有没有办法在eloquent查询生成器中追加或包含单独的select函数?
实际的 - > select()先前设置,然后调用此函数.我想在后面的函数中有条件地添加count列,该函数将查询传递给它.

为了将来参考,您可以使用addSelect()函数.
在文档中有好处,但您可以在API中找到它:http://laravel.com/api/4.2/Illuminate/Database/Query/Builder.html#method_addSelect

尝试这个:
$thing_query->groupBy($value)->get(DB::raw('COUNT('.$value.') as count'));
另外,如果您只是想获取计数而不选择多个内容,您可以->count()
使用->get()
