Checkbox List, select at least one

Hi, I have a checkbox list where at least one checkbox needs to be selected. I thought it would be easy using the required but it is allowing me to save the form without one checkbox selected The checkboxlist is in a custom livewire component

Forms\Components\CheckboxList::make('users')
  ->bulkToggleable()
  ->options(User::all()->pluck('name', 'name'))
  ->hidden(fn() =>...)
  ->required()

Forms\Components\CheckboxList::make('users')
  ->bulkToggleable()
  ->options(User::all()->pluck('name', 'name'))
  ->hidden(fn() =>...)
  ->required()

I also tried adding

->rules([function()....])

->rules([function()....])

But I cant get this working either. It never even validates the thing

thats because a non checked is also a valid state for it to be required can you add a validation rule min:1 see if that works?

unfortunatly the min method is not present on checkboxlist. Tried the ->rules(['min:1']) but it skips it as well... I have the feeling that it skips the entire rules() method. If i do this:

Forms\Components\CheckboxList::make('users')
  ->required()
  ->bulkToggleable()
  ->rules([
      function () {
          return function (string $attribute, $value, Closure $fail) {
              dd('test if executed');
              if ($value === 'foo') {
                  $fail('The :attribute is invalid.');
              }
          };
      },
  ])
  ->options(User::all()->pluck('name', 'name'))

Forms\Components\CheckboxList::make('users')
  ->required()
  ->bulkToggleable()
  ->rules([
      function () {
          return function (string $attribute, $value, Closure $fail) {
              dd('test if executed');
              if ($value === 'foo') {
                  $fail('The :attribute is invalid.');
              }
          };
      },
  ])
  ->options(User::all()->pluck('name', 'name'))

It skips the check... Which is weird right? It should just dump the string when pressed save Anybody has some insight into these validation rules? I cant get them working 😦

mm can you solve it with a multi select instead of a checkbox list ? 😛

Just validate the array and check for at least one true value. This will get you going: https://stackoverflow.com/questions/45758449/laravel-validate-at-least-one-item-in-a-form-array

Allright thanks, but for this to work I need to be able to execute a rule in the ->rules() method. Somehow I cant even get the function inside rules to work...

Show your code, did you create a separate file or are you using a closure? Did you wrap it in an array? This is what the docs describe: https://filamentphp.com/docs/3.x/forms/validation#custom-rules
