Question

Why won’t this print “success” when I submit the form? I’m pretty sure it should.

<?php
    if (count($_POST) > 0) {
        echo "success!!";
    }
?>

<form method="post" enctype="multipart/form-data">
    <input type="file" name="userfile" />
    <input type="submit" value="upload" />
</form>

At a guess, the submit field has no name, so it won’t be included in $_POST. Your file upload will be placed in $_FILES, see Handling file uploads.
