The second-hand recycling website developed by PHP provides after-sales service evaluation function

With the continuous expansion of the second-hand trading market, the importance of second-hand recycling websites has become increasingly prominent. In order to provide a better user experience, second-hand recycling websites not only need to provide convenient and fast second-hand item transaction services, but also need to provide after-sales service evaluation functions. This article will introduce how to use PHP to develop a second-hand recycling website and add an after-sales service evaluation function.

First of all, we need to build a basic second-hand recycling website. To simplify the development process, we use the PHP framework Laravel to build the website. Create a Laravel project named "Recycle" and create a model named "Item" to represent used items.

The command to create the "Item" model is as follows:

php artisan make:model Item
Copy after login

Next, we need to create a table named "items" in the database to store information about second-hand items. In Laravel, database migration is a way of managing the structure of the database. We create a database migration named "create_items_table" using the following command:

php artisan make:migration create_items_table --create=items
Copy after login

Open the generated migration file and we can define the fields of the "items" table:

use IlluminateSupportFacadesSchema; use IlluminateDatabaseSchemaBlueprint; use IlluminateDatabaseMigrationsMigration; class CreateItemsTable extends Migration { public function up() { Schema::create('items', function (Blueprint $table) { $table->bigIncrements('id'); $table->string('name'); $table->text('description'); // 在此处添加其他字段 $table->timestamps(); }); } public function down() { Schema::dropIfExists('items'); } }
Copy after login

Next, run the following Command to execute database migration:

php artisan migrate
Copy after login

At this point, we have created a simple second-hand recycling website. Now, we need to add the function of after-sales service evaluation.

First, we add a field named "rating" to the "items" table to store users' evaluations of after-sales service. Update the database migration file as follows:

use IlluminateSupportFacadesSchema; use IlluminateDatabaseSchemaBlueprint; use IlluminateDatabaseMigrationsMigration; class CreateItemsTable extends Migration { public function up() { Schema::create('items', function (Blueprint $table) { $table->bigIncrements('id'); $table->string('name'); $table->text('description'); $table->integer('rating')->nullable(); // 添加评价字段 $table->timestamps(); }); } public function down() { Schema::dropIfExists('items'); } }
Copy after login

Next, update the "Item" model and add a "rate()" method to evaluate the after-sales service:

namespace App; use IlluminateDatabaseEloquentModel; class Item extends Model { protected $fillable = ['name', 'description', 'rating']; // 添加评价方法 public function rate($rating) { $this->rating = $rating; $this->save(); } }
Copy after login

Now, we can control Evaluate the after-sales service in the device. Suppose we have a controller named "ItemController" in which the "rate()" method accepts request parameters and saves the rating to the database:

namespace AppHttpControllers; use AppItem; use IlluminateHttpRequest; class ItemController extends Controller { public function rate(Request $request, Item $item) { $item->rate($request->input('rating')); return response()->json(['message' => '评价成功']); } }
Copy after login

Finally, we need to add a rating to the front-end web page box, after the user evaluates the after-sales service, submit the evaluation to the "rate()" method. The following is a simple front-end example:

@csrf
Copy after login

So far, we have successfully implemented a second-hand recycling website developed using PHP and added an after-sales service evaluation function. Users can evaluate the after-sales service on the website and save the evaluation to the database. Through the above sample code, we can use PHP to develop a fully functional second-hand recycling website to provide users with a better user experience.
