具有多个值的 required_if laravel

Required_if laravel with multiple value(具有多个值的 required_if laravel)

问题描述

我有一个这样的下拉菜单:

I have a dropdown menu like this:

<select name="selection">
   <option value="1">Option 1</option>
   <option value="2">Option 2</option>
   <option value="3">Option 3</option>
</select>
<input type="text" name="stext">

我想要在 Laravel 中的以下内容:

I want the following in laravel:

public static myfunction(){
   $input = Input::only('selection','stext');
   $rule = array(
      'selection' => 'required',
      'stext' => 'required_if:selection,2,3',
   );
   $validate = Validator::make($input,$rule);
}

但是如果我选择选项 1，stext 仍然是必需的.为什么?我该如何解决?

But if I select option 1, stext is still required. Why? How can I fix it?

推荐答案

正如 LePhleg answer 所指出的，此验证有一个最好的语法:

As pointed out by LePhleg answer, there is a nicest syntax for this validation:

$rule = array(
  'selection' => 'required',
  'stext' => 'required_if:selection,2,3,
);

下面的旧答案:

我认为 require_if 验证每次只接受一个值.尝试更改您的验证代码如下:

I think that the require_if validation accept only one value per time. Try to change your validation code as below:

$rule = array(
  'selection' => 'required',
  'stext' => 'required_if:selection,2|required_if:selection,3',
);

检查 LePhleg 的答案，更干净.在回答不可能的时候，只检查问题，他正在使用相同的方法但没有奏效.

Check LePhleg answer, is more cleaner. At the time of the answer that was not possible, just check the question, he was using the same method but not worked.
