To implement, simply include this script at the top of your theme’s 404.php file. If your theme don’t have a 404.php file, then create it.
<?php // WP 404 ALERTS @ http://wp-mix.com/wordpress-404-email-alerts/ // set status header("HTTP/1.1 404 Not Found"); header("Status: 404 Not Found"); // site info $ blog = get_bloginfo('name'); $ site = get_bloginfo('url') . '/'; $ email = get_bloginfo('admin_email'); // theme info if (!empty($ _COOKIE["nkthemeswitch" . COOKIEHASH])) { $ theme = clean($ _COOKIE["nkthemeswitch" . COOKIEHASH]); } else { $ theme_data = wp_get_theme(); $ theme = clean($ theme_data->Name); } // referrer if (isset($ _SERVER['HTTP_REFERER'])) { $ referer = clean($ _SERVER['HTTP_REFERER']); } else { $ referer = "undefined"; } // request URI if (isset($ _SERVER['REQUEST_URI']) && isset($ _SERVER["HTTP_HOST"])) { $ request = clean('http://' . $ _SERVER["HTTP_HOST"] . $ _SERVER["REQUEST_URI"]); } else { $ request = "undefined"; } // query string if (isset($ _SERVER['QUERY_STRING'])) { $ string = clean($ _SERVER['QUERY_STRING']); } else { $ string = "undefined"; } // IP address if (isset($ _SERVER['REMOTE_ADDR'])) { $ address = clean($ _SERVER['REMOTE_ADDR']); } else { $ address = "undefined"; } // user agent if (isset($ _SERVER['HTTP_USER_AGENT'])) { $ agent = clean($ _SERVER['HTTP_USER_AGENT']); } else { $ agent = "undefined"; } // identity if (isset($ _SERVER['REMOTE_IDENT'])) { $ remote = clean($ _SERVER['REMOTE_IDENT']); } else { $ remote = "undefined"; } // log time $ time = clean(date("F jS Y, h:ia", time())); // sanitize function clean($ string) { $ string = rtrim($ string); $ string = ltrim($ string); $ string = htmlentities($ string, ENT_QUOTES); $ string = str_replace("\n", "<br>", $ string); if (get_magic_quotes_gpc()) { $ string = stripslashes($ string); } return $ string; } $ message = "TIME: " . $ time . "\n" . "*404: " . $ request . "\n" . "SITE: " . $ site . "\n" . "THEME: " . $ theme . "\n" . "REFERRER: " . $ referer . "\n" . "QUERY STRING: " . $ string . "\n" . "REMOTE ADDRESS: " . $ address .
