Cannot modify header information??

y0y014

I am trying to include the login box from a user script I found. 🙁 I keep getting the below error.

Warning: Cannot modify header information - headers already sent by
(output started at /home/lostpro/public_html/ss/header.php:4) in /home/lostpro/public_html/ss/loginbox.php on line 3

Here is the code of the page I am trying to include...


<?php
include("config.php");
 setcookie("page","$PHP_SELF",time()+155555);
if($loged=='yes')
{
?>
<table width="100%" border="0">
<tr><td>
<?php echo $lang[hello] ?> <?php echo $name ?>.
<?php echo "$lang[logedas] $username"; ?> 
</td><td>
<?php include("new_messages.php"); ?><BR>
<a href="editaccount.php"><?php echo $lang[editaccount] ?></a><BR>
<a href="changepass.php"><?php echo $lang[changepass] ?></a><BR>
<a href="logout.php"><?php echo $lang[logout] ?></a>
</td></tr></table>
<?
}
else
{
?>
<form action="login.php" method="post">
<?php echo $lang[username] ?> : <input type="text" name="username"> <BR>
<?php echo $lang[password] ?> : <input type="password" name="password">
<BR><input type="submit" value="<?php echo $lang[loginbutton] ?>">
<br><br><center><a href="register.php"><?php echo $lang[register] ?></a> | 
<a href="lostpass.php"><?php echo $lang[forgottenpassword] ?></a></center>
</form>
</td></tr></table>
<?
}
?>

This is a FAQ --- check the FAQ in the newbies forum for more info.

No output (to browser) is permissible prior to setcookie, header, session_start(), etc.

This includes any whitespace. Check your script and the included file ....

I don't know what you mean really... I am kinda new to PHP... I should have posted under the Newbie section... but could you explain what you are talkin about, a bit more??

The error message says it all.

From here, it looks as if the code your posted in your first post is being include()ed in a master file, which has above it another included file "header.php".

"Header.php" contains browser output (echo statements, HTML code, etc.) or else accidental "whitespace" and you can't output anything to the browser prior to setcookie(), session_start(), header(), etc. --- so PHP refuses to act on your script and shows you the error message instead.

One thing I've grown to love about PHP --- an error message means exactly what it says. 🆒

Definitely in this [man]faq[/man]. Under "Using PHP" if I recall.

And of course there's the good old search button.
