I am trying to display an array of messages at the end of my PHP class. My message handler is working, but only if I "add_message" from within the main parent class and not if I call this function from within a child class. Sorry if this is vague but was not sure how to word the question.
TLDR; How can I add a message from within class Example?
MAIN PARENT CLASS
class Init {
public function __construct() {
$this->load_dependencies();
$this->add_messages();
$this->add_msg_from_instance();
}
private function load_dependencies() {
require_once ROOT . 'classes/class-messages.php';
require_once ROOT . 'classes/class-example.php';
}
public function add_messages() {
$this->messages = new Message_Handler();
$this->messages->add_message( 'hello world' );
}
// I Would like to add a message from within this instance....
public function add_msg_from_instance() {
$example = new Example();
$example->fire_instance();
}
public function run() {
$this->messages->display_messages();
}
}
MESSAGE HANDLER
class Message_Handler {
public function __construct() {
$this->messages = array();
}
public function add_message( $msg ) {
$this->messages = $this->add( $this->messages, $msg );
}
private function add( $messages, $msg ) {
$messages[] = $msg;
return $messages;
}
// Final Function - Should display array of all messages
public function display_messages() {
var_dump( $this->messages );
}
}
EXAMPLE CLASS
class Example {
public function fire_instance() {
$this->messages = new Message_Handler();
$this->messages->add_message( 'Hello Universe!' ); // This message is NOT being displayed...
}
}
