Zend Framework: Zend_Validate_PostCode Component Proposal

Table of Contents

1. Overview

Zend_Validate_PostCode is a compnent which will validate if a given string conforms a post code from any region within the world.

2. References

• Wikipedia-Postal code

3. Component Requirements, Constraints, and Acceptance Criteria

• This component will support postal codes from all countries
• This component will only validate
• This component will not change the notation of the input
• This component will not 100% detect if a given postal code exists or not

4. Dependencies on Other Framework Components

• Zend_Exception
• Zend_Locale

5. Theory of Operation

This component uses Zend_Locale to get the postal code informations for all known countries. These are then used to detect if the given input is a postal code or not. This component can not detect if a given postal code exists or not. It only checks if a given input can be a postal code, if the notation conforms, or not.
