Checkbox pagination

[rahulj5]

I have pagination in the page. The problem I have is, I will loose the status of the checkbox when I go to second page. If I select some of the checkboxes in page 1 and go to page 2 to select some more and if I come back, I loose all the selected checkboxes in page 1.
Is there a way where I could save my check boxes in session and its checked while I browse across pages and gets submitted all at once? Could you please help me?

Please include your code so that we can take a look at it, we can't do much without it. When you do post your code remember to use [code] tags. That includes [ html ], [ code ], and [ php ].

Please post a link to the site you found this script at.

Please post a link to the page on your site that contains the problematic script so we can check it out.

Please do the above before further help.

Also - are you using ajax to load the pages or is it within a div?

My actual proble is as follows:
Above code is working, but i want some modifications in it. And i am not getting it.

when i click on some checkbox of table"Table Containts" and submit ">>" button, then in "Total Selected Domains" table , it is displaying checked checkboxes. But at same time , whatever the displaying in "Total selected Domains", only that checkboxes should be checked in "Table Containts" simultaneously., So basically i want to avoid duplicate selection of same checkboxes.
waiting for your reply.
Thank you for yor help in advance
