将表单数据发送给电子邮件编码器 - Sending form data to an email codeigniter

Sending form data to an email codeigniter

我正试图将表单数据发送到电子邮件。功能运行正常，但电子邮件没有发送到指定的电子邮件地址。我收到的回复是100，但是没有收到电子邮件。

我的控制器:

<?php
class Contact extends CI_Controller {
public function sendemail()
    {
        $this->load->model('Contactmodel');
        $response=array();
        $response=$this->Contactmodel->sendemail();
        echo json_encode($response);
    }
}
?>

我的模型

<?php
class Contactmodel extends CI_Model
{       
    public function _construct()
    {
        parent::_construct();
    }
    public function sendemail()
    {           
        $name = $_REQUEST['name'];
        $email = $_REQUEST['email'];
        $subject = $_REQUEST['subject'];
        $message = $_REQUEST['message'];
        $returnarray = array();
        $to_email = 'cse.akhilraj@gmail.com';
        $this->email->to($to_email);
        $this->email->from($email, $name);
        $this->email->subject($subject);
        $this->email->message($message);
        if($this->email->send())
        {
            $returnarray[0] = 100;
        }
        else
        {
            $returnarray[0] = 101;
        }
        return $returnarray;
    }
}
?>

    <?php

                    return str_replace($bad,"",$string);
                }
                $email_message .= "First Name: ".clean_string($name)."'n";
                $email_message .= "Email: ".clean_string($email)."'n";

                    'X-Mailer: PHP/' . phpversion();
                $this->email->to($email_to);

        if($this->email->send())
        {
            $returnarray[0] = 100;
        }
