Incrementing/decrementing a range of numbers

Hello everyone,

This has been bugging me for a bit now. I want to make a simple range of number that I can go next 10 or previous 10(without refreshing the page).

example:

A) prev 1 2 3 4 5 6 7 8 9 10 next

if prev is clicked i should be like this

B) prev -9 -8 -7 -6 -5 -4 -3 -2 -1 -0 next

if next is clicked it goes back to A)

if next is clicked again is should output

C) prev 11 12 13 14 15 16 17 18 19 20 next

and so on...

I basically want to be able to scroll infinially both ways wiouth refreshing the page. This may seem easy for you guys but I can't figure it out. Help me please!!!

 

Create a file called pagination.php

<?
    $numofpages = $totalrows / $limit;

    for($i = 1; $i <= $numofpages; $i++){
        if($i == $page){
            echo($i." ");
        }else{
            echo("<a href=\"$PHP_SELF?page=$i">$i</a> ");
        }
    }


    if(($totalrows % $limit) != 0){
        if($i == $page){
            echo($i." ");
        }else{
            echo("<a href=\"$PHP_SELF?page=$i">$i</a> ");
        }
    }

?>

Code (markup):

Now on your main page you would do something like:

<?        
        $limit = 10;
        if(empty($page)){
        $page = 1;
        }
        # Pagination Cofig

        $limitvalue = $page * $limit - ($limit);
        $sql = "select * from table";
        $result = mysql_query($sql);
        $totalrows = mysql_num_rows($result);

        while ($row = mysql_fetch_array($result)) {
        #show your results
         }

#Now show pages
include "pagination.php";
?>

Code (markup):

This example may be a little more complex then what you want because I am using mysql to do it.

But based off this logic I am sure you can use it in a "for each" statement all the same

where $i < 11 etc.


Hope this helps!

 

Thanks for the quick reply. I'm familiar with paging but this is kind of different. I will be in a range of -trillions to +trillions. I need the numbers to be created dynamically instead of gabbing sql db stored numbers. As a user clicks next/previous it will fetch the numbers in the sequence I specify. The main thing is that all this has to be done using AJAX so the user can "scroll" through the numbers without refreshing.
