My question is that how can i repeat the query on next pages using sessions. i.e i want to store the query if the pages exceeds results from 1 page. basically listing. I cant figure out the logic for storing the query and check for condition that the page is loaded first time or it is continuing search result.
sorry for improper formatting.
Well, ASP defines property IsPostBack for every page which answers your question whether page has been loaded before. You can use same technique by creating custom bussiness class instance of which you store in $_SESSION[‘bl’] and check if $_SESSION[‘bl’] is null. In that class you could define properties that store your query and other desired parameters. Then you’ll have all information you need and can go from there
