使用SMTP PHP phpmailer发送邮件

Question

I want to be able to send a mail to my Email address whenever I fill in and submit my contact form. I followed a tutorial on how to do that but unfortunately it does not send a mail to mailbox. Everytime I submit the form it justs returns the error message 'There is an error' Can someone please check this code to find out what can be the problem?

Here is the php code

        <?php
            //index.php

            $error = '';
            $name = '';
            $email = '';
            $subject = '';
            $message = '';

            function clean_text($string)
            {
            $string = trim($string);
            $string = stripslashes($string);
            $string = htmlspecialchars($string);
            return $string;
            }

            if(isset($_POST["submit"]))
            {
            if(empty($_POST["name"]))
            {
                $error .= '<p><label class="text-danger">Please Enter your Name</label></p>';
            }
            else
            {
                $name = clean_text($_POST["name"]);
                if(!preg_match("/^[a-zA-Z ]*$/",$name))
                {
                    $error .= '<p><label class="text-danger">Only letters and white space allowed</label></p>';
                }
            }
            if(empty($_POST["email"]))
            {
                $error .= '<p><label class="text-danger">Please Enter your Email</label></p>';
            }
            else
            {
                $email = clean_text($_POST["email"]);
                if(!filter_var($email, FILTER_VALIDATE_EMAIL))
                {
                    $error .= '<p><label class="text-danger">Invalid email format</label></p>';
                }
            }
            if(empty($_POST["subject"]))
            {
                $error .= '<p><label class="text-danger">Subject is required</label></p>';
            }
            else
            {
                $subject = clean_text($_POST["subject"]);
            }
            if(empty($_POST["message"]))
            {
                $error .= '<p><label class="text-danger">Message is required</label></p>';
            }
            else
            {
                $message = clean_text($_POST["message"]);
            }
            if($error == '')
            {

                $mail = new PHPMailer;

                $mail->WordWrap = 50;                           //Sets word wrapping on the body of the message to a given number of characters
                $mail->IsHTML(true);                            //Sets message type to HTML             
                $mail->Subject = $_POST["subject"];             //Sets the Subject of the message

                if($mail->Send())                               //Send an Email. Return true on success or false on error
                {

Answer 1

Please change this line.

$mail = new PHPMailer;

To:

$mail = new PHPMailer(true);

Put code in try and catch block as:

try {

 require 'class/class.phpmailer.php';
            $mail = new PHPMailer;
            $mail->IsSMTP();                                //Sets Mailer to send message using SMTP
            $mail->Host = 'kwchems.com';        //Sets the SMTP hosts of your Email hosting, this for Godaddy
            $mail->Port = '465';                                //Sets the default SMTP server port
            $mail->SMTPAuth = true;                         //Sets SMTP authentication. Utilizes the Username and Password variables
            $mail->Username = 'info@kwchems.com';                   //Sets SMTP username
            $mail->Password = 'txpxbaron45';                    //Sets SMTP password
            $mail->SMTPSecure = 'tls';                          //Sets connection prefix. Options are "", "ssl" or "tls"
            $mail->From = $_POST["email"];                  //Sets the From email address for the message
            $mail->FromName = $_POST["name"];               //Sets the From name of the message
            $mail->AddAddress('info@kwchems.com', 'Name');      //Adds a "To" address
            $mail->AddCC($_POST["email"], $_POST["name"]);  //Adds a "Cc" address
            $mail->WordWrap = 50;                           //Sets word wrapping on the body of the message to a given number of characters
            $mail->IsHTML(true);                            //Sets message type to HTML             
            $mail->Subject = $_POST["subject"];             //Sets the Subject of the message
            $mail->Body = $_POST["message"];                //An HTML or plain text message body
            if($mail->Send())                               //Send an Email. Return true on success or false on error
            {
                $error = '<label class="text-success">Thank you for contacting us</label>';
            }
            else
            {
                $error = '<label class="text-danger">There is an Error</label>';
            }
            $name = '';
            $email = '';
            $subject = '';
            $message = '';

} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}

The true param means it will throw exceptions on errors, which we need to catch.
