Question

i’m trying to separate paypal config info from application/paypal_library file. Basically the config info are API_username, API_pwd, API_signiture etc.

The original structure is like this:

class Paypal_library {

    protected $ci;

    public $API_UserName = xxx;
    public $API_Password = xxx;
    public $API_Signature = xxx;
    ...
    ...
    function __construct() {
        $this->ci = & get_instance();
    }
    otherfunctions

so I move these variables in a new config file called config/paypal_config.php.
and put

$config['paypal_api_username'] =xxx;
$config['paypal_api_password'] = xxx;
$config['paypal_api_signature'] = xxx;

But i got a problem when i call this config file in paypal_library.php.
I used:

    protected $ci;

    $CI = & get_instance();
    $CI->config->load("paypal_config",TRUE);
    $config = $CI->config->item('paypal_config');

    public $API_UserName = $config['paypal_api_username'];
    public $API_Password = $config['paypal_api_password'];
    public $API_Signature = $config['paypal_api_signature'];
    ...
    ...
    function __construct() {
        $this->ci = & get_instance();
    }

But this doesn’t work, because it seems that i cannot put $CI=&get_instance() before constructor? However, if i put them inside constructor, paypal can’t find those variables during payment process.

so how can i implement paypal_config file here?

Thanks

You should set the properties in the constructor.

function __construct()
{
  $this->ci =& get_instance();
  $this->ci->load->config('paypal_config', TRUE);
  $config = $this->ci->config->item('paypal_config');

  $this->API_UserName = $config['paypal_api_username'];
  $this->API_Password = $config['paypal_api_password'];
  $this->API_Signature = $config['paypal_api_signature'];
}

A class can only contain method and property definitions.

The operations in your example before the API property definitions are syntactically incorrect and will cause a parse error.
