CodeIgniter - Uploading an Image through a form, store the location of the image in database

问题

I'm trying to upload an image to my site through a form, however it's much more efficient to (rather than bog down the database) just store the location of the image in the database.

I'm having trouble with my form and really don't know where to go:

<?=form_open('bro/submit_new');?>
 //other form data
 Image: <input type="file" name="image" size="20" /> <br>
 <input type="submit" value="Submit" />
</form>

Now the form itself works fine, the problem is that it's trying to store the image into the database field 'image' (which is type TEXT). What's the easiest way to tell it to just store the file, and give the file location to store in the 'image' field? (I tell it where to upload the file via the controller).

Thanks

Edit: controller code (for this part):

function submit_new(){
    $config['upload_path'] = './images/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '2000';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';     
    $this->load->library('upload', $config);

    $this->db->insert('post', $_POST);

    redirect('bro');
}

CodeIgniter's file uploading class will do this for you. The entry in their user guide explains as well as I could, so I'm going to point you there.

Essentially you'd just need to modify the controller that they have there to include a bit where you put the file URL in the database, which you can accomplish easily by using $this->upload->data() and extracting [full_path] from the resulting array, and then sending it to a model which handles the database input.
