Laravel 4: validate checkbox at least one
提问by mwafi
I need to validate checkbox array:
我需要验证复选框数组：
<input name="cats[]" type="checkbox" value="1"> sport
<input name="cats[]" type="checkbox" value="2"> music
<input name="cats[]" type="checkbox" value="3"> business
I found "array" validation in documentation:
我在文档中找到了“数组”验证：
Validator::make(
[ 'cats' => Input::get('cats') ],
[ 'cats' => 'array' ]
);
Is there any built-in way to check if at least one item checked? Also, how to check if values submitted match a given list?
是否有任何内置方法来检查是否至少检查了一项？另外，如何检查提交的值是否与给定的列表匹配？

You can use min:valueto validate a numeric value and you can also use it to validate an array's size.
您可以使用 min: value来验证数值，也可以使用它来验证数组的大小。
Validator::make(
[ 'cats' => Input::get('cats') ],
[ 'cats' => 'min:1' ]
);
Examples:
例子：
$validator = Validator::make([
'cats' => ['Boots', 'Mittens', 'Snowball']
], ['cats' => 'min: 1']);
$result = $validator->fails(); // returns false
$validator = Validator::make([
'cats' => ['Boots', 'Mittens', 'Snowball']
], ['cats' => 'min: 2']);
$result = $validator->fails(); // returns false
$validator = Validator::make([
'cats' => ['Boots', 'Mittens', 'Snowball']
], ['cats' => 'min: 4']);
$result = $validator->fails(); // returns true

As of laravel 5 you can just add required rule
从 Laravel 5 开始，您只需添加所需的规则
<input name="cats[]" type="checkbox" value="1"> sport
<input name="cats[]" type="checkbox" value="2"> music
<input name="cats[]" type="checkbox" value="3"> business
// Controller
$rules = $this->validate($request, array('cats'=>'required'));
// will do the work

If you don't mind touching your input data, you could do:
如果您不介意触摸输入数据，则可以执行以下操作：
$data = Input::all();
$data['cats'] = Input::has('cats') ? implode(',',$data['cats']) : null;
$rules = [ 'cats' => 'required|in:foo,bar' ];
$validator = Validator::make($data, $rules);

Bit late to this party but surely just making it "required" will suffice?
这个派对有点晚了，但肯定只是让它“必需”就足够了吗？
public function rules(){
return [
'checkboxarray' => 'required'
];
}
