11.     public function addPost(){
    
12.         return view('add-post');

19.         $post->title=$request->title;
    
20.         $post->body=$request->body;
    
21.         $post->save();
    
22.         return back()->with('post_created','Post has been created successfully !!');
    
23. 
    
24.     }
    
25. 
    
26.     public function getPost(){

30. }
    
31. public function getPostById($id){

33.     return view('single-post',compact('post'));

38.     return back()->with('post_deleted','Post has been deleted successfully..!');
    
39.
