Content submitted fail to be inserted into database

Hello guys please help me out. I have done a page where user can enter data (title,category,image and content) but it does not seems to work and it shows no errors.

Posts Controller

public function store(Request $request) { $this->validate($request,[ 'title'=>'required', 'featured'=>'required|image', 'content'=>'required', 'category_id'=>'required'

    ]);

    $featured = $request->featured;
    $featured_new_name=time().$featured->getClientOriginalName(); /*symfony function to give name for the file uploaded*/
    $featured->move('uploads/posts', $featured_new_name);

    $post = Post::create([
        'title'=>$request->title,
        'content'=>$request->content,
        'featured'=>'uploads/posts'.$featured_new_name,
        'category_id'=>$request->category_id
    ]);
}
