php question

[GSXdan]

OK so i finally got some free time to start learning php, and i get to this example(see code), but it wont work properly. The guess number counter should increment each time a incorrect guess is entered, but it doesnt. Any idea why?


TIA ^dan

Instead of:

PHP Code:

$num_tries = (isset($_POST[num_tries])) ? $num_tries + 1 : 0; 


It works with:

PHP Code:

if($_POST[num_tries]) {
  $num_tries = $_POST[num_tries];
} else {
  $num_tries = 1;
} 


With this method you'll need to do

PHP Code:

$num_tries++; 


in the number too large and number too small conditions.

I would do this because I don't think what he said gives a 0 before any guesses. Have a look see what you think but this definitely works.
