phpBB is an popular open-source bulletin board software written in PHP. It logs IP’s automatically and stores them in the database. It’s very important for security purposes, but if you have concerns about data privacy you can disable IP logging permanently. Please note that your apache is logging IPs also…

1. Open includes/session.php

2. Search

   $this->ip = (!empty($_SERVER['REMOTE_ADDR'])) ? htmlspecialchars($_SERVER['REMOTE_ADDR']) : '';

3. Replace with:

   $this->ip = '127.0.0.1';

Now IP logging is disabled from now on… You probably have to apply this hack everytime after you updated the phpBB software.

If you want to clear all logged IP’s establish a connection to your MySQL database e.g. with phpMyAdmin and execute the following commands:

UPDATE phpbb_users SET user_ip='127.0.0.1';
UPDATE phpbb_log SET log_ip='127.0.0.1';
UPDATE phpbb_poll_votes SET vote_user_ip='127.0.0.1';
UPDATE phpbb_posts SET poster_ip='127.0.0.1';
UPDATE phpbb_privmsgs SET author_ip='127.0.0.1';
UPDATE phpbb_sessions SET session_ip='127.0.0.1';

If you have phpBB installed with Installatron it could be that your tables start with “bb_” and not with “phpbb_”…

Pinterest is gaining much popularity in the past few month and is growing faster than any other standalone site ever.
The connection between Pinterest and facebook is working pretty well so far, but despite the immense growth they haven’t released an official opportunity to embed your Pinterest profile as a tab on facebook yet. There are already some hacks out there which show how to embed your profile as a tab, but they are pretty ugly and look non-professional because the facebook canvas is narrower than the Pinterest profile. Anyhow a more professional and more appealing solution is to use the mobile version of your Pinterest profile instead of the normal version…

Below is a detailed step by step instruction how to add your Pinterest profile as a tab on facebook.  No coding skills required

Instructions

1. Go to the iframe tab facebook app and click on the pin iconbelow to install a page tab.
2. Choose your pagewhere you want to add the pinterest tab:
3. Now go to your newly created tab and edit the settings. Therefore you have to give the app access first. Choose “URL” at “Page Source” and paste below the URL of your mobile Pinterest profile (e.g. http://m.pinterest.com/YOURNAME/). Don’t know your profile URL? Log into Pinterest.com click on your profile image and you will go directly to your profile on Pinterest. Then copy the URL and add a “m.” (for “mobile”). Adjust the height and click “Hide Scrollbars”Don’t forget to click “Save Changes!”…
4. Done.

The result

That’s it. A pretty and clean Pinterest profile as a tab on facebook.

I wrote earlier an article about creating a pinterest profile tab by creating an own facebook application. The advantage is, that you can use the original Pinterest icon and you are not related to third-party apps. Unfortunately I failed because I got “CSRF verification failed” as a response. Did anyone managed to solve this issue?

I’ll show you how to get the monthly active users of your Facebook application via FQL with the help of PHP…

Ehh wait, what’s FQL?

“Facebook Query Language, or FQL, enables you to use a SQL-style interface to query the data exposed by the Graph API. It provides for some advanced features not available in the Graph API, including batching multiple queries into a single call.”

More information: Facebook FQL reference

At first you need to download the latest Facebook PHP SDK and include the facebook.php into your script.

require "facebook.php";

We are using the application table to get the information via FQL. The query is very similar to SQL and looks like this:

SELECT monthly_active_users FROM application WHERE app_id=000000000

It also possible to grab other values like daily_active_users, weekly_active_users, daily_active_users, name, description etc. Simply edit the FQL query…

Before we are allowed to get values of an application we need to authenticate with facebook. Go to facebook.com/developers/ and grad your unique application ID and application secret.

Here is the final php script:

<?php
// Facebook PHP-SDK
require "facebook.php";
 
define("APP_ID",      "00000000000");
define("APP_SECRET" , "abc123425abc123425abc123425");
 
$facebook = new Facebook(array(
  "appId"  => APP_ID, // app id
  "secret" => APP_SECRET, // secret hash
  "cookie" => true, // cookie support (optional)
));
try {
  // FQL Query
  $fql = $facebook->api(array(
                        "method"  => "fql.query",
                         "query"   => "SELECT monthly_active_users
						FROM application 
						WHERE app_id='".APP_ID."'"
					));
 
  echo $fql[0]['monthly_active_users'];
 
} catch (FacebookApiException $e) {
  // return errors
  print $e;
}
?>

Have you ever tried to download a great track (mp3) from soundcloud.com? There are several ways to download a track from SoundCloud… I’ll show you how it works.

