You might have more luck if you [url="http://codeigniter.com/wiki/How_to_ask_a_good_question/"]ask a better question[/url].

Obvious things include separating and tagging (with [ code ]) your code partials, identifying intended & desired behaviour, and clearly describing how the actual results deviate from the expected results .. etc.

[eluser]rakish[/eluser]
ok sir..uhm is this how you browse in codeigniter, I mean browsing your file from folders?

$dirPath = dir('./media/img/images');

[eluser]jedd[/eluser]
There's no 'browse' capability per se - that is, if you're looking for a function that will generate a navigable front-end to your file system.

Rather than using the dir() function, you might use the [url="/user_guide/helpers/file_helper.html"]CI File Helper[/url] - say the get_filenames() function. Though you're not obliged to - you can still use vanilla PHP functionality wherever you want, of course.
