FileUpload file validation after upload, before submit

Is it possible to validate a FileUpload field before submit? I can access the uploaded file using

afterStateUpdated

afterStateUpdated

and similar functions, but is there any function other than

rules

rules

rules

rules that has access to

$fail

$fail

$fail

$fail? I tried throwing ValidationError, etc but those didn't seem to work.

Solution

Thanks!

I may have gotten it working with

->afterStateUpdated(function (\Livewire\Component $livewire, Forms\Components\FileUpload $component) 
    $livewire->validateOnly($component->getStatePath())
})

->afterStateUpdated(function (\Livewire\Component $livewire, Forms\Components\FileUpload $component) 
    $livewire->validateOnly($component->getStatePath())
})

->afterStateUpdated(function (\Livewire\Component $livewire, Forms\Components\FileUpload $component) 
    $livewire->validateOnly($component->getStatePath())
})

->afterStateUpdated(function (\Livewire\Component $livewire, Forms\Components\FileUpload $component) 
    $livewire->validateOnly($component->getStatePath())
})
