Undefined Index Question [Resolved]

[Epiales]

Okay, I have a simple dice game where they can place a bet and if they match 2 or 3 dice, they win gold. Problem is, is I always get the error below. I'm not sure why.

Notice: Undefined index: bet in C:\xampp\htdocs\login3\dicegame.php on line 219

It's just like with any other If isset GET statment, but this one isn't working properly and I don't know why. I've used forms a million times and the if isset statement and never had this problem.

Try adding

Code: Select all

if( !isset( $_GET['bet'] ) ) {
    $_GET['bet'] = 0;
}

before you use $_GET['bet'] the first time

Yeah, that worked. Not sure why I didn't think of it lol!

Thank you again
