The Window.postMessage helps to make scripts talk over different domain connections. When you call a function on an external iframe from the parent window, Javascript won’t allow it. That’s because of the Cross Domain Policy that makes this not possible. But it’s possible since Javascript introduced postMessage function. Suppose you want to call a function on an cross domain iframe with id monu. Let the function be subins(). Here’s how to do it using postMessage technic.... [READ MORE]

We are going to use **PDO ( PHP Data Object **). Download Demo UPDATE – logSys There is a new, free, better Advanced Login System which you can check out here.... [READ MORE]

As you know, Google Chrome‘s Browser History is not efficient. It’s history is not like any other browsers. I think they made the History page in a hurry. If we want to search for a page we visited before, we won’t get it by searching on History page. That’s the main problem. This problem was solved when a lot of users created an alternate History Page extension on Chrome Webstore. In this post I’m gonna tell the most used History Alternate Extension.... [READ MORE]

The maximum width we can add on a div is 100%. What if you want more than that ? The solution is not to add more percentage to div but to do something other. Adding white-space property. This will only work on the main parent elements such as elements with display property as follows: block table inline-block So now you know what are the main parent elements. Now back to the point, to add infinite width set the white-space property to the value nowrap.... [READ MORE]

In this post I’m going to show the function that will generate a random string of length mentioned. Here is the function: function rand_string($length) { $str=""; $chars = "subinsblogabcdefghijklmanopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $size = strlen($chars); for($i = 0;$i < $length;$i++) { $str .= $chars[rand(0,$size-1)]; } return $str; } Usage To generate a random string use rand_string() function with the parameter of length of the to be generated string....
