    If you are using the route() helper in your form. You can pass the parameter using it :

    <form action="{{ route('blog.update', ['post' => $post_id]) }}">...</form>

    which is the post is the parameter you name in the route.

    Since you haven’t posted your blade file so here’s the full method:

    in your route:

    Route::put('/blog/{post}/update' , [BlogController::class, 'update']);

    in your blade form make tag like this:

    <form method="post" action="/blog/{{$post->id}}/update">  
//This will show url like /blog/1/update
//For using PUT method add this:
    {{ method_field('PUT') }}
// Do not forget to use @csrf

    Then in your controller update function handle the request and $id like this:

    public function update(Request $request, $id){
    //Find post in your data with help of model
    $post = AppModelsPost::findOrFail($id);
    //validate and update with the post instance of Post class
    //Feel free to add many functions same as of your controller before i'm leaving empty
    $post->update([
        //Add fields for update
    ]);
}
