使用codeigniter和ajax发送电子邮件，电子邮件已发送但出现错误消息

Question

我已经由其他人编写了此代码，问题是在发送电子邮件时始终显示“错误发送！”。 即使在大多数情况下，电子邮件发送成功也是如此。

查看（表单提交）：

                        <!-- Contact Form Starts -->
                        <div class="col s12 m7 l9 xl9 rightside">

控制器（发送功能）：

    function send()
{

    $this->load->library('email');

    $config['mailtype'] = 'html';
    $config['charset'] = 'utf-8';
    $config['wordwrap'] = TRUE;

    $this->email->initialize($config);

    $body    = '
        <strong>Name: </strong>'.$this->input->post("name").'<br />
        <strong>Email: </strong>'.$this->input->post("email").'<br />
        <strong>Message: </strong>'.$this->input->post("message").'<br />
    ';

    $emailto = 'anemail@email.com'; //any email

    $this->load->library('email');

    $this->email->from($this->input->post("email"), $this->input->post("name"));
    $this->email->to($emailto);

    $this->email->subject('New Request');
    $this->email->message($body);

    $this->email->send();


    $data['contactus'] = $this->Emodel->contactus('en');
    $data['pages'] = $this->Emodel->get_pages('en');
    $data['social'] = $this->Emodel->get_header_social();
    $data['result'] = "Message Sent Successfully";


    $data['_title'] = "Contact";

    $this->load->view('en/home',$data);
}

JS档案：

(function($) {

"use strict";

$(document).ready(function() {

    // PRELOADER
    $("body").toggleClass("loaded");
    setTimeout(function() {
        $("body").addClass("loaded");
    }, 3000);

    // PORTFOLIO DIRECTION AWARE HOVER EFFECT
    var item = $("#bl-work-items>div");
    var elementsLength = item.length;
    for (var i = 0; i < elementsLength; i++) {
        $(item[i]).hoverdir();
    }

    // TEXT ROTATOR

})(jQuery);

我对ajax和jquery不太了解，所以我复制了整个代码

由于您的控制器未将成功数据传递给视图，因此请使用此代码。

function send()
{
    $this->load->library('email');
    $config['mailtype'] = 'html';
    $config['charset'] = 'utf-8';
    $config['wordwrap'] = TRUE;

    $this->email->initialize($config);

    $body    = '
        <strong>Name: </strong>'.$this->input->post("name").'<br />
        <strong>Email: </strong>'.$this->input->post("email").'<br />
        <strong>Message: </strong>'.$this->input->post("message").'<br />
    ';

    $emailto = 'anemail@email.com'; //any email
    $this->load->library('email');
    $this->email->from($this->input->post("email"), $this->input->post("name"));
    $this->email->to($emailto);
    $this->email->subject('New Request');
    $this->email->message($body);
    if ($this->email->send()) {
       echo 'success';
    } else {
       echo 'error';
    }
}
