Image uploading in codeigniter in database - php

Question

I have a problem with uploading images in the database in codeigniter. When I upload image in the database, it shows this type of error like:
The upload path does not appear to be valid. So what's the problem in this code. I cannot figure out, so please help me.
I tried base_url() method also but error is not solved...!

}
my Model:-
class useradd extends CI_Model
{
function addstudent($data)
{
$result = $this->db->insert('add_student', $data);
}
}
My error is:
The upload path does not appear to be valid.

Try This Code To Upload Image.and remove form tag in your view file and you didn't define form_close method at the end of the form of your view file
$file = $_FILES['filename']['name'];
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
$this->upload->do_upload();
$allData = $this->upload->data();
