本文介绍了Laravel表格数据不保存在neo4j图形数据库中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我写了一个 laravel form ，它的屏幕截图如下：
我使用neo4j存储表单数据。
这里是代码：
app / views / duck-form.blade.php
<！doctype html>
< html>
< head>
< title> Laravel表单验证！< /标题>
<！ - load bootstrap - >

@if（$ errors-> has（'email'））< p class =help-block> {{$ errors-> first（'email'）}}< / p> ; @endif
< / div>
$ b< div class =form-group @if（$ errors-> has（'password'））has-error @endif>
< label for =password>密码< / label>
< input type =passwordid =passwordclass =form-controlname =password>
@if（$ errors-> has（'password'））< p class =help-block> {{$ errors-> first（'password'）}}< / p> ; @endif
< / div>
< div class =form-group @if（$ errors-> has（'password_confirm'））has-error @endif>
< label for =password_confirm>确认密码< / label>
< input type =passwordid =password_confirmclass =form-controlname =password_confirm>
@if（$ errors-> has（'password_confirm'））< p class =help-block> {{$ errors-> first（'password_confirm'）}}< / p> ; @endif
< / div>
< button type =submitclass =btn btn-success>提交< / button>
< / form>
< / div>
< / div>
< / body>
< / html>
1。我向 app / config / app.php 中的providers数组添加了'Artdarek\Neo4j\Neo4jServiceProvider'
2.我在 app / config / database.php中添加了 neo4j 配置
'neo4j'=> [
'default'=> [
'host'=> 'localhost'，
'port'=> 7474，
'username'=> null，
'password'=>空，
]，
]，
<3>。然后我为该表单添加了一个控制器：
<？php
class DuckController extends BaseController {
public function showWelcome（）
{
return View :: make（'duck'）;
}
}
4。这是我的 routes.php 。
$ b $
<？php
路由:: get（'/'，function（）
{
return View :: make（'hello'）;
}）;
//显示鸭子形式的路由
Route :: get（'ducks'，function（）
{
return View :: make（'duck-表格'）;
}）;
//处理鸭子的路由形式
Route :: post（'ducks'，array（''''=&';'csrf'，function（）
{
//创建验证规则------------------------
$ rules = array（
'name'=>'required'，//只是一个普通的必需验证
'email'=>'required | email | unique：ducks'，//必须且必须在鸭表中唯一
'password'=>'required'，
'password_confirm'=>'required | same：password'//必须匹配密码字段
）;
//创建自定义验证消息------------------
$ messages = array（
'required'=>'The：attribute '，
'same'=>'The：others must match。'
）;
//做验证----- ------------------------ -----
//根据我们的表单输入验证
$ validator = Validator :: make（Input :: all（），$ rules，$ messages）;
//检查验证器是否失败-----------------------
if（$ validator-> failed （））{
//用错误消息重定向用户
$ messages = $ validator-> messages（）;
//也会将它们重新导向回旧的输入，所以它们不需要再次填写表单
//但是我们不会用输入的密码重定向它们
返回Redirect :: to（'ducks'）
- > withErrors（$ validator）
- > withInput（Input :: except（'password'，'password_confirm'））;
} else {
//验证成功---------------------------
//我们的鸭子已通过所有测试！
//让他进入数据库
//为我们的鸭子创建数据
$ duck = new Duck;
$ duck-> name = Input :: get（'name'）;
$ duck-> email = Input :: get（'email'）;
$ duck-> password = Hash :: make（Input :: get（'password'））;
//保存我们的鸭子
$ duck-> save（）;
//重定向--------------------------------------- -
//将用户重定向到表单，以便他们可以重做
return Redirect :: to（'ducks'）
- > with（'messages'，'万岁'）！;
}
}））;
5。这是我的 form 的模型文件：
<？php
class Duck扩展雄辩{
protected $ fillable = array（'name'，'email'，'password'）;
}
6。这是我对 neo4j 的模型：
<？php
//使用Illuminate\Auth\EloquentUserProvider;
类数据库扩展Eloquent {
公共函数索引（$ name，$ email，$ password，$ password_confirm）{
$ formData = Neo4j :: makeNode（）;
$ formData-> setProperty（'name'，$ name）
- > setProperty（'email'，$ email）
- > setProperty（'password'，$ password）
- > setProprty（'password_confirm'，$ password_confirm）
- > save（）;
}
}
当我点击在那个提交按钮中，我得到这个错误：
[ 编辑 ]
我在工作就此：
这是我得到的新错误：
它是 csrf 令牌问题吗？
它指向：
Route :: filter（'csrf'，function（）
{
if（Session :: token（）！= Input :: get（'_ token'））
{
throw new Illuminate \Session\TokenMismatchException;
}
}）;
我无法解决它，因为5小时后数据没有储存在neo4j DB中。我该如何解决它？ 使用 CSRF保护过滤器时，必须声明您的表单。 在你的刀片中：
{{Form :: open（array（'method'=&';'''''' action'=> URL :: to（/ ducks）））}}
：
{{Form :: close（）}}
这会在您的html中呈现与使用相同的表单：
< form method =POSTaction ={{URL :: to（/ duck）}}> ...< / form>
但也会添加隐藏的
_token元素您缺少：
< input type =hiddenname =_ tokenvalue =value_of_token/>
希望有帮助！
编辑
或者，如果您不想重新创建
< form>你可以简单地使用：
$ p ${{Form :: token（）}}
您现有的< form> 标签内的某处可以创建它。
I wrote a laravel form, its screen shot is as given below:
And I use neo4j for storing that form data.
