Hi All
I seem to be writing a lot of this:
//======== SCRIPT =========
$var = $_POST['var'];
// validate $var
$foo = new foo;
$foo->setBar($var);
//======== CLASS ==========
class foo {
public function setBar($var) {
// validate $var
}
}
As you can see, the "issue" is that I am validating the input in my script, and then again in my class... surely unwanted duplication!? Obviously (I think!), I need to be validating at the level of my class, so does anyone have a pattern / strategy to help ease the pain... a way of using the validation in the class to validate the script and return meaningful errors to the user?? Throwing errors and forcing the script to catch them perhaps?
I have tried a few validation classes etc and they have not really addressed this issue. Perhaps I should just live with it and get on with it! :)
Many thanks for your help, David
