how to stop laravel from getting error if table is null

Question

i want my code to keep working if the table return null

i tried using if(empty) bla bla bla, but is not seem to be the problem

the problem is laravel don't let me call function on null

@php($article = article::find($id)->get())

error : "Call to a member function get() on null"

Your problem is that article::find($id) returns null, yes? — Mateus Junges

remove the ->get(), it does not make sense there, find() will retrive one model or null. — porloscerros Ψ

You don't need get() on find() as other users say..but if it returns null you can assign any value to your $article using nullcoalesce operator ??. $article = article::find($id) ?? [] if article db returns null $article will be assign to empty array() — danish-khan-I

If aritcle::find($id) returns null, it should solve the problem:

@if($article = article::find($id) != null)
    // If the aricle::find($id) returns anything but null, this block will be reached.
@endif

I think that is better to you to send the data to the view from the controller, instead of using blade directives to fetch data.

something like this:

//Within some controller:
public function show($id)
{
    $article = article::find($id);
    return view('your-view')->with($article);
}

Then you can check if $article is null using blade:

@if(empty($article))
    // The article is empty
@endif

Using ->get() after find() is unnecessary. find() automatically returns the model that matches the primary key provided. You will get errors if you attempt to access $article after find() fails, but it will stop you from getting the error you posted.
