To send an email using Gmail SMTP in CodeIgniter, you can use the following code:

First, make sure you have configured CodeIgniter to use an email library such as SMTP. You can do this by updating the 'config' file located at application/config/config.php with your Gmail SMTP details:

$config['protocol'] = 'smtp'; $config['smtp_host'] = 'ssl://smtp.gmail.com'; $config['smtp_port'] = '465'; $config['smtp_user'] = 'your_email@gmail.com'; $config['smtp_pass'] = 'your_password';

Next, create a controller method where you will send the email:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

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

    $this->email->from('your_email@gmail.com', 'Your Name');
    $this->email->to('recipient_email@example.com'); 
    $this->email->subject('Email Test');
    $this->email->message('Testing the email class.');

    if($this->email->send()) {
        echo 'Email sent';
    } else {
        show_error($this->email->print_debugger());
    }
}

Don't forget to replace 'your_email@gmail.com' and 'your_password' with your actual Gmail email address and password. Also, update 'recipient_email@example.com' with the email address of the recipient.

Now, you can call the 'send_email' method from your browser or any other HTTP client to send an email using Gmail SMTP in CodeIgniter.
