像许多其他人一样,我也为此苦苦挣扎,很好地显示网格不是问题,但在本地化日期时间中过滤是!所以我创建了自己的格式化程序,在search()
我的模型函数中使用它(当将搜索参数传递给时compare()
),它就像一个魅力。我现在可以过滤任何本地化中的日期/日期时间字段(我使用荷兰语):
"30-12-2018" becomes "2018-12-30"
">30-12-2018" becomes ">2018-12-30"
"30-12-2018 23:59:49" becomes "2018-12-30 23:59:49"
">=30-12-2018 23:59:49" becomes ">=2018-12-30 23:59:49"
我的本地化:
// dateFormat['short'] = 'dd-MM-yyyy'
// timeFormat['medium'] = 'HH:mm:ss'
Yii::app()->format->datetimeFormat = strtr(Yii::app()->locale->dateTimeFormat,
array("{0}" => Yii::app()->locale->getTimeFormat('medium'),
"{1}" => Yii::app()->locale->getDateFormat('short')));
Yii::app()->format->dateFormat = 'short';
Yii::app()->format->timeFormat = 'medium';
我的 CGridView 包含以下日期时间列:
'mutation_date_time:dateTime'
和(一个片段)我自己的格式化程序有一些方便的功能:
class Formatter extends CLocalizedFormatter
{
public function formatWithoutSearchOperator($value)
{
// This snippet is taken from CDbCriteria->compare()
if(preg_match('/^(?:\s*(<>|<=|>=|<|>|=))?(.*)$/',$value,$matches))
{
$value=$matches[2];
$op=$matches[1];
}
else
$op='';
return $value;
}
public function formatOnlySearchOperator($value)
{
// This snippet is taken from CDbCriteria->compare()
if(preg_match('/^(?:\s*(<>|<=|>=|<|>|=))?(.*)$/',$value,$matches))
{
$value=$matches[2];
$op=$matches[1];
}
else
$op='';
return $op;
}
/*
* Format a localized datetime back to a database datetime (Y-m-d H:i:s).
* If a comparison operator is given, it is preserved. So strip it if you need to save the date in the database.
* If no time given, it's also not returned (MySQL database appends '00:00:00' as time to it upon saving).
* With this function the following localized datetimes just work like the stock datetime filters:
* - "30-12-2018" becomes "2018-12-30"
* - "30-12-2018 " becomes "1970-01-01" (note the extra space in input)
* - ">30-12-2018" becomes ">2018-12-30"
* - "30-12-2018 23:59:49" becomes "2018-12-30 23:59:49"
* - ">=30-12-2018 23:59:49" becomes ">=2018-12-30 23:59:49"
*
* For save() and afterFind() integration see:
* https://github.com/YetOpen/i18n-datetime-behavior

public function formatToDatabaseDatetime($value)
{
// get the comparison operator from the string:
$comparator = $this->onlySearchOperator($value);
// get the datetime without the comparison operator:
$datetime = $this->withoutSearchOperator($value);
// parse the given datetime according to the locale format to a timestamp
$datetime_parsed = CDateTimeParser::parse(
$datetime,
strtr(
Yii::app()->locale->datetimeFormat,
array(
"{0}" => Yii::app()->locale->getTimeFormat(Yii::app()->format->timeFormat),
"{1}" => Yii::app()->locale->getDateFormat(Yii::app()->format->dateFormat)
)
)
);
// if its not a valid date AND time, check if it can be parsed to a date only:
if($datetime_parsed === false)
{
$date_parsed = CDateTimeParser::parse(
$datetime,
Yii::app()->locale->getDateFormat(Yii::app()->format->dateFormat)
);
}
// If no time part given, also output only the date
if($datetime_parsed===false)
{
$transformed = date(
'Y-m-d',
$date_parsed
);
}
else
{
$transformed = date(
'Y-m-d H:i:s',
$datetime_parsed
);
}
return $comparator . $transformed;
}
}
在search()
我的 CActiveRecord 模型的函数中,我使用以下内容将本地化的日期时间与数据库中的记录进行比较:
$criteria->compare('mutation_date_time',Yii::app()->format->toDatabaseDateTime(trim($this->mutation_date_time)),true);
请注意trim()
,这是设计使然(请参阅函数描述 formatToDatabaseDateTime())。
直接以正确的数据库格式过滤的一大区别:无效日期转换为“1970-01-01”!
我非常感谢反馈,我真的希望我的代码可以帮助别人!
