A Test To See If You Write Sloppy Software Page 4

Inside of functions, you should also handle all errors. The easiest thing to do is set a $feedback
variable, and in your header/footer template, you always echo out that $feedback variable if it
exists. This has worked well for me.

<?php
function my_function () {
    global $feedback;
    //code
    if ($error) {
        $feedback .= 'Could Not Perform Operation XXX';
        return false;
    } else {
        $feedback .= 'Operation XXX Successfully Performed';
        return true;
    }
}
?>

Then you simply call these functions like this:

<?php
if (my_function()) {
    //do something
} else {
    //handle error
}
?>

Of course, the same error checks should be performed on database updates, inserts, and deletes.
Give yourself 1 point if you check all your database queries and provide proper feedback to the user.
