Question

我有一个类似Activites表的表：

并且我使用此代码将数据从数据库提取到表中在Controller中：

$TableB1 = \DB::table('users')
    ->join('group_user', 'users.id', '=', 'group_user.user_id')
    ->join('groups', 'groups.id', '=', 'group_user.group_id')
    ->select(
       'users.name as name',
       'group_user.user_id as id',
       'groups.name as groupname'
       )
    ->get();
    $view->with('TableB1',$TableB1);
    return $view;

在index.blade.php

<thead>
    <tr>
       <th>Team</th>
       <th>Name</th>
       <th>No. of Showing</th>
       <th>No. of Follow up</th>
       <th>New Lead</th>
       <th>Personal Lead</th>
    </tr>
</thead>
<tbody>
   <?php
     use Carbon\Carbon;
     foreach ($TableB1 as $data){
        echo
            '<tr>
             <th scope="row">'. $data->groupname .'</th>
             <th scope="row">'. $data->name .'</th>';
             // To extract the number of meetings done by each agent(owned_by_id) everyday   
             $meetings = \DB::table('meetings')
                       ->where('company_id', 1)->where('owned_by_id', $data->id)
                       ->where(DB::raw('DAY(created_at)'), Carbon::today()->day);
              echo '<th scope="row">' . $meetings->count() . '</th>';
              // To extract the number of calls done by each agent(owned_by_id) everyday   
              $calls = \DB::table('calls')
                     ->where('company_id', 1)->where('owned_by_id', $data->id)
                     ->where(DB::raw('DAY(created_at)'), Carbon::today()->day);
              echo '<th scope="row">' . $calls->count() . '</th>';
              // To extract the number of leads created by each agent(owned_by_id) everyday   
              $leads = \DB::table('leads')
                     ->where('lead_status_id', 1)->where('company_id', 1)->where('owned_by_id', $data->id)
                     ->where(DB::raw('DAY(created_at)'), Carbon::today()->day);
              echo '<th scope="row">' . $leads->count() . '</th>';
     }
  ?>
  </tr>
</tbody>

如何将php刀片中的代码移动到控制器？
该代码有效，但我认为该代码应该在控制器中正确吗？
并且如果可能的话，有一种方法可以通过AJAX按月份和年份过滤表中的数据，所以我不必刷新页面？

我正在使用Laravel 5.7

在您的控制器中，您可以执行以下操作：

// $TableB1 = ...

// note the & in &$entry.
// The & makes $entry writable in the loop (to say it simply)

foreach ($TableB1 as &$entry){
    $entry->meetingCount = (
        \DB::table('meetings')
        ->where('company_id', 1)->where('owned_by_id', $data->id)
        ->where(DB::raw('DAY(created_at)'), Carbon::today()->day)
    )->count();

    // $entry->callCount = ...
    // $entry->leadCount = ...
}

// $view->with('TableB1',$TableB1);

可以通过直接在SQL中包含所有计数来避免此循环，但是无论如何，让我们继续。

现在，您可以在视图中简单地做到这一点：

'<tr>
     <th scope="row">'. $data->groupname .'</th>
     <th scope="row">'. $data->name .'</th>';
     <th scope="row">'. $data->meetingCount .'</th>';
     <th scope="row">'. $data->leadCount .'</th>';
    ...

奖金：既然您使用Laravel和Blade，为什么不使用其语法？

<tbody>
@foreach($table as $entry)
    <tr>
        <th scope="row">{{$entry->groupname}}</th>
        <th scope="row">{{$entry->name}}</th>
        <th scope="row">{{$entry->meetingCount}}</th>
    </tr>
@endforeach
</tbody>

不需要<?php语句和大量引号。
