Anyone Figure this out?

[rockofaith]

okay..the ob_start() think worked great. But I had to change the php code around because it wasn't giving an error message for each text box that has an error.

The website is - http://stu.aii.edu/~jas5317/php/register.php

and the php code is -

<?php // Script 8.10 - register.php (second version after Script 8.9)
// This page lets people register for the site (sort of).

// Address error handing.
ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);


if ( isset ($_POST['submit'])) {

$problem = FALSE; // No problems so far.

// Check for each value.
if (empty ($_POST['username'])) {
	$problem = TRUE;
	print '<p>Please enter a username!</p>';
}

if (empty ($_POST['first_name'])) {
	$problem = TRUE;
	print '<p>Please enter your first name!</p>';
}

if (empty ($_POST['last_name'])) {
	$problem = TRUE;
	print '<p>Please enter your last name!</p>';
}

if (empty ($_POST['email'])) {
	$problem = TRUE;
	print '<p>Please enter your email address!</p>';
}

if (empty ($_POST['password1'])) {
	$problem = TRUE;
	print '<p>Please enter a password!</p>';
}

if ($_POST['password1'] != $_POST['password2']) {
	$problem = TRUE;
	print '<p>Your password did not match your confirmed password!</p>';
} 
if (!$problem) { // If there weren't any problems...

    header ('location: http://stu.aii.edu/~jas5317/php/thankyou4.php');

} else { // Forgot a field.

    print '<p>Please try again!</p>';

}

} // End of handle form IF.

print '<div id="leftcontent">';
    print "<h4>Register here to access Fred's Forum and to purchase CD's</h4>";

// Display the form.
print '<form action="register.php" method="post"><p>';

print 'Username: <input type="text" name="username" size="20" value="' . $_POST['username'] . '" /><br />';

print 'First Name: <input type="text" name="first_name" size="20" value="' . $_POST['first_name'] . '" /><br />
Last Name: <input type="text" name="last_name" size="20" value="' . $_POST['last_name'] . '" /><br />
Email Address: <input type="text" name="email" size="20" value="' . $_POST['email'] . '" /><br />';

print 'Password: <input type="password" name="password1" size="20" /><br />
Confirm Password: <input type="password" name="password2" size="20" /><br />
<input type="submit" name="submit" value="Register!" /></p>
</form>';

// Complete the HTML formatting stuff.
print '</div>'; 

?>

Thanks in advance.

You cannot call header() if any output of any kind has already been sent. This includes HTML not within your <?php tags, blank lines before the first <?php tag, and anything in your actual PHP code that sends output (echo, print, etc.). If you cannot change the logic/layout of your page to do the PHP code that includes the header() call before any output, then you can consider using the output buffering functions to get around this. See ob_start() for more info.

I didn't realize ob_start was in my textbook. Let me look into it further. Thanks much

Put the checks at the beginning of the page(no output at all before this!)

$error = '';
if ( isset ($_POST['submit'])) {

$problem = FALSE; // No problems so far.

// Check for each value.
if (empty ($_POST['username'])) {
    $problem = TRUE;
    $error = '<p>Please enter a username!</p>';
}

if (empty ($_POST['first_name'])) {
    $problem = TRUE;
    $error = '<p>Please enter your first name!</p>';
}

if (empty ($_POST['last_name'])) {
    $problem = TRUE;
    $error = '<p>Please enter your last name!</p>';
}

if (empty ($_POST['email'])) {
    $problem = TRUE;
    $error = '<p>Please enter your email address!</p>';
}

if (empty ($_POST['password1'])) {
    $problem = TRUE;
    $error = '<p>Please enter a password!</p>';
}

if ($_POST['password1'] != $_POST['password2']) {
    $problem = TRUE;
    $error = '<p>Your password did not match your confirmed password!</p>';
}

if (!$problem) { // If there weren't any problems...
    header ('location: http://stu.aii.edu/~jas5317/php/thankyou4.php');
    // echo $error; <- This is not needed here

}
}

..And later in the script(the form):

if (!empty($error))
	echo $error;

// Here continues 
print '<div id="leftcontent">'; 
...

My thankyou page has this script...

 
$username = $_POST['username'];
$password = $_POST['password'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];

print "$name,<br/>";
	print "<br/>";
print "Thank you for your registering.<br/>"; 
print "<br/>";
print "Please make a note of your username <b>$username</b> and your password <b>$password</b>. You will use these to login for entering comments in the forum, to add an entry to the guestbook, and when you're ready to purchase a CD.<br/>";

But I don't know how to pass the variables to this confirmation page when everything goes okay with the form. Which is why I have the

if (!$problem) { // If there weren't any problems...

    header ('location: http://stu.aii.edu/~jas5317/php/thankyou4.php');
