namespace app\index\model;

use think\Model;

class User extends Model
{
    // 定义主键和表名
    protected $pk = &#39;id&#39;;
    protected $table = &#39;user&#39;;
}

User The database table structure corresponding to the model is as follows:

CREATE TABLE `user` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(50) NOT NULL DEFAULT '',
  `password` varchar(50) NOT NULL DEFAULT '',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

public function deleteUsers($ids)
{
    $result = $this->where('id', 'in', $ids)->delete();
    return $result;
}

In the above code, the first parameter of the where method is the field name, and the first parameter is the field name. The two parameters are operators, and the third parameter is the value that needs to be matched. The in operator means to find the value of the id field in the $ids array. The data. Finally, call the delete method to delete the matching data.

Test to delete multiple data

Write test code in the controller:

public function deleteUsers()
{
    $ids = [1, 2, 3];
    $userModel = new User();
    $result = $userModel->deleteUsers($ids);
    if ($result) {
        return '删除成功';
    } else {
        return '删除失败';
    }
}

In the above code, we call the deleteUsers method to delete the ID 1 ,2,3 user data. Finally, the corresponding information is returned according to the deletion result.
