Hello KK,

from the screenshot is seems you are trying to load CI resources from outside the application folder. Is Contact.php a CI controller? Can you share it? Remember to remove address and password as the post is public.

[KagaKuro]

yes. I did put the contact.php in the root file.

but I've change it and put it in the controller

<?php
class Contactform extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper(array('form','url'));
        $this->load->library(array('session', 'form_validation', 'email'));
    }

    function index()
    {
        //set validation rules
        $this->form_validation->set_rules('name', 'Name', 'trim|required|xss_clean|callback_alpha_space_only');
        $this->form_validation->set_rules('email', 'Emaid ID', 'trim|required|valid_email');
        $this->form_validation->set_rules('subject', 'Subject', 'trim|required|xss_clean');
        $this->form_validation->set_rules('message', 'Message', 'trim|required|xss_clean');

        //run validation on form input
        if ($this->form_validation->run() == FALSE)
        {
            //validation fails
            $this->load->view('contact_form_view');
        }
        else
        {
            //get the form data
            $name = $this->input->post('name');
            $from_email = $this->input->post('email');
            $subject = $this->input->post('subject');
            $message = $this->input->post('message');

            //set to_email id to which you want to receive mails
            $to_email = '[e-mail]';

            //configure email settings
            $config['protocol'] = 'smtp';
            $config['smtp_host'] = 'ssl://smtp.gmail.com';
            $config['smtp_port'] = '465';
            $config['smtp_user'] = '[e-mail]';
            $config['smtp_pass'] = 'password';
            $config['mailtype'] = 'html';
            $config['charset'] = 'iso-8859-1';
            $config['wordwrap'] = TRUE;
            $config['newline'] = "\r\n"; //use double quotes
            //$this->load->library('email', $config);
            $this->email->initialize($config);                        

            //send mail
            $this->email->from($from_email, $name);
            $this->email->to($to_email);
            $this->email->subject($subject);
            $this->email->message($message);
            if ($this->email->send())
            {
                // mail sent
                $this->session->set_flashdata('msg','<div class="alert alert-success text-center">Your mail has been sent successfully!</div>');
                redirect('contactform/index');
            }
            else
            {
                //error
                $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">There is error in sending mail! Please try again later</div>');
                redirect('contactform/index');
            }
        }
    }

    //custom validation function to accept only alphabets and space input
    function alpha_space_only($str)
    {
        if (!preg_match("/^[a-zA-Z ]+$/",$str))
        {
            $this->form_validation->set_message('alpha_space_only', 'The %s field must contain only alphabets and space');
            return FALSE;
        }
        else
        {
            return TRUE;
        }
    }
}
?>

But another error happen. did i have to setup anything before I can make the code works?

[cereal]

Okay,

consider to use the identical operator === on line 20:

if ($this->form_validation->run() == FALSE)

The alpha_space_only() callback can fail when using accented characters like àèéìòùñ, so you may want to replace the regex pattern to:

preg_match('/^[\p{L} ]+$/ui', $str)

a part this your code seems fine.

But another error happen.

So, what is the error?

[KagaKuro]

This post has no text-based content.

[cereal]

It, probably, happens because you are calling the session inside application/core/MY_Loader.php but you are loading it from the controller, which is executed after the MY_Loader. Have you tried to autoload the session?

[KagaKuro]

no. i did not try. how can i do it?

[cereal]

Open application/config/autoload.php and set session inside:

$autoload['libraries'] = array('session');

You can do the same with other libraries or helpers that you will use constantly, like database or form.

More info: https://codeigniter.com/user_guide/general/autoloader.html

[KagaKuro]

I've add it and it give me error at my fast-store-list page ( a page that I used iFrame )

This error appear above my webpage.

Can I just give up . haaaaaaaaaaaa

[cereal]

Hehe, sure you can!

If you want to solve it, instead, read the notice, it says Use of undefined constant session - assumed 'session', which means you probably wrote:

$autoload['libraries'] = array(session); # without quotes

Instead of:

$autoload['libraries'] = array('session'); # with quotes

By adding quotes the value is considered a string, which is what you need in this case.
