Need to add 2 number fields together in PHP

[alandobinson]

I am new to this - but have been trying to find a script to add 2 number fields together within a form using Frontpage. Any examples that I can use would be much appreciated.

<form action="process.php" method="post"> <input type="text" name="number1"> <input type="text" name="number2"> </form>

okay theres a form with just one text field. if you look at the first line, action is that page that the form data is being sent to. and method is either get or post. get means itll show the variables and thier names in the next pages url post wont do that.

PHP Code:

<?php

echo $_POST[number1] + $_POST[number2];

?>

echo simply outputs text to the browser. you could simply just do echo $number1; but if you dont have globals or something turned on in your php settings that script wont work. if you had your form set to get, then you would use echo $_GET[number1];

Really need to quote array keys to avoid possible issues with constants.

PHP Code:

echo $_POST['number1'] + $_POST['number2'];

i never use named constants, but i probably should have included that, just to stop him from getting into bad habbits that mite cause problems, my bad, alandobinson.

Yeah, I don't use them much either and when I do, they're pretty unique. (foo_app_VAR) PHP is pretty lax on that, so it should work, but as you said bad habits and that weird situation [in another app - in the future that may use foo_this as a constant] should be avoided.
