I'm trying to use php to validate my form. I would like to validate a product_name box for being not empty, a price box for being numeric and having a decimal, and a quantity box for being an integer. Right now I'm getting an error:
Parse error: syntax error, unexpected T_VARIABLE in C:\Program Files\IndigoPerl\apache\htdocs\process_games.php on line 60

I don't think I have how the price is validated correct either, how would I include the decimal point? I'm not sure if the way I have the code that the information will still be added to the DB if the error message for the price & quantity comes up. Maybe I should nest them with the product name?

You are missing a comma in line 60:

if (! preg_match('/^-?\d+$/',$_POST))

also php's is_numeric function should work just fine for checking if the number is numeric. For example change line 60 with:

if(!is_numeric($_POST) {
