I was eally bored the other day. So I decided to make a php calculator just out of the blue. I set it up and it works really good. You can see mine here. Ill give you guys the source code too if you want it. Here it is...
Name this calculate_forum.html
CODE
<html>
<head>
<title>Calculation Form</title>
</head>
<body>
<form method="post" action="calculate.php">
<p>Value 1: <input type="text" name="val1" size="10"></p>
<p>Value 2: <input type="text" name="val2" size="10"></p>
<p>Calculation:<br>
<input type="radio" name="calc" value="add"> add<br>
<input type="radio" name="calc" value="subtract"> subtract<br>
<input type="radio" name="calc" value="multiply"> multiply<br>
<input type="radio" name="calc" value="divide"> divide</p>
<p><input type="submit" name="submit" value="Calculate"></p>
</body>
</html>
Name this calculate.php
CODE
<?php
if (($_POST[val1] == "") || ($_POST[val2] == "") || ($_POST[calc] =="")) {
header("Location: calculate_form.html");
exit;
}
if ($_POST[calc] == "add") {
$result = $_POST[val1] + $_POST[val2];
} else if ($_POST[calc] == "subtract") {
$result = $_POST[val1] - $_POST[val2];
} else if ($_POST[calc] == "multiply") {
$result = $_POST[val1] * $_POST[val2];
} else if ($_POST[calc] == "divide") {
$result = $_POST[val1] / $_POST[val2];
}
echo "<title>Calculation Result</title>";
echo "<p>The result of the calculation is: $result</p>";
echo "<p><a href=\"calculate_form.html\" target=\"_self\">Do Another</a></p>";
?>
Then upload the files to your server and go to www.yourdomain.com/calculate_form.html and enter 1 number in variable 1 and another number in variable 2. Then select a mathmatical method, then press calculate and then your answer will pop-up in a new page. The just click 'Do Another' to do another problem. Comments are appreciated.
