Setting the default value of a TextInput within a Repeater

Hello, I'm trying to set the default value of TextInput within a Repeater using another field outside this repeater. This is a simplified example of what I'm doing, unfortunately I'm not getting the value of cap field. Any suggestions? public static function form(Form $form): Form { return $form ->schema([ HiddenInput::make('cap'), Repeater::make('numbers') ->schema([ TextInput::make('prefix')->default(fn (Get $get) => $get('../../cap')), // I will add a query that will use the value to retrieve data from DB ]) ]); }

Solution:

Do you want to do this? ```php Forms\Components\Select::make('select') ->options([...

why not mutate before creating instead of hidden? https://filamentphp.com/docs/3.x/panels/resources/creating-records#customizing-data-before-saving

I can do that, but what about the TextInput in the Repeater? What can I do to set is value?

LeandroFerreira•7mo ago

using default, this is correct. Default only works in the create page

Hidden::make('cap')
->default('something'),
Repeater::make('numbers')
    ->schema([
        TextInput::make('prefix')->default(fn (Get $get) => $get('../../cap'))
    ])

Hidden::make('cap')
->default('something'),
Repeater::make('numbers')
    ->schema([
        TextInput::make('prefix')->default(fn (Get $get) => $get('../../cap'))
    ])

Yes, I'm using it in the create page. If I set a default value to the cap field I'm able to get it from prefix field. But what if cap field is set dynamically? Is there a way to set a repeater field value from outside the repeater?

But what if cap field is set dynamically? How are you doing this?

I have a Select field, and in the "afterStateUpdated" I set the "cap" field depending on which option the user has selected in the Select field

LeandroFerreira•7mo ago

afterStateUpdated you want to set all fields in the repeater with this value, right?

spacedevOP•7mo ago

I was thinking of setting the repeater field based on the cap field, I mean within the repeater, using "Get". Anyway, setting the repeater field from the afterStateUpdated of the first Select field or the CAP TexInput would be ok.

we have more or less the same request , except that for me it is in a table and that I want to copy the value of a specific ( let's say Column B) into column A if A is empty so put the value of B as placeholder for example

I think the problem is related to ->default() method This one does not work TextInput::make('prefix')->default(fn (Get $get) => $get('../../cap')) This one does work, I'm able to get cap from outside the repeater Select::make('prefix')->options(function(Get $get){return ['cap' => $get('../../cap')];})

Do you want to do this?

Forms\Components\Select::make('select')
    ->options([
        'option1' => 'Option 1',
        'option2' => 'Option 2',
        'option3' => 'Option 3',
    ])
    ->live()
    ->afterStateUpdated(function (Forms\Components\Select $component, ?string $state) {
        $repeater = $component->getContainer()->getComponent('data.repeater');

        $repeater->state(Arr::map($repeater->getState(), function (array $item) use ($state) {
            $item['prefix'] = $state;

            return $item;
        }));
    }),

Forms\Components\Repeater::make('repeater')
    ->schema([
        Forms\Components\TextInput::make('prefix')
            ->default(fn(Forms\Get $get): ?string => $get('../../select'))
    ]),

Forms\Components\Select::make('select')
    ->options([
        'option1' => 'Option 1',
        'option2' => 'Option 2',
        'option3' => 'Option 3',
    ])
    ->live()
    ->afterStateUpdated(function (Forms\Components\Select $component, ?string $state) {
        $repeater = $component->getContainer()->getComponent('data.repeater');

        $repeater->state(Arr::map($repeater->getState(), function (array $item) use ($state) {
            $item['prefix'] = $state;

            return $item;
        }));
    }),

Forms\Components\Repeater::make('repeater')
    ->schema([
        Forms\Components\TextInput::make('prefix')
            ->default(fn(Forms\Get $get): ?string => $get('../../select'))
    ]),
