thanks for taking the time to read this. I've had a look through any similar questions and haven't found a case like this. It's probably something really silly. This is my first time using add_meta_box().

Basically, I'm trying to add a meta box to a custom post type. The field itself is showing, but its right at the top of the page (where errors usually appear)

See screenshot:

Here is the code I'm using for adding the box and the callback. This is inside of class.

public function room_settings_meta_box() {

    add_meta_box(

        'room-settings',

        __( 'Room Settings', 'book-it' ),

        'room_settings_meta_box_callback',

        'rooms'

    );

}



public function room_settings_meta_box_callback( $post ) {



    wp_nonce_field( 'room_settings_nonce', 'room_settings_nonce' );



    $value = get_post_meta( $post->ID, 'room-settings', true );



    echo '<input style="width:100%" id="room-settings" value = "' . esc_attr( $value ) . '" name="room-settings">';

}

I'm also a bit stuck with the get_post_meta($key). Would that be the meta-box ID?

Other examples that I saw all seem to start with an underscore (_META_KEY)

I'll make sure to edit this if I find the solution myself.
