Laravel Datatable 默认搜索不适用于自定义过滤器

Question

我在 laravel 中使用 yajra 数据表。我已经实现了该表。除了搜索之外，它工作正常。我也有一个自定义过滤器。
下面的代码显示了数据表初始化和 ajax 请求。用户类型过滤器工作正常。

<script>
    $(document).ready(function() {
            var table = $('#dataList').DataTable({
                processing: true,
                serverSide: true,
                ajax: {
                    url: "{{ route('users.user.index') }}",
                    data: function (d) {
                        d.user_type = $('#user_type_filter').val();
                    }
                },
                columns: [
                    {data: 'DT_RowIndex', name: 'DT_RowIndex'},
                    {data: 'name', name: 'name'},
                    {data: 'email', name: 'email'},
                    {data: 'phone', name: 'phone'},
                    {data: 'action', name: 'action', orderable: false, searchable: false},
                ]
            });
        $('#search-form').on('submit', function(e) {
            table.draw();
            e.preventDefault();
        });            
    } );
</script>

用于过滤用户类型的后端索引页

public function index(Request $request)
{
    /**
     * Ajax call by datatable for listing of the users.
     */
    if ($request->ajax()) {
        $data = User::with('userType')->get();
        $datatable =  DataTables::of($data)
            ->filter(function ($instance) use ($request) {                    
                if ($request->has('user_type') && $request->get('user_type')) {
                    $instance->collection = $instance->collection->filter(function ($row) use ($request) {
                        //return Str::contains($row['phone'], $request->get('phone')) ? true : false;
                        return $row['user_type_id'] == $request->get('user_type');
                    });
                }  
               if ($request->input('search.value') != "") {
                     $instance->collection = $instance->collection->filter(function ($row) use ($request) {
                        return Str::contains($row['name'], $request->input('search.value')) ? true : false;
                    });
                }                                      
            })             
            ->addIndexColumn()
            ->addColumn('action', function ($user) {
                return view('users.datatable', compact('user'));
            })
            ->rawColumns(['action'])
            ->make(true);
        return $datatable;
    }

    $user_type = UserType::pluck('user_type','id')->all();
    $users = User::with('userType')->paginate(25);

    return view('users.index', compact('users','user_type'));
}

此代码仅在当前页面上生成搜索。

你应该像这样尝试

   filterColumn('name', function($query, $keyword) {
                    $sql = "name like ?";
                    $query->whereRaw($sql, ["%{$keyword}%"]);
                })
