PHP Header Issues

[dancer0913]

I keep getting teh following issue with headers...

Warning: Cannot modify header information - headers already sent by (output started at

I read in several places that this involves blank spaces ahead of the <?. I've check for this but still have the issue. I've posted the code below, and suggestions?

<?
include_once "../conn.php";
if (isset($_POST[s1]))
{
$q1 = "insert into job_employer_info set
ename = \"$_POST[ename]\",
epass = \"$_POST[epass]\",
ContactName = '$_POST[ContactName]',
position = '$_POST[position]',
YearEstablished = '$_POST[YearEstablished]',
capital = '$_POST[capital]',
employees = '$_POST[employees]',
CompanyName = \"$_POST[CompanyName]\",
CompanyCountry = \"$_POST[CompanyCountry]\",
CompanyState = \"$_POST[CompanyState]\",
CompanyZip = \"$_POST[CompanyZip]\",
CompanyCity = \"$_POST[CompanyCity]\",
street = \"$_POST[street]\",
CompanyAddress = \"$_POST[CompanyAddress]\",
CompanyPhone = \"$_POST[CompanyPhone]\",
CompanyPhone2 = \"$_POST[CompanyPhone2]\",
fax = \"$_POST[fax]\",
CompanyEmail = \"$_POST[CompanyEmail]\"";
$r1 = mysql_query($q1);
if(mysql_error())
{
$error = "<br><span class=TNA>Duplicate username: $_POST[ename]</span>";
unset($_POST[ename]);
}
else
{
$to = $CompanyEmail;
$subject = "Your account at $_SERVER[HTTP_HOST]";
$message = "This is your account information at $_SERVER[HTTP_HOST]\n\n username: $_POST[ename]\n password: $_POST[epass]\n\n\n Keep this information in a secure place. \n\n Thanks for your registration. We believe you will find the staff you need at [$_SERVER[HTTP_HOST]...] ";
$from = "From: $_SERVER[HTTP_HOST] <$aset[ContactEmail]>";
mail($to, $subject, $message, $from);
$_SESSION[ename] = $_POST[ename];
header("Location:thanks.php");
exit();
}
}
include_once "../main.php";
?>

Hello and Welcome to WebmasterWorld!

You cannot have any output to the browser before your HEADER() function otherwise the headers will not be able to be modified as they were already sent to the browser. Check to see if whitespace, HTML, etc has been echoed to the browser at any time before the header() call; you should also check your included files.

[dancer0913]

Is there a different way to do a redirect, after a POST operation that I might consider?

[eelixduppy]

You can use javascript or a meta-refresh tag however those both can be disabled on certain browsers. Your best bet is to use the header() redirect, just you have to make sure the browser hasn't received the headers before the call is all. It shouldn't be making too much of an issue.

Thank you for the quick replies. I've looked over what I have and the conn.php script which is included on line 2 is included below. Can you see where my problem area is between the php script above and the included one?

Again thx for your assistance.

[PHP_Chimp]

There is a thing about how much code to post in the forum charter. You may want to have a read of it.
If you do decide to post all of your code then you may want to at least wrap it in [ code] (no break after the opening [ for real use) tags. As I started looking then got bored after I scrolled the mouse 4 times and wasnt even half way down.

So although I only read part of your code there doesnt seem to be any print or echo statements in there (thank god for ctrl-f), however if there is ANY output before you start you php then the header wont work. So even if you have a blank line before your starting <?php tag you will not be able to send another header.
Please dont post the code for the entire page. Just check it for echo/print statements before the header or any html, even blank lines.

[dancer0913]

The transgression is noted, I will of course follow the rules of the forum in the future my apologies.

Thank you for the input. I've check the blank lines issue, using a couple different text editors just in case and their are no blank lines before <? in my primary or included php files. I have no print statements in either and the only echo statements I have are for a drop down list in a form. I have removed them as a test but still am getting the same issue.

Any additional thoughts?

[Tommybs]

You could try setting output buffering to on with ob_start(); before you send any other php code, this should allow you to send headers further down the code.
e.g
<?php
ob_start();
if($a == $a){
header("Location:page1.php");
}else{
header("Location:page2.php");
}
?>
Hope that helps.

[dancer0913]

No dice...

[Tommybs]

Just to confirm you put this in the original file at the top and not
in the conn.php file?

ie.
<?php
ob_start();
include_once "../conn.php";
//rest of your code.
?>

[dancer0913]

<?
ob_start();
include_once "../conn.php";
//rest of your code.
?>

Yes I have the following setup. Does the php after the ? matter?

[Tommybs]

No as long as ob_start(); is the first thing it shouldn't make a difference. Do you always use short tags i.e <? instead of <?php I know the shouldn't make a difference but then again I'm pretty sure ob_start(); should've fixed the problem as I'd encountered the same sort of issue as you before.

Have you tried creating some dummy pages with ob_start(); sending headers after echo statements just to check it is not somekind of server setup? Are you working on a local box or on a live server?
