Question

this should be really simple but I can just not figure it out at the moment – I have searched and can’t find the right helping – maybe it’s my wording of my problem which is the issue – I know this is simple but as I have said I am brain dead at the moment!

this is what I want
Displaying 1 - 7 of 21 items

if there are 21 products in total with 7 per page it needs to say

1 – 7 of 21 on page one
8 – 14 of 21 on page two
15 – 21 of 21 on page three

pretty sure that is the right way to step up? anyway any help would be appreciated! and I can put a bounty on this – although small at least it’s something! thanks

Answer 1

If you know what page you’re on, and the number of entries per page, you can calculate it:

$limit = 7;
$page = 2;
$total = 21;

$upper = min( $total, $page * $limit);
$lower = ($page - 1) * $limit + 1;
printf( "Displaying %d - %d of %d on Page %d\n", $lower, $upper, $total, $page);

Now, just loop over pages 1 – 3 to see the output^Codepad:

Displaying 1 - 7 of 21 on Page 1
Displaying 8 - 14 of 21 on Page 2
Displaying 15 - 21 of 21 on Page 3

Edit: Using the OP’s variables:

$upper = min( $products_total, $pager_current * $limit);
$lower = ($pager_current - 1) * $limit + 1;
printf( "Displaying %d - %d of %d on Page %d\n", $lower, $upper, $products_total, $pager_current);
