echo $strBody;
$to= $_SESSION['email'];
$from = "**********";
$subject = "Testing mail";
$message = "Hello! This is a simple email message.";
echo mail($to,$subject,$strBody,$from);

if i use $strBody i get error...if i use $message the code works fine. I have display $strBody and it shows up fine but when i try to use it in mail() i am getting error.

Can anyone please help.

According to the PHP Manual for mail(), the lines in the message must be 70 chars long max. and should be separated with \n (LF). While I've never encountered a problem caused by this, you can give it a try.

Oh, I generally write down message HTML in a single string like:

$message = '
    <div>
        <span>...
        ...etc...
        ';

So it's getting newlines automatically. You can simply trim $strBody=$strBody." parts and concatenate the message into a single multiline string.

If you can't get it working, you can try ready-made classes like Zend Mail.

$to= $_SESSION['email']; Are you sure that your session contains correct e-mail address? Try to debug it. Maybe you forgot session_start before any output?
