这是我的表格 wys_attendence ：
id studid adate amonth ayear acls_id attendence
1 28 02 07 2015 10 1
2 31 02 07 2015 10 0

10 31 31 07 2015 10 1
11 32 31 07 2015 10 1

如何检查每个学生的总和，其中amonth = 07，ayear = 2015年，注意力= 1
我的输出不正确
RollNo StudentName 02 13 14 15 16 17 20 Total PresentsTotal Absents
28 Gokul p p p p a p p 5 2
31 Goku p p p a p p p 5 2
32 Gok p p p p p a a 5 2
我得到了最后一个学生的值关注度= 1且注意力= 0
如何让所有学生计算价值关注度= 1，并且注意力= 0次。
我想要这样
RollNo StudentName 02 13 14 15 16 17 20 Total Presents TotalAbsents
28 Gokul p p p p a p p 6 1
31 Goku p p p a p p p 6 1
32 Gok p p p p p a a 5 2
我的controller.php
` $attendence_tbl = WysAttendancename::where('cls_id',$id)->first();
$wys_attendence_table = $attendence_tbl->attendance_name;
$attendance = DB::table($wys_attendence_table)
->where('amonth',$amonth)
->where('ayear',$ayear)
->groupBy('adate')

$stud_attend = DB::table($wys_attendence_table)

->where('ayear',$ayear)
->where('attendence',0)

}`
我的view.blade.php
`@foreach($students as $student)
@if($student->studcls == $id)
<tr> <td>{{$student->id}}</td>
<td>{{$student->studname}}</td>
@foreach($stud_attend as $stud_attends)
@if($student->id == $stud_attends->studid)
@if($stud_attends->attendence == 1)
<td><font color="green" size="3">p</font></td>
@elseif($stud_attends->attendence == 0)
<td><font color="red" size="3">a</font></td>
@endif
@endif
@endforeach
<td>{{$cunt1}}</td>
<td>{{$cunt0}}</td>
</tr>
@endif
@endforeach`
如何解决我的问题？
我尝试回显method..var_dump（$ cunt1）我得到了正确答案int（6）int（6）int（5）和var_dump（$ cunt0）是int（1）int（1）int（2）
但是在view.blade.php上运行我得到5 5 5和2 2 2所有studid的最后一个值。
如何修改我的view.blade.php代码？
答案 0 :(得分：0)
