Card Present PHP SDK BUG

Hi, i have downloaded the lastest version of php sdk


im running my transactions with this values








transaction type ->authorizeOnly();




with the default php sdk, im geting the following errors :




Undefined property: AuthorizeNetCP::$_custom_fields



"return new AuthorizeNetCP_Response($response, $this->_x_post_fields['delim_char'], $this->_x_post_fields['encap_char'], $this->_custom_fields);"


($_custom_fields is defined on partnet class , but its private so its not accecbile from AuthorizeNetCP class)



so i added

private $_custom_fields = array();

to AuthorizeNetCP class


then when im tring again , im getting

Undefined offset: 22

Undefined offset: 23

Undefined offset: 24


(lines 178-181)


so i have changed this lines to be


 $this->split_tender_id      = isset($this->_response_array[22]) ? $this->_response_array[22] : NULL;
                $this->requested_amount     = isset($this->_response_array[23]) ? $this->_response_array[23] : NULL;
                $this->approved_amount      = isset($this->_response_array[24]) ? $this->_response_array[24] : NULL;
                $this->card_balance         = isset($this->_response_array[25]) ? $this->_response_array[25] : NULL;



its seems like i never get this values .

all other values are ok.


after changed api works fine.



is it really the sdk problem ?

I am getting these errors too. It's been a year, isn't this important?

Comparing the new and old AuthorizeNetCP.php files shows that only the

"undefined offset" errors were fixed. The "undefined property" error was NOT fixed.

It doesn't define a class property for _custom_fields (like AuthorizeNetAIM.php does).


I added this code after line 50 and it seems to prevent this php error:


     * Only used if merchant wants to send custom fields.
    private $_custom_fields = array();


Also, the "error_message" property is only defined and returned if there IS an error.

It would be better if it always returned a value (empty string if trx is approved, otherwise an error message string). I fixed my script to only obtain the value of this response property if there was an error, not always.
