Dispatching an event from an Action

Hi, should i dispatch an event from an action like this?

Action::make('prova')
  ->action(function () {
      $this->dispatch('prova', ['prova']);
  })

Action::make('prova')
  ->action(function () {
      $this->dispatch('prova', ['prova']);
  })

->dispatch('prova', ['prova']) doesn't work

@teodino93 What is the issue exactly? What's not working?

Actions aren’t livewire components. Maybe

->action(function($livewire) {
    $livewire->dispatch(…);
})

->action(function($livewire) {
    $livewire->dispatch(…);
})

Also in lw3 dispatch events don’t use the array syntax for data. It should be named properties.

If I write

Action::make('prova')->dispatch('prova')

Action::make('prova')->dispatch('prova')

Nothing happens, i have to do like the original post to dispatch an event... I don't know if it's an error or it's correct to do like this.

Have you tried the suggestion from awcodes? 👆

The code that i wrote on the original post works, I just wanted to be sure that should be the correct way to dispatch an event, since there is also a dispatch method.

@awcodes , Sorry for tagging you, but do you know how we can dispatch events using the ->dispatch() method?

awcodes•16mo ago

Looking at the code it should work like you're thinking. Maybe it's a conflict in this case with the name of that action being the same as the event that is being dispatched. It might be trying to call itself.

I've tried with different names

#[On('custom-event')]
public function getCustomActionEvent()
{
    dd('custom action triggered');
}

//works
Action::make('custom_action1')
    ->action(fn () => $this->dispatch('custom-event')),

// does not work
Action::make('custom_action2')
    ->action(null)
    ->dispatch('custom-event')

#[On('custom-event')]
public function getCustomActionEvent()
{
    dd('custom action triggered');
}

//works
Action::make('custom_action1')
    ->action(fn () => $this->dispatch('custom-event')),

// does not work
Action::make('custom_action2')
    ->action(null)
    ->dispatch('custom-event')

With a null action, nothing happens on click anyway. Might have to ask Dan.

LeandroFerreira•16mo ago

yep, but without ->action(), ->action(null) this doesn't work

awcodes•16mo ago

Could even be a situation where using dispatch is only meant to be used internally in action callbacks since it is probably not part of the caching that happens with actions.

LeandroFerreira•16mo ago

hum, ok I don't think it's an issue, but I didn't find a way to execute this. Maybe we can check with Dan on how we can use this. Thank you for your support!

teodino93OP•16mo ago

Ok so we stick to action for now, thank you for the support!

im following this thread too, on the surface it seems like action's dispatch() method doesn't work while livewire's does
