Question

我使用HTML和Ajax从我的网站发送电子邮件，有时会发送该电子邮件，但90％的时间未发送。邮件甚至不在电子邮件的垃圾邮件中。这是我的代码，我在我的网站上已有大约2年的时间，但我从不认为它不起作用，请帮助：

html：

       <form id="contact-form" class="contact-form" action="#">
            <p class="contact-name">
                <input id="contact_name" type="text" placeholder="Full Name" value="" name="name" />
            </p>
            <p class="contact-email">
                <input id="contact_email" type="text" placeholder="Email Address" value="" name="email" />
            </p>
            <p class="contact-message">
                <textarea id="contact_message" placeholder="Your Message" name="message" rows="10" cols="40"></textarea>
            </p>
            <p class="contact-submit">
                <a id="contact-submit" class="submit" href="#">Send Your Email</a>
            </p>

            <div id="response">

            </div>
        </form>

Ajax（fichier main.js）：

$("#contact-submit").on('click',function() {
    $contact_form = $('#contact-form');

    var fields = $contact_form.serialize();

    $.ajax({
        type: "POST",
        url: "http://musamr.com/wp-content/themes/musamr/include/php/contact.php",
        data: fields,
        dataType: 'json',
        success: function(response) {

            if(response.status){
                $('#contact-form input').val('');
                $('#contact-form textarea').val('');
            }

            $('#response').empty().html(response.html);
        }
    });
    return false;
});

contact.php

        $this->email = trim($details['email']);

        }

            $this->response_status = 0;

        // Check email
        if(!$this->email)
        {

            $this->response_status = 0;
        }
    }

    private function sendEmail(){
        $mail = mail($this->email_admin, $this->subject, $this->message,
             "From: ".$this->name." <".$this->email.">\r\n"
            ."Reply-To: ".$this->email."\r\n"
        ."X-Mailer: PHP/" . phpversion());

        if($mail)
        {
            $this->response_status = 1;
            $this->response_html = '<p>Thank You!</p>';
        }
    }

    function sendRequest(){
        $this->validateFields();
        if($this->response_status)
        {
            $this->sendEmail();
        }

        $response = array();
        $response['status'] = $this->response_status;   
        $response['html'] = $this->response_html;

        echo json_encode($response);
    }
}

$contact_form = new Contact_Form($_POST, $admin_email, $message_min_length);
$contact_form->sendRequest();

?>

邮件功能极其不可靠。您应该考虑使用SMTP服务器和类似PHPMAILER的库来简化集成。

phpmailer：https://github.com/PHPMailer/PHPMailer

邮件功能将尝试发送邮件，但是多次发送到用户的垃圾邮件文件夹中，否则目的地可能会拒绝它。

也可以使用该正则表达式代替该正则表达式 $db

PHP和Ajax表单发送电子邮件，但电子邮件未发送
