Meta Box

Thanks a lot for your feedback. This is an issue with overflow set in the Columns and Tabs extension. I'm fixing them and will release new versions soon.

Ah, when initialize the select2, you can get options via data-options and pass it to the initializer:

var options = $s2.data( 'options' );
$s2.select2( options );

Hi Calpaq, thanks for your feedback, let me check it.

Thanks a lot for your feedback. It's a bug in the plugin and I've just fixed it in the version 1.1.8. Please update.

I made a modification to that script, here is a working version: https://ghostbin.com/paste/tqqof

Hi Brian,

I've just tested the code and it works fine to me. I modified the code a little bit to work for my test (as I don't have your hook, I use the_content, everything else is the same):

Hello,

I answered you on Facebook. I tested and couldn't replicate the bug. Am I missing something?

Hi,

Regarding the first option, to add constraints between fields, I think the only way to do that is with custom JS.

To save sum of some fields, please use rwmb_after_save_post hook. Here you can get fields' values and update the sum to another field:

add_action( 'rwmb_after_save_post', function( $post_id ) {
    $field_1 = get_post_meta( $post_id, 'field_1', true );
    $field_2 = get_post_meta( $post_id, 'field_2', true );
    $field_3 = get_post_meta( $post_id, 'field_3', true );

    $sum = $field_1 + $field_2 + $field_3;
    update_post_meta( $post_id, 'sum', $sum);
} );
