Workflow::Validator::MUsereContributeWorkflow::Validator::MatchesDateFormat(3)

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

VERSION
       This documentation describes version 1.06 of this package

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

VERSION
       This documentation describes version 1.04 of
       Workflow::Validator::MatchesDateFormat

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
       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.

   METHODS
       _init

       This method initializes the class and the enumerated class.

       It uses "add_enumerated_values" to add the set of values for
       enumeration.

       The primary parameter is value, which should be used to specify the
       either a single value or a reference to array of values to be added.

       validate

       The validator method is the public API. It works with Workflow.

       Based on the initialized Workflow::Validator it validates a provided
       parameter, which should adhere to a predefined date format.

EXCEPTIONS
       ·   You must define a value for 'date_format' in declaration of
	   validator <name>

       ·   The value for 'date_format' must be a simple scalar in declaration
	   of validator <name>

       ·   Date '<date_string>' does not match required pattern <pattern>
