ErrorException: Creating default object from empty value

`AdminController.php`

public function update(Request $r, $post_id) {
    $post = Post::find($post_id);

    $post->post_title = $r->post_title;
    $post->post_image = $r->post_image;
    $post->post_details = $r->post_details;
    $post->post_rating = $r->post_rating;
    $post->id = $r->id;

Blade File

<div class="edit-post-content">

    <form action="{{ route('post.update',$list->post_id) }}" method="POST">
        @csrf
        @method('PUT')

        <input type="hidden" name="id" value="{{$list->id}}">
        <input type="hidden" name="post_rating" value="{{$list->post_rating}}">
        <div class="mb-3">
            Edit Title: <input class="form-control" name="post_title" type="text" id="exampleFormControlInput1" value="{{$list->post_title}}" aria-label="default input example">
        </div>
        <div class="mb-3">
            Edit Description:
            <textarea class="form-control" id="exampleFormControlTextarea1"  name="post_details"  rows="3">
                {{ $list->post_details }}
            </textarea>
        </div>
        <div>
            <img src="{{asset('images/'.trim($list->post_image))}}" alt="" width="120px;">
            Edit Photos:
            <input id="formFileMultiple" class="form-control form-control-lg" name="post_image" type="file" value="{{ $list->post_image }}" multiple>
        </div>
        <button type="submit" class="btn btn-primary">Save Changes</button>
    </form>

</div>

Could someone help me, please?

Welcome to SO ... find can return null, you need to check for that before using what is returned from find as an object — lagbox

There is a chance that the model doesn't exist. You can add a check for this in your controller as follows:

public function update(Request $r, $post_id) {
    $post = Post::find($post_id);
    if (!$post) {
        // You can add code to handle the case when the model isn't found like displaying an error message
        return back();
    }

    $post->post_title = $r->post_title;
    $post->post_image = $r->post_image;
    $post->post_details = $r->post_details;
    $post->post_rating = $r->post_rating;
    $post->id = $r->id;
    
    $post->save();

    return back();
}
