Workflow::Validator::MatchesDateFormat - Ensure a stringified date matches a given pattern
<action name="CreateNews"> <validator name="DateFormat"> <param name="date_format" value="%Y-%m-%d"/> <arg value="$news_post_date"/> </validator> </action>
This validator ensures that a given date string matches a
strptime pattern. The parameter 'date_format' is used to declare the pattern against which the date string must be matched, and the single argument is the date to match.
The 'date_format' pattern is a typical
strptime pattern. See DateTime::Format::Strptime for details.
NOTE: If you pass an empty string (or no string) to this validator it will not throw an error. Why? If you want a value to be defined it is more appropriate to use the 'is_required' attribute of the input field to ensure it has a value.
Also, if you pass a DateTime object to the validator it will not determine whether the date is correct or within a range. As far as it is concerned its job is done.
