Ability for Form Placeholder to poll

[danharrin]

Discussed in https://github.com/filamentphp/filament/discussions/13459

^{Originally posted by **SimonMacIntyre** July 3, 2024} We make use of Placeholder in forms, to show data related to the entity. For example let's say we have an EditUser page and form. We are using Placeholder as an example while viewing this page, to show some interesting live updating status about some thing based on this user. (Note: This is not suitable to be in a table/relation manager, we make heavy use of that too, but this specifically is a component we want to show right up in the form in a read-only fashion, but have it live-update). Any chance of this being a feature we can add some day? Ideally it would be as simple as... ```php Placeholder::make('status')->poll(5)->... ```

I can make it work just by adding to the TextEntry the following trait:

use CanPollRecords;

And the corresponding polling validator in the blade view:

@if ($pollingInterval = $getPollingInterval()) wire:poll.{{ $pollingInterval }} @endif

However, it seems that Placeholder will be deprecated. Am I right?

Interesting, I'll give that a try, and also take a look at the TextEntry and if that is also pollable or not, thanks for the comment!

It isn't. I mean, this is a code proposal for V4, but I guess I need some guidance before making a PR.
