Calculator script.

[Independent]

This script was purely made out of boredom, but it was made by Independent of Habboxforum,
I hope this script comes useful in some way.

Newbies guide to installation..
You can just extract the files and it will work straight away.

http://www.calonuk.net/SCRIPTS/calculator.zip - Download it.
http://www.calonuk.net/calculator/ - Sort of demoish.

I know it's badly coded, but I was bored and I think someone could make good use of it.

Why have you used several files for a simple task?

Because it's craply coded.

<?php
$number1 = $_POST["number1"];
$number2 = $_POST["number2"];
$type = $_POST["type"];
if ( $type == "+" ) {
echo $number1 + $number2;
}
else {
if ( $type == "-" ) {
echo $number1 - $number2;
}
else {
if ( $type == "*" ) {
echo $number1 * $number2;
}
else {
if ( $type == "/" ) {
echo $number1 / $number2;
}
else {
exit( "idiot" );
}
}
}
}
?>


could do it with a lot less coding though.

Lmao, everyone corrects my code.
Thanks though, I may learn something from that code ^_^

You could do it with a switch and case also, as well as many other ways, I'm half buggered at the moment anyway, 36 hours with no sleep, and enough caffeine in me to last years.

Ouch. :D

Yeah, had a couple of friends over, beat GTA IV again. Swam a little in my pool, my eyes are about as big as golf balls.

<?php

$number1 = $_POST["number1"];
$number2 = $_POST["number2"];
$type = $_POST["type"];

switch( $type )
{

case "+":

echo ( $number1 + $number2 );

break;

case "-":

echo ( $number1 - $number2 );

break;

case "*":

echo ( $number1 * $number2 );

break;

case "/":

echo ( $number1 / $number2 );

break;

default:

echo 'Please go back and choose a valid option from the drop-down menu';

break;

}

?>
Switches ftw (I just read that Caleb suggested using them, I find them much easier to use for a script like this).

Thanks again!

I'm off to bed now, thanks for your code corrections Caleb/Simon.

I think they are a better alternative when parsing types, EX in this script would be the method that you are using to perform the calculation.

Or verifying that an option in a submission form is actually an option provided, and not someone submitting something that is either malicious, or just not acceptable.

:)

Could of at least put the buttons on the page and made it abit interesting, but celebs right with the switch & case method, its how I'd do it and many others.

[Jackboy]

I think you should make it into an actual calculator shape :P wud be a good idea

[Excellent]

Just echo what they put in.. say the fields were call blah 1 and blah 2.


elseif($submit){
$sum=$blah+$blah1;
echo "$blah+$blah1=$sum";

Even easier:



<?php
$number1 = $_POST["number1"];
$number2 = $_POST["number2"];
$type = $_POST["type"];

switch( $type )
{
case "+": $calculation = $number1 + $number2; break;
case "-": $calculation = $number1 - $number2; break;
case "/": $calculation = $number1 / $number2; break;
case "*": $calculation = $number1 * $number2; break;
default: "You ain't doin math boy.";
}

echo $number1 . " " . $type . " " . $number2 . " = " . $calculation;
?>

case "-": $calculation = $number1 - $number2; break;
case "/": $calculation = $number1 / $number2; break;

}

echo $number1 . " " . $type . " " . $number2 . " = " . $calculation;

Haha, love it.