Please check out first if there is small tiny “download” button at the top of the soundcloud player:

If yes, simply click download and wait. That’s it. The track is now on your hard drive.

If there is no such “download” button, you have to use a simple tool called JDownloader. It’s a great download manager written in Java. You can download it here for Windows, Linux, Mac or at jdownloader.org (~ 15MB) . Choose your Operating System (OS) and click on one of the links. You probably have to wait around ten seconds before you can download the file because the files are hosted on file hosters which offer premium accounts for users who don’t want to wait.

NOTE: you don’t have to buy or sign up on any of these sites. Simply wait a few seconds and click on “Free Download” and download the installer without any registration process…
After that, click through the installation process. If everything is installed correctly, launch the JDownloader. Now go tou soundclod.com and copy the URL of the track you want to download. If the JDownloader does not open automatically after a few seconds, open it manually and click the tab “Linkgrabber” and then “Add URL(s)”. Paste the URL and click on “Parse URL(s)”. Finally you have to click on the play Button at the top to start the download.

The mp3 file is now downloaded to “C:/Program Files/JDownloader/downloads/” (if you are using Windows).

Make sure that you also have installed the latest version of Java if you have problems running the JDownloader. You get the latest version on java.com.

NOTE: The downloaded file is only the preview file (up to 128 kbps). It’s not the best quality available. For a better quality you have to buy the track and support the artist…

The Internet Explorer (IE) is acting strange when it comes to transparency, for instance transparent iframes like the retweet button from tweetmeme. I’m using the great Tweetmeme Plugin for WordPress, but the problem with the transparency appears no matter which way of implementation you are using.

In IE 6, 7 and 8 it looks like this (ugly white background):

But is should look like this (transparent > black background):

Here is the workaround: Go to “Appearance > Editor > Header (header.php)” and paste this snippet before the </head> tag and click on “Update File” to save the changes:

<!--[if IE]>
<script type="text/javascript">
onload = function()
{
	var theframes = document.getElementsByTagName('iframe');
	for(var i = 0; i < theframes.length; i++)
	{
		theframes[i].setAttribute("allowTransparency","true");
	}
}
</script>
<![endif]-->

Thanks to the _Aerospace_Eng_ who posted this snippet here.

This will add transparency to all iframes in the Internet Explorer (IE) and removes the white section between both parts. That’s it… Did you succeeded? Let me know!

This error appeared every time I wanted to install a theme automatically, even in the current version (2.9.1) of WordPress:

Downloading install package from http://wordpress.org/extend/themes/download/sample-theme.zip.
Unpacking the package.
Installing the theme.
Could not create directory. /var/www/html/web999/blog/wp-content/themes/sample-theme/
Theme Install Failed.

This is caused by an error when running the php function mkdir() under safe_mode on certain versions of PHP (I’m using PHP Version 5.2.5). The bug is already tracked and probably will be fixed in the next version of WordPress…

There are two solutions to fix this by your own

1. Solution – Edit class-wp-filesystem-direct.php
   Add the marked lines in your wp-admin/includes/class-wp-filesystem-direct.php (Line 281):
   

   function mkdir($path, $chmod = false, $chown = false, $chgrp = false) {
      // safe mode fails with a trailing slash under certain PHP versions.
      $path = untrailingslashit($path);
      if ( empty($path) )
         $path = '/';
   
      if ( ! $chmod )
         $chmod = FS_CHMOD_DIR;

OR

2. Solution – Turn safe_mode off
   I do not recommend this solution! But you can use it e.g. temporarily if you want to install a few themes in a row and turn safe_mode on again afterwards. If you are using Confixx you can edit these settings easily. Otherwise you have to edit your php.ini manually. How to do this? Check that: Customizing PHP Safe Mode

Now your Theme installation process should give you a response like this:

Downloading install package from http://wordpress.org/extend/themes/download/theme.zip.
Unpacking the package.
Installing the theme.
Successfully installed the theme Sample Theme.
