Laravel"不允许'封闭'序列化"

Question

当我在Laravel中存储数据集时,我有时会遇到此错误并且没有找到解决方案.

Serialization of 'Closure' is not allowed
Open: ./vendor/laravel/framework/src/Illuminate/Session/Store.php
     */
    public function save()
    {
        $this->addBagDataToSession();

        $this->ageFlashData();

        $this->handler->write($this->getId(), serialize($this->attributes));

        $this->started = false;

以下是发生错误时调用的函数:

public function store()
    {

        $data = Input::all();
        $validator = array('first_name' =>'required', 'last_name' => 'required', 'email' => 'email|required_without:phone', 'phone' => 'numeric|size:10|required_without:email', 'address' => 'required');
        $validate = Validator::make($data, $validator);
        if($validate->fails()){
            return Redirect::back()->with('message', $validate);
        } else {
            $customer = new Customer;
            foreach (Input::all() as $field => $value) {
                if($field == '_token') continue;
                $customer->$field = $value;
            }
            $customer->save();
            return View::make('admin/customers/show')->withcustomer($customer);
        }
    }

导致此序列化错误的原因是什么？

Answer 1

只需更换以下行:

return Redirect::back()->with('message', $validate);

有了这个:

return Redirect::back()->withErrors($validate);

此外,您可以使用类似的东西(使用旧值重新填充表单):

return Redirect::back()->withErrors($validate)->withInput();

在view你可以使用$errors变量获得错误信息,所以如果你使用$errors->all(),你会得到错误信息的数组,让你可以尝试这样一个特定的错误:

{{ $errors->first('email') }} // Print (echo) the first error message for email field

另外,在以下行中:

return View::make('admin/customers/show')->withcustomer($customer);

您需要将动态方法更改为withCustomer不withcustomer,因此您将能够访问$customer您的变量view.
