Question

在我的控制器中，我使用验证器检查唯一的company_name，但在传递已存在的公司名称时显示错误。正好与其他文本一起使用。

$input['company_name'] = Input::get('company_name');
        $rules = array('company_name' => "unique:subcontractors,company_name,$id");
        $validator_cn = Validator::make($input, $rules);
        if ($validator_cn->fails()) { 
            return Redirect::back()->with('alert-danger',"Company Name already exist.")->withInput();
        }

给出错误＆＃34; helpers.php第519行：＆＃34;

htmlspecialchars() expects parameter 1 to be string, array given

Answer 1

试试这段代码。这有帮助！

$input['company_name'] = Input::get('company_name');
            $rules = array(
                'company_name' => 'unique:subcontractors,company_name,'.$id
            );
            $validator_cn = Validator::make($input, $rules);
            if ($validator_cn->fails()) {
                return Redirect::back()->with(['alert-danger'=>"Company Name already exist."])->withInput();
            }

Answer 2

只有在$id有某些值时才需要添加"unique:subcontractors,company_name".($id ? ",$id" : '')，否则不要像

那样添加它

$input['company_name'] = Input::get('company_name');
$rules = array('company_name' => "unique:subcontractors,company_name".($id ? ",$id" : ''));
$validator_cn = Validator::make($input, $rules);
if ($validator_cn->fails()) { 
   return Redirect::back()->with('alert-danger',"Company Name already exist.")->withInput();
}

完整代码，

unique:table,column,except,idColumn

根据unique syntax（id），如果您想使用"unique:subcontractors,company_name".($id ? ",id,$id" : '')，那么请使用，
