使用代码igniter和gmail smtp在localhost上发送来自xampp的电子邮件

Question

I am trying to create and test email functionality in a code igniter app on localhost using xampp server. I am trying to use the Google SMTP mail server by configuring it in php.ini and sendmail.ini. I am getting lots of errors which I cannot understand. My gmail account uses 2 step authentication. does that matter? Here's my code

Controller:

$this->load->library('email');
$from =$this->input->post('email');

$econfig=
    array(
        'protocol'=>'smtp', 
        'smtp_host'=>"smtp.gmail.com",
        'smtp_port'=>465,
        '_smtp_auth'=>TRUE, 
        'smtp_user'=>"deb.pratyush@gmail",
        'smtp_pass'=>"xxxxxxxx",
        'smtp_crypto'=>'ssl',               
        'mailtype'=>'html', 
        'charset'=>'utf-8',
        'validate'=>TRUE);


        $this->email->initialize($econfig);
        $this->email->set_newline("
");
        $msg=$this->input->post('msg');

        $subject = "Contact Request From ".$from ;


        $name=$this->input->post('uname');

        $this->email->to("[e-mail]");
        $this->email->from($from, stripslashes($name));
        $this->email->subject($subject);
        $this->email->message($msg);

        if($this->email->send())
        {
            $this->session->set_flashdata('msg', "Message Sent");
            $url = base_url().'cms/contact-us';
            redirect($url);
        }
        else{

            echo "fail<br>";
            //echo "m=".mail("[e-mail]", $subject, $msg)."<br>";
            echo $this->email->print_debugger();
        }

PHP INI:

SMTP = smtp.gmail.com
smtp_port = 465
sendmail_from = [e-mail]   
sendmail_path = "\"D:\xampp\sendmail\sendmail.exe\" -t"

SENDMAIL INI:

smtp_port=465
smtp_ssl=auto

Answer 1

I found the solution. My gmail account uses 2 step authentication. So i needed to create an app specific password and substitute my earlier password with the app-specific password to gain full access to my gmail account through PHP. I found the link given below in my error log for sendmail.exe

https://support.google.com/accounts/bin/answer.py?answer=185833

It tells you about creating app specific passwords in detail

Code is below:

$econfig=
    array(
        'protocol'=>'smtp', 
        'smtp_host'=>"smtp.gmail.com",
        'smtp_port'=>465,
        '_smtp_auth'=>TRUE, 
        'smtp_user'=>"deb.pratyush@gmail",
        'smtp_pass'=>"<app-specific password>",
        'smtp_crypto'=>'ssl',               
        'mailtype'=>'html', 
        'charset'=>'utf-8',
        'validate'=>TRUE);

SENDMAIL INI:

smtp_server=smtp.gmail.com
smtp_port=465
smtp_ssl=auto

error_logfile=error.log
debug_logfile=debug.log

auth_username=[e-mail]
auth_password=<app-specific password>
force_sender=[e-mail]
