Livewire component with custom, dynamic form, struggling with select default values

I have this in my livewire component:

    public function form(Form $form): Form
    {
        return $form->schema($this->getFormFields());
    }

    public function getFormFields()
    {
        if (empty($this->selectedTableHeaders)) return [];
        $arr = [];
        $i = 1;

        foreach ($this->selectedTableHeaders as $key => $mapping) {

            $defaults = $this->fieldColumnMap[$mapping['id']];
            $options = $mapping['header_array'];
   
            $arr[] = Section::make('Selected Header ' . $i)->description($key)->aside()->schema([
                Grid::make()->columns(2)->schema([
                    Select::make($mapping['id'] . '-transaction_date')->label('Transaction Date')->default(array_search($defaults['transaction_date'], $options))->options($options),
                   ...more selects similar to above...
                ]),
            ]);

            $i++;
        }

        return $arr;
    }

    public function form(Form $form): Form
    {
        return $form->schema($this->getFormFields());
    }

    public function getFormFields()
    {
        if (empty($this->selectedTableHeaders)) return [];
        $arr = [];
        $i = 1;

        foreach ($this->selectedTableHeaders as $key => $mapping) {

            $defaults = $this->fieldColumnMap[$mapping['id']];
            $options = $mapping['header_array'];
   
            $arr[] = Section::make('Selected Header ' . $i)->description($key)->aside()->schema([
                Grid::make()->columns(2)->schema([
                    Select::make($mapping['id'] . '-transaction_date')->label('Transaction Date')->default(array_search($defaults['transaction_date'], $options))->options($options),
                   ...more selects similar to above...
                ]),
            ]);

            $i++;
        }

        return $arr;
    }

The above form is generated dynamically based on user selections in step 1 of a wizard. Step 2 is the above code. However, the default value isn't working on the select. I've tried adding $this->form->fill() to my render method, but it's not working. Since I don't know how many forms/fields will exist until the user makes a selection, I can't set the defaults inside of $this->form->fill(). In my blade file I have this:

        @if ($currentStep == 1)
            {{ $this->table }}
        @endif

        @if ($currentStep == 2)
            {{ $this->form }}
        @endif

        @if ($currentStep == 1)
            {{ $this->table }}
        @endif

        @if ($currentStep == 2)
            {{ $this->form }}
        @endif

Any ideas?

Still struggling with this, hoping maybe someone has some ideas. This is the current iteration of the offending code. I just can't seem to set a default value for the select:

 Select::make($mapping['id'] . '-transaction_date')
                            ->label('Transaction Date')
                            ->formatStateUsing(fn () => array_search($defaults['transaction_date'], $outputArr))
                            // ->afterStateUpdated(fn (Select $component) => $component->state(array_search($defaults['transaction_date'], $outputArr)))
                            ->live()
                            ->options($options)
                            ->required(),

 Select::make($mapping['id'] . '-transaction_date')
                            ->label('Transaction Date')
                            ->formatStateUsing(fn () => array_search($defaults['transaction_date'], $outputArr))
                            // ->afterStateUpdated(fn (Select $component) => $component->state(array_search($defaults['transaction_date'], $outputArr)))
                            ->live()
                            ->options($options)
                            ->required(),

I've also tried

 ->afterStateHydrated(fn (Select $component) => $component->state(array_search($defaults['transaction_date'], $options)))

Defaults should be passed through $this->form->fill() I think

LeandroFerreira•4w ago

You should add $this->form->fill() in the mount method and use a statePath. Check the docs https://filamentphp.com/docs/3.x/forms/adding-a-form-to-a-livewire-component/#adding-the-form
