Workflow::Validator::MatchesDateFormat - Ensure a stringified date matches a given pattern
This documentation describes version 1.62 of this package
<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.
strptime
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.
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.
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.
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>
