<?php require_once 'classes/view.php'; echo db_hostname; //output: hostname $view = new view(); if ($htmlstring = $view->tablethreads()) { echo $htmlstring; } else { echo $view->;htmlerror(); } echo $view->buttonpostthread(); ?> view.php

'; $html .= 'you can go <a href="index.php">the main page</a>.</p>'; }else{ // index.php $html = '<p class="error">there aren\'t threads. sorry! </p>'; } return $html; } function buttonpostthread() { return '<div class="newthread">' .'<a href="post_message.php">create new thread</a>' .'</div>'; }
you need correct line:
echo $view->;htmlerror(); to:
echo $view->htmlerror(); for rest, please check code.
