Laravel excel maatwebsite 3.1 导入,excel 单元格 returns 中的日期列为未知格式数字。如何解决这个问题?
Laravel excel maatwebsite 3.1 import, date column in excel cell returns as unknown format number. How to solve this?
通过使用Maatwebsite/Laravel-Excel 3.1 版导入excel sheet,这里我遇到了 excel sheet [=19] 的问题日期时间列=] 未知数。如何解决这个问题?示例:导入时将单元格值“29/07/1989”和 returns 视为“32178”。
The numbers come from excel itself, dates stored in excel as numeric
values. http://www.cpearson.com/excel/datetime.htm
For Laravel framework 5.6 and maatwebsite/excel package version 3.1,
to convert date from excel numbers to normal date format, this
function
PhpOffice\PhpSpreadsheet\Shared\Date::excelToDateTimeObject($dateFromExcel)
can be used. It accepts integer(excel date) and returns DateTime
object.

已解决!这是我用来解决问题的代码:
Carbon\Carbon::instance(\PhpOffice\PhpSpreadsheet\Shared\Date::excelToDateTimeObject($value));
我尝试了上述解决方案,但总是遇到 non-numeric 值错误
我设法使用
解决了这个问题
$date = intval($row['value']);
\PhpOffice\PhpSpreadsheet\Shared\Date::excelToDateTimeObject($date)->format('d/m/Y')
那个“未知数”是一个 excel 时间戳,这样它就可以在内部存储日期和时间数据。
例如:
123213.0: it's just a date
213233.1233: is a date and time
0.1233: it's one hour
如果您可以映射单元格并且您知道哪一列将始终具有日期/时间/日期时间,您可以使用映射单元格或手动转换它,请参阅:
否则,如果您的需求涉及动态解析日期时间字段,我已经编写了一个方法,负责自动检测该值是否为动态日期时间(无论您是否知道其中是否有日期时间)列)或者我已经尝试了各种数据类型并且工作正常

@skyrem-brilliant 的回答,我是这样解决的:
<?php

public function rules(): array

成功了,验证通过了。
简单的使用这个函数来存储日期。
use PhpOffice\PhpSpreadsheet\Shared;
public function collection(Collection $collection)
{
$errors = $this->validateBulk($collection);
if (!empty($errors)) {
return;
}
$holidays = [];
foreach ($collection as $col) {
Validator::make($col->toArray(), $this->rules())->validate();
$holidays[] = [
'title' => $col['title'],
'holiday_date' => Date::excelToDateTimeObject($col['holiday_date'])
->format('y-m-d'),
'holiday_year' => Date::excelToDateTimeObject($col['holiday_date'])
->format('y'),
];
$this->rows++;
}
Holidays::insert($holidays);
}
