Php 联系人表单发送错误

我正在使用一个模板，只是想让我的联系表正常工作（试着看看它是如何工作的，发送消息等等）。填写我的联系人表单，然后点击“提交”时，会弹出一个错误，而不是成功完成：

由于出现意外错误，无法发送电子邮件。请稍后再试

原因: 无法实例化邮件函数

这是我的HTML联系人表单：

<div class="col_half col_last">

    <div class="fancy-title title-dotted-border test-john">
        <h3>Send us an Email</h3>
    </div>

    <div class="contact-widget">

        <div class="contact-form-result"></div>

        <form class="nobottommargin" id="template-contactform" name="template-contactform" action="include/sendemail.php" method="post">

        <div class="form-process"></div>

        <div class="col_one_third">
            <label for="template-contactform-name">Name <small>*</small></label>
            <input type="text" id="template-contactform-name" name="template-contactform-name" value="" class="sm-form-control required" />
        </div>

        <div class="col_one_third">
            <label for="template-contactform-email">Email <small>*</small></label>
            <input type="email" id="template-contactform-email" name="template-contactform-email" value="" class="required email sm-form-control" />
        </div>

        <div class="col_one_third col_last">
            <label for="template-contactform-phone">Phone</label>
            <input type="text" id="template-contactform-phone" name="template-contactform-phone" value="" class="sm-form-control" />
        </div>

        <div class="clear"></div>

        <div class="col_full">
            <label for="template-contactform-subject">Subject <small>*</small></label>
            <input type="text" id="template-contactform-subject" name="template-contactform-subject" value="" class="required sm-form-control" />
        </div>

        <div class="clear"></div>

        <div class="col_full">
            <label for="template-contactform-message">Message <small>*</small></label>
            <textarea class="required sm-form-control" id="template-contactform-message" name="template-contactform-message" rows="6" cols="30"></textarea>
        </div>

        <div class="col_full hidden">
            <input type="text" id="template-contactform-botcheck" name="template-contactform-botcheck" value="" class="sm-form-control" />
        </div>

        <div class="col_full">
            <button name="submit" type="submit" id="submit-button" tabindex="5" value="Submit" class="button button-3d nomargin">Submit Comment</button>
        </div>

        </form>
    </div>

</div>

这给了我更多的问题。

mail.yourdomain.com

中的

邮件是什么？是cPanel、我的电子邮件的用户/通行证吗？
以下是我在Bluehost上的设置方式：

function mailerExpressBlueHost(array $mailInputs){

         require_once '../includes/phpmailer/PHPMailerAutoload.php';

         $mail = new PHPMailer();
         $mail->IsMail();

         $mail->SetFrom('skipper@yourdomain.com'); // make sure this is an andress 
                                                 // on your domain        
         $mail->IsHTML(true);
         $mail->addAddress($mailInputs['addAddress']);    
         $body = $mailInputs['body'] ;              
         $mail->isHTML(true);
         $mail->Subject = $mailInputs['subject'] ;
         $mail->Body    = $body;

         if(!$mail->send()) {
            return 'Message could not be sent.' . 'Mailer Error: ' . $mail->ErrorInfo;  
         } else {
            return 'Message has been sent';
         }

          $mail->ClearAddresses();
}

您是在本地服务器上尝试此操作吗？我认为您需要在PHPMail$mail实例上设置其他属性，除非出于安全考虑而忽略这些属性。@DCR No（在我的实时托管站点| | Magnus Eriksson上）-这是否意味着我需要将表单中的值更改为“POST”而不是“SUBMIT”？|兰登：我没有成功，所以不完全确定那意味着什么，我说错了，看错了线。删除了我的评论。可能，我会建议你无论如何不要使用
mail（）
，所以无论如何都值得一试。
