The error message looks like this
Warning: Cannot modify header information - headers already sent by (output started at /home/kabeet/public_html/flash/page_add.php:4) in /home/kabeet/public_html/flash/page_add.php on line 72
while my codes are the following:
71: if ($resultpage){
72: header("location:detail.php?name_id=$name_id#P$page_id");
73: exit();
74: }else{
What is wrong?
That error shows you have an output somewhere on the top by a different code.

function redirect($url) {
if (!headers_sent())
header('Location: '.$url);

echo 'window.location.href="'.$url.'";';
echo '</script>';
echo '<noscript>';

Where do I place the redirect url script? should it be before <html>? or at my header location function?
However you may well want to put all of your php code before all of your html (or after I guess, although I've never tried that). As it makes it easier to see what code is attached to that page. If you have blocks of php scattered throughout the page then it is more difficult for you to track down all of your code.
Sometimes it is unavoidable to have your php split up i.e. if you are breaking out of php to echo large amounts of information, but if you are not then put all of it in 1 place so it is easy to find.
If you have a lot of code then you could always include the php from an external file. So if you page is called page.html you have an included file called page.include.php or something like that, so you know what code goes with what page.
Delete the white space before the opening and ending php tags and the problem will definitely be solved.
If you make an analysis, you'll see that the <?php that begins your php code is preceded by an empty or white space. if It's not the case, this is true for the ending tag.
Delete that (or those spaces) and tell me if it doesn't work
