Use $get to find repeater value

Hello - I am using a repeater on a form. Within the repeater, I want the user to select an option from a list. If a new section is added to the repeater, I do not want the category that has already been selected above to be an option. I am trying to use $get to find the repeater but nothing seems to work. I've tried $get('selections') and $get('../selections') but nothing has worked. What am I missing?

Repeater::make('selections')
                            ->columns(4)
                            ->disableItemMovement()
                            ->maxWidth('max-w-7xl')
                            ->minItems(1)
                            ->createItemButtonLabel('Add Category')
                            ->collapsible()
                            ->reactive()
                            ->schema([
                                Select::make('menu_category')
                                    ->label('Category')
                                    ->required()
                                    ->options(function(callable $get) {
                                        $repeater = $get('../selections');
                                        $idsAlreadyUsed = [];
                                        if(isset($repeater[0])) {
                                            foreach($repeater as $section) {
                                                if(in_array($section['menu_category'], $idsAlreadyUsed) === false) {
                                                    $idsAlreadyUsed[] = $section['menu_category'];
                                                }
                                            }
                                        }
                                        return MenuCategory::whereNotIn('id', $idsAlreadyUsed)->pluck('name', 'id')->toArray();
                                    }),

I found this yesterday. I'm pretty sure I tried getState and got an error. But I'll try it again When I try this:

Repeater::make('selections')
                            ->columns(4)
                            ->disableItemMovement()
                            ->maxWidth('max-w-7xl')
                            ->minItems(1)
                            ->createItemButtonLabel('Add Category')
                            ->collapsible()
                            ->reactive()
                            ->schema([
                                Select::make('menu_category')
                                    ->label('Category')
                                    ->required()
                                    ->reactive()
                                    ->options(function(RelationManager $livewire) {
                                        Log::debug($livewire->getState());
                                        return MenuCategory::pluck('name', 'id')->toArray();
                                    }),

Repeater::make('selections')
                            ->columns(4)
                            ->disableItemMovement()
                            ->maxWidth('max-w-7xl')
                            ->minItems(1)
                            ->createItemButtonLabel('Add Category')
                            ->collapsible()
                            ->reactive()
                            ->schema([
                                Select::make('menu_category')
                                    ->label('Category')
                                    ->required()
                                    ->reactive()
                                    ->options(function(RelationManager $livewire) {
                                        Log::debug($livewire->getState());
                                        return MenuCategory::pluck('name', 'id')->toArray();
                                    }),

I get an error saying Method App\Filament\Resources\OrderResource\RelationManagers\SelectionsRelationManager::getState does not exist.

Hello! Sorry for digging up the thread, did you find a way to make it work ? @bwurtz999

bwurtz999OP•2y ago

@sparkyyy_ yes I did. I wasn't going up enough levels $get('../../selections') solved it for me

Spârky•2y ago

I'll try this tomorrow! Thanks for the quick response 🙂 Good morning 🙂 I tried to adapt your code to my problem but it seems like the condition

if(isset($repeater[0]))

if(isset($repeater[0]))

is never fulfilled so I still have all the options. Are you sure this is all the code you have?

Dan Harrin•2y ago

0 is not necessarily a repeater index usually they are uuids

Spârky•2y ago

Yes I noticed that, when I var_dump my repeater, I get a uuid but it changes every refresh Any idea?

Dan Harrin•2y ago

Arr::first($repeater) ?

Spârky•2y ago

Ok, I almost made it work Now when I pick an option, this option is not available for other instances but it also removes it from the input 😦 Here is the code :

Forms\Components\Repeater::make('product_menu')
    ->label("Produits du menu")
    ->schema([
        Forms\Components\Select::make('product_id')
            ->label('Produit')
            ->required()
            ->options(function (callable $get){
                $repeater = $get('../../product_menu');
                $idIsAlreadyUsed = [];
                $repeater_uuid = array_key_first($repeater);
                if (isset($repeater[$repeater_uuid])){
                    foreach ($repeater as $section){
                        if (in_array($section['product_id'], $idIsAlreadyUsed) === false){
                            $idIsAlreadyUsed[] = $section['product_id'];
                        }
                    }
                }
                return Product::whereNotIn('id', array_filter($idIsAlreadyUsed, fn ($value) => !is_null($value)))->pluck('name','id')->toArray();
            }),

Forms\Components\Repeater::make('product_menu')
    ->label("Produits du menu")
    ->schema([
        Forms\Components\Select::make('product_id')
            ->label('Produit')
            ->required()
            ->options(function (callable $get){
                $repeater = $get('../../product_menu');
                $idIsAlreadyUsed = [];
                $repeater_uuid = array_key_first($repeater);
                if (isset($repeater[$repeater_uuid])){
                    foreach ($repeater as $section){
                        if (in_array($section['product_id'], $idIsAlreadyUsed) === false){
                            $idIsAlreadyUsed[] = $section['product_id'];
                        }
                    }
                }
                return Product::whereNotIn('id', array_filter($idIsAlreadyUsed, fn ($value) => !is_null($value)))->pluck('name','id')->toArray();
            }),

Dan Harrin•2y ago

you could use $state to get the current value and make sure its present in this set of options

bwurtz999OP•2y ago

@sparkyyy_ I think you're missing something in the if statement. It wasn't in the original I posted in this thread, but here is what I use that now works:

->options(function($livewire, callable $get) {
  $info = $get('../../selections');
  $thisMenuCategory = $get('menu_category');
  $idsAlreadyUsed = [];
  foreach($info as $repeater) {
    if(in_array($repeater['menu_category'], $idsAlreadyUsed) === false
        && $repeater['menu_category'] !== null
        && $repeater['menu_category'] != $thisMenuCategory) {
        $idsAlreadyUsed[] = $repeater['menu_category'];
    }
  }
  return MenuCategory::whereNotIn('id', $idsAlreadyUsed)->pluck('name', 'id')->toArray();
                                    }),

->options(function($livewire, callable $get) {
  $info = $get('../../selections');
  $thisMenuCategory = $get('menu_category');
  $idsAlreadyUsed = [];
  foreach($info as $repeater) {
    if(in_array($repeater['menu_category'], $idsAlreadyUsed) === false
        && $repeater['menu_category'] !== null
        && $repeater['menu_category'] != $thisMenuCategory) {
        $idsAlreadyUsed[] = $repeater['menu_category'];
    }
  }
  return MenuCategory::whereNotIn('id', $idsAlreadyUsed)->pluck('name', 'id')->toArray();
                                    }),

I think because you don't have && $repeater['menu_category'] != $thisMenuCategory is why it keeps being removed

Spârky•2y ago

Oh okay, I tried to do something with the state but couldn't make it work I'll be on a vacation until Monday but I'll keep you updated. Thanks anyway! 🙂 Hello! I hope you are doing well 🙂 Thank you so much, this is exactly what I was looking for and it is working 🥲
