So this is my problem;

I'm starting to learn PHP and how it works with SQL.  I run into problems non stop, and most of the time when i'm at my breaking point i find a solution via searching around the internet.  I've found a lot of tutorials on Updating data in an SQL database.  I now know how to update many rows at once with a single form, which is cool.  My main problem is i'm utterly FAILING at updating two or more columns in a table ..with the same form.    Basically i can display everything i want, but when i hit update..it all goes down hill.  My second page Update query info is where i bomb out...no matter what variation i try it just doesn't work.  If anyone can point me in the right direction to finish the code, i'd greatly appreciate it. I'll post a picture of what i'm trying to accomplish.

 

first page

<?
// Connect database.
$host="localhost"; // Host name.
$db_user="test"; // MySQL username.
$db_password="test"; // MySQL password.
$database="test"; // Database name.
mysql_connect($host,$db_user,$db_password);
mysql_select_db($database);

// Select all data records in table "name_list" and put them into $result.
$result=mysql_query("select * from Players");
?>

for whatever weird reason it won't let me edit again.  just wanted to say its safe to ignore most of the //'s...it was copied code where i changed variables.  also the code above is where only the player name column works..i left it at that so you could see how far i had really gotten.
