Làm Thế Nào để Chuyển đổi Bộ Sưu Tập Sang JSON Trong Laravel?

Hướng dẫn này tập trung vào cách chuyển đổi bộ sưu tập sang json trong laravel. Bài đăng này sẽ cung cấp cho bạn một ví dụ đơn giản về đối tượng chuyển đổi laravel thành json. 

Bạn có thể sử dụng ví dụ này với phiên bản laravel 6, laravel 7, laravel 8 và laravel 9.

Đôi khi, chúng tôi đang lấy dữ liệu từ cơ sở dữ liệu và bạn cần chuyển đổi dữ liệu hùng hồn thành JSON thì bạn sẽ thực hiện việc này như thế nào? đừng lo lắng, có nhiều cách để chuyển đổi bộ sưu tập sang JSON trong laravel. chúng ta sẽ sử dụng phương thức toJson () và json_encode () để chuyển mảng đối tượng thành JSON trong laravel.

vì vậy chúng ta hãy xem từng ví dụ dưới đây:

Ví dụ 1: get () với toJson ()

PostController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Post;
  
class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = Post::select("id", "title", "body")
                        ->latest()
                        ->get()
                        ->toJson();
  
        dd($posts);
    }
}

Đầu ra:

[
   {
      "id":40,
      "title":"Post title 1",
      "body":"Post body"
   },
   {
      "id":39,
      "title":"Post title 2",
      "body":"Post body"
   },
   {
      "id":38,
      "title":"Post title 3",
      "body":"Post body"
   }
]

Ví dụ 2: find () với toJson ()

PostController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Post;
  
class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $post = Post::find(40)->toJson();
  
        dd($post);
    }
}

Đầu ra:

{
   "id":40,
   "title":"Post title 1",
   "slug":null,
   "body":"Post body",
   "created_at":"2022-08-05",
   "updated_at":"2022-08-05T13:21:10.000000Z",
   "status":1
}

Ví dụ 3: json_encode ()

PostController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Post;
  
class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = Post::select("id", "title", "body")
                        ->latest()
                        ->take(5)
                        ->get();
  
        $posts = json_encode($posts);
  
        dd($posts);
    }
}

Đầu ra:

[
   {
      "id":40,
      "title":"Post title 1",
      "body":"Post body"
   },
   {
      "id":39,
      "title":"Post title 2",
      "body":"Post body"
   },
   {
      "id":38,
      "title":"Post title 3",
      "body":"Post body"
   }
]

Ví dụ 4: Bộ sưu tập tùy chỉnh sử dụng toJson ()

PostController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = collect([
                ['id' => 1, 'title' => 'Title One', 'body' => 'Body One'],
                ['id' => 2, 'title' => 'Title Two', 'body' => 'Body Two'],
        ]);
  
        $posts = $posts->toJson();
  
        dd($posts);
    }
}

Đầu ra:

[
   {
      "id":1,
      "title":"Title One",
      "body":"Body One"
   },
   {
      "id":2,
      "title":"Title Two",
      "body":"Body Two"
   }
]

Ví dụ 5: Phản hồi JSON

PostController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Post;
  
class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
  
        $posts = Post::select("id", "title", "body")
                        ->latest()
                        ->get();
  
        return response()->json(['posts' => $posts]);
    }
}

Đầu ra:

{"posts":[{"id":40,"title":"Post title 1","body":"Post body"},{"id":39,"title":"Post title 2","body":"Post body"},{"id":38,"title":"Post title 3","body":"Post body"},{"id":37,"title":"Post title 4","body":"Post body"},{"id":36,"title":"Post title 5","body":"Post body"}]}

Tôi hy vọng nó có thể giúp bạn...

Php how to delete multiple rows through checkbox using ajax in laravel

First thing, we will need a table and i am creating products table for this example. So run the following query to create table.

CREATE TABLE `products` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 `description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
 `updated_at` datetime DEFAULT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Next, we will need to insert some dummy records in this table that will be deleted.

INSERT INTO `products` (`name`, `description`) VALUES

('Test product 1', 'Product description example1'),

('Test product 2', 'Product description example2'),

('Test product 3', 'Product description example3'),

('Test product 4', 'Product description example4'),

('Test product 5', 'Product description example5');

Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = [
        'name','description'
    ];
}

Step 2: Create Route

Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.

routes/web.php

Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);
