Drupal 7 – Almost here

Andreas Glaser — Tue, 04 Jan 2011 12:06:31 +0000

The waiting is almost over – Drupal 7 is finally going to be released tomorrow the 5th of January 2011.
D7 will bring loads of new and improved features, modules from D6 which proved to be useful that made it into the core and much better default administration layouts.

Especially the new layouts will help newbies to get their heads around Drupal in less time to fully enjoy the endless flexibility and efficiency.

Drupal certainly stood the test of time since it’s release in January 2001 and will definitely experience a boost from this major release.

Google Trends Comparison (Drupal vs Joomla vs Typo3 vs Concrete5)

If you haven’t yet worked with Drupal this is definitely the perfect time to get in touch.

Places all your questions will be answered

Personally I’ve been working with Drupal for many years now and developed quite some business websites on it and it gets my recommendation any time. (if you’re not a bloody rookie ;) )

Kohana 3 – ErrorException [ Warning ]: htmlspecialchars() expects at most 3 parameters, 4 given

Andreas Glaser — Fri, 11 Jun 2010 17:05:18 +0000

^?View Code CODE

1	ErrorException [ Warning ]: htmlspecialchars() expects at most 3 parameters, 4 given

If Kohana 3 throws this exception, that means that your currently installed PHP version is lower than 5.2.3 .
This can be easily be fixed by updating PHP to the latest stable version (recommended) or by changing one of Kohana (not recommended).

To fix it code wise open following file with your preferred editor

^?View Code CODE

1	/system/classes/kohana/html.php

Search for…

^?View Code PHP

1	return htmlspecialchars((string) $value, ENT_QUOTES, Kohana::$charset, $double_encode);

… and change it into

^?View Code PHP

1	return htmlspecialchars((string) $value, ENT_QUOTES, Kohana::$charset);

Done :)

PHP Beginners – How to get online time of a user

Andreas Glaser — Mon, 24 May 2010 16:49:04 +0000

A common task in web development is to track or show a users online time.

Theory

We record and save the time (in seconds) of the users first interaction with our website. On every following click we subtract this information with the current time.

Working example

^?View Code PHP

/* tell php to start a new or resume an existing session */
session_start();
 
/* store time of first user interaction */
if(!isset($_SESSION['session.started'])) {
 $_SESSION['session.started'] = time();
}
 
/* calculate time elapsed since first click */
$onlineTime = time() - $_SESSION['session.started'];
 
/* display online time in various formats */
print 'Seconds: '.$onlineTime;
print "
\n".'Minutes:'.floor(($onlineTime / 60));
print "
\n".'Hours:'.floor(($onlineTime / 60 / 60));
print "
\n".'Days:'.floor(($onlineTime / 60 / 60 / 24));

PHP – SRCDS/HTTP Synchronizer (Linux)

Andreas Glaser — Thu, 03 Dec 2009 17:03:04 +0000

I just came across a script I have totally forgotten about, which I wrote quite a while ago.
I haven’t managed to write a real documentation so far… anyway… feel free to try it.

All you need to do, is to install php in case you haven’t done it already!

Andreas Glaser — Tue, 04 Nov 2008 14:52:38 +0000

Navigation Guide written in JavaScript/Ajax/PHP

My order was to develop a navigation guide which should help the visitors to discover the most important content of a website. This “NaviGuide” had to be realized as JavaScript/Ajax/CSS pop up on the fact that much users are using pop up blocker.

[Show as slideshow]

This NaviGuide runs since 24.July 2008 at www.stz-baden-baden.de implemented in the well known Content Managment System “Joomla”.

Release – Imageloader

Andreas Glaser — Tue, 14 Oct 2008 11:34:58 +0000

A couple of weeks ago I developed a little “Online Image Uploader” based on my private “JaZzPHP Framework”. The website just consists of a simple upload form as well as rudimentary archive page.

Screenshot

The purpose is to simplify sharing screen shots, images etc..

This is basically a private tool, but if someone needs such a function – fell free to use it.
