Also, your $actions variable is an array, but you are treating it as a string in your php script.

oh, and you could exchange all the if's with a switch/case, allthough that shouldn't give any problems either way.

call the variable $actions and not $actions[].
You'd have to call it $actions[] if you allowed multiple selections.

tried it like so

PHP Code:


		
			
$number1 = $_GET[number_one];

$number2 = $_GET[number_two];

$action[] = $_GET[actions];



if($action[0] == "+"){ $sum = $number1 + $number2 ;}

if($action[1] == "-"){ $sum = $number1 - $number2 ;}

if($action[2] == "/"){ $sum = $number1 / $number2 ;}

if($action[3] == "*"){ $sum = $number1 * $number2 ;}



echo $sum;

changed the html as well... i removed the "value" on the options.

Maybe you can try this

Code:

<html>

<head>

<title>The PHP Calculator :+)</title>

</head>

<body bgcolor="#FFFFFF">

<form action="Form_Handeling.php" method="post">

First Number: 

<input type="text" name="number_one" maxlength="3">

<br />

Second Number: 

<input type="text" name="number_two" maxlength="3">

<br />

Operator:

<select name="op">

<option value="+">Add those mofos!</option>

<option value="-">Subtract those mofos!</option>

<option value="/">Divide those mofos!</option>

<option value="*">Multiply those mofos!</option>

</select>

<input type="submit" value="Calculate!">

</form>

</body>

</html>

PHP Code:


		
			
<html>

<head>

<title>The result is....</title>

</head>

<body>

<?php



$number1 = $_POST['number_one'];

$number2 = $_POST['number_two'];

$action = $_POST['op'];



if($action == "+"){ $sum = $number1 + $number2 ;}

if($action == "-"){ $sum = $number1 - $number2 ;}

if($action == "/"){ $sum = $number1 / $number2 ;}

if($action == "*"){ $sum = $number1 * $number2 ;}
