写了个laravel控制器：

1. <?php
   
2. 
   
3. namespace App\Http\Controllers;
   
4. 
   
5. use Illuminate\Http\Request;
   
6. use App\Models\Post;
   
7. 
   
8. class PostController extends Controller
   
9. {
   
10.     //
    
11.     public function addPost(){
    
12.         return view('add-post');
    
13. 
    
14.     }
    
15.    
    
16.     public function createPost(Request $request){
    
17. 
    
18.         $post=new 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(){
    
27.         $posts= Post::orderBy('id','DESC')->get();
    
28.         return view('posts',compact('posts'));
    
29. 
    
30. }
    
31. public function getPostById($id){
    
32.     $post=Post::where('id',$id)->first();
    
33.     return view('single-post',compact('post'));
    
34. 
    
35. }
    
36. public function deletePost($id){
    
37.     Post::where('id',$id)->delete();
    
38.     return back()->with('post_deleted','Post has been deleted successfully..!');
    
39. 
    
40. }
    
41. public function editPost($id){
    
42.     $post=Post::find($id);
    
43.     return view('edit-post',compact('post'));
    
44. 
    
45. }
    
46. public function updatePost(Request $request){
    
47. 
    
48.     $post=Post::find($request->id);
    
49.     $post->title=$request->title;
    
50.     $post->body=$request->body;
    
51.     $post->save();
    
52.     return back()->with('post_updated','Post has been updated successfully !!');
    
53. 
    
54. }
    
55. 
    
56. }

复制代码

1. Route::get('/', function () {
   
2.     return view('welcome');
   
3. });
   
4. 
   
5. Route::get('/add-post',[PostController::class,'addPost']);
   
6. Route::post('/create-post',[PostController::class,'createPost'])->name('post.create');
   
7. Route::get('/posts',[PostController::class,'getPost']);
   
8. Route::get('/posts/{id}',[PostController::class,'getPostById']);
   
9. Route::get('/delete-post/{id}',[PostController::class,'deletePost']);
   
10. Route::get('/edit-post/{id}',[PostController::class,'editPost']);
    
11. Route::post('/update-post',[PostController::class,'updatePost'])->name('post.update');
