Laravel "At Least One" Field Required Validation
PhpLaravelLaravel 4Php Problem Overview
So I have this form with these fields
{{ Form::open(array('url' => 'user', 'id' => 'user_create_form')) }}
<div class="form-input-element">
<label for="facebook_id">ID Facebook</label>
{{ Form::text('facebook_id', Input::old('facebook_id'), array('placeholder' => 'ID Facebook')) }}
</div>
<div class="form-input-element">
<label for="twitter_id">ID Twitter</label>
{{ Form::text('twitter_id', Input::old('twitter_id'), array('placeholder' => 'ID Twitter')) }}
</div>
<div class="form-input-element">
<label for="instagram_id">ID Instagram</label>
{{ Form::text('instagram_id', Input::old('instagram_id'), array('placeholder' => 'ID Instagram')) }}
</div>
{{ Form::close() }}
I'd like to tell Laravel that at least one of these fields is required. How do I do that using the Validator?
$rules = array(
'facebook_id' => 'required',
'twitter_id' => 'required',
'instagram_id' => 'required',
);
$validator = Validator::make(Input::all(), $rules);
Php Solutions
Solution 1 - Php
Try checking out required_without_all:foo,bar,...
, it looks like that should do it for you. To quote their documentation:
> The field under validation must be present only when the all of the other specified fields are not present.
Example:
$rules = array(
'facebook_id' => 'required_without_all:twitter_id,instagram_id',
'twitter_id' => 'required_without_all:facebook_id,instagram_id',
'instagram_id' => 'required_without_all:facebook_id,twitter_id',
);
$validator = Validator::make(Input::all(), $rules);
Solution 2 - Php
**For automatic validation**
$rules = array(
'facebook_id' => 'required_without_all:twitter_id,instagram_id',
'twitter_id' => 'required_without_all:facebook_id,instagram_id',
'instagram_id' => 'required_without_all:facebook_id,twitter_id',
);
$message = array(
'facebook_id' => 'The facebook field is required when none of twitter / instagram are present.',
'twitter_id' => 'The twitter field is required when none of facebook / instagram are present.',
'instagram_id' => 'The instagram field is required when none of twitter / facebook are present.');
$validator = Validator::make(Input::all(), $rules, $message)->validate();
Solution 3 - Php
use this code i already made it
php artisan make:rule RequiredWithout
use Illuminate\Contracts\Validation\Rule;
class RequiredWithout implements Rule
{
private $without = [];
private $current_attribute = "";
private $no_need = "";
public function __construct($without)
{
if(is_string($without))
{
$this->without = [$without];
}
elseif(is_array($without))
{
$this->without = $without;
}
else
throw new \Exception('$without must be array or string');
}
public function passes($attribute, $value)
{
$this->current_attribute = $attribute;
$requests = request()->all();
foreach ($this->without as $WO_i)
{
if(array_key_exists($WO_i, $requests))
{
$this->no_need = $WO_i;
return false;
}
}
return true;
}
public function message()
{
return "the $this->current_attribute Field and $this->no_need Shouldn't be Exist in this request together";
}
}
and then in the controller use this
'country_id' => ['nullable', 'exists:countries,id', new ValidCountryID(), new RequiredWithout('country_code')],
'country_code' => ['nullable', 'exists:countries,IsoCountryCode', new ValidCountryID(), new RequiredWithout('country_id')],
