PHP Redirect

[diggfann2]

I have written a small script using HTML input variables and the php redirect command, however I am a amateur programmer @ PHP. Is there any point of reference i can get appointed 2? Possibly someone willing to fix my code for a small fee @ PayPal?

The code is as follows:

<title>txt Drop</title><style>body{
	background-color:#FFFFFF; 
	background-image: url('images/back.jpg');
	background-repeat: repeat-x;
	background-position: bottom;
	background-attachment: fixed;
	font-family: Tahoma, sans-serif;
	font-size: 11px;
	color: #636363;
}

#navtop {
	background-image: url(images/nav.jpg); 
	background-repeat: no-repeat; 
	border-top: 1px solid #C0C0C0;
	border-right: 1px solid #C0C0C0;
	border-bottom: 1px solid #C0C0C0;
	height: 17px;
}

.nav {
	background-color: #E4EAEA;
	padding: 2px 2px 2px 2px;
	height: 12px;
}

.bottom {
	background-image: url(images/nav.jpg); 
	background-repeat: no-repeat; 
	border-top: 1px solid #C0C0C0;
	border-right: 1px solid #C0C0C0;
	border-left: 1px solid #C0C0C0;
	height: 17px;
}

.bottom2 {
	background-color: #E4EAEA;
	font-family: Tahoma, sans-serif;
	font-size: 11px;
	font-weight: bold;
	color: #636363;
	height: 100px;
	padding: 3px 3px 3px 3px; 
	border: 1px solid #C0C0C0;
}

.floatl {
	background-color: #D1DEDE;
	padding: 2px 2px 2px 2px;
	height: 11px;
	text-align: center;
}

#content {
	background-color: #E4EAEA;
	font-family: Tahoma, sans-serif;
	font-size: 11px;
	color: #636363;
	padding: 1px 1px 1px 5px;
	height: 300;
	border-left: 1px solid #C0C0C0;
	border-right: 1px solid #C0C0C0;
	border-bottom: 1px solid #C0C0C0;
}

#contact{
	background-image: url(images/nav.jpg); 
	background-repeat: no-repeat; 
	border-top: 1px solid #C0C0C0;
	border-right: 1px solid #C0C0C0;
	height: 17px;
}

.cfloat{
	padding: 2px 2px 2px 2px;
	height: 11px;
	text-align: center;
	border-bottom: 1px solid #C0C0C0;
	border-left: 1px solid #C0C0C0;
}

#rss{
	width: 550px;
}

a:link {
	font-family: Tahoma, sans-serif;
	font-size: 11px;
	font-weight: bold;
	color: #636363;
	text-decoration: none;
}

	text-decoration: none;
}

a:active {

	font-size: 11px;

	color: #636363;
	text-decoration: none;
}

a:hover {
	font-family: Tahoma, sans-serif;

}

.vbcode

	background-color:#E9E9E9;
	padding:3px;
	margin: 5px;
	border: 1px solid #999999;
	display: block;
}

.r1 { background-color: #EFF3F3; }
.r2 { background-color: #D8E2E2; }</style>
<meta name = "viewport" content="width=device-width,height=device-height" /> 

<?php if(isset($_POST['submit'])){
header('redirect:'.$_POST['service'].$_POST['num']');
}
else{
echo "
<form method=\"POST\" ENCTYPE=\"multipart/form-data\">
<table>
<tr><td>Tracking Number:</td><td><input type=\"text\" name=\"num\"><br></td></tr>
<tr><td>Service:</td><td><select name=\"ser\">
<option value=\"https://fedex.com/mobi/track.do?shipDate=trackingNbr=\">FedEx</option>
<option value=\"http://mobile.ups.com/ups/-1-3-2;jsessionid=732769EA6CA319415A3400B481B947CB.srv2?a=2.1039004&wi3.1039004.-9999=1Z6874R09023233800\">UPS</option>
</select></td></tr>
<tr><td>Tracking Number:</td><td><input type=\"text\" name=\"amo\"><br></td></tr>
<tr><td></td><td><input type=submit name=submit value=\"Start\"><br><br></td></tr>
<SCRIPT LANGUAGE=\"JavaScript\" TYPE=\"text/javascript\">
document.forms[0].num.select()</SCRIPT>
";
}
?>
  </div>

When run, I receive this error:

Warning: Cannot modify header information - headers already sent by (output started at /home/tjoozeyc/public_html/txtdrop/index.php:135) in /home/tjoozeyc/public_html/txtdrop/index.php on line 135

That's only part of the script, what with the missing doctype definition, head, body tags etc.... and the lone </div> at the end?

Well the solution to the secret: Nothing may be sent to the browser before that "header" line.

Simplest way to make the code work: put that part in front of everything:

<?php 
if (isset($_POST['submit'])) { 
    header('redirect:'.$_POST['service'].$_POST['num']');
    exit;
}
?>

and the rest of your code below
