不好意思,我是学习Laravel的新手,我对表单输入显示数据值有疑问。 我有create.blade.php:
@extends('layouts.master')
@section('content')
<div class="container">
<div class="header">
<h1><b>Create an account</b></h1>
<h5>Welcome to Konoha Village</h5>
</div>
{{ csrf_field() }}
@if(isset($name))
<div class="alert alert-warning alert-dismissible" role="alert">
Halo <strong>{{$name}}</strong>
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">$times;</span>
</button>
</div>
@endif
<div class="form">
<form action="{{ url('final-test') }}" method="post" id="form1">
<div class="form-group">
<input name="name" id="name" class="form-control" placeholder="Your Full Name"/>
</div>
<br>
<div class="form-group">
<input style="cursor:pointer" type="submit" class="btn btn-primary" id="submit" value="Show into Dashboard">
</div>
<div class="form-group">
</div>
</form>
</div>
</div>
@endsection
我的控制器名为AccController.php:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class AccController extends Controller
{
public function create() {
return view('home.create');
}
public function show(Request $r) {
$soul = $r ->name;
$pesan = "Your name is {$r->name}";
}
}
和我在web.php中的路线:
//route to get play form
Route::get ('start', 'AccController@create' )->name('home.create');
Route::post('final-test', 'AccController@show');
我想在另一个页面视图中显示我调用了show.blade.php:
@extends('layouts.master')
@section('content')
<div>
{{$name = Input::get('name')}}
<h1>Your name is {{ $pesan }}</h1> </div>
@endsection
最后没有任何错误,但它无法显示输入表单中的值,请问我帮忙吗?
此致,Aga。

您不是在这里遵守惯例。 show方法是来自数据库的数据。为了显示表单数据,您已在store方法中执行此操作
HTML代码
html表单应该有一些小的改动
{{--Changing in just action--}}
{{-- If it doesn't accept that action then replace it with {{AccController.php@store}} --}}
<form action="AccController.php@store" method="post" id="form1">
<div class="form-group">
<input name="name" id="name" class="form-control" placeholder="Your Full Name"/>
</div>
<br>
<div class="form-group">
<input style="cursor:pointer" type="submit" class="btn btn-primary" id="submit" value="Show into Dashboard">
</div>
<div class="form-group">
</div>
</form>
然后在Controller中,您将获得商店功能
中的表单数据 public function store(Request $r) {
$soul = $r ->name;
$pesan = "Your name is {$r->name}";
return $pesan;
}
你在route.php中犯了一些错误。你只需遵循laravel为我们提供的惯例。
用此替换您的路线代码。
Route::resource('/posts', 'AccController.php');
这里它会自动调用Controller的所有默认功能,并为它们分配特定的路由。例如在图片下方
您只需在终端或命令提示符下键入php artisan route:list
,您将看到已创建的路由列表以及laravel为您创建的路由列表以及方法,URI和名称。您只需遵循惯例,它将自动为您提供结果

您的web.php
:
//route to get play form
Route::get('/start', 'AccController@create')->name('home.create');
Route::post('/final-test', 'AccController@show')->name('home.show');
在路线最终测试中添加了名称home.show
。
您的AccController.php
:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class AccController extends Controller
{
public function create()
{
return view('home.create');
}
public function show(Request $r)
{
$soul = $r->name;
return view('home.show')->with('soul', $soul);
}
}
您的show.blade.php
:
@extends('layouts.master')
@section('content')
<div>
<h1>Your name is {{ $soul }}</h1>
</div>
@endsection
您的create.blade.php
:
@extends('layouts.master')
@section('content')
<div class="container">
<div class="header">
<h1><b>Create an account</b></h1>
<h5>Welcome to Konoha Village</h5>
</div>
@if(isset($name))
<div class="alert alert-warning alert-dismissible" role="alert">
Halo <strong>{{$name}}</strong>
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">$times;</span>
</button>
</div>
@endif
<div class="form">
<form action="{{ route('home.show') }}" method="post" id="form1">
{{ csrf_field() }}
<div class="form-group">
<input name="name" id="name" class="form-control" placeholder="Your Full Name"/>
</div>
<br>
<div class="form-group">
<input style="cursor:pointer" type="submit" class="btn btn-primary" id="submit" value="Show into Dashboard">
</div>
<div class="form-group">
</div>
</form>
</div>
</div>
@endsection
以下是最重要的更改:我在表单中移动{{ csrf_field() }}
,因此您无法获取The page has expired due to inactivity. Please refresh and try again.
并将表单操作更改为指定路由{{ route('home.show') }}
。
我保留了您的<span aria-hidden="true">$times;</span>
,但这只会显示$times;
,可能需要调整一下。
