Laravel数组验证用于数组中的唯一属性，但不要求表中唯一 [英] Laravel array validation for unique attribute in array but not required to be unique in table

问题描述

我在php中有一个数组.我需要验证数组，以便每个abc_id在数组中都应该是唯一的，但在数据库表中并不需要是唯一的.

I have an array in php. i need to validate array such that each abc_id should be unique in array but not required to be unique in database table.

$validator = Validator::make($request->all(), [
 'tests.*.*.abc_id' => 'should not be same in array' 
 ]);

预先感谢.

推荐答案

您可以使用 distinct laravel array 验证规则.

You can use distinct rule of laravel array validation.

$validator = Validator::make(
          ['products' => 
            ['product_id' => 1, 'quantity' => 5],
            ['product_id' => 1, 'quantity' => 99],
            ['product_id' => 2, 'quantity' => 1],
          ],
          ['products.*.product_id' => 'distinct']
        );

        dd($validator->passes());
