I'm using Wordpress to implement the website:
The pages in my templates should be sliding vertically, so there is a 'Next' button in the end of each page. Now my problem is in the admin section 'Pages', I want to add a new attribute called NextPage which allows the user to choose one of the existent pages to be the next one. I did the behavior of the parent attribute. it is displayed right after the order attribute. but i didn't succeed to keep up the value in each update. My question is that how can i succeed in updating the data base with my new attribute ( i already add a new attribute in the data base called post_next_page in the Posts table).
Thank you for the help
