如何在laravel 5.2中验证电话号码? [英] How to validate phone number in laravel 5.2?

问题描述

我想验证用户输入的电话号码，其中电话号码应恰好为11，以01开头，值字段应仅为电话号码.如何使用Laravel验证来实现?

I want to validate user input phone number where number should be exactly 11 and started with 01 and value field should be number only. How do I do it using Laravel validation?

这是我的控制人:

  public function saveUser(Request $request){
        $this->validate($request,[
            'name' => 'required|max:120',
            'email' => 'required|email|unique:users',
            'phone' => 'required|min:11|numeric',
            'course_id'=>'required'
            ]);

        $user = new User();
        $user->name=  $request->Input(['name']);
        $user->email=  $request->Input(['email']);
        $user->phone=  $request->Input(['phone']);
        $user->date = date('Y-m-d');
        $user->completed_status = '0';
        $user->course_id=$request->Input(['course_id']);
        $user->save();
       return redirect('success');

    }

推荐答案

一种可能的解决方案是使用正则表达式.

One possible solution would to use regex.

'phone' => 'required|regex:/(01)[0-9]{9}/'

这将检查输入以01开头，后跟9个数字.通过使用正则表达式，您不需要numeric或size验证规则.

This will check the input starts with 01 and is followed by 9 numbers. By using regex you don't need the numeric or size validation rules.

如果您想在其他地方重复使用此验证方法，则最好创建自己的验证规则以验证电话号码.

If you want to reuse this validation method else where, it would be a good idea to create your own validation rule for validating phone numbers.

文档:自定义验证

在您的AppServiceProvider的boot方法中:

Validator::extend('phone_number', function($attribute, $value, $parameters)
{
    return substr($value, 0, 2) == '01';
});

这将允许您在应用程序中的任何地方使用phone_number验证规则，因此您的表单验证可以是:

This will allow you to use the phone_number validation rule anywhere in your application, so your form validation could be:

'phone' => 'required|numeric|phone_number|size:11'

在验证程序扩展程序中，您还可以检查$value是否为数字且长度为11个字符.

In your validator extension you could also check if the $value is numeric and 11 characters long.
