Save sleceted value in hidden field

Can you provide the complete CMB2 configuration, something that I could install/activate or load via a php include() ?

From what I recall, hidden fields can be surprisingly tricky. Curious if part of cmb2_sanitize_date_select_field_callback isn’t set quite yet until the 2nd save

    private static $prefix = Copa\PREFIX;

    /**
     * Initiate our hooks.
     */
    public static function init() {

        // Split seaialized String and saves meta for the object.
        add_filter( 'cmb2_override_meta_save', array( MetaSplit::instance(), 'meta_save' ), 100, 3 );

From what I can see, the strtotime() call in cmb2_sanitize_date_select_field_callback() is returning false. It looks like the value is already a UTC timestamp, and wouldn’t need to be re-converted.

Also, based on what I’m experiencing, I’m seeing filled in hidden values after 1 click of update: https://cloudup.com/cobS0CBuOBE

However, I did have to modify slight details of the code since I didn’t have all the classes available, and some minor namespace issues with regards to the prefix. I don’t foresee that drastically changing the results, but it’s something to be aware of.

So I’m wondering if perhaps you’re trying to re-fetch the value before it’s ready?

it’s now working with this address field example and split_values true
But the saved option is not selected

Have you verified you have meta rows for everything in your database? After that, it’d just be a matter of making sure selected() could match up properly.

the serialized values has been overwritten after update post meta

i’ve solved it by saving the additional fields without splitting them

It’s probably not the best solution, but it works me

Sometimes what actually works is better than what is elegant. Good to hear you have something working here.
