Custom "Save" button to create or save a form

I'm trying to add a custom "Save" button (i.e. action) to a form.

...
use Filament\Forms\Components\Actions\Action;
...

public static function form(Form $form): Form
{
    return $form
        ->schema([
            Section::make('Parameters')
                ->schema(...)
                ->footerActions([
                    Action::make('save')
                        ->label('Save')
                        ->action('save'),
                    ]),
                ...

...
use Filament\Forms\Components\Actions\Action;
...

public static function form(Form $form): Form
{
    return $form
        ->schema([
            Section::make('Parameters')
                ->schema(...)
                ->footerActions([
                    Action::make('save')
                        ->label('Save')
                        ->action('save'),
                    ]),
                ...

If I pass the string 'save' to the ->action() method, it successfully saves changes to any form fields if I'm Editing a record and click the "Save" button. However, if I'm Creating a record and click the "Save" button, I see an error: Unable to call component method. Public method [save] not found on component. If I pass the string 'create' to the ->action() method, it successfully saves the values in the form fields if I'm Creating a record and click the "Save" button. However, if I'm Editing a record and click the "Save" button, I see an error: Unable to call component method. Public method [create] not found on component . I tried passing a closure to the ->action() method to return the appropriate string depending on the type of form, but this causes nothing to happen on clicking the "Save" button... ->action(fn ($operation) => ($operation === 'edit') ? 'save' : 'create') I'm guessing that ultimately my closure needs to return an object, rather than a string, but I'm not clear what that object should be. Any pointers would be gratefully received.

Solution:

You could create a trait with a custom method and use this in Create/Edit page.. ```php public function createOrSave(): void {...

You could create a trait with a custom method and use this in Create/Edit page..

public function createOrSave(): void
{
    match (class_basename($this)) {
        default => null,
        'CreatePage' => $this->create(),
        'EditPage' => $this->save()
    };
}

public function createOrSave(): void
{
    match (class_basename($this)) {
        default => null,
        'CreatePage' => $this->create(),
        'EditPage' => $this->save()
    };
}

Action::make('save')->action('createOrSave')

Action::make('save')->action('createOrSave')

A big thank you for your suggestion @Leandro Ferreira - that's a nice way of doing it and I now have a better understanding of which methods the 'save' and 'create' strings were referring to. I slightly adapted the custom method you suggested to fit with my implementation (as I have an additional class named BaseCreateRecord which descends from CreateRecord and introduces some common functionality to child classes)...

trait CanCreateOrSave {
    /**
     * Calls the appropriate method to either create a new record, 
     * or save changes to an existing record. 
     * This method name can be passed to an the ->action() method 
     * of an Action component.
    */
    public function createOrSave(): void
    {
        if (is_subclass_of($this, \Filament\Resources\Pages\CreateRecord::class)) {
            $this->create();
        } else if (is_subclass_of($this, \Filament\Resources\Pages\EditRecord::class)) {
            $this->save();
        }
    }
}

trait CanCreateOrSave {
    /**
     * Calls the appropriate method to either create a new record, 
     * or save changes to an existing record. 
     * This method name can be passed to an the ->action() method 
     * of an Action component.
    */
    public function createOrSave(): void
    {
        if (is_subclass_of($this, \Filament\Resources\Pages\CreateRecord::class)) {
            $this->create();
        } else if (is_subclass_of($this, \Filament\Resources\Pages\EditRecord::class)) {
            $this->save();
        }
    }
}
