Code:

No syntax errors detected in /var/www/html/test.php

its a notice not an error, not to mention fatal error. your php.ini has been setup to show notices. however as far as i can see you are using some windows apache server so i have no clue where your php.ini is located. you could leave it like that while developing and when ready all you have to do is add

Code:

error_reporting(0);

at the top of your file and that will fix the problem.

I agree with alxkls. The error message could mean that you are trying to read a variable that has not been set. This is only a warning and does not affect your script, it should behave as normal, you can change whether they are displayed or not via the php.ini file or by using error_reporting.

But checking to see if the variable has been set using isset() is and idea. If it is null you will get the notice you are receiving unless you turn error reporting off.

if(isset($_POST['email'])) {

Setting error_reporting to 0 does not fix the errors (or 'notices, if you want). It just hides them, and at the same time encourages bad coding.

As sonic10 pointed out, use isset() on user defined variables to make sure they exist before you attempt to use them.

Every time PHP throws a warning, error, or notice, it's been written to a log file. That means, every time is has to open, write and close the file. That makes your script run slower.

I would invert the isset() and then use die() to kill the script if the user hasn't entered an email or a password. And I agree with Nico, never hide the warnings/errors/notices.
