Whatever, the answer is still the same: You cannot have anything between the beginning of the file and your ?php tag. Not even whitespace (spaces, tabs, newlines etc). Check all your include() files as well for any stray space. -- Jason Wong - Gremlins Associates - www.gremlins.com.hk Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* Lead us in a few words of silent prayer. -- Bill Peterson, former Houston Oiler football coach */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] redirect browser
make sure that this script is not insterted into an html document but
it's a stand alone page eg. checkstudent.php. When the student submits
their number your form should bring them here (form
action=checkstudent.php method=post) and the page will do its job.
Make sure however that there is no output (don't print to screen) on that
page except error messages in your if statements or you will get errors.

I had developed the web-based survey for student.
And I need to check that each only fill in the form once time.
So I write following code to check if the student number
exist in the database or not.
if yes, don't let them to fill in again.
if no, redirect the browser to the page for them to fill in.
=
?php
$db = mysql_pconnect(localhost, survey, survey);
if (!$db)
{
echo Error: Could not connect to database.;
exit;
}
mysql_select_db(survey);
$query = mysql_query(select * from surveydb where studno = '$studno');
$result = mysql_num_rows($query);
if ($result=1)
{
echo Student Number $studno already existed in the database.brbr
.You don't need to input again!;
}
else
{
header(Location: http://www.XXX.edu/index.php;);
exit;
}
?
=
the code can check the student no. are exist in database or not
but the browser don't redirect to the page if student not exist
in database and display the following error code:
Warning: Cannot add header information - headers already sent
by (output started at c:\html\html\check.php:4) in
c:\html\html\check.php on line 42
I had no idea about this.
Can anyone tell me what's wrong of my code?
Thx!
Joe
