Question

I’m trying to make a BASIC roulette script.

Is there anyway to get the submitted results of a form using PHP? In fact I know theres a way, but i can’t find out how to do it.

So say if my form had several fields I want the result to loop through and show me which fields were filled and the numbers in each.

UPDATE: And say the form has about 40 fields, would I have to name each one in the loop? Any easier way?

If your form looks like this:

<form method="post" action="result.php">
    <input type="text" name="foo">
</form>

In result.php you can use the global variable $_POST and loop through it if you want:

foreach($_POST as $name => $value) {
    echo $name . ' = ' . $value;
}

If your form has 40 fields, you still need to name them all, but you can automate the process of naming and retrieving them with a loop. For example, if you wanted to create a sum with the value of all the fields, you could name them number1, number2, etc and do:

$sum = 0;
for($i = 1; $i <= 40; $i++)
    $sum += $_POST['number' . $i];
