Question

在验证方法中，我有以下内容：

$this->validate($request, ['test_date' => 'required|unique:test_db']);

test_date中的test_db存储为unix时间。提交表单后，我会在$request->get('test_date')

中获得mm/dd/Y

唯一验证不起作用，因为我在mm/dd/Y中得到的日期与db（unix时间）不同。

如何在此验证中使其独一无二？

在请求中添加字段：Laravel is there a way to add values to a request array

更新： 您可以使用offsetSet方法更新现有字段：

//get date from request
$date = $request->get('test_date');

//add the converted date to request
$request->request->add(['new_date_field'=> DateTime::createFromFormat('m/d/Y', $date)->getTimestamp()]);

//validate the updated date field
$this->validate($request, ['new_date_field' => 'required|unique:test_db']);

更新请求字段： Modify request field value before saving in Laravel 5

Answer 2

我认为如果你改变日期格式，那么一切都会好的，所以试试这个：

$date = $request->get('test_date');

$newDate = date('d-m-Y', strtotime($date ));

在验证中使用此$newDate。

Answer 3

Laravel提供名为Accessors和mutators的功能。

Accessor和mutators允许您在模型实例上检索或设置Eloquent属性值时设置其格式。

有关详细信息，请访问：https://laravel.com/docs/5.5/eloquent-mutators#accessors-and-mutators

希望这会对你有所帮助。
