Meta Box

Hi Toomas,

Unfortunately, it's not possible with the plugin.

Please try this:

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

    var $submitButton = $( '.rwmb-form-submit' ).children( 'button' );
    if ( count > 3 ) {
      $submitButton.prop( 'disabled', true );
    } else {
      $submitButton.prop( 'disabled', false );
    }
  });
});

Hi, I've just checked and can't replicate the bug:

Can you try with no plugins activated and with normal post?

Hi Sergio,

Did you try:

add_action( 'rwmb_field_A_after_save_field', function ( $null, $field, $new, $old, $object_id ) {
    $storage = $field['storage'];
    $storage->update( $object_id, 'field_B', 'new value' );
}, 10, 5 );

This code works only when the field A is put after field B in the meta box, which means field B is already saved.

If field A is before field B, then after we run this code, field B still use value from the submission. In this case, please try this code:

add_action( 'rwmb_field_A_after_save_field', function ( $null, $field, $new, $old, $object_id ) {
    $_POST['field_B'] = 'new value'; // Modify directly submitted value from $_POST.
}, 10, 5 );

Hi Sergio,

I guess you're using another plugin that also enqueues Google Maps. The URL above is different from what Meta Box outputs. If that's correct, it's easy to explain 2 errors in the console: the API key is not provided and the limit exceeds.

Hi Sergo,

Please check the browser dev console to see if there's any message from Google Maps API. Usually, Google will tell you exactly why.

Also check the page source to see if the API key is correct. Maybe other plugins enqueue a different JS file using different a API key.

In the latest version of the MB Frontend Submission plugin, I added some code to disable the submit button when it's already clicked (to prevent duplicated submission). You can take it as a sample and write your own code, like this:

function count_favorites() {...}

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