php - How to Access $this variable inside nested functions in codeigniter?
Get the solution ↓↓↓
Solution:
You are going wrong about the whole concept. PHP is not Javascript.You shouldn't nest functions, specially not when using OOP frameworks. If you run function index twice, the second time you will probably get an error that function buy is already declared since first run of index will declare function buy.
I would declare them as class member functions / methods.
class Webservice extends CI_Controller {
function __construct()
{
parent::construct();
$this->load->library('encrypt');
$this->load->model('MWSDl');
}
function index()
{
// do something like
$apicode = 'xxxxxx';
$this->buy($apicode);
//or what ever else you need to do
}
function buy($apicode)
{
if(!$this->MWSDl->check_gateway($apicode)) {
$this->nusoap_server->service(file_get_contents("php://input"));
}
}
}
No need to use globals in codeigniter.
Let me know if this helps.
Answer
Solution:
I understand your question. I also had the same problem with nusoap. When registering a service you have to make a function. Thus in CI you are creating it inside a class function which makes the service function is nested inside, and cannot be taken outside.
Why don't you try this below? I use it all the time before, with helper etc. It's simple and I have tried it and it works.
Put this inside your nested function: $ci =& get_instance();
and the rest you have to replace $this with $ci eq. $ci->some_model->some_function(); or $ci->some_var = 'something';
And it also work if you tried to call a db.
I hope this will help you.
