[PLUGIN] Wordpress specific template for first visit (and writes a cookie)

/ Published in: PHP

Highlighted TextExpand

<?php
/*
Plugin Name: first-visit-template
Description: Loads a welcome.php template in theme directory if it is the first visit (the function is not lauched if you're logged as admin), and writes a cookie so it's shown only once.
Author: G.Lachance
Author URI: http://tinyurl.com/9wb48o
Credits: Based upon the "Welcome Visitor! Reloaded" plugin from  Alaeddin, which is largely based upon the original Welcome Visitor! plugin by Kaf (http://guff.szub.net/2006/04/12/welcome-visitor/)
which was released under the GNU General Public License.
Version: 1

//for testing your template, uncomment line 30.

function welcome_visitor_reloaded() {

if(is_new_visitor()) {
		$tpl_file = TEMPLATEPATH . '/welcome.php';
		if ( file_exists($tpl_file) ) {
			include($tpl_file);
			exit;
		}
	}				
}

function is_new_visitor()
{

//return true; //uncomment this for testing.
 	
	global $visits;
	
	if (!is_admin())
	{
		if (isset($_COOKIE['visits']))
			$visits = $_COOKIE['visits'] + 1;
		else
			$visits = 1;
			
		$url = parse_url(get_option('home'));
		setcookie('visits', $visits, time()+60*60*24*365, $url['path'] . '/');
	}
	else return false;

return $visits == 1;
}

///
add_action('template_redirect', 'welcome_visitor_reloaded');
