How to upload image file

[eluser]Shahgeb[/eluser]
simply at validation rule call the call back function
like

$rule['image_field_name'] = callback_verfiy_image();


and verfiy_image function sould be in controller
verfiy_image()
{
if(empty($_FILES['image_field_name']['name']['0'])){
$this->validation->set_message('verfiy_image', "You must have to specifiy image");
return false;
}

}

or any custom message which you want to show in set_message function


hopes it will work
