my code and tell me what to do?
THIS IS MY CONTROLLER
This is my Controller which processes data.
public function add_data() {
$this->load->view('admin/header.php');
$this->load->library('form_validation');
$this->form_validation->set_rules('name', 'name', 'required');
$this->form_validation->set_rules('price', 'price', 'required');
$this->load->helper(array('form', 'url'));
if ($this->form_validation->run() == TRUE)
{
$this->load->view('admin/add_view.php');
$config['upload_path'] = './files/';
$config['allowed_types'] = 'jpg';
$this->load->library('upload', $config);
$this->upload->do_upload('picture');
$this->upload->data();
$data = array(
'name' => $this->input->post('name'),
'info' => $this->input->post('info'),
'gorod' => $this->input->post('gorod'),
'price' => $this->input->post('price'),
'amount' => $this->input->post('amount'),
'age' => $this->input->post('age'),
'status' => $this->input->post('status'),
'minbal' => $this->input->post('minbal'),
'contacts' => $this->input->post('contacts'),
'email' => $this->input->post('email'),
'alias' => $this->input->post('alias'),
'filename' => $this->input->post('picture')
);
$this->Adminmodel->add_record($data);
}
else
{
$this->load->view('admin/formnotsuccess');
}
}

Answer 1

You are missing
enctype="multipart/form-data" in form
Read php file upload
And Upload code should be like bellow. Its easy to track your errors
if(!$this->upload->do_upload()) # do_upload('picture');
{
echo $this->upload->display_errors();
}
else
{
$data = $this->upload->data();
print_r($data);
}
