Using the documentation from this page: http://www.advancedcustomfields.com/resources/field-types/checkbox/

Colors: <?php echo implode(', ', get_field('field_name')); ?>

I want to get the multiple checkbox options as class names from a given user, something like this: http://www.advancedcustomfields.com/resources/how-to/how-to-get-values-from-a-user/

echo '<ul class="' . implode(', ', get_field('region') , 'user_'. $author->ID) . '">';

So that the outcome should look something like this:

<ul class="Limpopo Gauteng NorthernCape">

Error I get is:
Warning: implode() expects at most 2 parameters, 3 given in …. filename
