Php 获取最多两天的前10个常用表格实体?
这是我的mySql表“listazelja”: 我想在我的控制器中获得标题中提到的代码:Php 获取最多两天的前10个常用表格实体?,php,laravel,php-carbon,Php,Laravel,Php Carbon,这是我的mySql表“listazelja”: 我想在我的控制器中获得标题中提到的代码: <?php namespace App\Http\Controllers; use App\ListaZelja; use Carbon\Carbon; use Illuminate\Http\Request; use Illuminate\Support\Facades\DB; class GlazbeniController extends Controller { public
<?php
namespace App\Http\Controllers;
use App\ListaZelja;
use Carbon\Carbon;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class GlazbeniController extends Controller
{
public function listazelja(){
$sada = Carbon::now();
$listaZelja = DB::table('listazelja')->orderBy('zapis_count','desc')->select(DB::raw('count(*) as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->having($sada->diffInHours(Carbon::createFromFormat('Y-m-d H-m-s', 'created_at')) <= 48)
->take(10)->get();
return view('pregledajlistuzelja',compact('listaZelja'));
}
}
试试这个
$maxhours = Carbon::now()->subHours(48)->toDateTimeString();
$listaZelja = DB::table('listazelja')
->orderBy('zapis_count','desc')
->select(DB::raw('count(*) as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->having('created_at' <= maxhours)
->take(10)->get();
$maxhours=Carbon::now()->subHours(48)->toDateTimeString();
$listaZelja=DB::table('listaZelja')
->orderBy('zapis_count','desc')
->选择(DB::raw('count(*)as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->有('created_at'take(10)->get();

我想你的问题是:
$twoDaysOldDate = date("Y-m-d",strtotime('now -48 hours'));
$listaZelja = DB::table('listazelja')
->orderBy('zapis_count','desc')
->select(DB::raw('count(*) as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->whereDate('created_at', '<=', $twoDaysOldDate)
->take(10)
->get();
$twoDaysOldDate=日期(“Y-m-d”,标准时间(“现在-48小时”);
$listaZelja=DB::table('listaZelja')
->orderBy('zapis_count','desc')
->选择(DB::raw('count(*)as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->whereDate('created_at',”我认为您的查询如下:
$twoDaysOldDate = date("Y-m-d",strtotime('now -48 hours'));
$listaZelja = DB::table('listazelja')
->orderBy('zapis_count','desc')
->select(DB::raw('count(*) as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->whereDate('created_at', '<=', $twoDaysOldDate)
->take(10)
->get();
$twoDaysOldDate=日期(“Y-m-d”,标准时间(“现在-48小时”);
$listaZelja=DB::table('listaZelja')
->orderBy('zapis_count','desc')
->选择(DB::raw('count(*)as zapis_count'),'zapis_id')
->groupBy('zapis_id')
->whereDate('created_at','我认为'created_at'只是作为字符串传递,因为您在$sada.PS内调用它。这就是我讨厌框架的原因。请尝试在Carbon::createFromFormat($format,$time,$tz)中使用Mysql NOW()函数和INTERVAL或TiMEDIFF
第二个参数必须是$time
但您正在传递一个值为created_at
的字符串。从Carbon
docCarbon::createFromFormat('Y-m-d H',1975-05-21 22')->toDateTimeString()中提取;//1975-05-21 22:00:00
@EddyTheDove的答案似乎没有问题,我认为“created_at”只是作为字符串传递,因为您在$sada.PS内调用它。这就是我讨厌框架的原因。请尝试在Carbon::createFromFormat($format,$time,$tz)中使用Mysql NOW()函数和INTERVAL或TiMEDIFF
第二个参数必须是$time
,但您正在传递一个值为created_的字符串。Carbon
docCarbon::createFromFormat('Y-m-d H','1975-05-21 22')->toDateTimeString();/1975-05-21 22:00:00
@eddystedove的答案似乎没有“$”的意思在maxhours,其他东西也不起作用。但是,无论如何,thanx。:)除了在maxhours缺少“$”之外,其他东西也不起作用。但是,thanx无论如何。:)
