Using a Zend_Config Object

All Zend_Form classes are configurable using Zend_Config; you can either pass a Zend_Config object to the constructor or pass it in with setConfig(). Let's look at how we might create the above form using an INI file. First, let's follow the recommendations, and place our configurations into sections reflecting the release location, and focus on the 'development' section. Next, we'll setup a section for the given controller ('user'), and a key for the form ('login'):

[development]
; general form metainformation
user.login.action = "/user/login"
user.login.method = "post"

; username element
user.login.elements.username.type = "text"
user.login.elements.username.options.validators.alnum.validator = "alnum"
user.login.elements.username.options.validators.regex.validator = "regex"
user.login.elements.username.options.validators.regex.options.pattern = "/^[a-z]/i"
user.login.elements.username.options.validators.strlen.validator = "StringLength"
user.login.elements.username.options.validators.strlen.options.min = "6"
user.login.elements.username.options.validators.strlen.options.max = "20"
user.login.elements.username.options.required = true
user.login.elements.username.options.filters.lower.filter = "StringToLower"

; password element
user.login.elements.password.type = "password"
user.login.elements.password.options.validators.strlen.validator = "StringLength"
user.login.elements.password.options.validators.strlen.options.min = "6"
user.login.elements.password.options.required = true

; submit element
user.login.elements.submit.type = "submit"

You would then pass this to the form constructor:

<?php
$config 
= new Zend_Config_Ini($configFile'development');
$form   = new Zend_Form($config->user->login);

and the entire form will be defined.
