Question

我正在使用PHP Laravel。

我需要获得每位员工的总时间/小时数。每个员工都有一个指定的timeKeeping_empID。 Time_Logs表有Employees的时间日志，timeKeeping_empID作为外键。

我尝试运行我的代码：控制器：

ViewContainerRef.createComponent

在我看来： $ totalHours = 0;

function getTotalHours(Request $request)
        {

            $team = Employees::where('managerID', $request->session()->get('employeeID'))->get();
                //I am assigning an array to be grouped according to my employeeID session.
                $teamIDs = array();
                //I am getting my own session so I can see my data as well together with my team
                array_push($teamIDs, $request->session()->get('employeeID'));
                foreach($team as $member) {
                    array_push($teamIDs, $member->employeeID);
                }
                //I am getting the column employeeID which is the same with the teamID
                $empData = Employees::whereIn('employeeID', $teamIDs)->get();
                $timeKeepingIDs = array();
                foreach($empData as $anEmpData) {
                    array_push($timeKeepingIDs, $anEmpData->timeKeeping_empID);
                }
                $timeLogData = Time_Logs::whereIn('timeKeeping_empID', $timeKeepingIDs)->get();

            return view('welcome', compact('timeLogData','request'));
        }

但结果是所有员工的总工时。我需要的是每个员工的总小时数。

这是我的数据库表：

        foreach ($timeLogData as $timeLogDatas) {

        $dateToday = new DateTime($timeLogDatas->date);
        $timeFrom = date_create($timeLogDatas->time_in);
        $timeTo = date_create($timeLogDatas->time_out);
        $hoursRendered = date_diff($timeFrom, $timeTo);

        $totalHours=$totalHours += (int) $hoursRendered->format('%h');
        }
        echo "$totalHours";

抱歉，我是PHP的新手。

作为MVC模式的原则问题，您不应该将应用程序逻辑放在View中;将所有计算逻辑放在Controller中，并在视图中输出计算值。

话虽如此，您获取所有员工的时间数据之所以是因为您将整个员工ID号数组传递给了timelogdata的Where子句：

$timeLogData = Time_Logs::whereIn('timeKeeping_empID', 的 $ timeKeepingIDs )->get();

通过传递一系列员工编号，您基本上可以获得$ timeKeepingIDs数组中所有员工的合并时间日志。

有很多方法可以解决这个问题，但最简单的方法可能是为每位员工创建一个总计小时数的关联数组。您必须遍历$ empData数组中的每个雇员，执行计算，并保存单独的$ timesheets数组，如：

//I am getting the column employeeID which is the same with the teamID $empData = Employees::whereIn('employeeID', $teamIDs)->get(); $timesheets = array(); foreach($empData as $anEmpData) { $timeLogData = Time_Logs::whereIn('timeKeeping_empID', $anEmpData->timeKeeping_empID)->get(); $totalHours = 0; $timeLogs = array(); foreach($timeLogData as &$t) { $timeData['dateToday'] = new DateTime($t->date); $timeData['timeFrom'] = date_create($t->time_in); $timeData['timeTo'] = date_create($t->time_out); $timeData['hoursRendered'] = date_diff($timeFrom, $timeTo); array_push($timeLogs, $timeData); $totalHours=$totalHours += (int) $hoursRendered->format('%h'); } $timesheets[$anEmpData->timeKeeping_empID] = [ 'timeLogs' => $timeLogs, 'totalHours' => $totalHours ]; } return view('welcome', compact('timesheets','request'));

现在，根据您的观点，您可以使用@foreach Blade指令：

<?php @foreach ($timesheets as $empid => $timesheet) <p>Timesheet for employee id $empid</p> @foreach ($timesheet['timeLogs'] as $timeLog) <ul> @foreach ($timeLog as $logEntry) <li>Date: $logEntry['dateToday']</li> <li>Time In: $logEntry['timeFrom']</li> <li>Time Out: $logEntry['timeTo']</li> <li>Hours rendered: $logEntry['hoursRendered']</li> @endforeach </ul> @endforeach Total hours rendered is: $timesheet['totalHours'] @endforeach ?>

我还没有在我的电脑上对此进行测试，但我希望你明白这一点。

希望这有帮助！

我认为你应该做的是一系列小时而不是将所有这些小时总结在一起：

    foreach ($timeLogData as $timeLogDatas) {

    $dateToday = new DateTime($timeLogDatas->date);
    $timeFrom = date_create($timeLogDatas->time_in);
    $timeTo = date_create($timeLogDatas->time_out);
    $hoursRendered = date_diff($timeFrom, $timeTo);

    $totalHours[$timeLogDatas->timeKeeping_empID] = $totalHours[$timeLogDatas->timeKeeping_empID] + (int) $hoursRendered->format('%h');
    }
    print_r("$totalHours");

然后您将拥有一个包含员工总小时数的数组。然后你会有一个输出：

Array
(
    [123] => 120
    [124] => 95
    [129] => 195
)

其中密钥是员工ID，以及值，即他的总小时数。

嘿，我会告诉你Laravel魔法：P

function getTotalHours(Request $request)
{
$timeLogData = Time_Logs::groupBy('timeKeeping_empID')->selectRaw('sum(time_out-time_in) as workingHours, timeKeeping_empID')->lists('workingHours','timeKeeping_empID');
}

在您的视图中

foreach ($timeLogData as $timeLogDatas) {
{{$timeLogDatas->user->name}} - {{$timeLogDatas->workingHours}}
}

在 Time_Logs 模型中，您必须使用此功能

public function user()
    {
        return $this->belongsTo('App\Employee','EmployeeID');
    }

EXtra：我猜您必须将此用于 Time_Logs

protected $dates = [
        'log_in',
        'log_out',

    ];

PHP：根据键在foreach中分隔值
