Email Library Issues

I have the code 
$this->load->library('email');
which loads the library properly, or i thought...
however when i try
$this->email->from(EMAIL_FROM);
i get this
Fatal error: Call to a member function from() on a non-object in /var/screenu-www/screenu-web/screenu/application/models/customers_model.php on line 147

You might try swapping out your /system/ directory for a fresh copy. Besides that, you might try turning on debug logging and see if there are any hints.

Dude, seriously? One guy has his system/ dir messed up and now everybody has to be advised to check that by default?

Well here is the thing so I have two types of creating new user that calls on the email library. One type works perfectly and the other doesn't work. And the code is basically the same.... It is also within the same controller file.

Unless you show us some code, we really have no chance of helping you.

Issue is with the add_demo function.

maybe your function initialize() replace $this->email (CI library object which u loaded) with NULL value ... then u already dont have email library object .. and u using from funcion on variable $this->email which u defined as NULL

Do a little debugging:

PHP Code:

// Send out confirmation email
if( ! $this->load->is_loaded('Email') )
    $this->load->library('email');

if( ! $this->load->is_loaded('Email') )
    exit('No email library loaded. WTF???');

if( ! defined('EMAIL_FROM') )
    exit('No EMAIL_FROM available');

if( ! defined('SITE_NAME') )
    exit('No SITE_NAME available');

$message = $this->load->view('public/email/demo', $user_data, TRUE);

var_dump( $message ); // Or use some other way to check the message

$this->email->from(EMAIL_FROM);
$this->email->to($data['email']);
$this->email->subject('Demo Account Created at ' . SITE_NAME);
$this->email->message($message);
$this->email->send(); 


Also, what is your email config? Only default?

As i suspected the email library just isn't loading. Below is snippet of email.php

PHP Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

$config['protocol'] = 'mail';
$config['mailpath'] = '/usr/sbin/sendmail -t -i';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = FALSE;
$config['mailtype'] = 'html';
$config['smtp_host'] = 'smtp.gmail.com';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = '***********************';
$config['smtp_port'] = '465';
