Laravel Carbon format date
提问by Dev.Wol
I am posting via ajax a date from my form which is in the format.
我通过ajax从我的表单中发布了一个日期格式。
27/07/2016
27/07/2016
When it hits my controller I convert the format to Y-m-d as It is store in my database like that.
当它到达我的控制器时，我将格式转换为 Ymd，因为它像这样存储在我的数据库中。
However I'm getting the following error:
但是我收到以下错误：
DateTime::__construct(): Failed to parse time string (27/07/2016) at position 0 (2): Unexpected character
DateTime::__construct(): 无法解析位置 0 (2) 处的时间字符串 (27/07/2016)：意外字符
My controller
我的控制器
public function call(Request $request)
{
return Company->expenses()->where('date_expense', Carbon::parse($request->start)->format('Y-m-d'))->get();
}
On my expenses model I have the following defined as dates:
在我的费用模型中，我将以下定义为日期：
protected $dates = ['date_expense'];

Use Carbon's Carbon::createFromFormat($format, $time, $tz);method:
使用碳的Carbon::createFromFormat($format, $time, $tz);方法：
$start = Carbon::createFromFormat('d/m/Y', $request->start);
return Company->expenses()->where('date_expense', $start)->get();
By the way, there is no need to further format the date as Laravel knows how to handle Carbon objects and will do that automatically for you behind the scenes.
顺便说一句，没有必要进一步格式化日期，因为 Laravel 知道如何处理 Carbon 对象，并且会在幕后自动为您完成。

Use
用
Carbon::createFromFormat('d/m/Y', $request->start)->format('d/m/Y')
You have to change your code with this

If your laravel framework version is 5.0+
you can check by php artisan -V
如果你的 Laravel 框架版本是 5.0+ 你可以检查 php artisan -V
mine is Laravel Framework 5.4.19you can make a reference from laravel document https://laravel.com/docs/5.4/eloquent-mutators#date-mutators
我的是Laravel Framework 5.4.19你可以从 laravel 文档https://laravel.com/docs/5.4/eloquent-mutators#date-mutators做一个参考
The following is an example:
下面是一个例子：
if your laravel Framework doesn't contains Carbon ,you can run
composer require nesbot/carbonat your model such as Post model
如果你的 laravel 框架不包含 Carbon ，你可以运行
composer require nesbot/carbon在您的模型上，例如 Post 模型
class Post extends Model`
{
protected $fillable = ["title","body"];`
protected $dates = [`
'created_at',`
'updated_at',`
'deleted_at'`
];
}
- use tinker to add a post
open terminal under project directory
run
php artisan tinker
- 使用 tinker 在项目目录 run 下添加一个 post open 终端
php artisan tinker
App\Post::create("title"=>"This is Title","body"=>"this is body")
App\Post::create("title"=>"This is Title","body"=>"this is body")
and then you can get lastest created post's created_at by Carbon
然后你可以得到最新创建的帖子的 created_at by Carbon
by App\Post::latest()->get()->created_at->diffForHumans()
经过 App\Post::latest()->get()->created_at->diffForHumans()
you can also use same method in blade like this
{{ $post->created_at->diffForHumans() }}
您也可以像这样在刀片中使用相同的方法
{{ $post->created_at->diffForHumans() }}
the Carbon document url is as followed: http://carbon.nesbot.com/docs/
Carbon 文档 url 如下：http: //carbon.nesbot.com/docs/
