Or better yet, post the full page code, please.
There must be nothing (even a blank space) sent to the Browser before the header(), or that error results. Check in your included/required files as well.

*edit*

Wrap the entire page in an ob_start() function to avoid a leak to the browser.

That would change the functionality -- there is nothing wrong with that particular line of code. The issue is about the header, not the include.

        case 'formAdd':
                    require_once("menu_adding_form.php");
                break;


should be:
<?php
     require_once("menu_adding_form.php");
     
    then  switch something  eg. switch($v){
       
       case 'formAdd':
                 


                break;


}
?>


If u need more assist let me know..

IF(){

yourcode
header('')
}elseif(){
yourcode 2
header('')

}
elseif(){
yourcode 3
header('')

}

same as for
Foreach(){} ect and also in a function myFunction(){}

Making sure none of the gloabal variables concides with another.

Yeah you're right, I've used Header(); quite a lot in my php pages, ofcourse I used it for different purposes, I've been trying to comment all the //Headers, and use print "somthing"; to replaces Header commands, it works fine, but Whenever I remove one of the comment lines, the warning will appear straight away.

I am sure I did something wrong, but I haven't found it yet. Maybe I already used Header in the file which is required in the php page. But I think you can use multiple Headers command on the same page or include or require, right?

Thanks a lot for your help but really I don't want to use javascript in this case, because  users can turn it off anytime, that means my website won't work ok without JS

Quyen,

define something like
$ready=<a href ='url'</a>;


then use javascript code  and refer the $ready in the javascript.

It is very easy. If you can not handle it, let me know and l will post you a full written java script code!


However, your warning seems like you have two

if(isset($_POST['xxxx'])) {
            header("Location: url");


if this is the case, do well to delete one since the error message is telling you that, the header has already sent a location and you are trying to overwrite on the older one....





"Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\vhosts\qwebdesign.net\httpdocs\admin\index.php:15) in C:\Inetpub\vhosts\qwebdesign.net\httpdocs\admin\user_manager.php on line 319"

check the line 319 of the user_mnager.php and the line 15 of the index.php. There is a conflict......>the index.php header you are trying to write has already been sent by the user_manager.php. And l bet you have included one of them in the other.


Best Regards

I know "Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\vhosts\qwebdesign.net\httpdocs\admin\index.php:15) in C:\Inetpub\vhosts\qwebdesign.net\httpdocs\admin\user_manager.php on line 319" is just a warning, not an error, but the thing is I don't want this warning to show up on the page, and whenever this warning is occurs, it stops redirecting. I will try to use Adam's solution and see what'll happen....

Thank you very much Adam,

After you understand how to use the meta tag you can then echo it to effectively redirect.

Ex. "   echo "<meta http-equiv="refresh" content="2;url=http://example.com">";   "
This will refresh the page at the new location ("http://example.com") in 2 seconds.

"http-equiv="refresh" " Is some what self explanatory, it will cause a refresh but if there is a url value in 'content' then it will refresh with a new location.

" content="2;url=http://example.com" " ' content="2 ' is where you can set the amount of time (in seconds) that the browser will wait before refreshing. ' url=http://example.com ' is where it will go upon refreshing.

It has proven a worthy alternative for me when  "header("location: ")" redirecting just doesn't seem to fit.

Hope it helps you out.

Well, I've tried that before but when you use headers to show a message before redirect to a page, actually you cannot see the message, the headers will execute straight away.

Yes, I suppose that's obvious and I should have thought of that !

It would be seen
1) if the header url didn't work
2) if you add in a delay to the header url function.
