Zend Form Validate Range Date

Question

who gives me a hand to create a custom validator for the Zend Framework that checks that the date is in a range?

Example:

dateGT = 2011-09-05 dateLT = 2011-07-05 

if the form field is set to: dateFieldForm = 2011-08-15 I expect the validator to return true!

and if the form field is set to: dateFieldForm = 2011-10-15 I expect the validator to return false!

Sorry, big code ahead:

 <?php /** @see Zend_Validate_Abstract */ require_once 'Zend/Validate/Abstract.php'; /** * @category Zend * @package Zend_Validate * @copyright Copyright (c) 2005-2009 Zend Technologies USA Inc.

Using:

 $element->addValidator(new My_Validate_DateCompare('startdate')); //exact match $element->addValidator(new My_Validate_DateCompare('startdate', null)); //exact match $element->addValidator(new My_Validate_DateCompare('startdate', 'enddate')); //between dates $element->addValidator(new My_Validate_DateCompare('startdate', true)); //not later $element->addValidator(new My_Validate_DateCompare('startdate', false)); //not earlier 

Uses a globally set date format (stored in Zend_Registry ('Locale')).

It is also recommended that you configure error messages in each case.

Last update: fixed invalid optional parameter, which should be NULL instead of True. Changed messages to make them less confusing. Some formatting and spaces.

I am writing a test phpunit for a class by venimus. Hope this can help someone.

 class Validate_DateCompareTest extends PHPUnit_Framework_TestCase { public function dataForTest() { return array( array('2011-06-05', '2011-06-01', '2011-06-10', true), //between dates array('2011-06-10', '2011-06-01', '2011-06-10', true), //between dates array('2011-06-01', '2011-06-01', '2011-06-10', true), //between dates array('2011-06-15', '2011-06-01', '2011-06-10', false), //between dates array('2011-05-30', '2011-06-01', '2011-06-10', false), //between dates array('2011-06-01', '2011-06-01', null, true), //exact match array('2011-06-15', '2011-06-01', null, false), //exact match array('2011-05-30', '2011-06-01', null, false), //exact match array('2011-06-02', '2011-06-01', true, true), //not later array('2011-06-01', '2011-06-01', true, false), //not later array('2011-05-30', '2011-06-01', true, false), //not later array('2011-05-30', '2011-06-01', false, true), //not earlier array('2011-06-01', '2011-06-01', false, false), //not earlier array('2011-06-10', '2011-06-01', false, false), //not earlier ); } /** * @dataProvider dataForTest * @param $value * @param $token * @param $compare * @param $expected * @return void */ public function testDateCompare($value, $token, $compare, $expected) { /** @var $validate My_Validate_DateCompare */ $validate = new My_Validate_DateCompare($token, $compare); $this->assertEquals( $expected, $validate->isValid($value), "value: $value -- token: $token -- compare: $compare" ); } 

}

this class was really useful for me, thanks again!
