View Full Version : Mail Problems

08-28-2009, 08:45 PM
Hi Guys,

I have a problems trying to configure a mail script. I have a form with four fields: name="email", name="First", name="Datefrom". name="Dateto".

The mail sending script is as follows:

$email = $_POST["email"];

$myname = "Lewis Villa Menorca";
$mymail = "";

$subject = "Reservation Confirmation";
$body = "Dear $_POST["First"]. This is to confirm your reservation
at the Lewis Villa in Menorca for the following dates:

Notice how I can continue typing right on the next line!";

$headers = "Content-Type: text/plain; charset=us-ascii\nFrom: $myname <$mymail>\nReply-To: <$mymail>\nReturn-Path: <$mymail>\nX-Mailer: PHP";

if ($email != "") { mail($email,$subject,$body,$headers); }


Within the code I have included in the $body the $Post_First. This produces an error.

My question is: How do I insert code to use the First, Datefrom and Dateto fields from the form?

While you can do this:

$var = "something $anotherVar something else";

You cannot do this

$var = "something $_POST['var'] something else";

In the case of using something like $_GET or $_POST, or even multi-dimensional arrays, try surrounding the variable in curly braces { } or concatenating the strings together, like so:

$var = "something {$_POST['var']} something else";
$var = "something " . $_POST['var'] . " something else";

Hi bacterozoid,

Thanks for your response.

Are you saying that I could do some thing like:

$body = $var = "Dear {$_POST['First']}
$var = "something {$_POST['Datefrom']}

To clean up what I think you mean, you could do this:

$body = "Dear {$_POST['First']}, thank you for contacting us. This message was sent on {$_POST['Datefrom']}";

Your last response worked just great. Just what I wanted.

Are you checking the form inputs before using them? If you aren't, you are opening yourself up to an email injection attack.

Hi oracleguy,

Thanks for the warning. This form will be used only by the Administrator and is behind a protected area.

However, because my user level is low I would appreciate an explanation how I could prevent an email injection attack.

this is the code i normally use to validate against
injection attacks

function IsInjected($str)
$injections = array('(\n+)',
$inject = join('|', $injections);
$inject = "/$inject/i";
return true;
return false;
