Php versions – Laravel Blade Displaying Data

I have a weird problem with the syntax of laravel (version 7) {{ }}, where I use PHP syntax like that:

<?php echo $thread->lastReply->user->name; ?>

I get my user displayed but with the blade syntax :

{{$thread->lastReply->user->name}}

I got this error:

ErrorException
Trying to get property ‘user’ of non-object

where could the problem come from?

the method lastReplay in thread is like this:

         public function getLastReplyAttribute()
            {
                $lastReplay = $this->replies->last();
                dd($lastReplay);
                return $lastReplay;
            }

and with dump :

    Is your query returning array or object? If you dump it out, you might find that it’s an array and all you need is an array access ([]) instead of an object access (->).

    it’s mean $thread->lastReply is not an object or usually it’s null. to handle you can use condition example:

    {{$thread->lastReply ? $thread->lastReply->user->name : 'no last reply user'}}

    or

    {{$thread->lastReply->user->name ?? 'no last reply user'}}

    you problem come from ->lastReply. Maybe some users dont have a lastReply ?

    Try the following:

       {{  optional($thread->lastReply, function ($lastReply)
            {
                return $lastReply->user->name;
            });
    }}

    ErrorException
Trying to get property 'user' of non-object

    This error mean either lastReply is returning null or its array

    {{$thread->lastReply->user->name}}

    In this syntax you need to check some data before adding relationships

    1. dump if lastReply is returning data

      {{dd($thread->lastReply)}}

    2. user should exists in model and have right foreign key in relationship.Also it should not be null that you can also check by following code

      {{dd($thread->lastReply->user)}}

    If both dumps returning data then it means lastReply or user is returning array. So you need to use array [] syntax to get data.
    You can also use {!! !!} to print data to escape content
