POST Request coming up blank, why? - php

Question

I have the following code saved as send.php:
<?php
$to_email = "person#gmail.com";
$subject = $_POST['subject'];
$body = "Hi, This is test email send by PHP Script";
$headers = "From: Me#myWebsite.com";
if ( mail($to_email, $subject, $body, $headers)) {
echo("Email successfully sent to $to_email...");
} else {
echo("Email sending failed...");
}
?>
The email sends if I navigate to https://myWebsite.com/Stuff/send.php
and make $subject = "something"
But if I set $subject to be a POST variable. It does not send the subject when I write this URL in the browser (as in, the email still sends but the subject is now blank):
https://myWebsite.com/Stuff/send.php?subject=notworking

Answer 1

To get both $_POST and $_GET you can use $_REQUEST which will work for both.
In your code replace
$subject = $_GET['subject'];
With
$subject = $_REQUEST['subject'];
If someone direct hit the URL in browser without paramter subject you can prevent them using
if(!empty($_REQUEST['subject']))
{
$to_email = "person#gmail.com";
$subject = $_REQUEST['subject'];
$body = "Hi, This is test email send by PHP Script";
$headers = "From: Me#myWebsite.com";
if ( mail($to_email, $subject, $body, $headers))
echo("Email successfully sent to $to_email...");
else
echo("Email sending failed...");
}

If you want to extract the values from the URL parameters then you need to use the $_GET
global variable to get the data like this,
<?php
$to_email = "person#gmail.com";
$subject = $_GET['subject'];
$body = "Hi, This is test email send by PHP Script";
$headers = "From: Me#myWebsite.com";
if ( mail($to_email, $subject, $body, $headers)) {
echo("Email successfully sent to $to_email...");
} else {
echo("Email sending failed...");
}
?>

Try it.
<?php
$to_email = "person#gmail.com";
$subject = (isset($_GET['subject']) && (!empty($_GET['subject']))?$_GET['subject']:"No Subject";
$body = "Hi, This is test email send by PHP Script";
$headers = "From: Me#myWebsite.com";
if ( mail($to_email, $subject, $body, $headers))
echo("Email successfully sent to $to_email...");
else
echo("Email sending failed...");
?>
