Question

我有一个表从数据库中获取数据，而不是我需要一次更新所有行。在每个单元格中，我添加了输入字段。现在我希望能够在输入数据时立即更新所有用户，但我不知道如何。

以下是我的观点图片：

enumerable:false

//控制器

@extends('admin/master')
@section('content')

<section class="content">
    {{Form::open()}}
    <div class="row">
        <div class="col-xs-12">
            <div class="box">
                <div class="box-header">
                    <div class="col-lg-4">
                        <h3 class="box-title">INPUT EXAM RESULTS FOR EACH STUDENT: </h3>

您的输入元素必须是数组，由$row->id键入（我假设这是学生表的主键），以识别该行所代表的学生。例如：

<td><input type="text" name="sub1[{{ $row->id}}]" class="form-control" placeholder="Add marks here..."></td>

然后，当您提交数据时，按数组键查找学生并相应地更新其信息。有什么影响：

$key = // extract id from sub1 array
Student::find($request->input($key));
// do updates here
// repeat for each sub input...

一次保存多个表行（Laravel 4）
