php 使用Array编辑数据，但结果与Laravel相同

我想使用数组编辑数据，但是当我提交编辑时，下面的结果都是一样的。

当编辑每个学生的名字时，它有一个不同的值，但当提交时，结果都是一样的，就像在MySQL和Web中一样：

代码：

public function UpdateEditGradeStudent(Request $request){
    $data = GradeDetail::find($request->id_grade_detail);

    foreach($request->id_grade as $index => $value) {
        DB::table('grade_details')
            ->update(array(
                'id_grade' => $value,
                'quiz' => $request->quiz[$index],
                'assignment' => $request->assignment[$index],
                'min_text' => $request->min_text[$index],
                'd_t' => $request->d_t[$index],
                'final_text' => $request->final_text[$index],
                'total' => $request->total[$index],
            ));
        
    }

    return redirect('/');
}

我没有截图所有的***刀片***编码。
如何编辑***数据数组***根据我们已经编辑过的数据。

您的键似乎是id_grade_detail，您应该按该字段进行筛选：

@forelse($subject as $data)
    <input
        type="hidden"
        name="id_grade_detail[]"
        value="{{$data->id_grade_detail}}"
    >
    <input
        type="hidden"
        name="id_grade[]"
        value="{{$data->id_grade}}"
    >
    ...

在服务器上：

public function UpdateEditGradeStudent(Request $request)
{
    foreach($request->id_grade_detail as $index => $value) {
        $grade_detail = GradeDetail::find($value);
        if ($grade_detail) {
            $grade_detail->quiz = $request->quiz[$index];
            $grade_detail->assignment = $request->assignment[$index];
            $grade_detail->min_text = $request->min_text[$index];
            $grade_detail->d_t = $request->quiz[$index];
            $grade_detail->final_text = $request->final_text[$index];
            $grade_detail->total = $request->total[$index];
            
            $grade_detail->save();
        }
    }

    return redirect('/');
}
