Paging is done through a simple p Querystring parameter, e.g. www.myurl.com/grid?p=3 would be the third page; the repository is automatically fetching the right data, and also the total count of items. The size of each page is defined somewhere else and I don't need to worry about that in the query string. However, I support searching etc. as well. The

问题 Ok. i had created another question about this but i guess i had complicated it a bit.Ill try to simplify my problem here: Suppose you have this code: <?php if($_POST['page']){ $page = $_POST['page']; $cur_page = $page; $page -= 1; $per_page = 15; $previous_btn = true; $next_btn = true; $first_btn = true; $last_btn = true; $start = $page * $per_page; include"dbconnect.php"; $query_pag_data = "SELECT msg_id,message from test LIMIT $start, $per_page"; $result_pag_data = mysql_query($query_pag
