CI_Email::send()

send([$auto_clear = TRUE])

The e-mail sending method. Returns boolean TRUE or FALSE based on success or failure, enabling it to be used conditionally:

if ( ! $this->email->send())
{
        // Generate error
}

This method will automatically clear all parameters if the request was successful. To stop this behaviour pass FALSE:

if ($this->email->send(FALSE))
{
        // Parameters won't be cleared
}
