I think you want:
if (isset($variable)){}

Subject: [PHP-DB] passing variables
Hello all,
I have a login/register screen for my php/mysql db. When the page opens,
the user sees the log in screen but I have a button and reloads the same
page, hopefully with the register screen. I know I can simply check to see
if a variable is set with
if ($variable){} . This does not seem to work when I give an image a name
and link it to the same page. The image is named register and it links back
to the same page, so the page loads, I click on the register image , the
page reloads but the variable is not set.
Any ideas?
Thanks,
Eddie
