Question

我有一个查询，如果性别=＆＃34; mal＆＃34;和女性＆＃34;。

$users[] =  User:: whereIn('gender',array('mal', 'female'))->count()->get();
return view('/',compact('users[]'));

这些计数显示在条形图

中

function drawStacked() {
var genders[] = {{ $users[] }}
var data = google.visualization.arrayToDataTable([
    ['Element', '', { role: 'style' }, { role: 'annotation' } ],
    ['Mal', '#000', genders[0]],
    ['Female', '#000', genders[1]],
 ]);
}

但他只向我展示了性别 mal

的数量

Answer 1

您需要执行两个查询：

$maleCount = User::where('gender', 'male')->count();
$femaleCount = User::where('gender', 'female')->count();
return view('/', compact('maleCount', 'femaleCount'));

Answer 2

这对于Alexey Mezenin的解决方案来说非常好，但是我想在一个地方重新组合并返回数组并在javascript中显示它，例如：genders[0] for mal and genders[1] for female

Answer 3

您只需将Alexey解决方案的结果放入如下数组：

$counts = [
    'male' => User::where('gender', 'male')->count(),
    'female' => User::where('gender', 'female')->count()
];

return view('/', compact('counts'));

然后您可以在以下视图中访问它们：

$counts['male']
// or
$counts['female']

Laravel在javascript中从控制器获取两个值数组计数
