The code you have assumes that register_globals is on. Find the php.ini file, search within that file for register_globals then change where it says
to
and then see if the code runs.
This is a very common problem, the other post explains why those errors occur when register_globals is set to off and how to adjust your code so that you don't need register_globals on.

Try changing line 33 in login.php from
Code: Select all
if ($msg!="") { print "<p><b>$msg</b>\n"; }
to
Code: Select all
if (isset($msg) && $msg != '') { print "<p><b>$msg</b>\n"; }
and similarily line 3 from
to
Code: Select all
if (isset($msgcode) && (int)$msgcode>0)

1. Do you have a top.php file?
2. As before:
Code: Select all
if (isset($action) && $action=='nymedlem')
3. You can't use
header() if any output has been sent to the browser, so no HTML or whitespace can be sent before you try to redirect the page.

Use
isset to make sure that you don't get undefined variable notices. If you know that the variable has already been set then it won't be necessary. So you could have,
Code: Select all
if (isset($page) && $page != '') {
//Do something
if ($page == index) { // Don't need isset statement here
//Do something extra
}
//Finish off
}
It's not the best example but it shows the basic principal - if you've already tested to make sure a variable exists you probably won't need to test again within the same loop.

mysql_num_rows() just checks to see how many rows are returned from a query (in this case $result). It's not a variable it's a function so you don't need to check to see if it is set.
It would probably be a good idea if you had a look at some of the PHP tutorials at places like:
http://www.phpbuilder.com
http://www.devshed.com
http://www.zend.com
as well as the sites within the Developer Network.

And it happends again!

The idea with my site is that your suppost to register, and then get some friends, send emails to other persons that are registred at my site.
Problem nr.1
But now it seems like ive got problem again. First of all, if your new at my site and whant to register you clik the link that says
här,
then youll been taken to the "register part". But when i fill out my username and password i´ve been taken to the inloggpart, but it says
Du är nu utloggad, välkommen tillbaka! (You have been outlogged, welcome back!)
Problem nr.2
If i fill out wrong username or password, there shall come an errormsg that say
Wrong username or password!. But instead i got an php errormsg, that says:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in c:\program\apache group\apache\htdocs\xzone\dologin.php on line 6
Warning: Cannot add header information - headers already sent by (output started at c:\program\apache group\apache\htdocs\xzone\dologin.php:6) in c:\program\apache group\apache\htdocs\xzone\dologin.php on line 8
ive cheched the code, but i cant figgur it out, so im turning to you guys, one more time
