<?php
// Start a Session
if( !session_id() ) @session_start();
// Include and Instantiate the Class
require_once('class.messages.php');
$msg = new Messages();
// Now you can add messages
$msg->add('s', 'This is a success message!');
$msg->add('e', 'This is a error message!');
$msg->add('w', 'This is a Warning message!');
$msg->add('i', 'This is a Information message!');
// If you need to check for errors (ie: when validating a form) you can:
if( $msg->hasErrors() ) {
// There ARE errors
} else {
// There are NOT any error
}
// Where ever you want to display the messages simply call:
echo $msg->display();
?>Now you can pass a URL as a third parameter, and the user will get redirected immediately after the message is added:
<?php $msg->add('e', 'An error has occurred.', 'http://website.com/page.php'); ?>
