NAME

Workflow::Validator::MatchesDateFormat - Ensure a stringified date matches a given pattern

SYNOPSIS

 <action name="CreateNews">
   <validator name="DateFormat">
      <param name="date_format" value="%Y-%m-%d"/>
      <arg value="$news_post_date"/>
   </validator>
 </action>

DESCRIPTION

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 the DateTime::Format::Strptime manpage 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.
