Do_mail function in codeignter

The do_mail function in CodeIgniter!

In CodeIgniter, the do_mail function is a part of the Email library, which is a built-in library that allows you to send emails from your application. The do_mail function is the main function that sends the email.

Here's a breakdown of what the do_mail function does:

Validation: The function first validates the email settings and the email message. It checks if the email settings are properly configured, and if the email message has a valid subject, message, and recipient(s).
Email preparation: If the validation is successful, the function prepares the email message by setting the headers, body, and attachments (if any).
SMTP connection: The function establishes a connection to the SMTP server using the email settings (e.g., host, port, username, password).
Email sending: The function sends the email using the SMTP connection. It uses the mail() function to send the email, which is a PHP function that sends an email using the SMTP protocol.
Error handling: If there's an error during the email sending process, the function catches the error and returns an error message.

To use the do_mail function in your CodeIgniter application, you need to:

Load the Email library in your controller: $this->load->library('email');
Set the email settings: $this->email->set_newline("\r\n"); (optional)
Set the email message: $this->email->from('[email protected]', 'Your Name'); (optional)
Set the recipient(s): $this->email->to('[email protected]'); (optional)
Set the subject and message: $this->email->subject('Your Subject'); and $this->email->message('Your Message'); (optional)
Call the do_mail function: $this->email->do_mail();

Here's an example:

<?php

class MyController extends CI_Controller {

    public function send_email() {
        $this->load->library('email');

        $this->email->from('[email protected]', 'Your Name');
        $this->email->to('[email protected]');
        $this->email->subject('Your Subject');
        $this->email->message('Your Message');

        $this->email->do_mail();
    }

}

Note that you need to configure your email settings in the config/email.php file before using the do_mail function.
