So in this code all I am trying to do is create a view chores page.
I have created a chore class and a choreDAO class, which my view_chores page is calling from.
I have used the exact same code with other pages such as view_members and they also have the other two classe and they work fine!
The error occurs in the view_chores.php file below; this line of code:
echo "<b>Title:</b> " . $chore->getChoreName() . "<br />";
any help would be great. thank you!
Here is my view_chores.php page.
<?php
ob_start();
require_once 'includes/Member.php';
require_once 'includes/MemberDAO.php';
require_once 'includes/Chore.php';
require_once 'includes/ChoreDAO.php';
require_once 'includes/session.php';
confirm_logged_in(); // needs to come before any html because it does a redirect
?>

$choreDAO = new ChoreDAO();
$chores = $choreDAO->getChores();

echo "<p>These are the current chores: </p>";
foreach ($chores as $chore) {
echo "<b>Title:</b> " . $chore->getChoreName() . "<br />";
echo "</p>";
}
echo $display; ?>
<a href="add_chore_form.php">Add Chore?</a>

<?php ob_flush(); ?>
Here is my Chore.php
<?php
class Chore {
private $id;
private $chore_name;
public function __construct($i, $chore_name) {
$this->id = $i;
$this->chore_name = $chore_name;

public function setChoreName($cn) { $this->ChoreName = $cn; }
}

In your ChoreDAO class getChores() method, you are using this:
Where it should be:
