我有一个名为' ical'它包含一个url,但我想要做的是运行一个函数使用url下载文件,但是当field为空时忽略该行。它的作用是它为每一行下载一个文件,如果有一个网址,它填入的数据是正确的,但是当字段为空时它下载了一个文件,但当然它是空的,而是我如果是空的话,只想完全忽略该行。
以下是代码:
<?php
namespace App\Console\Commands;
use App\Entity;
use Illuminate\Console\Command;
use Ixudra\Curl\Facades\Curl;
class DownloadIcal extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'ical:download';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Download all ICAL files from ical field in businesses database';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
$entities = Entity::pluck('ical', 'id');
foreach ( $entities as $entityID => $entityIcal ) {
$response = Curl::to($entityIcal)
->download('public/ical/'.$entityID.'.ics');
$this->info("ICal Retrieved");
}
}
}

您所要做的就是在循环中使用if
并检查值是否为空或为空。
$entities = Entity::pluck('ical', 'id');
foreach ( $entities as $entityID => $entityIcal )
{
if ( !is_null($entityIcal) and !empty($entityIcal))
{
$response = Curl::to($entityIcal)
->download('public/ical/'.$entityID.'.ics');
$this->info("ICal Retrieved");
}
}
