Question

让我说我提交这份表格：

<form>
    <input type="text" name="emails[]">
    <input type="text" name="emails[]">
    <input type="text" name="emails[]">
    <input type="text" name="emails[]">
    <input type="text" name="emails[]">
</form>

然后我如何验证至少{strong> 1个（所有人）中的$request->emails[]是否已填充？

我已经尝试过-但是它不起作用：

 $request->validate([
     'emails' => 'array|min:1',
     'emails.*' => 'nullable|email',
 ]);

为满足您的要求，您可能需要自定义规则

首先创建一个规则，php artisan make:rule YourRuleName

在YourRuleName.php内

 public function passes($attribute, $value)
 {
     foreach(request()->{$attribute} as $email) {
         // if not null, then just return true. 
         // its assume in arrays some item have values
         if ($email) { // use your own LOGIC here
             return true;
         }
     }

     return false;
 }

然后

 $request->validate([
     'emails' => [new YourRuleName],
 ]);

Laravel请求数组验证
