只获取今天在幼虫期创建的记录

如何使用 created_at字段只获取今天创建的记录,而不是其他日期或时间?

我在想一个 ->where('created_at', '>=', Carbon::now()),但我不知道这将工作。

You can use

whereRaw('date(created_at) = curdate()')

if the timezone is not a concern or

whereRaw('date(created_at) = ?', [Carbon::now()->format('Y-m-d')] )

otherwise.

Since the created_at field is a timestamp, you need to get only the date part of it and ignore the time part.

Use Mysql default CURDATE function to get all the records of the day.

    $records = DB::table('users')->select(DB::raw('*'))
->whereRaw('Date(created_at) = CURDATE()')->get();
dd($record);

Note

The difference between Carbon::now vs Carbon::today is just time.

e.g

Date printed through Carbon::now will look like something:

2018-06-26 07:39:10.804786 UTC (+00:00)

While with Carbon::today:

2018-06-26 00:00:00.0 UTC (+00:00)

To get the only records created today with now can be fetched as:

Post::whereDate('created_at', Carbon::now()->format('m/d/Y'))->get();

while with today:

Post::whereDate('created_at', Carbon::today())->get();

UPDATE

As of laravel 5.3, We have default where clause whereDate / whereMonth / whereDay / whereYear

$users = User::whereDate('created_at', DB::raw('CURDATE()'))->get();

OR with DB facade

$users = DB::table('users')->whereDate('created_at', DB::raw('CURDATE()'))->get();

Usage of the above listed where clauses

$users = User::whereMonth('created_at', date('m'))->get();
//or you could also just use $carbon = \Carbon\Carbon::now(); $carbon->month;
//select * from `users` where month(`created_at`) = "04"
$users = User::whereDay('created_at', date('d'))->get();
//or you could also just use $carbon = \Carbon\Carbon::now(); $carbon->day;
//select * from `users` where day(`created_at`) = "03"
$users = User::whereYear('created_at', date('Y'))->get();
//or you could also just use $carbon = \Carbon\Carbon::now(); $carbon->year;
//select * from `users` where year(`created_at`) = "2017"

Query Builder Docs

$today = Carbon\Carbon::now()->format('Y-m-d').'%';
->where('created_at', 'like', $today);

Hope it will help you

with carbon:

return $model->where('created_at', '>=', \Carbon::today()->toDateString());

without carbon:

return $model->where('created_at', '>=', date('Y-m-d').' 00:00:00');

If you are using Carbon (and you should, it's awesome!) with Laravel, you can simply do the following:

->where('created_at', '>=', Carbon::today())

Besides now() and today(), you can also use yesterday() and tomorrow() and then use the following:

  • startOfDay()/endOfDay()
  • startOfWeek()/endOfWeek()
  • startOfMonth()/endOfMonth()
  • startOfYear()/endOfYear()
  • startOfDecade()/endOfDecade()
  • startOfCentury()/endOfCentury()

For Laravel 5.6+ users, you can just do

$posts = Post::whereDate('created_at', Carbon::today())->get();

No need to use Carbon::today because laravel uses function now() instead as a helper function

So to get any records that have been created today you can use the below code:

Model::whereDay('created_at', now()->day)->get();

You need to use whereDate so created_at will be converted to date.

$records = User::where('created_at' = CURDATE())->GET()); print($records);

Laravel ^5.6 - Query Scopes

For readability purposes i use query scope, makes my code more declarative.

scope query

namespace App\Models;


use Illuminate\Support\Carbon;
use Illuminate\Database\Eloquent\Model;


class MyModel extends Model
{
// ...


/**
* Scope a query to only include today's entries.
*
* @param  \Illuminate\Database\Eloquent\Builder  $query
* @return \Illuminate\Database\Eloquent\Builder
*/
public function scopeCreatedToday($query)
{
return $query->where('created_at', '>=', Carbon::today());
}


// ...
}

example of usage

MyModel::createdToday()->get()

SQL generated

Sql      : select * from "my_models" where "created_at" >= ?


Bindings : ["2019-10-22T00:00:00.000000Z"]

I’ve seen people doing it with raw queries, like this:

$q->where(DB::raw("DATE(created_at) = '".date('Y-m-d')."'"));

Or without raw queries by datetime, like this:

$q->where('created_at', '>=', date('Y-m-d').' 00:00:00'));

Luckily, Laravel Query Builder offers a more Eloquent solution:

$q->whereDate('created_at', '=', date('Y-m-d'));

Or, of course, instead of PHP date() you can use Carbon:

$q->whereDate('created_at', '=', Carbon::today()->toDateString());

It’s not only whereDate. There are three more useful functions to filter out dates:

$q->whereDay('created_at', '=', date('d'));
$q->whereMonth('created_at', '=', date('m'));
$q->whereYear('created_at', '=', date('Y'));

Below code worked for me

  $today_start = Carbon::now()->format('Y-m-d 00:00:00');
$today_end = Carbon::now()->format('Y-m-d 23:59:59');


$start_activity = MarketingActivity::whereBetween('created_at', [$today_start, $today_end])
->orderBy('id', 'ASC')->limit(1)->get();

simple solution:

->where('created_at', 'like', date("Y-m-d")."%");

Carbon::today() will return something like this: 2021-08-06T00:00:00.000000Z, so using Model::where('created_at', Carbon::today()) will only return records created at exactly 12:00 am current date.

Use Model::where('created_at', '>=', Carbon::today()) instead

I use laravel9 on 22 Apr 2022 how I get the "today" record is :

  1. I have edit "config/app.php" on the "timezone" (about line 72 ) I have set it to my timezone which is "Asia/Bangkok"

  2. my query code I have is :

    $get = User::whereDate("created_at","=",date("Y-m-d",time() ) )->get();

will get the field that created today.

I don't know if this a correct way or it another bad code but as long as it work for me I will be okay.

Post::whereDate('created_at', '=', date('Y-m-d'))->get();

It will give you All the posts created today !!!!! if you use time with this you will get posts of that particular time not of today

laravel 8

 $VisitorEntryStatusDateCurrent = VisitorEntry::whereDate('created_at', Carbon::today())->get();
