codeigniter email subject line removes spaces with “_”

Question

I use codeigniter to send some emails. Everything works fine except subject line. I am creating custom subject line like this

$mailSubject = "Customer Query | " . $bookingID . " | " . $requestID;

and use it like this

$this->email->subject($mailSubject);

But when I receive the email, the subject line looks like

Customer_Query_|_6223871_|_92

Instead I need it like

Customer Query | 6223871 | 92

This is my Function

Answer 1

Please try using below config params

         $config = Array(
         'protocol' => 'smtp',
         'smtp_host' => 'ssl://sub5.mail.xxxxx.com',
         'smtp_port' => 465,
         'smtp_user' => 'account@xxxxx.com',
         'smtp_pass' => 'xxxxx',
         'mailtype' => 'html',
         'charset' => 'iso-8859-1',
         'wordwrap' => TRUE,
         'remove_space' => FALSE
        ); //set the basic configurations

Answer 2

Set your

$config['mailtype'] ='html';

Then

$mailSubject = "Customer Query | ".$bookingID." | ".$requestID;//$nbsp; is space it is replace because your mailtype is html

$this->email->subject($mailSubject);

Replace $this->load->library('email', $config);

With

$this->load->library('email');
$this->email->initialize($config);

I found the reason for the problem. It's only happening in my mail server. For other mail servers it weren't happen. Even in outlook also it is fine. I am really sorry for wasting your valuable time.
