Hello, would it be possible, based on the tuto of Ivan Doric (https://watch-learn.com/video-tutorials/making-websites-with-october-cms-part-10-relations) to show/hide the 'Genre' relation widget, depending on another boolean field ?

I made this working with a standard field with a YAML dependsOn and a hidden value set in filterFields().

With : $fields->types->hidden = true; I receive : Model 'XXX\Models\Event' does not contain a definition for 'types'.

Do you have any ideas for doing this with the widget ? Thanks

Can you share the YAML fields definition file along with the filterFields method?

Here is my code. It works if I put hidden:0 or 1 in the YAML, but not with code.

YAML :

tabs:
  fields:
     categ:
        label: 'Catégorie d''événement'
        type: radio
        tab: Catégorisation
     types:
        label: 'Types d''événement'
        nameFrom: type_nom
        descriptionFrom: description
        type: relation
        tab: Catégorisation

Model :

public function filterFields($fields, $context = null) {
    $bExclus = \DB::table('lb_events_categs')->where('id', $this->categ)->value('categ_exclusive');
    // If exclusive category then hide types
    if ( $bExclus == 1 ) {
        $fields->types->value = 0;
        $fields->types->hidden = true;
        $fields->event_ontv->value = 0;
    }
}

I don't see the dependency between the fields...

the filterFields method will get called when the Form get rendered initially, then when the onRefresh ajax handler gets called (mainly from dependent fields being updated)

filterFields() is correctly called when I make changes, but $fields->types->hidden = true; has no effect, the field "types" is not hide.

You're right ! "dependsOn: categ" is needed in YAML.

I thought the dependsOn was not needed as the code could do it programmatically.

Thanks a lot !

So it's working?

Yes, thanks I added the dependsOn in my YAML.

Regards

In complement, how could I change the switch value with dependOn, based on my query (3rd post) ?

Do I have to understand that I could do it in a query in the YAML ?

https://octobercms.com/docs/backend/forms#field-switch

Yaml :

    event_ontv:
        label: 'Diffusion TV'
        type: switch
        dependsOn: categ
        tab: Catégorisation

Well I just realized that with the following code, the line $fields->event_ontv->hidden = true; is disturbing the dependOn and causing the problem.

If I comment it out, it's working !

    if ( $bExclus == 1 ) {
        $fields->types->value = 0;
        $fields->types->hidden = true;
        $fields->event_ontv->value = 0;
        $fields->event_ontv->hidden = true;
    }

Could this be a problem of October ???
