textfield1+textfield2

[skoff]

is there a way to make an addition with two text field with the values that they have in them.
Example if my textfield1 contain 1 and the textfield2 contain 3 i would like to have the result 4 in a textfield3.

<?php
$result=floatval($_REQUEST["textfield1"])+floatval($_REQUEST["textfield2"]);
?>

<input type="text" name="textfield3" id="textfield3" value="<?php =$result;?>">

Hi all,

Unless I misunderstand the context of this, I would urge you to substitute the _REQUEST for _POST, this is purely for a more secure approach, but if this is just for development, you should be fine, but honestly try not to use _REQUEST on a live server as you will reveal lots of information about your site.

Cheers,
