if (condition){
header("Location: login.php");
}
else{
do something
}


this works fine but there must not be anything printed out by the php
because header will be automaticly generated and this one that
redirects the browser will not work

ofcourse you can pass _GET variables this way if needed...

since you don't know if the user has js enabled - this is the best way
to do this

example


when username and password are entered and 'logon' button is pressed,
the process.logon.php page loads

->

read data from mysql
if (resultset has entryes) {
if (password from db = entered password){
header("Location: index.php?uid=somedata&another_var=another_val");
}
else {
// redirect to logon again - counting retryes is a good idea
header("Location: logon.php?uid=3&tryes=n"); }
// or print out something
print "wrong password" //better to exit to html and write something
nice looking
}
else {
// No souch user, redirect to 'register.php'
header("Location: register.php");
}
