Hello,

I am trying to disable (not hide) a taxonomy option when the file_upload field is empty.

I took a look at the conditional logic plugin https://metabox.io/docs/meta-box-conditional-logic/ but it's not clear to me if this is possible.

I will appreciate any help. Thank you.

Dear woorise,

The plugin is intended to show or hide field or meta box, it cannot disable a field.

Best,

Tan

Thank you for the quick respond.

Is possible to add the "disable" property in the toggle_type option?

If not how can I check if the file_upload is empty or not when the file_upload is change?

I tried the following but it doesn't work properly:
```
  jQuery('.rwmb-file_upload').on( 'change', function() {

    var uploaded = jQuery('.rwmb-media-input').val();

    if ( uploaded ) {
      //code here
    }

  });
```

Dear woorie,

Because toggle_type is affected to whole field/meta box and its container and many fields aren't normal form input field so it isn't possible. Sorry for that.

I see. So I need to do this manual.

Can you please give me some info on what event is triggered when we use the "file_upload" field so I can disable/enable the select option if the user upload a file.

I tried the code above but it doesn’t work properly.

Just to be sure, you want to know when files are added or removed?

@woorise Your solution has a flaw; you check if the result is empty by checking the length. This should work:
```
jQuery('.rwmb-file_upload').on( 'change', function() {
    var uploaded = jQuery('.rwmb-media-input');
    if ( uploaded.length ) {
      //code here
    }
  });
```

I just added a new commit on GitHub. The change event now includes a second argument, which contains all of the hidden inputs. This will allow you to count them to see if any are selected:
```
jQuery('.rwmb-file_upload').on( 'change', function( event, items) {
    if ( items.length ) {
      //code here
    }
  });
```

Thank you for your answer.

I tried the following on a "select_advanced" field but if I first open the dropdown then it doesn't enable the option.
```
jQuery(document).ready(function(){

  jQuery("#status option[value='23']").prop("disabled", true);

  jQuery('.rwmb-file_upload').on( 'change', function( event, items ) {

    if ( items.length ) {
      jQuery("#status option[value='23']").prop("disabled", false);
    }

  });
});
```

Can you post your code so I can experiment with what you are trying to do?
