Using Virtual Fields in CakePhp

Virtual fields in cakephp are used as an alias in sql expressions. Alias is used to give a column a different name.

Example, to concatenate fields,

class Applicant extends AppModel {
    var $name = 'Applicant';
    var $virtualFields = array( 'name' => "CONCAT(Applicant.firstname, ' ', Applicant.lastname)" );
}

To access the virtual field

$this->Applicant->find( 'first', array( 'fields' => array( 'name' ) ) );

Scrolling to the Top and Bottom of the page using Mootools

Scrolling to the top and bottom is very easy in mootools. Check out the code below.

window.addEvent('domready', function(){

	var myFx = new Fx.Scroll(window);

	$('bottom').addEvent('click', function(e){
		e.stop();
		myFx.toBottom();
	});

	$('top').addEvent('click', function(e){
		e.stop();
		myFx.toTop();
	});

});

Lines 5-8 lets you scroll to the bottom of the page. While lines 10-13 lets you scroll to the top of the page. Easy huh?

Note: Fx.Scroll plugin must be included. Get it at Mootools More Builder.
