Since you said you are just learning, I'll offer some great advice. Learn how to debug efficiently. By debugging, I mean you will need to be able to see the values of certain variables at certain points in the code. You should understand the values that you expect your variables to be. I used FirePHP to debug. It's a Firefox extension, and a PHP class, and it allows me to see the value of any variable I choose. It will even show you the values of arrays, objects, etc.

If you like using Chrome for your browser, you can try ChromePHP, although the debugging output is not as nice.

Once you can see the values of the variables, one of them will probably stand out as not making sense, or perhaps the value is blank when it shouldn't be. Debugging is how you find out what went wrong. If we debug this code for you, you will never learn to do it yourself.
