问题汇总
1、问题:导出文件提示file_put_contents(): Filename cannot be empty

解决方案:修改config/excel.php文件中local_path的值为storage文件夹路径
'local_path' => storage_path(),//sys_get_temp_dir(),
2、导入中日期变为数字
原因是导入的时候读取的实际是这个日期的常规格式,意思是从1900-01-01到这个日期一共过去了多少天。
解决方案:
$date = $row['日期'];
$d = 25569;
$t = 24 * 60 * 60;
$at = gmdate('Y-m-d H:i:s', ($date - $d) * $t);3、导入含有多个sheet时报错Start row (2) is beyond highest row (1)
导入类里use一下WithMultipleSheets
<?php
namespace App\Helper\Excel;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
use Maatwebsite\Excel\Concerns\WithColumnFormatting;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;
class Import implements ToCollection, WithHeadingRow, WithMultipleSheets
{
public function collection(Collection $rows)
{
}
public function sheets(): array
{
return [
0 => new static,
];
}
}
