Get check box values inside array for use in posting form data

Question

So I have the following function with an array of variables that handles a profile form. All but one is a typical input with the exception of 'member-comptency[]'. It's a select field field with several possible values. Right now, the form saves, all the data comes through as expected with the exception of that field which simply returns a number.

I've tried in vain several times to modify this in different ways, but only produces a 'no-save' situation, or further non-descrip errors. I understand this field is an array itself, but not sure how to even ask google the right questions to get myself on track.

Any help would certainly be appreciated!

function getUMFormData(){
    $id = um_user('ID');
        $names = array(
            'member-company',
            'member-phone',
            'member-website',
            'member-competency[]',
            'member-contact-billing-name'
        );

        foreach( $names as $name )
        update_user_meta( $id, $name, $_POST[$name] );
}

This is not a WordPress-specific question, and without seeing your form code it's hard to say, but what is obviously wrong is that you are referring to the variable with the [] in the name. Try removing them and test again. If not, I suggest var_dumping the $_POST variable and seeing what it contains and working from there.
