Code snippet : WordPress qTranslate – Getting current language

So I was working with the qTranslate plugin of WordPress’s and needed to select an image depending on language. qTranslate provides a utility function which returns the current language.

The function is called qtrans_getLanguage() and it works as follows:

$currentLang = qtrans_getLanguage();
if($currentLang == 'fr')
{
//show french logo
$imageName = logoFR.png';
}
else if($currentLang == 'hi')
{
//show Hindi logo
$imageName = logoHI.png';
}
else
{
//show english logo to rest
$imageName = logoEN.png...

Code Snippet : javascript – Checking for blank spaces in sentence without regex

This is actually very interesting. I had a text field which expected a single word string and I had to check it on client side. Using jQuery and JavaScript’s split function we can easily check if an input string contains spaces or not.

split function accepts a delimiter as first parameter, a string as second paramter and splits the string into an array by that delimiter. Returns original string if delimiter is not found.

Here is the code I used :

// id of the textbox is timeTaken
var strText...

jQueryUI Sortable-tr width reduces when used with table

I am working on a project where I need to make a list of items sortable. Naturally, I used jQueryUI’s sortable component. Now it works great for elements like ul, or ol or any other html structure.

In my case the items were in a table and I had to make the tr’s sortable. Implementing the sortable gave me the desired behavior. Here is the code I used:

$('#tblSort tbody.content').sortable(
{
cursor: 'move'
});

But while dragging the rows, the width of cells inside currently dragged row was getti...

PHP: Get intersecting dates between 2 date ranges

Here is a small code snippet that will give you intersecting dates between 2 date ranges. Say, for example, you have 2 date ranges, 1-Jan-2011 to 31-Mar-2011 and 23-Feb-2011 to 4-May-2011. This function will give you 23-Feb-2011 to 31-Mar-2011 as result.

Here is the code:

$a1 = "2011-01-01";
$a2 = "2011-03-31";
$b1 = "2011-02-23";
$b2 = "2011-05-04";

$intersection = getIntersection($a1,$a2,$b1,$b2);
if($intersection === false)
{
echo 'No intersecting dates found';
}
else
{
echo 'From '.date('d-M-Y',...

Book Review: Mastering phpMyAdmin 3.3.x for Effective MySQL Management

Recently I was contacted by Richard from Packt Publication to review their new book “Mastering phpMyAdmin 3.3.x for Effective MySQL Management“. Being a PHP-MySQL developer and an avid reader of technical books myself, I instantly agreed.

It took me a bit longer to read it then I had expected. At first, I had decided to just skim through the important chapters but it was interesting enough to change my decision. I then read all chapters one by one and realized that despite using phpMyAdmin...
