Laravel 5.2 新特性系列 -- 表单数组输入验证功能实现
Laravel 5.2 新增表单 数组 输入验证,听起来很懵?下面我们以一个具体例子来演示这一功能。
首先在 routes.php 定义相应路由:
Route::get('form','TestController@form');Route::post('form/validate','TestController@validate');
然后使用Artisan命令创建对应控制器:
php artisan make:controller TestController
编辑生成的 TestController.php 文件内容如下:
<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;use App\Http\Requests;use App\Http\Controllers\Controller;class TestController extends Controller{ public function form() { return view('test.form'); } public function validate(Requests\FormRequest $request) { return 'success'; }}
接下来创建表单视图文件 resources/views/test/form.blade.php ,编辑 form.blade.php 文件内容如下:
@extends('layouts.app')@section('content') <div class="container"> <div class="row"> @if (count($errors) > 0) <div class="alert alert-danger"> <ul> @foreach ($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> </div> @endif <form action="{{url('form/validate')}}" method="POST"> {!! csrf_field() !!} <label>Company Name</label> <input type="text" name="name"> <h3 id="Employees">Employees</h3> <div class="add-employee"> <label>Employee Name</label> <input type="text" name="employee[1][name]"> <label>Employee Title</label> <input type="text" name="employee[1][title]"> </div> <div class="add-employee"> <label>Employee Name</label> <input type="text" name="employee[2][name]"> <label>Employee Title</label> <input type="text" name="employee[2][title]"> </div> <input type="submit"> </form> </div> </div>@endsection
我们在表单中定义了数组输入字段 employee[][name] 和 employee[][title] ,以便同时输入多个员工姓名和职位。
此外,注意到我们在控制器 TestController 的 validate 方法中注入了 FormRequest 请求类,我们将在这个类中实现表单输入验证逻辑,下面我们使用Artisan命令生成这个请求类:
php artisan make:request FormRequest
这样会在 app/Http/Requests 目录下生成 FormRequest.php ,编辑该文件内容如下:
<?phpnamespace App\Http\Requests;use App\Http\Requests\Request;class FormRequest extends Request{ /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return true; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { return [ 'name'=>'required|max:100', 'employee.*.name'=>'required|max:100', 'employee.*.title'=>'required|max:100' ]; }}
至此,我们已经完成代码编写工作,下面我们来测试数组输入验证,在浏览器中访问 http://laravel.app/form ,页面显示如下:
我们接下来输入一些表单数据:
最后,点击“提交”按钮,显示验证错误提示信息:

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

In PHPOOP, self:: refers to the current class, parent:: refers to the parent class, static:: is used for late static binding. 1.self:: is used for static method and constant calls, but does not support late static binding. 2.parent:: is used for subclasses to call parent class methods, and private methods cannot be accessed. 3.static:: supports late static binding, suitable for inheritance and polymorphism, but may affect the readability of the code.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.
