sendmail - PHP Mail Sending Blank Message On Page-Load -

i having issue php mailer. sending blank email every time page loaded.

i'm sure it's simple (maybe missing condition if submit button hit) fix this.

their documentation doesn't seem have 1 though , script first worked when first used started sending emails on page load after first few times. thanks!

<form method="post" action="">     <div class="form-group">         <input name="name" type="text" class="form-control" placeholder="enter name">     </div>     <div class="form-group">         <input name="email" type="email" class="form-control" placeholder="enter email">     </div>     <div class="form-group">         <input name="subject" type="text" class="form-control" placeholder="enter subject">     </div>     <div class="form-group">          <textarea name="message" class="form-control" rows="5" placeholder="enter message"></textarea>     </div>     <button name="submit" type="submit" value="submit" class="btn btn-submit">submit</button> </form>  <?php   require '/phpmailer/phpmailerautoload.php'; require_once('/phpmailer/class.phpmailer.php'); include("/phpmailer/class.smtp.php");  $emailaddress = 'info@newpointdigital.com';  $message=     'name:  '.$_post['name'].'<br />     email:  '.$_post['email'].'<br />     subject:    '.$_post['subject'].'<br />     ip: '.$_server['remote_addr'].'<br /><br />     message:<br /><br />     '.nl2br($_post['message']).'     ';  $mail             = new phpmailer(); $mail->issmtp(); // telling class use smtp $mail->host       = "smtp.gmail.com"; // smtp server //$mail->smtpdebug  = 2;                     // 1 = errors , messages,2 = messages $mail->smtpauth   = true;                  // enable smtp authentication $mail->host       = "smtp.gmail.com"; // sets smtp server $mail->port       = 465;                    // set smtp port gmail server $mail->username   = "info@newpointdigital.com"; // smtp account username (the email account created) $mail->password   = "newpoint!@#$";        // smtp account password (the password above email account) $mail->smtpsecure = 'ssl';                            // enable encryption, 'ssl' accepted  $mail->charset  = 'utf-8';  // interprets foreign characters $mail->setfrom($_post['email']); $mail->addreplyto($_post['email']); $mail->subject    = "contact form ".$_post['name']." "; $mail->msghtml($message);  $mail->addaddress($emailaddress);  if(!$mail->send()) {     echo 'message not sent.';     echo 'mailer error: ' . $mail->errorinfo; } else {     echo 'message has been sent'; }        ?> 

you don't check see if form submission occurred. call email code when page loads. there several ways decide if form submission occurred. 1 way check see if form action post:

if ($_server['request_method'] === 'post') {     // email code goes here } 

you can check see if submit button pressed:

 if (isset($_post['submit'])) {       // email code goes here  } 

other things know:

• you don't data validation still possible submit nothing resulting in blank email being sent
• you don't protect against header injections makes form vulnerable sending spam
