it sounds like your class does not exist (or some function or class it relies on).

the parameter to be passed into the function so my php code looks like: <?php $a = new Validation; $a->checkEmpty($_POST["name"]); ?>

1. check your error log for an error messge. 2. determine if the class exists at the time that the above code is run e.g. with class_exists('Validation'). 3. determine if $a is actually a Validation object (i.e. the creation of a new object succeeded)

I know how to call functlions, I just just don't know how to do it in PHP.

Based on the rest of your question, I think you mean methods, not functlions. :-) If you're struggling with syntax, you should take one step at a time. Try this: <?php class myClass {

    function myMethod()
    {
        echo '<p>myMethod()</p>';
    }

} $myObject = new myClass; $myObject->myMethod(); ?> That should help you with any syntax problems, but I suspect your problem has more to do with logic than with syntax.

if (isset($submit)) { class Validation {

/* ... */

} } else {

/* ... */

$v = new Validation; $v->checkEmpty($_POST["name"]);

If the form is submitted, define the class, else use the class. That doesn't sound right... Hope that helps. Chris -- Chris Shiflett Brain Bulb, The PHP Consultancy http://brainbulb.com/