Here is the code:
app/views/duck-form.blade.php
<!doctype html>
<html>
<head>
<title>Laravel Form Validation!</title>
<!-- load bootstrap -->
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<style>
body { padding-bottom:40px; padding-top:40px; }
</style>
</head>
<body class="container">
<div class="row">
<div class="col-sm-8 col-sm-offset-2">
<div class="page-header">
<h1><span class="glyphicon glyphicon-flash"></span> Register! </h1>
</div>
@if ($errors->has())
<div class="alert alert-danger">
@foreach ($errors->all() as $error)
{{ $error }}<br>
@endforeach
</div>
@endif
<!-- FORM STARTS HERE -->
<form method="POST" action="/ducks" novalidate>
<div class="form-group @if ($errors->has('name')) has-error @endif">
<label for="name">Name</label>
<input type="text" id="name" class="form-control" name="name" placeholder="Enter your name" value="{{ Input::old('name') }}">
@if ($errors->has('name')) <p class="help-block">{{ $errors->first('name') }}</p> @endif
</div>
<div class="form-group @if ($errors->has('email')) has-error @endif">
<label for="email">Email</label>
<input type="text" id="email" class="form-control" name="email" placeholder="Enter your email id" value="{{ Input::old('email') }}">
@if ($errors->has('email')) <p class="help-block">{{ $errors->first('email') }}</p> @endif
</div>
<div class="form-group @if ($errors->has('password')) has-error @endif">
<label for="password">Password</label>
<input type="password" id="password" class="form-control" name="password">
@if ($errors->has('password')) <p class="help-block">{{ $errors->first('password') }}</p> @endif
</div>
<div class="form-group @if ($errors->has('password_confirm')) has-error @endif">
<label for="password_confirm">Confirm Password</label>
<input type="password" id="password_confirm" class="form-control" name="password_confirm">
@if ($errors->has('password_confirm')) <p class="help-block">{{ $errors->first('password_confirm') }}</p> @endif
</div>
<button type="submit" class="btn btn-success">Submit</button>
</form>
</div>
</div>
</body>
</html>
1. I added 'Artdarek\Neo4j\Neo4jServiceProvider' to providers array in app/config/app.php.
2. I added neo4j configuration in app/config/database.php
'neo4j' => [
'default' => [
'host' => 'localhost',
'port' => 7474,
'username' => null,
'password' => null,
],
],
3. Then I added a controller for that form:
<?php
class DuckController extends BaseController {
public function showWelcome()
{
return View::make('duck');
}
}
4. This is my routes.php.
<?php
Route::get('/', function()
{
return View::make('hello');
});
// route to show the duck form
Route::get('ducks', function()
{
return View::make('duck-form');
});
// route to process the ducks form
Route::post('ducks', array('before' => 'csrf', function()
{
// create the validation rules ------------------------
$rules = array(
'name' => 'required', // just a normal required validation
'email' => 'required|email|unique:ducks', // required and must be unique in the ducks table
'password' => 'required',
'password_confirm' => 'required|same:password' // required and has to match the password field
);
// create custom validation messages ------------------
$messages = array(
'required' => 'The :attribute is really really really important.',
'same' => 'The :others must match.'
);
// do the validation ----------------------------------
// validate against the inputs from our form
$validator = Validator::make(Input::all(), $rules, $messages);
// check if the validator failed -----------------------
if ($validator->fails()) {
// redirect our user back with error messages
$messages = $validator->messages();
// also redirect them back with old inputs so they dont have to fill out the form again
// but we wont redirect them with the password they entered
return Redirect::to('ducks')
->withErrors($validator)
->withInput(Input::except('password', 'password_confirm'));
} else {
// validation successful ---------------------------
// our duck has passed all tests!
// let him enter the database
// create the data for our duck
$duck = new Duck;
$duck->name = Input::get('name');
$duck->email = Input::get('email');
$duck->password = Hash::make(Input::get('password'));
// save our duck
$duck->save();
// redirect ----------------------------------------
// redirect our user back to the form so they can do it all over again
return Redirect::to('ducks')
->with('messages', 'Hooray!');
}
}));
5. This is my model file for form:
<?php
class Duck extends Eloquent {
protected $fillable = array('name', 'email', 'password');
}
6. This is my model for neo4j:
<?php
//use Illuminate\Auth\EloquentUserProvider;
class database extends Eloquent {
public function index($name, $email, $password, $password_confirm) {
$formData = Neo4j::makeNode();
$formData->setProperty('name',$name)
->setProperty('email',$email)
->setProperty('password',$password)
->setProprty('password_confirm',$password_confirm)
->save();
}
}
When I click on that submit button in that form, I get this error:
[ Edit ]
I was working on it:
This is the new error which I got:
Is it a csrf token issue?
It is pointing to:
Route::filter('csrf', function()
{
if (Session::token() != Input::get('_token'))
{
throw new Illuminate\Session\TokenMismatchException;
}
});
I'm unable to resolve it since 5 hours and data isn't getting stored in neo4j DB. How can I fix it?
解决方案
When using the CSRF Protection Filter, your form must be declared in your blade as such:
{{ Form::open(array('method' => 'POST', 'action' => URL::to("/ducks"))) }}
And closed:
{{ Form::close() }}
This will render the same form in your html as using:
<form method="POST" action="{{ URL::to("/ducks") }}">...</form>
But will also add the hidden _token element that you are missing:
<input type="hidden" name="_token" value="value_of_token"/>
Hope that helps!
Edit
Or, if you don't want to recreate your <form>, you may simply use:
{{ Form::token() }}
Somewhere inside your existing <form> tag to create it.
