带有通配符的 Laravel 验证器

问题描述

我想制作一个 Laravel 验证器来验证数组内的未命名数组 ( 0,1,2,3 ) 内的字段

i want to make a laravel validator that validates the the fields inside an un-named array ( 0,1,2,3 ) that is inside an array

所以我的数组就像

array [ //the form data
  "items" => array:2 [ //the main array i want to validate
    0 => array:2 [ // the inner array that i want to validate its data
      "id" => "1"
      "quantity" => "1000"
     ]
    1 => array:2 [
     "id" => "1"
     "quantity" => "1000"
     ]
  // other fields of the form,
  ]

]

所以我想要的是像

  $validator = Validator::make($request->all(), [
     'items.*.id' => 'required' //notice the star *
  ]);

推荐答案

Laravel 5.2

现在支持问题中的语法

http://laravel.com/docs/master/validation#validating-arrays

Laravel 5.1

首先使用您的所有其他规则创建验证器.对项目使用 array 规则

First create the validator with all of your other rules. Use the array rule for items

$validator = Validator::make($request->all(), [
    'items' => 'array',
    // your other rules here
]);

然后使用 Validator each 方法将一组规则应用于 items 数组中的每个项目.

Then use the Validator each method to apply a set of rules to every item in the items array.

$validator->each('items', [
    'id'       => 'required',
    'quantity' => 'min:0', 
]);

这将自动为您设置这些规则...

This will automatically set these rules for you...

items.*.id       => required
items.*.quantity => min:0
