PHP mail function doesn't complete sending of e-mail
(31 answers)
Closed 7 years ago.
I'm attempting to make an enquiry form on my site send an email regarding a booking. But I cannot work out my mistake in the PHP, very much a beginner to PHP so don't know where I went wrong.
I receive no email when testing the form on server.
<?php
$firstname = $_post['firstname'];
$lastname = $_post['lastname'];
$bandname = $_post['bandname'];
$email = $_post['email'];
$phoneno = $_post['phoneno'];
$startday = $_post['start_day'];
$startmonth = $_post['start_month'];
$starthour = $_post['start_hour'];
$startminute = $_post['start_minute'];
$endday = $_post['end_day'];
$endmonth = $_post['end_month'];
$endhour = $_post['end_hour'];
$endminute = $_post['end_minute'];
$extras = $_post['extras'];
$to = "some#emailaddress.com";
$subject = "New Message";
mail ($to, $subject, $firstname . $lastname, $bandname, $email, $phoneno, $start_day . $start_month, $start_hour . $start_minute, $end_day . $end_month, $end_hour . $end_minute, $extras);
?>
HTML of my form :
<form action="form.php" class="appnitro" id="form_1062945" method="post" name="form_1062945" style="display: inline-block;">
<div class="form_description medium-8 small-10 columns medium-centered small-centered" style="margin-bottom:45px">
<p>
Please complete the form below to send us details of the booking you would like to make, we will then get back to you within one business day to confirm your booking.

Answer 1

Firstly, all your $_post are incorrect.
That is a superglobal and must read as $_POST.
http://php.net/manual/en/language.variables.superglobals.php
Then you're injecting too many parameters in your mail() function.
Please read the manual:
http://php.net/manual/en/function.mail.php
Your server may not be setup to catch and display/log errors/notices/warnings.
Having used error reporting, would have thrown you many notices.
Add error reporting to the top of your file(s) which will help find errors.
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
// rest of your code
Sidenote: Displaying errors should only be done in staging, and never production.
