如何在Laravel中将新用户插入MySQL表？

---

您可以通过以下几种方式插入新用户，如下例所示。要从Laravel插入新用户，您可以使用artisan seeder。为此，首先使用以下命令创建一个seeder：

php artisan make:seeder UserSeeder

命令执行后，您将在database/seeders目录下得到**UserSeeder.php**文件。将代码添加到seeder文件中，以在users表中添加用户记录，如下所示。

示例1

<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Str;

class UserSeeder extends Seeder {
   /**
   * Run the database seeds.
   *
   * @return void
   */

   public function run(){
      foreach(range(1,1000) as $index) {
         DB::table('users')->insert([
            'name'=>Str::random(10),
            'email'=>Str::random(10).'@gmail.com',
            'password'=>Str::random(10)
         ]);
      }
   }
}

现在运行命令来执行seeder文件：

php artisan db:seed --class=UserSeeder

命令执行后，您应该能够在users表中看到数据。

示例2

使用DB facade的**insert()**方法：

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class UserController extends Controller {
   public function index() {
      $user = DB::table('users')->insert([
         'name' => 'Vishal Khanna',
         'email' => '[email protected]',
         'password' => 'vishal123',
      ]);
      if ($user) {
         echo "User inserted successfully!";
      } else {
         echo "Error while inserting user details";
      }
   }
}

DB facade的**insert()**方法用于将记录插入users表。

输出

上述代码的输出为：

User inserted successfully!

示例3

使用Laravel eloquent模型的**create()**方法：

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;

class UserController extends Controller {
   public function index() {
      $user = User::create(['name'=>'Ashish Sehgal', 'email'=>'[email protected]', 'password'=>'ashish123']);
      if ($user) {
         echo "User inserted successfully!";
      } else {
         echo "Error while inserting user details";
      }
   }
}

输出

上述代码的输出为：

User inserted successfully!

示例4

使用Laravel eloquent通过创建用户对象并使用**save()**方法插入users表，如下所示：

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;

class UserController extends Controller {
   public function index() {
      $user = new User();
      $user->name = 'Kiya Singh';
      $user->email ='[email protected]';
      $user->password='kiya123';
      $user->save();
      if ($user) {
         echo "User inserted successfully!";
      } else {
         echo "Error while inserting user details";
      }
   }
}

输出

上述代码的输出如下：

User inserted successfully!
