Sometimes you might get an undefined variable error in your Laravel 9 project, especially when you try to use it in a view file from a controller. There might be a few possible solutions.

Before we continue to coding examples, the error might just be caused by a spelling mistake.

So, first point:

Make sure that the spelling of the variable is the same in your controller and view. 

Now, lets use the code snippet below as an example:

public function index()
{   
  $title = "Wecode101";
  return view ('pages.index');
}

To pass variable to view, don't do this:

public function index()
{   
  $title = "Wecode101";
  return view ('pages.index', $title);
}

Do this:

public function index()
{   
  $title = "Wecode101";
  return view ('pages.index', compact('title'));
}

Or this:

public function index()
{   
  $title = "Wecode101";
  return view ('pages.index', ['posts' => $posts]);
}
