[SOLVED] redirect..cont

[ultratek]

cleaned up the code....i cannot figure out why lines 61 through 72 do not work for me to redirect to my thanks page...in the same directory....i get a blank page after i submit the register.php:

<?php



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

require_once ('mysql_connect.php');

$errors = array();


if (empty($_POST['first_name'])) {
	$errors[] = 'You forgot to enter your first name.';
} else {
	$fn = escape_data($_POST['first_name']);
}


if (empty($_POST['last_name'])) {
	$errors[] = 'You forgot to enter your last name.';
} else {
	$ln = escape_data($_POST['last_name']);
}


if (empty($_POST['email'])) {
	$errors[] = 'You forgot to enter your email address.';
} else {
	$e = escape_data($_POST['email']);
}


if (!empty($_POST['password1'])) {
	if ($_POST['password1'] != $_POST['password2']) {
		$errors[] = 'Your password did not match the confirmed password.';
	} else {
		$p = escape_data($_POST['password1']);
	}
} else {
	$errors[] = 'You forgot to enter your password.';
}

if (empty($errors)) {




	$query = "SELECT user_id FROM users WHERE email='$e'";
	$result = mysql_query($query);
	if (mysql_num_rows($result) == 0) {


		$query = "INSERT INTO users (first_name, last_name, email, password, registration_date)
		VALUES ('$fn', '$ln', '$e', SHA('$p'), NOW() )";
		$result = @mysql_query ($query);
		if ($result) {




		$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);


		if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) {
			$url = substr ($url, 0 ,-1);
			}


		$url .= 'thanks.php';

		header("location: $url");
		exit();

	} else {
		$errors[] = 'You could not be registered due to a system error. We apologize for any inconvenience.';
		$errors[] = mysql_error() . '<br /><br />Query: ' . $query;
	}

} else {
	$errors[] = 'The email address has already been registered.';
}

}

mysql_close();

} else {

$errors = NULL;

}


$page_title = 'Register';
include ('./includes/header.html');

if (!empty($errors)) {
echo '<h1 id="mainhead">Error!</h1>
<p class="error">The following error(s) occurred:<br />';
foreach ($errors as $msg) {

Put ob_start(); on the first line

 

Then ob_clean(); before you set a header.

 

If you try to set a header after you have echoed something it won't let you.

 

See headers_sent in PHP manual for reference.

Or better yet, fix your code.

 

It makes no sense to have output to the browser if you will just use a HEADER anyways.

[mtoynbee]

That too

[revraz]

Blank pages are indicators that you have errors in your code (or there is just nothiing to display).  Make sure you have error reporting on and that you are displaying them.

[ultratek]

there are no echo statements before the header()

and i moved the $page_title and include() to after the header()

as the lesson instructed...

[ultratek]

thank you guys for your help..

 

i still cant figure out why i am getting a blankpage when i submitt the register.php

the script is written just like the book's...

 

i am testing on my server...http://www.justinvenablephoto.com/practice/register.php

Show the code where you turned this on.

error:

[revraz]

Tells you the exact problem.  Output on line 28 of mysql_connect.php is causing a problem with your HEADER line on 71.

[ultratek]

didnt thinkabout the require file having trouble...

sure enough...whitespace..

 

thanks for all the help guys
