[PHP] Avoiding several windows with the same session

[Roman Sanchez]

I place

session_start();
if (!session_is_registered('somevar'))
{
header('location: login.php');
exit();
}

at the top of all my pages to prevent people to view pages before they log
in. However, once thay have logged in succesfully, they can ctrl-U in IE to
open a new window. This new window 'inherits' the session id and hence it
does not redirects to the login page. Is there any way to avoid this
situation so that people cannot have several windows with the same session
open?

Thanks!

I just cut and pasted your code, commenting out the include()s
you say aren't important and the $name variable prints out fine.
Are you sure your not overriding its value in one of the other included
files?

On the other hand, terés no need to use global, this is only when you want
to use
global variables _inside_ a function.

Cheers!

Since MySql version 3.23 you can use "show table status" to show a lot of
information for all tables in a database, including the number of rows.

[PHP] Re: table cell space under image in IE

[Roman Sanchez]

If you write




the CR-LF before  counts as an space wich wraps to the next line. It
might be helpful to write

 (in the same line)

instead.

Frankly, it´s not on topic at all and no matter how you produce the final
html output you should know how to deal with it.

You don'y say which cell has the problem but, apart from placing the closing
td right after the image try to move the closing form tag out from the
table. At least in IE,  _allways_ produces that extra space no matter
what you do unless you use style sheets to set the form's bottom-margin
yourself.
