我对使用MySQL数据库在Laravel中保存输入日期和时间有疑问。我尝试使用dateTime类型将数据保存到数据库中的字段。我为Bootstrap 4使用datetimepicker,其输入格式如ex:10/30/2018 12:00 PM。
错误提示数据丢失

答案 0 :(得分:2)
首先,您应该确切地确定日期如何发布到您的控制器。
dd($request->startFrom);
这样,您可以确保它实际上已被发布。
第二,您使用碳的方式有点长。只需执行以下操作即可。
$date = Carbon::parse($request->startFrom)->format('d-m-Y H:i:s');
这会将您的日期格式化为适合您的数据库的格式。
实际上没有看到错误,我只能猜测这是原因,因此您需要答案。
答案 1 :(得分:0)
在Laravel中,您需要传递格式化的日期:
$: cat tst
#! /bin/env bash
declare -i lines=0 words=0 chars=0
case "$#" in
0) wc ;;
*) for file in $*
do read lines words chars x <<< "$( wc $file )"
echo "$lines $words $chars $file"
done ;;
esac
$: cat foo
hello
world
and
goodbye cruel world!
$: tst < foo
6 6 40
$: tst foo tst
6 6 40 foo
9 38 206 tst
或
public function setStartFromAttribute($value)
{
$this->attributes['start_from'] = $value;
}
