How to validate a form field based on the data from another one? - Laravel 6

问题

我有一个包含以下字段的表单：

  • n_census（提供有关城镇或城市的总人口信息）
  • n_participants（根据n_census提供选举过程中参与者的数量信息）

我想要根据n_census验证n_participants，因为不可能有比n_census更多的n_participants。

我用于验证这两个字段（以及其他与此问题不相关的字段）的代码如下：

  1. <!-- language: php -->
  2. protected function validator(array $data)
  3. {
  4.     $customMessages = [
  5.         'required' => ':attribute 是必填项',
  6.         'min' => ':attribute 至少需要 :min 个字符',
  7.         'max' => ':attribute 最多可以有 :max 个字符',
  8.         'string' => ':attribute 必须是一个字符串',
  9.         'int' => ':attribute 必须是一个整数',
  10.         'email' => ':attribute 是一个电子邮件地址',
  11.         'confirmed' => '你未确认电子邮件'
  12.     ];
  14.     return Validator::make($data, [
  15.         'name' => ['required', 'string', 'max:255'],
  16.         'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
  17.         'password' => ['required', 'string', 'min:8', 'confirmed'],
  18.         'dni' => ['required', 'string', 'min:9', 'max:9'],
  19.         'surname1' => ['required', 'string', 'max:50'],
  20.         'surname2' => ['required', 'string', 'max:50'],
  21.         'v1' => ['required', 'string', 'max: 100'],
  22.         'v2' => ['required', 'string', 'max: 100'],
  23.         'district' => ['required', 'int'],
  24.         'section' => ['required', 'int'],
  25.         'chair' => ['required', 'string'],
  26.         'municipality' => ['required'],
  27.         'province' => ['required'],
  28.         'n_census' => ['required', 'int'],
  29.         'n_participants' => ['required', 'int', 'max: 50']
  30.     ], $customMessages);
  31. }

是否可以使用Validator::make() 来实现这个目标？

英文:

I have a form which contains the following fields:

  • n_census (provides information about the total population from a town or city)
  • n_participants (provides information about the number of participants in an election process according to n_census)

I would like to validate n_participants according to n_census because it's not possible to have more n_participants than n_census.

The code I use to validate both fields (and others I have but not relevant for this issue) is:

<!-- language: php -->

  1. protected function validator(array $data)
  2. {
  3.     $customMessages = [
  4.         &#39;required&#39; =&gt; &#39;:attribute es obligatori&#39;,
  5.         &#39;min&#39; =&gt; &#39;:attribute cal que siga, com a m&#237;nim, :min caracters&#39;,
  6.         &#39;max&#39; =&gt; &#39;:attribute cal que siga, com a m&#224;xim, :max caracters&#39;,
  7.         &#39;string&#39; =&gt; &#39;:attribute cal que siga una cadena de caracters&#39;,
  8.         &#39;int&#39; =&gt; &#39;:attribute cal que siga un enter&#39;,
  9.         &#39;email&#39; =&gt; &#39;:attribute es un email&#39;,
  10.         &#39;confirmed&#39; =&gt; &#39;No has confirmat el correu electr&#242;nic&#39;
  11.     ];
  13.     return Validator::make($data, [
  14.         &#39;name&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;max:255&#39;],
  15.         &#39;email&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;email&#39;, &#39;max:255&#39;, &#39;unique:users&#39;],
  16.         &#39;password&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;min:8&#39;, &#39;confirmed&#39;],
  17.         &#39;dni&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;min:9&#39;, &#39;max:9&#39;],
  18.         &#39;surname1&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;max:50&#39;],
  19.         &#39;surname2&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;max:50&#39;],
  20.         &#39;v1&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;max: 100&#39;],
  21.         &#39;v2&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;max: 100&#39;],
  22.         &#39;district&#39; =&gt; [&#39;required&#39;, &#39;int&#39;],
  23.         &#39;section&#39; =&gt; [&#39;required&#39;, &#39;int&#39;],
  24.         &#39;chair&#39; =&gt; [&#39;required&#39;, &#39;string&#39;],
  25.         &#39;municipality&#39; =&gt; [&#39;required&#39;],
  26.         &#39;province&#39; =&gt; [&#39;required&#39;],
  27.         &#39;n_census&#39; =&gt; [&#39;required&#39;, &#39;int&#39;],
  28.         &#39;n_participants&#39; =&gt; [&#39;required&#39;, &#39;int&#39;, &#39;max: 50&#39;]
  29.     ], $customMessages);
  30. }

Is it possible to use Validator::make() to do that?

答案1

得分: 2

  1. return Validator::make($data, [
  2.     'name' => ['required', 'string', 'max:255'],
  3.     'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],

  5.             &#39;dni&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;min:9&#39;, &#39;max:9&#39;],
  6.             &#39;surname1&#39; =&gt; [&#39;required&#39;, &#39;string&#39;, &#39;max:50&#39;],

  10.             &#39;district&#39; =&gt; [&#39;required&#39;, &#39;int&#39;],
  11.             &#39;section&#39; =&gt; [&#39;required&#39;, &#39;int&#39;],
  12.             &#39;chair&#39; =&gt; [&#39;required&#39;, &#39;string&#39;],
  13.             &#39;municipality&#39; =&gt;  [&#39;required&#39;],
  14.             &#39;province&#39; =&gt;  [&#39;required&#39;],
  15.             &#39;n_participants&#39; =&gt; [&#39;required&#39;, &#39;int&#39;, &#39;max: 50&#39;],
  16.             &#39;n_census&#39; =&gt; [&#39;required&#39;, &#39;int&#39;,&#39;gte:n_participants&#39;],
