Email message runon sentence

[SFDonovan]

My mail form that send a message to me is one long run-on sentance. How do I format it line by line.

I want

Movement code for my unit:: dogsofwar

My Username:: So and So

My email address:: xxxxxx@xxxxx

Unit I represent:: 3rd ID

Hex my unit is moving to and holding position:: N/A

Hex my unit is moving to and attacking from:: G4

Hex where defending unit is located:: F5

Unit we are attacking:: 716ID 1/726Grenadier

Line by line instead of one long run-on sentance.

Here is part of my code.

if ($op == "sendmovement") {
    if ($sender_email == "") { 
   $email_err = "<center><font class=\"option\"><b><i>"._ENTEREMAIL."</i></b></font></center><br>"; 
   $send = "no"; 
    } 
    if ($send != "no") { 
   $sender_name = removecrlf($sender_name); 
   $sender_email = removecrlf($sender_email); 
   $msg = "$sitename\n\n";
   $msg .= ""._UNITCODE.": $unit_code\n";
   $msg .= ""._SENDERNAME.": $sender_name\n";    

   $msg .= ""._SENDEREMAIL.": $sender_email\n";
   $msg .= ""._ATTACKINGUNIT.": $attackingunit\n";
   $msg .= ""._MOVEHOLDHEX.": $moveholdhex\n";
   $msg .= ""._MOVEATTACKHEX.": $moveattackhex\n";
   $msg .= ""._ATTACKHEX.": $attackhex\n"; 
   $msg .= ""._DEFENDINGUNIT.": $defendingunit\n";       

   $to ="[e-mail]"; 
   $mailheaders = "From: $sender_name <$sender_email>\n"; 
   $mailheaders .= "Reply-To: $sender_email\n\n"; 
   mail($to, $subject, $msg, $mailheaders); 
   echo "<P><B><font color=RED size=6><center>Movement Form has been sent</center></font></p>";

So put the text you want in there and put some line breaks using \n. What are you having trouble with?

[SFDonovan]

I do have line breaks in there don't I? This is what end up in my inbox.

Movement code for my unit:: thunderborne My Username:: Pecore [17th AB] My email address:: [e-mail] Unit I represent:: 17th Airborne Hex my unit is moving to and holding position:: M3 Hex my unit is moving to and attacking from::
Hex where defending unit is located::
Unit we are attacking:: ---

I guess I'll have to assume some of the stuff in there I see are constants you've defined, like _UNITCODE.

The \n should be fine for the message body, although additional headers are supposed to be separated by \r\n rather than just \n. I'd also suggest replacing that last \n\n with \r\n. See what happens when you change that. You might also try viewing the source code of the email and see if the line breaks are actually there. It looks to me like they should be, and I'm guessing they actually are, but your mail client may be displaying it as HTML (for some reason, maybe because of the headers problem).
