Answer 1

See where you declare array

it's may be out of function

or inside of other function

try to declare it in function or make array global

You could try this:

    // SELECT BOX
    array(
        'name'     => __( 'Select', 'rwmb' ),
        'id'       => "{$prefix}select",
        'type'     => 'select',
        // Array of 'value' => 'Label' pairs for select box
        'options'  => array(
            'standard' => __( 'Standard', 'rwmb' ),
            'aside'    => __( 'Aside',    'rwmb' ),
            'gallery'  => __( 'Gallery',  'rwmb' ),
            'image'    => __( 'image',    'rwmb' ),
            'aside'    => __( 'Aside',    'rwmb' ),
            'video'    => __( 'Video',    'rwmb' ),
            'status'   => __( 'Status',   'rwmb' ),
            'quote'    => __( 'Quote',    'rwmb' ),
            'link'     => __( 'Link',     'rwmb' ),
            'chat'     => __( 'Chat',     'rwmb' ),
            'audio'    => __( 'Audio',    'rwmb' ),
        ),
        // Select multiple values, optional. Default is false.
        'multiple'    => FALSE,
        'std'         => 'standard',
        'placeholder' => __( 'Select an Item', 'rwmb' ),
    ),

Your array is not written in the correct PHP syntax, so that's most likely the error you're receiving.

There's a nice explanation here in the PHP manual on how to construct arrays .

But you should also consider the add_theme_support() advice suggested in the comments, if you're setting up multiple post formats.

It will give a radio box like this one.

See for example this description.

Its not logical error, its from your syntax. Check your syntax from foreach.
