[SOLVED] PHP Header Problem

[MsRedImp]

Hi guys, I wanted to include a header in my login script so that when somebody registers a new user it directs them to a certain page. The registration is happening and the users are being added to the database, but this piece of error code appears on the page and it doesn't redirect to any page:

 

Warning: Cannot modify header information - headers already sent by (output started at F:\wamp\www\euro\submitregister.php:13) in F:\wamp\www\euro\submitregister.php on line 111

 

Line 111 is where the header text is placed:

 

if(mysql_affected_rows() > 0)
{
$_SESSION['login'] = $_POST['login'];
header ("Location: registered.php");
}
else
{
$login = "User name already exists.";
}

 

Thanks for your help.

You have output on line 13 in submitregister.php and you are calling header() on line 111 in that file.

 

You cannot have any output before you use header.

 

What is on/around line 13  in submitregister.php?

Fyi there is a sticky about header errors, please read that before posting header errors

What do you mean by output?

 

Line 13 is where <title> begins:

 

<title>
<?php
$title = "Registering...";
echo "$title";
?>
</title>

 

Sorry about that, didn't see the sticky.

What do you mean by output?

 

echo "$title";

But I have echo outputs throughout my script, and want to use header during the form. Is there a way around this?

Well there is you problem. You are outputting text/html before you call the header function

 

Output is considered anything passed back to the browser, this can be text, html, newlines spaces etc. PHP will output anything before and after the PHP tags (<?php ?>) or any function your use within PHP that returns output eg echo, print, print_r, sprint etc.

 

You should do all processing before you output anything rather than do them both at the same time. If you dont want to change your script you can use output buffering as a dirty fix.

Oxymoron at what you are saying.  A header("location:"); changes your page location destroying all output, so why would you output before it.  Any other header defines something, so how can you define an object after making it.

Because somebody told me this would be a good function to use to direct my users to a new page upon different register procedures.

 

So do I have to put all of my html script inside the <php> tags?

 

Is there any other way of directing a user to a certain page depending on what happens when they register?

You have two choices, put your PHP code up top or use

 

<meta http-equiv="refresh" content="0; URL=yourpagehere.php">
