Meta Box

This commit fixes it. Please try again.

Hi @Maxell, I've just pushed a fix for this on Github. Please try it. New version will be released soon.

Hi @brightcreations,

I'm still working on it. I'm having problems with JavaScript :(. It might take some days. I hope I can solve it this week.

Hi @Sinusite,

I think it's not possible for now. Using a raw PHP code requires running eval which is not recommended because of security matter :(.

Can you send me the code to check for you?

Hi Maxell, I guess the bug is from JavaScript. In the version 4.5, WordPress updates its library Underscore from 1.6.0 to 1.8.3. It's a big update and because Meta Box uses Underscore library to render template for media upload, I think the fastest way is updating the Meta Box plugin :(.

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
}
