PHP Error

[jrmontg]

Couple of things: This works under Apache which is my testing server but not IIS where the web site is hosted.

I am getting this error:

Warning: Cannot modify header information - headers already sent by (output started at E:\internet_new\userareas\login.php:9) in E:\internet_new\userareas\login.php on line 41

I have one page index.php that has a login form. When submitted this goes to login.php to be validated. This is where I am getting the error.

Thanks for your help

The error message you get appears when you do something like this:

echo "foo";

header(Location: redirect.php...)

Go through you code and make sure you are not sending anything out before you redirect or do anything else to the headers. Also if you are using cookies double check your order in how your reading/write them, that could also give the error.

HTH!

Your testing server probably has output buffering set to On in php.ini
Turn output buffering off.
Instead design your code such that headers (e.g. by using [man]header/man or [man]setcookie/man)are sent before any output.
At worst, you can still implement output buffering within your script itself, rather than making it set globally across all PHP scripts.

laserlight.. The testing server is the one that works. I went to the IIS webserver and changed that line to

output_buffering = OFF
;output_buffering = 4096

But that did not fix the problem.

Here is the code for the page

<?php

session_start();
?>
<?php require_once('../Connections/connUserareas.php'); ?>
<?php require_once('../Connections/mySQL.php'); ?>

<?php

$myUsername_rsLogin = "0";
if (isset($HTTP_POST_VARS['username'])) {
$myUsername_rsLogin = (get_magic_quotes_gpc()) ? $HTTP_POST_VARS['username'] : addslashes($HTTP_POST_VARS['username']);
}
$myPassword_rsLogin = "0";
if (isset($HTTP_POST_VARS['password'])) {
$myPassword_rsLogin = (get_magic_quotes_gpc()) ? $HTTP_POST_VARS['password'] : addslashes($HTTP_POST_VARS['password']);
}
mysql_select_db($database_connUserareas, $connUserareas);

$query_rsLogin = sprintf("SELECT Username, Password FROM companies WHERE Username = '%s' AND Password = '%s'", $myUsername_rsLogin,$myPassword_rsLogin);
$rsLogin = mysql_query($query_rsLogin, $connUserareas) or die(mysql_error());
$row_rsLogin = mysql_fetch_assoc($rsLogin);
$totalRows_rsLogin = mysql_num_rows($rsLogin);

mysql_select_db($database_mySQL, $mySQL);
$query_rsNews = "SELECT * FROM news WHERE onFront = 'Y'";
$rsNews = mysql_query($query_rsNews, $mySQL) or die(mysql_error());
$row_rsNews = mysql_fetch_assoc($rsNews);
$totalRows_rsNews = mysql_num_rows($rsNews);

if($HTTP_POST_VARS['action']=="login"){
if($totalRows_rsLogin==0){
$errorMessage = "Sorry, you login information in incorrect";
mysql_free_result($rsLogin);
} else {
mysql_free_result($rsLogin);
session_register("Username");
$HTTP_SESSION_VARS['Username'] = $HTTP_POST_VARS['username'];
header("Location: home.php");
}
}
?>

Yep, just changing that line wouldnt fix your code.
It would help make parsing slightly faster.

To fix your code, you need to ensure that no output is written before the last header is sent.
Output includes blank lines.

<?php require_once('../Connections/mySQL.php'); ?>

<?php 

There's a blank line right there.

Now, instead of using so many <?php and ?>, you should reduce these to only what you need.

<?php
session_start();

require_once('../Connections/connUserareas.php');
require_once('../Connections/mySQL.php');

$myUsername_rsLogin = "0";

Got it, thanks that fixed that error.

However, now the session is not being "passed". I have this line on the next page: <p>Welcome <?php echo $row_rsUser['CompanyName']; ?></p>

Again it works on my testing computer. I tried getting rid of all the PHP tags like before but that did not fix. I think it could be a setting in php.ini but I am not sure.

Thanks
