Form ->live() Not Working

HI Again, I have a field that the user needs to enter an increase value, I want this value to save on blur. I believe after reading the docs ->live() will do the job. I have the below code and it doesn't save to the Data Base on Blur but the afterStateUpdated() function does work? Am I missing something obvious here??

Forms\Components\TextInput::make('increase_percent')->label('% Increase') 
                                ->numeric()
                                ->inputMode('decimal')
                                ->live(onBlur: true)
                                ->afterStateUpdated(function (?string $state, ?string $old) {
                                    Notification::make()
                                            ->title('Price Increase Adjusted From ' . $old . ' to' . $state)
                                            ->success()
                                            ->send();
                                })
                            ]),

Forms\Components\TextInput::make('increase_percent')->label('% Increase') 
                                ->numeric()
                                ->inputMode('decimal')
                                ->live(onBlur: true)
                                ->afterStateUpdated(function (?string $state, ?string $old) {
                                    Notification::make()
                                            ->title('Price Increase Adjusted From ' . $old . ' to' . $state)
                                            ->success()
                                            ->send();
                                })
                            ]),

If you are using only the form builder, you should do this https://filamentphp.com/docs/3.x/forms/adding-a-form-to-a-livewire-component/

Thank you but I am using the full filament package, do I still need to add a form to a component?

LeandroFerreira•10mo ago

Try without ->numeric()

MazeEzamOP•10mo ago

I removed

->numeric

->numeric

and also

->inputMode()

->inputMode()

but it still doesn't persist to the database on blur focus. The

afterStateUpdated()

afterStateUpdated()

still works as it should though.

LeandroFerreira•10mo ago

Is it sending the notification after state updated?

MazeEzamOP•10mo ago

Yes it is, just not updating the DB.

LeandroFerreira•10mo ago

Actually, live is working. If you want to save the record afterStateUpdated, you should do $livewire->save() when you are editing the record, and $livewire->create() when you are creating the record

MazeEzamOP•10mo ago

Ok, so what is the point of the

->live()

->live()

function if it doesn't actually do anything? I would have thought this would take care of the Livewire Create and Save etc. If I remove

->live()

->live()

afterStateUpdated still fires, so I'm not sure of the use case here? The Documentation says

->live()

->live()

should trigger the form to re render, is this not the case?

I did, specifically "Reactive fields on blur" My understanding is that adding

->live()

->live()

to a form component would update the DB when the value is changed and the user navigates away from the field? I have to missing something very obvious here......

LeandroFerreira•10mo ago

No, live won't save the field on the DB

MazeEzamOP•10mo ago

Ok thanks, I have misunderstood this completely then. Using your suggestion above

$livewire->save()

$livewire->save()

I tried calling this in the

afterStateUpdated()

afterStateUpdated()

but threw and error "undefined variable $livewire" guessing I need to import a class for livewire?

LeandroFerreira•10mo ago

Did you inject it? https://filamentphp.com/docs/3.x/forms/advanced/#injecting-the-current-livewire-component-instance

Thanks mate, this is now working as I need. This is the code I went with.

->afterStateUpdated(function (Livewire $livewire,?string $state, ?string $old) {
                                    
                                    if ($old == null){
                                        $old = '0.00';
                                        return $old;
                                    }
                                    Notification::make()
                                            ->title('Price Increase Adjusted From ' . $old . '%' . ' to' . ' ' . $state . '%')
                                            ->success()
                                            ->send();

                                            $livewire->save();
                                })

->afterStateUpdated(function (Livewire $livewire,?string $state, ?string $old) {
                                    
                                    if ($old == null){
                                        $old = '0.00';
                                        return $old;
                                    }
                                    Notification::make()
                                            ->title('Price Increase Adjusted From ' . $old . '%' . ' to' . ' ' . $state . '%')
                                            ->success()
                                            ->send();

                                            $livewire->save();
                                })
