Meta Box

Hey Kasia, no problem at all. I'm glad you figured it out!

If you need any help, please let me know.

I understand.

There's a technical difficulty. The select2, which is the library used for taxonomy field, doesn't support preserving selected order. I'm trying some workarounds posted on that issue to see if I can make it work in WordPress's case.

Hi,

There are several things in this case:

1. I see you create 2 groups: 1 group for categories A & B, 1 group for categories C & D. And you put the conditions in each fields of the groups. That's not good for performance because the plugin has to process all fields. Why don't we put the conditions for the groups only? So we need only 2 conditions instead of 10?

2. The value for the category select actually is the category ID, so we have to use IDs instead of category slug or name.

3. The category select has a field type checkbox_tree, which means its value is an array. We can't use operator = in this case. Instead, use contains.

I have adapted your code and made a fix here (please change the categories' IDs to match your case):

Here is my test:

Yes, that should work. There's no difference where we put the code. It's just the code :D.

Hello,

Can you share the code to register meta boxes? I guess there're some things missed there.

Unfortunately, there's no way to create private composer packages that are publicly accessible :(.

I've tried packagist.com and composer satis, but they work only if you have access to private repos already. So they work for us as an internal team, but not for public.

Hi,

The problem with this method is the translation files are not loaded from translate.wordpress.org. It works only with local translation files which are included directly inside the plugin. The translation from translate.wordpress.org is preferred since it allows users to contribute easily and distribute more reliably. Besides, it has a higher priority, meaning if a language is available on both translate.wordpress.org and inside plugin, the file from translate.wordpress.org is loaded.

For example, this is the translation page for Meta Box in Vietnamese:

https://translate.wordpress.org/locale/vi/default/wp-plugins/meta-box

Translation files from translate.wordpress.org are stored in wp-content/languages/plugins/meta-box/ and are regularly updated when new translations available.

Ideally, I'd love to remove the languages file from the plugin, so only translations from translate.wordpress.org are used. At the moment, some languages are not available on translate.wordpress.org yet.

In your case, in order to make it work with your theme without modifying the plugin, you can add this line directly into your theme:

load_textdomain( 'meta-box', plugin_basename( RWMB_DIR ) . '/languages/meta-box-'.get_locale().'.mo' );

It works the same way 😉

Hi,

I think your jQuery selector is too generic. It targets .grpsports, which is all element having that class. In the JS code, there's a parameter element that you should use to get its parent group element, and add the error message to that group only. Please try this:

jQuery('#post').validate({
    errorPlacement: function(error, element) {
        var $group = element.closest('.grpsports');
        if ($group.length) {
            error.insertAfter($group.find('input:text:last'));
        }
    }
});

To target the form in both admin/frontend, you can use multiple selector like jQuery('#post, .rwmb-form').
