Replace array's content in new page Class

[gfd]

Hello,

I have created a very simple class to create new pages but I'm having problems changing the contents of an array in the new page.

This is the code for the class:

class Page
{
	var $content;
	var $messages = array ( 'this is value 1' , 'this is value 2' );

function SetContent($newcontent) {
	$this->content = $newcontent;
  }
	function SetMessages($newmessages) {
 		$this->messages = $newmessages;
  }
	function DisplayMessages($messages) {
			foreach ($messages as $current)
							echo $current.'<br> ';
	}
	function Display() {
		echo $this->content;
		$this -> DisplayMessages($this->messages);
  }
}

and this is the code for the new page:

	require ('newpage.php');
	$examplepage = new Page();

$examplepage -> SetContent('<p>This is the main content</p>');

$examplepage -> Display();

I would like to be able to change the contents of the $messages array on the new page so that I can enter error messages for a form.

I think I can create the error messages and store them in an array like this:

if (empty($name) ) {	
$msg[0] = 'You did not provide your name.<br />'; 
}	
if (empty($surname) ) {	
$msg[1] =  'You did not provide your surname.<br />'; 
}
if (empty($email) ) {	
$msg[2] = 'You did not provide your email address.<br />'; 
}

These error messages will need to replace the contents of the $messages array and show on the new page.

I have tried everything I could think of.
Can anybody help?

Thanks in advance.

Hi gfd,

Not 100% sure what exactly your problem is, but here's a template that might help you.

<?php 
// This will remain the same for all pages/sites
class GeneralPage { 
	var $content; 

// Not sure why you want to have default messages
var $messages = array(
	'this is value 1'
, 	'this is value 2'
);

// Maybe don't add the 'HTML' at the 'general' level
// Do that at the 'particular' level ... see below
function SetContent($newcontent){ 
	$this->content = $newcontent; 
}
function GetContent(){ 
	return $this->content; 
}

function AddMessage($newmessage){ 
	$this->messages[] = $newmessage; 
}
// Clear messages if you need to
function ClearMessages(){ 
	$this->messages = array(); 
}
function GetMessages(){ 
	return $this->messages;	
}

}

// Can use this on a per-page(site) basis
// Apply the 'particular' HTML, styles, etc. at this level
class ParticularPage extends GeneralPage {
	// Overdoing it a bit here, but you get the drift
	function DisplayContent(){
		echo '<p>'.$this->GetContent().'</p>';
	}
	function DisplayMessages(){
		echo join('<br />', $this->GetMessages());
	}
	function Display(){
		$this->DisplayContent();
		$this->DisplayMessages();
	}
}
// Remember to create a 'particular' instance
// Use the ampersand after the equals sign (see about references)
$examplepage =& new ParticularPage();
$examplepage->SetContent('This is the main content'); 

$examplepage->ClearMessages();
if(empty($name)){ $examplepage->AddMessage('You did not provide your name.'); } 
if(empty($surname)){ $examplepage->AddMessage('You did not provide your surname.'); } 
if(empty($email)){ $examplepage->AddMessage('You did not provide your email address.'); } 

// Display the lot
$examplepage->Display();
?> 

Come back if you have any trouble 😉

Paul.
