Hello,

why not create a view of random nodes. create a block display for the view and place it in a region at the top of your page?

Hi All

I would like to show image files (in a random manner) at the top of webpage.

I want to have a folder that contains all the image files.

 

Then I want to have a separate php file (say rotate.php) having logic of selecting the random image file.

And want to include that rotate.php file from page.tpl.php.

 

To start with, I followed the marinelli view.

Used the images and rotate.php (\marinelli\img\banners\rotate.php).

 

Copied to image files and rotate.php to path where my page.tpl.php is present.

 

In page.tpl.php, I added the line  include ("rotate.php");

 

The rotate.php looks as below. On debugging looks preg_match line it breaks.
Please let me know why line "if ( preg_match( $regex, $file ) ) {" breaks.

 

Regards

Austin
