如何使用laravel验证验证并显示至少一个下拉列表

Question

I have a form that form has two dropdown. If I submit form I need to validate and show at-least one dropdown required. I have added some functionality but not working.

create.blade.php

<select class="form-control" id="user" name="user">
     <option value="0"> select user </option>
     <option value="1"> jane </option>
     <option value="2"> peter </option>
</select>

<select class="form-control" id="email" name="email">
     <option value="0"> select email</option>
     <option value="1"> [e-mail] </option>
     <option value="2"> [e-mail] </option>
</select>

CreateRequest.php

public function rules()
{
   $rules = [
             'user' => 'required_without_all:email|not_in:0',
             'email' => 'required_without_all:user|not_in:0',
            ];
   return $rules;
}

Answer 1

Instead of required_without_all use required_without. The former accepts a list of fields, whereas you only need one.

Also, skip using value '0' for your select placeholder, and then remove that from your validation.

For example:

    <select class="form-control" id="user" name="user" placeholder="Select user">
         <option value=""> select user </option>
         <option value="1"> jane </option>
         <option value="2"> peter </option>
    </select>

and the validation:

'user' => 'required_without:email',
