Question

I have a library in CodeIgniter called “someclass”.

class someclass extends CI_Controller {

    function __construct() {
        parent::__construct();
        $this->load->helper('url');
        $this->load->helper('form');
        $this->load->library('email');
        $this->load->database();

       // $this->load-> library('database');

    }
    function email($naar=0,$onderwerp=0,$bericht=0){
        if ($naar > 0 && $naar<10) {

            $to = "[e-mail]"
            //this is the part where it goes wrong            

            $CI =& get_instance();
            $this->load->library('email');               
            //some one said that i needed ti assign the library's
            $this->_assign_libraries();

            $this->email->from('[e-mail]', 'test');
            $this->email->to($to);
            $this->email->subject($onderwerp);
            $this->email->message("Test

                bericht :
                ".$bericht);

            $this->email->send();
            // echo $this->email-> print_debugger();
        }
    }
}

I get the following error:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: someclass::$email

Filename: libraries/someclass.php

Line Number: 139

You can have 2 situations in my vision.

1. First you can use a helper. Create a .php file (ex: general_helper.php) which can be autoloaded or loaded where you will use it. Autoload if from config/autoload.php with ‘general’ name.

Here, you can create a method called sendEmail

function sendEmail($naar=0,$onderwerp=0,$bericht=0)
{
    $CI =& get_instance();

        $CI->load->library('email');               
        //or autoload it from /application/config/autoload.php

        $CI->email->from('[e-mail]', 'test');
        $CI->email->to($to);
        $CI->email->subject($onderwerp);
        $CI->email->message("Test

            bericht :
            ".$bericht);

        $CI->email->send();

}

Load your custom library in your controller and call id with sendEmail(....)

1. You can extend native email library class and create a method inside that class called sendEmail for example:

   class MY_Email extends CI_Email {
   public function _construct()
   {
   parent::_construct();
   }
   public function sendEmail () ….. etc.
   }

From your controller load native library class, use $this->load->library('email') and send your email by calling $this->email->sendEmail(...)
