Help me to get Table formatted foreach loop to display images.

[harika_99]

Hi,

Please help me to get images in table format. I'm new to PHP.

I have written code to display images in a table format and I set to displays only 9 images in a single page. when i click Next Url to go to next page, by default it returns to home page. I stored images in local directory and written for each loop to display images in table format, Without using mysql as backend.

So, My question is how to display bunch of images in table formated (3x3) column and rows format with next link to navigate to the next page?

Please help! Thanks in advance!

search the forum for pagination although a database is generally used the principle is the same and has been covered many times before.

This is my PageNavigator code :

  private $lastinactivespan;  

  //must match $_GET['offset'] in calling page

For your pagination, use either glob or scandir to get an array of files. count() on this array to get number of files. This matches the SELECT COUNT(*) or SQL_CALC_FOUND_ROWS used to get total number of items in the database approach.

Note that glob() is probably preferable to scandir() since glob lets you specify a filter, such as '/path/to/*.jpg' while scandir even returns the directories . and ..
