phew... anyways the actual code cannot figure out the index for "hitme" on my radio buttons.

the show ships button won't work and it doesn't move through my for loops and if statements correctly.

it seems like it shouldn't be the hardest thing to fix but i'm a noob and the code is long and convoluted at this point.

if anyone has suggestions as to why it doesn't work please feel free to let me know.

You'll definitely need to localize the problem more before we can help reading your whole code, figuring out how it works, and then trying to bugfix it would take way too long.

Bendude14 · October 6, 2008

this line is wrong

echo "Allowed Misses: ".(20- $_SESSION['Allowed Misses'];

needs to be

echo "Allowed Misses: ".(20- $_SESSION['Allowed Misses']);

can you expalin more what problems you are having?

PFMaBiSmAd · October 6, 2008

You need to be learning php, developing php code, or debugging php code on a system where error_reporting is set to E_ALL and display_errors is set to ON in your php.ini to get php to help you with parse, warning, and notice errors. The posted code contains the following fatal parse error (which will only be shown if those two settings are set before the page is requested) -

Parse error: syntax error, unexpected ';' in your_file.php on line 334

I made some changes to your program, check it out:

1.- variables can not have spaces in the variable name.

2.- your numbers displayed on the Game board and the 'Show Ships' don't match, you have a list of numbers from 0 thru 9 and the other list is from 1 thru 10.

3.- I added some esthetics to the program...

4.- Check it out...
