Laravel 语法：：parameterize（）：参数#1（$values）的类型必须为array、string给定、called

这是我的控制器，名为“AttendanceController”

这是我的出席。在有表格提交的地方创建

<form method="post" action="{{route('attendances.store')}}">
        @csrf
        <table>

                <tr>
                    <th><p style="margin: 20px">Name : </p></th>
                    <th><p style="margin: 20px">Attendance : </p></th>
                    <th><p style="margin: 20px">Date : </p></th>
                </tr>
            @foreach ($students as $student)
                <tr>
                    <th><p style="margin: 20px">{{ $student->name }}</p></th>
                    <input name="id[]" type="hidden" value="{{ $student->id }}">

您的输入名称会导致冲突。您发送了多个学生的表单字段，但未确认这些字段

我并没有检查代码，但我希望你们会明白

        @csrf
        <table>

                <tr>

哪一行抛出这个错误？无论如何，我在

store

function

$students=Student:：all（）上发现了一行不必要的内容
