Header Problem

[elmas156]

I've got this sign in code:

 

[code=php:0]
<?php
include("conf.inc.php"); // Includes the db and form info.
if ($_SESSION['logged'] == 1) { // User is already logged in.
    $_SESSION['email'] = $email;
header("Location: main.php"); // Goes to main page.
exit(); // Stops the rest of the script.
} else {
if (!isset($_POST['submit'])) { // If the form HAS NOT been submitted.
	echo "<td width=\"320\" height=\"50\" align=\"left\" valign=\"middle\"> </td>";
      	echo "<td width=\"360\" height=\"50\" align=\"left\" valign=\"middle\">";
	echo "<form name=\"form\" action=\"index.php\" method=\"POST\" style=\"margin-bottom:0;\">";
	echo "<a href=\"signup.php\" class=\"bluelink\">Sign Me Up!</a>                  ";
	echo "<a href=\"pwordhelp.php\" class=\"bluelink\" onMouseOver=\"window.name = 'main'\" onClick=\"return popup(this, 'notes')\">Forgot Password</a><br>";
	echo "<input type=\"text\" name=\"email\" size=\"17\" value=\"Email...\" style=\"color: #999999\" onfocus=\"if (this.value == 'Email...') {this.value=''; this.style.color='#000000'}\">    ";
	echo "<input type=\"password\" name=\"pword\" size=\"17\" value=\"Password...\" style=\"color: #999999\" onfocus=\"if (this.value == 'Password...') {this.value=''; this.style.color='#000000';}\"> ";
	echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">";
	echo "</form>";
} else {    // If the form HAS been submitted
	$email = form($_POST['email']);
	$pword = md5($_POST['pword']); // Encrypts the password.

	$q = mysql_query("SELECT * FROM `signin` WHERE email = '$email' AND pword = '$pword'") or die (mysql_error()); // mySQL query
	$r = mysql_num_rows($q); // Checks to see if anything is in the db. 

	if (!$r) { // There is nothing in the db. The username/password do not match up.

		echo "<td width=\"108\" height=\"50\" align=\"left\" valign=\"middle\"> </td>";
      		echo "<td width=\"572\" height=\"50\" align=\"left\" valign=\"middle\">";
		echo "<form name=\"form\" action=\"index.php\" method=\"POST\" style=\"margin-bottom:0;\">";
		echo "                                                     <a href=\"signup.php\" class=\"bluelink\">Sign Me Up!</a>                 ";
		echo "<a href=\"pwordhelp.php\" class=\"bluelink\" onClick=\"return popup(this, 'notes')\">Forgot Password</a><br>";
		echo "<font color=\"#FF0000\"><strong>Incorrect Email or Password.</strong></font>   ";
		echo "<input type=\"text\" name=\"email\" size=\"17\" value=\"Email...\" style=\"color: #999999\" onfocus=\"if (this.value == 'Email...') {this.value=''; this.style.color='#000000'}\">    ";
		echo "<input type=\"password\" name=\"pword\" size=\"17\" value=\"Password...\" style=\"color: #999999\" onfocus=\"if (this.value == 'Password...') {this.value=''; this.style.color='#000000';}\"> ";
		echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">";
		echo "</form>";

	} else {      // If the username/password is invalid

		$_SESSION['logged'] = 1; // Sets the session.
		$_SESSION['email'] = $email;
		header("Location: main.php"); //   THIS IS LINE 111
		exit(); // Stops the rest of the script.

	}
}
}
?>

 

[/code]

 

And when I sign in with my user name and password, I get this warning message:

 

Warning: Cannot modify header information - headers already sent by (output started at /home/content/29/6879529/html/calhoun/index.php:9) in /home/content/29/6879529/html/calhoun/head1.inc.php on line 111

 

Can anyone help me out and tell me what I need to do to correct this?  Thanks in advance for your help!

The error is self explanatory. You have output going to the browser on line 9, and the header() is called after that.
