picture upload in codeigniter - image

Question

Everything is fine, but when I open the upload folder there is not any image.
here is the controller "admin_news". I try to upload the image file in localhost/site/asset/upload. But when i click submit only the information(title, news and category) goes into datebase, but the file is not uploaded.
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'html', 'file'));
$config['upload_path'] = base_url('asset/upload/');
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
}
public function add_news(){
$this->load->helper('form');
$this->load->model('AddNews');
$this->load->view('templates/header', $data);
$this->load->view('admin/add_news');
$this->load->view('templates/footer');
if($this->input->post('submit')){
if ($this->upload->do_upload('image'))
{
$this->upload->initialize($config);
$this->upload->data();
}
$this->AddNews->entry_insert();
redirect("admin_news/index");
}
}
The view has only:
<?php echo form_open_multipart(''); ?>
<input type="text" name="title" value="Title..." onfocus="this.value=''" /><br />
<input type="file" name="image" /><br />
....

Answer 1

This should not be a URL:
$config['upload_path'] = base_url('asset/upload/');
It should be a path to somewhere on your server, either a full absolute path or a relative one (all paths in Codeigniter are relative from index.php).
Use either one of these:
// Full path
$config['upload_path'] = FCPATH.'asset/upload/';
// Relative
$config['upload_path'] = './asset/upload/';
One more thing:
if ($this->upload->do_upload('image'))
{
// You don't need this, and besides $config is undefined
// $this->upload->initialize($config);
// You don't seem to be doing anything with this?
$this->upload->data();
// Move this here in case upload fails
$this->AddNews->entry_insert();
redirect("admin_news/index");
}
// Make sure to show errors
else
{
echo $this->upload->display_errors();
}

I think in your code, problem is you have declared configuration after do_upload method
if ($this->upload->do_upload('image'))
{
$this->upload->initialize($config);
$this->upload->data();
}
configuration should be initialized before use the method. I think that was the problem. so you have to do configuration before the do_upload method
