Yii2比较验证器具有空值

Question

I am using a dateTimeComparealidator and i have 4 fields to compare.

1 . earlyOpenDate (should be less than startDate if its not null )

2 . earlyCloseDate (should be greater than earlyOpenDate if its not null )

3 . startDate (should be greater than earlyOpenDate if earlyOpenDate is not null)

4 . endDate (should be greater than endDate )

In this startDate and endDate are mandatory but other 2 are optional.

So my validator doesnt work when i have null value in earlyOpenDate .

When i select any value in startDate it throws error that startDate should be greater than earlyOpenDate .

Is there any way without modifying the validator class to achieve this.

And also when i select the endDate without selecting startDate it displays error message but when i select the startDate after selecting endDate the message it still there until i reselect the date.

It doesnt automatically invoke the validation.

i am using this extension for datetime validation

I also tried to use 'when' validator with condition in yii2 but its not working as expected.

尝试重新执行skipOnEmpty （应为默认值，但扩展名可以重新定义默认值）和/或相关的skipOnError ：

[..., 'skipOnEmpty' => true, 'skipOnError' => ...],
