如何在octobercms中显示用户的所有帖子

I am trying to display all posts by a user and have this in my code that works only when a user is signed in and displays all the user's posts.

$id =  Auth::getUser()->id;

    $this['allproducts'] = Advert::where('user_id', $id)->orderby('created_at','desc')->get();

I want to make this visible to all signed in or not. when i logged out and try to access the url, it throws up an error

Trying to get property 'id' of non-object

try using: If there is no authenticated user it gives null and it should not fetch. (If user_id does not remain null on Advert model table)

$id =  Auth::getUser()->id ?? null;
if (Auth::user()){

You should check whether your entries using the command.

It is not clear in this context who you refer to as a User.

If you want to make the posts of 'any user' accessible to 'any other user' then your implementation is not correct.

Auth::getUser() - Retrieves the signed in User from the active session - See here - The error you posted is expected because after sign out, the Auth session is cleared and you cannot access the id property anymore.

You are basically doing $id = null->id;

What you could do is list the registered users and let the site visitor / user decide which user's posts to display.
