an error i cannot locate...

setora

okay... I have a php script on a major page of my site. its part of a dynamic link page [page.php?page=whatever] and its causing a little problem.
the script within itself is working just fine, the pages are showing up and i have the url displaying what i want it to. but behind the div layers of my site, in pretty plain view, is the following text,
"Warning: Cannot add header information - headers already sent by (output started at /home//public_html//head.inc:9) in /home//public_html//page.php on line 25"
I checked the coding on "page.php" at every line, one by one, especially at line 25 and nearby, and I checked the coding at "head.inc" and in neither did I find an error or a match that my appear in both files...
could somebody help me out?

You're either writing a header or setting a cookie (I'm not sure if cookies have their own messages, though) after you've already printed out HTML or whitespace. Look at line 9 in head.inc, that's where output theoretically started.

okay, i've looked at two different options here:
i checked line 9 in head.inc assuming that text between  are counted and found nothing.
alternately, i checked the same line of the same file assuming those types of text are not included. what i wonder now, does the "head" tag effect my php code? thats the only conclusion i could think of....

you seem to be including a page that tries to add more header information.

try removing the <head> tags from head.inc or page.php, depending on which isn't critical.

I've had this problem a lot in the past.
Instead of using header() to refresh to a different page, do this - it's works just as well:
<?
echo "<meta http-equiv='refresh' content='0; url=whatever.php'>\n";
?>

ANY HTML will make the header() not work.  is HTML, so it will screw it up.
No output what-so-ever is allowed before the header.

Also, s/he might not be redirecting, so it's not fair to assume that a meta tag will work. If s/he is, however, it might be a good suggestion. The header() function can print all sorts of information to the browser.

setora

alright, when i look at the code now, and at the suggestions here... i figure i could stand to drop "page"... i'll remember that for future use though, domo minna!

setora

now, if the code is modified so all headers that i need are included in page.php and there are no headers present in other pages, would the same error arise?
if so, how could the issue be fixed so i could keep the "page.php?page=whatever"? the idea is to keep certain urls hidden, under the guise mentioned before.

Mordecai

If all you're doing is including, then the headers shouldn't matter, and can be sent through the included page.
