OCTOBERCMS形式及模型

Question

我在OctoberCms一个新手，我没有太多的知识Laravel也。虽然自学习我面对这个样子，如果存在记录查询我需要读取数据库并查找匹配，我真的很迷惑是一个选择的请求。

这是我在form.htm形式，我设计我的表。

use Drufal\DynamicContentManager\Models\MembersVerification;
==
   <form data-request="onSend" accept-charset="UTF8" enctype="multipart/form-data">
        <div class="form-group">
          <label>First Name:</label>
          <input type="text" class="form-control" name="first_name" required>
        </div>
        <div class="form-group">
          <label>Middle Name:</label>
          <input type="text" class="form-control" name="middle_name">
        </div>
        <div class="form-group">
          <label>Last Name:</label>
          <input type="text" class="form-control" name="last_name" required>
        </div>
        <div class="form-group">
          <button type="submit" class="btn btn-primary" >Submit</button>
        </div>
      </form>

这我的模型

<?php namespace Drufal\DynamicContentManager\Models;

use Model;
use Input;

/**
 * Model
 */
class MembersVerification extends Model
{
use \October\Rain\Database\Traits\Validation;

/*
 * Disable timestamps by default.
 * Remove this line if timestamps are defined in the database table.
 */
public $timestamps = false;

/**
 * @var array Validation rules
 */
public $rules = [
];

/**
 * @var string The database table used by the model.
 */
public $table = 'drufal_dynamiccontentmanager_members';

   public function onSend(){
        $fn = Input::get('first_name');
        $mn = Input::get('middle_name');
        $ln = Input::get('last_name');
      $membertbl=$table::where('first_name', '=', $fn)->first();
        if ($membertbl === null) {
           echo"
                <script>
                alert('Successfully');
                </script>

                ";
        }else{
            echo"NO RESULT";
            }     
    }
}

帮助新手请。

我想你错过了DB ::您的数据库请求：

$users = Db::table('users')->where('votes', 100)->first();
