問題描述

我想制作一個(gè) Laravel 驗(yàn)證器來驗(yàn)證數(shù)組內(nèi)的未命名數(shù)組 ( 0,1,2,3 ) 內(nèi)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

所以我的數(shù)組就像

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 *
  ]);

推薦答案

Laravel 5.2

現(xiàn)在支持問題中的語法

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

Laravel 5.1

首先使用您的所有其他規(guī)則創(chuàng)建驗(yàn)證器.對(duì)項(xiàng)目使用 array 規(guī)則

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 方法將一組規(guī)則應(yīng)用于 items 數(shù)組中的每個(gè)項(xiàng)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', 
]);

這將自動(dòng)為您設(shè)置這些規(guī)則...

This will automatically set these rules for you...

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