PHP Help?

[entity]

Hi, I've only just joined; but I've been a part of the PHP phenomena for quite a while now. Well I've been scripting a code for an Online RPG (Adventure Quest); this code allows you to work out stats. Anyway, I've been working quite hard on this code but I have finally come to a full stop on it. My problem is that stats can only be in 5's so 5 all the way up to 175 (unless your a staff member you can get anything as long as it is a multiple of five), my problem is I don't know how to make a validation code that will only allow multiples of five. Any help on this would be greatly appriciated as this is the first code I've written without copying parts here and there.
Thank you very much.

i dont know your approach on this (how your numbers is sendt) but here is something for you to work on.
It wouldn't surprice me if there is an easier way though...
In this i've assumed that numbers sendt can be any sum of numbers

Test it with page.php?n=105 or whatever
[code]
<?

$number = $_GET['n'];
settype($number,"integer");
$max = "175";

if(!empty($number))
{
if($number > $max)
{
  print "The number is higher than $max";
}
else
{
if(substr($number, -1, 1)== "0" OR substr($number, -1, 1)== "5")
{
  print "Approved";
}
else
{
  print "Declined";
}
}
}
else
{
  print "No number is present";
  // note that a single 0 in $number will be seen as no number in this case
}
?>
[/code]

Well that is pretty cool, would it help if I posted the code up? I'll do it anyways:

It's pretty simple (and admittedly quite chunky) but it works well; I just need a little help with the finishing touches! ^_^

Hey! I've played your game before. Pretty cool! So basically what you want to do is only want to have 5,10,15,20,25,30,35....175 ? how about this:

[code]
<?php
   if ($_POST['blah']) {
      if (is_numeric($_POST['blah'])){
         echo $_POST['blah'];  
           if (($_POST['blah'] % 5) == 0) {
            echo " is divisible by 5.";
           } else {
              echo " is NOT divisible by 5.";
         }
      } else {
         echo "Please enter in a valid number";
      }
   } else {
        echo "Please enter in a number";
     }    

   echo "<br><br>";
   echo "<form action='$PHP_SELF' method ='post'>";
   echo "<input type = 'text' name='blah' size ='5'>";
   echo "<input type = 'submit' value='check num'>";
   echo "</form>";
?>
[/code]

now it's not really that long. it's just an example of it in action. the only line that you really need to pay attention to is this:

[code]
if (($_POST['blah'] % 5) == 0) {
[/code]

this takes the number in question ($_POST['blah]) and divides it by 5 and returns the remainder. if the remainder is zero, then it echos 'this number is divisible by 5. otherwise, it is not divisible by 5.

Now, as far is only MAKING it divisible by 5, well you can just round up to the next divisible number. for example:

[code]
$num = 213;
$blah = ($num % 5);
if ($blah != 0) {
   $num = $num + $blah;
}
[/code]

I think you are probably php saavy enough to figure out how to make use of this spiffy little operator [img src=\"style_emoticons/[#EMO_DIR#]/smile.gif\" style=\"vertical-align:middle\" emoid=\":smile:\" border=\"0\" alt=\"smile.gif\" /]

[entity]

Lol, it isn't my game, I'm just making a fan based web site and this going to be one of the codes that I use Well I'll try this out! &_&

[entity]

Sorry about the double post guys, but thing is I've just noticed something about my script and I've been working on this for aggggges; well I'm doing quite a few calculations in there, but quite a few seem to come out wrong,
[code]
$SBtH = round($dex / 16 + $str / 16 + $luck / 20);
[/code]
Well what is supposed to happen there
is this:
$dex, $str and $luck are all brought from a form, well their numbers are
$dex = 100
$str = 100
$luck = 20
so what happens is:
100 divided by 16 = 6.25
+
100 divided by 16 = 6.25
+
20 divided by 20 = 1

once added altogether this should equal
8.50 rounded up to 9 but what I get is 17 which is wrong but so is the nine... what it is supposed to be is 14... what is going on here? Can anyone give me a few hints please?

[AndyB]

[code]$dex = 100; // normally retrieved from the $_POST array
$str = 100;
$luck = 20;
$SBtH = round($dex / 16 + $str / 16 + $luck / 20);
echo $SBtH;[/code]
That produces the correct answer (14). If your code doesn't then there's either something tragically wrong with your code or maybe you're looking at an older version or it's not uploaded to the server or something.

If it really doesn't work - can we see some of the code that processes the form data

[entity]

Well thanks for the help I've got that working now; I've just gotta get Crayon Violent's thing working now, hopefully!

[entity]

Well, I'm still hving problems, I can't seem to find a way to implement Crayon Violent's idea, I'll post the code and could you try and see how it could be fixed? Cheers ^_^

PS: Sorry for all the double posting by the way!
