Livewire: protected props get null value after submit or any action

[devscript-abdo]

Description

if I declare a protected var like :: protected $categories;

protected $categories;
public function mount(Category $categorie )
{
$this->categories= $categorie;

}

in render method $this->categories still has data
public function render()
{

    return view('livewire.product.products', [
         'categories'=>   $this->categories->all(),

    ]);
}

when I call {{dd($categories)}} in blade view('livewire.product.products') … Data it's still no problem here 💯

but when I call a method from submit Form example :

and inside submit() function I need $this->categories example ::

public function submit()
{
dd($this->categories ); return null
}
$this->categories return null after any action !!!

Exact steps to reproduce

solution I use is inject Model in function again but i don't like it !!!
public function submit(Category $categorie)
{
dd($categorie->all() ); return data
}

Context

• Livewire version: [e.g. 2.2.3]
• Laravel version: [e.g. 8.3.1]
• Alpine version: [e.g. 2.3.0]
• Browser: [e.g. Chrome, Safari]

That is how it works, only public properties are accessible between requests. So you have to make $categories public if you want it accessible in your submit method.

See here in the docs https://laravel-livewire.com/docs/2.x/properties#important-notes

protected and private properties DO NOT persist between Livewire updates. In general, you should avoid using them for storing state.

Hope this helps!
