Meta Box

Hi Maxell,

1. The empty option was created for select2 library and is required for the placeholder. Are you using simple select field?

2. Probably check if it's empty is a better way:

$meta = rwmb_meta( 'field_id' );
if ( ! empty( $meta ) ) {
    // Output something
}

I mean in previous reply the validation works only with non-cloneable fields :(. I think in this case you can use custom attributes for phone fields ("pattern" to be exact). For more info, please read this docs:

https://metabox.io/docs/custom-attributes-for-inputs/

Here is the info for HTML pattern attribute:

Thank you very much for the fix. It's added to the plugin here: https://github.com/rilwis/meta-box/commit/fdcbb4ffa7f50182e51c060de54b96d540593b48

Can you please post your code?

Hi @karissademi,

You can use the extensions in your products, both free and commercial. However, you can't just publish them on Github. It's more ethical than licensing.

Hi @Joe,

I think the best way is using code to register post types and meta boxes. Then you can use a version control system like Git to manage your code and deploy to your server. It's much easier and saves you a lot of time if you want to manage multiple websites (even not in a multisite network).

In case of multisite network, I think you can make a must-use plugin to register post types and meta boxes. That way you don't need to activate on all sites in the network.

I think the builder is not very useful here as it requires user input, meaning you have to click-type-click many times to add meta boxes for sites (even with import/export feature). Even though, it's useful if you want to add "extra" meta box for a specific site.

Hi @chillifish, is there any JavaScript error in the console?

Could you please try the latest version of Meta Box on Github? I've just tested the Group extension with 1 file_advanced field (max_file_uploads = 1) and it looks fine to me.
