[SOLVED] class extends

[corillo181]

how come my var array is returned Empty?

 

<?php
class displayA{
protected $db;
public $name = array();
public $info = array();
public $img = array();


function __construct(){
	$this->db = new DB();	

}

function addToArray(){
	$this->name[] = "juan";
}

function getNames(){
	var_dump($this->name);
}
}

class allArtist extends  displayA {

function __construct(){
	parent::__construct();
}

function getName(){
	parent::getNames();
}
}

$ini = new displayA();
$ini->addToArray();

$show = new allArtist();
$show->getName(); // RETURN EMPTYS
?>

well no need of overidding function getName(){

parent::getNames();

}

OVER RIDDING?

[rajivgonsalves]

Oh I see sorry mistake in seeing 

 

parent::getNames();

 

$this->getNames();

[corillo181]

are you sure you have any experience with classes?

 

anyways it worked this way

 

<?php
include_once($_SERVER['DOCUMENT_ROOT'].'/include/header.php');

class displayA{
protected $db;
public $name = array();
public $info = array();
public $img = array();


function __construct(){
	$this->db = new DB();	

}

function addToArray(){
	$this->name[] = "juan";
}

function getNames(){
	return var_dump($this->name);
}
}

class allArtist extends  displayA {

function __construct(){
	parent::__construct();
}

function getName(){
	parent::addToArray();
	parent::getNames();
}
}

$show = new allArtist();
$show->getName();
?>

You've created 2 DIFFERENT objects...

$ini = new displayA();

$ini->addToArray();

 

$show = new allArtist();

$show->getName(); // RETURN EMPTYS

 

$ini has inside it the array of names of which Juan is one.

however $show (which extends displayA NOT $ini) has an array of names inside it, which is empty, because you haven't added any...

[aschk]

What you SHOULD be doing is :

 

$show = new allArtist();
$show->addToArray();
$show->getNames();

 

You don't even need the getName() function in allArtist...

For any more object oriented help try the specific OOP help part of the forum.

I like hanging around there
