Database Design for Facebook Timeline Wall Script

Security wise I have added more features like

• Fix urls with protocol (http://, https://)
• Remove PHP, Javascript Tags, Clean Texts
• Clickable Text Links –  convert text to url hyperlink

Facebook Timeline Wall Script – Version 1.0 contains 4 folders

• assets
  • Stylesheets
  • Javascripts
  • Images
• Includes
  • config.php
  • security.php
  • SimpleImage.php – used to upload images
• Uploads – all pictures are uploaded to this folder

All you have to do is simply download and upload the sql file. finally some minor changes to be done in config.php

Config.php

define('DB_SERVER', 'localhost');

define('DB_USERNAME', 'root');

define('DB_PASSWORD', '');

define('DB_DATABASE', 'fb_wall'); //your database name

define('ImageUploadPath', 'uploads/'); // image upload path

$post_limit = 10;

$connection = mysql_connect(DB_SERVER, DB_USERNAME, DB_PASSWORD) or die(mysql_error());

$database = mysql_select_db(DB_DATABASE) or die(mysql_error());

mysql_query ("set character_set_results='utf8'");

$base_url='http://localhost/facebook-timeline-demo-1/'; //base url

$base_folder = "facebook-timeline-demo-1/"; //leave empty if you using root folder

Security.php

//remove php tags from input

function clean($text)

{

$return_text = strip_tags($text);

return $return_text;

}

//remove special character from text

function special_chars($str)

{

$str = htmlentities($str, ENT_COMPAT, 'iso-8859-1');

$str = preg_replace('/&(.)(acute|cedil|circ|lig|grave|ring|tilde|uml);/', "$1", $str);

return $str;

}
//fixing the urls

function fix_url($url)

{

if (substr($url, 0, 7) == 'http://') { return $url; }

if (substr($url, 0, 8) == 'https://') { return $url; }

return 'http://'. $url;

}
function _make_url_clickable_cb($matches) {

$ret = '';

$url = $matches[2];
if ( empty($url) )

return $matches[0];

// removed trailing [.,;:] from URL

if ( in_array(substr($url, -1), array('.', ',', ';', ':')) === true ) {

$ret = substr($url, -1);

$url = substr($url, 0, strlen($url)-1);

}

return $matches[1] . "<a href=\"$url\" rel=\"nofollow\" target=\"_blank\">$url</a>" . $ret;

}
function _make_web_ftp_clickable_cb($matches) {

$ret = '';

$dest = $matches[2];

$dest = 'http://' . $dest;
if ( empty($dest) )

return $matches[0];

// removed trailing [,;:] from URL

if ( in_array(substr($dest, -1), array('.', ',', ';', ':')) === true ) {

$ret = substr($dest, -1);

$dest = substr($dest, 0, strlen($dest)-1);

}

return $matches[1] . "<a href=\"$dest\" rel=\"nofollow\" target=\"_blank\">$dest</a>" . $ret;

}
function _make_email_clickable_cb($matches) {

$email = $matches[2] . '@' . $matches[3];

return $matches[1] . "<a href=\"mailto:$email\">$email</a>";

}
function make_clickable($ret) {

$ret = ' ' . $ret;

// in testing, using arrays here was found to be faster

$ret = preg_replace_callback('#([\s>])([\w]+?://[\w\\x80-\\xff\#$%&~/.\-;:=,?@\[\]+]*)#is', '_make_url_clickable_cb', $ret);

$ret = preg_replace_callback('#([\s>])((www|ftp)\.[\w\\x80-\\xff\#$%&~/.\-;:=,?@\[\]+]*)#is', '_make_web_ftp_clickable_cb', $ret);

$ret = preg_replace_callback('#([\s>])([.0-9a-z_+-]+)@(([0-9a-z-]+\.)+[0-9a-z]{2,})#i', '_make_email_clickable_cb', $ret);
// this one is not in an array because we need it to run last, for cleanup of accidental links within links

$ret = preg_replace("#(<a( [^>]+?>|>))<a [^>]+?>([^>]+?)</a></a>#i", "$1$3</a>", $ret);

$ret = trim($ret);

return $ret;

}
//function used to fetch youtube video id

function get_youtubeid($url)

{

$parse = parse_url($url);

if(!empty($parse['query'])) {

preg_match("/v=([^&]+)/i", $url, $matches);

return $matches[1];

} else {

//to get basename

$info = pathinfo($url);

return $info['basename'];

}

}

thats it. You are done.
