Logocal or in php? [on hold]

I´ve got two input fields that can be filled out "cce_resource_link" and "cce_resource_file".

Now I want, if one is filled out to display content, but its now working:

    <?php if($this->field('cce_resource_link')->value()) or $this->field('cce_resource_file')->value()): ?>

<?php endif;?>

Thx
