Now I gots me a header problem

Dolemite50

Hi,
I am getting this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/kyle/public_html/signinerr.php:13) in /home/kyle/public_html/signinerr.php on line 145

from this:

if ($pass != 1){
echo "Sorry, that password did not match.<br>
$please";}
else{
header("Location: signin.php");

I tried putting:
PHP_FLAG output_buffering on
in .htaccess but I get "Page cant be displayed" after doing so. Some other posts have mentioned a whitespace problem. Any way to check for that?

Thanks again everybody.

I also tried this:

else{
header("Location: http://www.mysite.com/signin.php");

but to no avail.

As the error says somthing is outputed before header("Location: in your script.

dolemite, the error shows line 145. That means you got 144 lines before your header call, but you are only showing 3 before it... What are the first 141 lines of the code? (Including any includes you may have before the header call)

Specifically around line 13, where it sayd the output is made.

I think I may have gotten past the initial error by adding

PHP_FLAG output_buffering on
to htaccess.

I now no longer get the
Cannot modify header information - error, but it wont redirect to the new page. If the page that I have the code on is called page1.htm and the header says to go to page2.htm, I get "Page cannot be found" and the url still says page1.htm.
Both pages are in the same foldr. I tried:
header("Location: http://www.mysite.com/signin.php");
and
header("Location: signin.php");

and they both give me "Page cant be found".

I know that you cant output anything to the browser before the statement but does this include graphics?

OK,
I think its safe to assume that outputting a graphic is outputting to a browser. (looks for embarrased emoticon) I assumed that it just meant you couldnt output anything in the PHP code before the header line.

Which brings me to my next problem.

If I have a signin page, and I want to have it go to errorPage if signin fails or signin2.php if it succeeds, which page should I use in the Form Action? I set the form action to the error page and I was trying to have it redirect to signin2.php if login was ok.

if ($pass != 1){
											echo "Sorry, that password did not match.<br>
											$please";}
												else{
												header("Location: [url]http://www.mysite.com/signin2.php[/url]");
												exit();

so that if login failed it would give an error and if login was ok it would redirect them to the signin2 page.

What are my options?

Thanks again.

I do all error checking in the login script. This is way it will just spit out the error above the login for the user enters incorrect data and there is no need to redirect.
