Laravel - 集团当天（周一，周二，等）

Question

我有下表：

TABLE:schedule

id   day  name 
 -----------------------------
1    Mon   test  
2    Mon   hello
3    Tue   another
4    Tue   here
5    Wed   go

我有一个Laravel模型，所以我想尝试分组 这是我想要作为对象的结果：

['Mon']-> array[0]='name'=>test,
         array[1]='name'=>hello,
['Tue']-> array[0]='name'=>another,
         array[1]='name'=>here,

这是我在HomeController中的代码：

$schedule = DB::table('schedule')
             ->select('*')
             ->groupBy('day')
             ->get();

这不仅仅显示一天而且没有分组，有谁知道为什么？

Answer 1

这是一个有点复杂的问题。我想，你看起来像下面这样：

    $schedules = DB::table('schedule')
                 ->selectRaw('id, day, group_concat(name) as name')
                 ->groupBy('day')
                 ->get();

    $data = array();

    foreach ($schedules as $schedule) {
        $data[$schedule->day][] = explode(",",$schedule->name);
    }

   var_dump($data);

输出：

array (size=3)
  'Mon' => 
    array (size=1)
      0 => 
        array (size=12)
          0 => string 'test' (length=4)
          1 => string 'hello' (length=5)
  'Tue' => 
    array (size=1)
      0 => 
        array (size=3)
          0 => string 'another' (length=6)
          1 => string 'here' (length=4)
  'Wed' => 
    array (size=1)
      0 => 
        array (size=1)
          0 => string 'go' (length=2)

修改

为额外字段做另一个group_concat。

$schedules = DB::table('schedule')
                 ->selectRaw('id, day, group_concat(name) as name, group_concat(city) as city')
                 ->groupBy('day')
                 ->get();

    $data = array();

    foreach ($schedules as $schedule) {
        $data[$schedule->day]['name'] = explode(",",$schedule->name);
        $data[$schedule->day]['city'] = explode(",",$schedule->city);
    }

   var_dump($data);
