OOP extend problem.

[Bryce910]

I am new to OOP php programming and I am trying to figure out what I did wrong on this. I am trying to call my protection() function in my users class, so I extended my question class and call the protection function but it isn't working.

 

Here is my code for my class_lib:

 

<?php
require('dbc.php');
class users
{
public $email;
public $password;
public $first_name;
public $last_name;
public $id;

function __construct($e,$p)
{
	$this->email = $e;
	$this->password = $p;
}
function protection()
{
	if(!$_COOKIE['user'])
	{
		header("location:../login.php");
	}
}
}
//new class
class questions extends users
{
public $title;
public $question;
public $response;
public $sub_category;
public $date;
public $pid;

function __construct(){}

function newest()
{
	$sql = "SELECT * FROM math ORDER by pid DESC LIMIT 0,5";
	$execute = mysql_query($sql) or die(mysql_error());
	while($data = mysql_fetch_array($execute) )
	{
		$this->title = $data['title'];
		$this->question = $data['question'];
		$this->pid = $data['pid'];
		echo  '<p class="title">' . $this->title . '<br /></p>';
		echo ' <br /><br /><br /><br /><a href="questions.php?id=' . $this->pid . '" class="button">Awnser it</a><br /><br /><br />';
	}
}
}
?>

 

Here is the page to call the function:

 

<?php
require('../class_lib.php');
$question = new questions();
$question -> protection();
?>

Are you getting an error, or is it just doing nothing? If you are getting an error, post it here.

 

If you aren't getting an error, it could be that $_COOKIE_['user'] is set, thus running the code that isn't there.  You may want to try adding an else{} to that if statement to see if it's going there, just to test it.  Something like:

 

if(!$_COOKIE['user'])
	{
		header("location:../login.php");
	}else{
                        echo "Cookie is set";
                }

Before you go any further. Your *users* class should be named *user* is it obviously represents a single user. Extending that with *questions* make s little sense though I'm afraid. The two are in no way related.

 

A *user* may own some *questions* but that doesn't meen you extend a user to contain questions.

There was no error on it at all. It also didn't run the else statement so I am not sure! Also so you don't think I should extend it but instead write another protection function in the questions class?
