Enable Use Lightbox in Joomla 2.5/3.0

If you decided that you want to have a lightbox on your Joomla site, you probably know what is it about. But, let’s just mention that the Lightbox is a JavaScript technique to display images and content using modal dialogs. Why do you need this? Because it’s clean, nice looking, effective and easy for implementation.
We will learn how to display

•     images in modal popup window
•     external content

First thing we have to do is to add a bit of JavaScript support to our page.
To do this, paste the following code in the top of your main template file (ex. index.php) :

 When you did this, just use the link in the following format in your article or page.

< a href=”my-url” class=”modal”> Image or Text for a popup < /a>

For displaying content in the modal popup window you need a bit more code:

< a 
href="/sample/lightbox.html?map=1&act=3"
 class="modal" rel="{handler: 'iframe', size: {x: 575, y: 300}}">link
 to a modal popup with a dimension of 600px by 300px< /a> 

 It’s pretty much same as displaying images, expect we have “rel” attribute where we are saying that iframe should be used, and we also define exact size of the window were our content will be displayed.

SQL_CALC_FOUND_ROWS / FOUND_ROWS() does not work in PHP

$s1 = $sql->query('select SQL_CALC_FOUND_ROWS * from db limit 0, 3');
$s2 = $sql->query('select FOUND_ROWS()');
if($row = $s2->fetch_row()) printf('%d/%d', $s1->num_rows, $row[0]);

Sometime, when we run something analogous to above example on the mysql command line, it would work; but running it from php, it failed. The second query has to "know about" the first one, so for some reason its persistence/memory linking the two queries was getting messed up by the php.

(It turns out that Wordpress uses this type of query to do its pagination - so our larger problem was that the pagination in a wordpress install suddenly stopped working when we moved to php 5.2.6 ... eventually tracked it down to the FOUND_ROWS()).

Just for the sake of posting for people who may run into this in the future... for me it was the php setting "mysql.trace_mode" - this defaulted "on" in 5.2.6 instead of "off" like previously, and for some reason prevents the FOUND_ROWS() from working.

As a "fix", we could either put this in every php page (actually, in a common "include"):

ini_set("mysql.trace_mode", "0");

or add this to the .htaccess:

php_value mysql.trace_mode "0"

Install SQLYog with Wine in Ubuntu 12.04

First, download the SQLYog from here. Before that, make sure that you have already installed the wine into your machine, if you don't know how to install wine, refer to this link.

Afterwards, run the following command in terminal (use CTRL+ALT+T to open terminal).

wine /home/rc/Downloads/SQLYog-10.4.0-2-trial.exe 

Then, it should execute the .exe file, and just follow the SQLYog installation as like normally.
However, if you stuck with some error like below;
  wine is not owned by you , err msg.....

In that case, just run the below command (where rc is the shell user). Then run the above command again once the below command is successfully executed.

sudo chown -R rc:rc ~/.wine 


Enjoy !!!

Install Wine in Ubuntu 12.04, or Linux or Linux Mint

Wine enables Linux, Mac, FreeBSD, and Solaris users to run Windows applications without a copy of Microsoft Windows. Wine is free software under constant development. Other platforms may benefit as well. 

Wine 1.5.4 has just been released and this brief tutorial is going to show you how to install it in Ubuntu 12.04. Wine is an open source application which lets you install and run programs designed for Microsoft Windows systems in Linux systems. Not all your Windows programs will run with Wine, but many popular software that you depend on which run in Windows will run perfectly in Ubuntu using Wine.

With this release, comes many enhancements and bug fixes from the previous released version. You can now run Microsoft Office 2003, 2007 properly, Adobe Premier Pro, support for .NET 4.0 and many other software. For a more detailed release note, click here.

To get started, Open the Terminal ( can use press Ctrl+Alt+T on your keyboard to open Terminal). When it opens, run the commands below to add Wine PPA.

sudo add-apt-repository ppa:ubuntu-wine/ppa

sudo apt-get install winetricks

Finally, run the commands below to update your system and install Wine 1.5

sudo apt-get update && sudo apt-get install wine1.5

Ubuntu: Upgrade error due to another package management application running 

Please, try some of these steps in order:

If you haven't already done so reboot your machine and try running the update again.

Try to run one of the below command or all on command line as;

sudo apt-get clean

sudo do-release-upgrade

sudo rm /var/lib/dpkg/lock 

Manually remove the lock file and try running the update again.

Difference between single and double quotes in PHP

Well first of all, single quotes are much more efficient than double quotes, which is shown in the results from a simple test, which you can find here:http://phpbar.isgreat.org/viewtopic.php?f=2&t=56

So, there obviously is a difference between them, but what is it?

Simply put, single quotes are completely static, where as double quotes are dynamic with changing values.
For example:

CODE: SELECT ALL

$someVar = 'more Text';
echo 'Some Text $someVar';

will output

CODE: SELECT ALL

Some Text $someVar

However, the same example but with double quotes:

CODE: SELECT ALL

$someVar = 'more Text';
echo "Some Text $someVar";

will output

CODE: SELECT ALL

Some Text more Text

Obviously single quotes will have a better efficiency than double quotes, because in single quotes, php does not process anything within it, where as with double quotes, php is constantly looking through the string for variable names to check and call.

So how do we use this new knowledge to our advantage?

Well, since single quotes do not process variables how do we add variables to the string?
Well if you haven't figured it out, we simply use the string addition character.
For example:

CODE: SELECT ALL

$str = 'more text';
echo 'some text and '.$str;

It is a bit of a hassle, but like in most things about programming, its usually efficiency vs programing time. A classic example of this is, C++ vs C#.

However, when using single quotes, depending on your php version, '\n' will output \n, so you will occasionally have to use, "\n" or PHP_EOL

well, if you still want to use double quotes, because your lazy 
there are still times when you may find it easier to use single quotes. for example, if you are outputting static text like HTML that has mass amounts of double quotes in it. Or if you want to output the name of a variable.

Of course, you could still do

CODE: SELECT ALL

echo "$"."varname";

instead of

CODE: SELECT ALL

echo '$varname';

but in that case you might as well just use single quotes.

---
So yes, there is a huge difference between the single and double quotes other than simple quote escaping.

Well, i hope this helps you a lot, and it is best to try to be as efficient as possible, ESPECIALLY when using loops. so its alright to use double quotes when your lazy, but be sure to avoid them when writing large loops, or commonly used functions.

Joomla 2.5 versions issues while upgrade. Joomla include/framework.php line 42 or line 35 error.

2.5.1 Installation Parse error: syntax error .. on line 35
Had the same error after using jUpgrade to move a 1.5.x site to 2.5.1. which is hosted by 1and1. Everything tested fine after the install and when I moved the jUpgrade folder to the correct folder to make the site live I got a similar error.

Fixed it by changing the htaccess.txt file to .htaccess and adding the following line

//Code:
# Line added to force register_globals OFF
AddType x-mapp-php5 .php
