Meta Box

Thanks Long, I couldn't get it working this way, but I found another solution.
Consider it closed.

That's what I did, and yet I get to see the posts of all other values for the taxonomy as well.

The selection: https://share.getcloudapp.com/6qu5jo5z

The result: https://share.getcloudapp.com/d5uvmXPR

For info, as the site in in Dutch language: Geloofsgemeenschap = Location, Nieuwsberichten = Newsitems

Okay, but then I still have to do a calculation in one way or the other. I was hoping that such function would exist somewhere in the toolbox.
I have solved it by using yet another plugin... I was trying to avoid it, but I am not a skilled coder...

Thanks, consider it solved.

I'm running PHP 7.2.

Hi Anh,

To count the number of favorites, I have the following JS:

jQuery(document).ready(function( $ ){
$(document).ready(function () {
  $('.count input').attr('readonly', true);
  $('.radio').change(function () {
    var count=0;
    $('.radio input:checked').each(function(){
      if ($(this).val().replace(/V_/g,'')=="Specialiteit") {
        count += 1;
      }
    });
    $('.count input').val(count);
  });
});
});

That works nicely. (Btw: "Specialiteit" = Specialty, so I'm counting the specialties instead of favorites)

How to add your code there?
I created another JS file with the following code, but the submit button never gets disabled.

$( 'input[type="radio"]' ).on( 'change', function() {
    var $submitButton = $( '.rwmb-form-submit' ).children( 'button' );
    if ( .count() > 3 ) {
        $submitButton.prop( 'disabled', true );
    } else {
        $submitButton.prop( 'disabled', false );
    }
} );

Hi Anh,

I have taken up this idea again to limit the number of favorites.
Currently the number of favorites is counted and that number is shown on screen.

What I want to do next is to dim the Save/Confirm button as long as the counter is higher than the number of allowed favorites.

How can I do that?

So simple... Excellent! Thanks a lot.
