header()

[basic_mind]

does anybody know much about the header(); tag its really pissing me off.
I have a script that I want to send an image back and it works perfectly with the header() except it doenst work?

okay I have a stats program that I'm working on if you do a direct request or a refresh it works fine all is hunky dory. but if you click on a link to the url. it shows the image like it should but it dosn't process any of the functions that lie before it. have put it at the first thing and the last thing in the script and it does't work properly where ever.

please help.

PS: the code works perfectly if I remove the header() though it doesn't display the image like I would like it to.

okay It actually works with ie but not with firefox any suggestions?

I'm guessing its a problem with FireFox's ability to compile the page correctly..strange- if no one else can help you (i cant because i think its firefox), report it to getfirefox.com

For now, do this:

<?php
$browser = $_SERVER["HTTP_USER_AGENT"];

// If "firefox" is found, redirect to a different URL
if (stristr($browser, "firefox")) {
header("Location: http://site.com/firefoxwarning.php");
exit;
}

// If no matches are found then exit the script and continue the page

?>

hope this helps

you want to paste some code so we can stop guessing?

Very doubtful. Let's see the code.

Well even though firefox maybe the leading web browser- it is still very new. It may be a coding error, or may be a browser error, but what ever it is, we dont know until you post your code.

I have been playing around with it but the problem is slightly different than I first thought. instead of not counting the stats from a link it will only count it once. and not again untill the browser has been closed and reopend. this occurs with firefox/mozilla/netscape

and does not occur with ie/opera ???

I'm sure its the header as it did not happen until I added that code.

okay the codes.

this is the tag that sends the info

<?php

echo <<<END
var refer = escape(document.referrer)+"";
if (!refer) { refer = "Direct Request"; };
var url = escape(document.location)+"";
//var userstring = navigator.userAgent;

var resolution = screen.width + "x" + screen.height ;
var colours = screen.colorDepth + "Bit";

tophp="&refer=" + refer + "&url=" + url + "&res=" + resolution + "&colours=" + colours;

imstring="<img src='http://www.statbox.co.uk/core/engine/addstat.php?";
prop="' alt='' border='0'>";

document.write(imstring+tophp+prop);
END;
?>

the script that process everything

<?php 
//includes
include("browser_array.php"); //browser information
include("os_array.php"); //os info

//information from the JS tag
$screenres = $_GET[res];
$screendepth = $_GET[colours];

you can view the collected stats at http://www.statbox.co.uk/demo.php

and a test link to the page.
