使用ajax在页面上显示数据时出现错误

Question

我正在向用户管理页面添加搜索功能，并且正在使用AJAX进行搜索，但是我无法在页面上显示数据。它给出了一个错误。

我尝试在每侧添加单引号或双引号，但这每次都会给我一个错误

这是控制器功能：

public function search(Request $request)
{
    if($request->ajax())
    {
        $output = '';
        $query = $request->get('query');
        if($query != '')
        {
            $data =User::where('name', 'like', '%'.$query.'%')->get();
        }
        else
        {
            $data =User::orderBy('created_at' ,'desc')->get();
        }
        $total_row = $data->count();
        if($total_row > 0)
        {
            foreach($data as $merchant)//That how i am showing data on the page
            {
                $output .=
                "<tr>
                     <td>"{$users->name}"
                        "@if($users->allowded == 0)"  //I need to add these if else functionality to my code but these thing are giving error 
                        "@endif"
                    </td>
                    <td>{{$users->email}}</td>
                    <td>{{$users->permission->permission}}</td>
                    <td>
                        <a href="#" class="btn btn-xs btn-success">

                        </a>

                        </a>
                        <a href="#" class="btn btn-xs btn-success">

                    </td>
                    <td>
                        @if($users->user_status)
                            <a href="" class="btn btn-xs btn-danger"> 
                                <span style="padding-right: 10px;">Make Him Unpaid User
                                </span>
                            </a>
                        @else
                            <a href="" class="btn btn-xs btn-success"> 
                                <span style="padding-right: 16px;">Make Him Paid User
                                </span>
                            </a>
                        @endif  
                    </td>
                    <td>
                        @foreach($cashtransfer as $cash)
                            @if($cash->user_id == $users->id) 
                                {{ $cash->amount}}

                            @endif
                        @endforeach
                    </td>
                    <td>
                        @if($users->allowded)
                            <a href="" class="btn btn-xs btn-danger">
                                <span style="padding-right: 16px;">Bloack User</span>
                            </a>
                        @else
                            <a href="" class="btn btn-xs btn-success">
                                <span style="padding-right: 16px;">Allow User</span>
                            </a>
                         @endif
                    </td>
                    <td>
                    </td>
                    <td>
                        <a href="" class="btn btn-xs btn-danger">
                            <span style="padding-right: 16px;">Delete User</span>
                        </a>
                    </td>
                </tr>";
            }
        }
        else
        {
            //This is The Out Variable which is taking data to the page
            $output = '
            <tr>
                <td align="center" colspan="5">No Data Found</td>
            </tr>';
        }
        $data = array(
            'table_data'  => $output,
            'total_data'  => $total_row
        );
        echo json_encode($data);
    }
}

这些是我每次都会遇到的错误：

    // ->when($request->has('query'), function($q){
           //  $q->where('name','like','%'. request('query').'%');
           // })->get();
           $data =User::where('name', 'like', '%'.$query.'%')->get();

          }
          else
          {
           $data =User::orderBy('created_at' ,'desc')->get();
           // $pagi = "<div> {$data->links()}</div>";
          }
          $total_row = $data->count();
          if($total_row > 0)
          {
           foreach($data as $merchant)
           {
                $output .= "
                    <tr>
        <td>"{$users->name}"
        "@if($users->allowded == 0)"

        "@endif"
        </td>
        <td>{{$users->email}}</td>
        <td>{{$users->permission->permission}}</td>
            <td><a href="#" class="btn btn-xs btn-success"> <span style="padding-right: 16px;">Make Him Salaried User</span></a><a href="#" class="btn btn-xs btn-success"> <span style="padding-right: 16px;">Make Him Commesioned User</span></a><a href="#" class="btn btn-xs btn-success"> <span style="padding-right: 16px;">Make Him Salaried and Commesionded User</span></a></td>



      <td>
        @if($users->user_status)

        <a href="" class="btn btn-xs btn-danger"> <span style="padding-right: 10px;">Make Him Unpaid User</span></a>
        @else

为什么我不能只发布它？
我不断收到错误消息，例如我需要更多详细信息

您不能在普通琴弦内使用刀片。您必须使用普通的PHP来组成输出：

foreach($data as $merchant)
{
    $optionalOutput = $users->allowded == 0 ? 'output if true' : 'output if false';
    $output .= "<tr>
                     <td>{$users->name}
                        {$optionalOutput}
                    </td>";
    // ...
}

或者您可以将代码移至刀片视图：

foreach($data as $merchant)
{
    $output .= view('path.to.view', [$merchant, $users])->render();
}
