[FX.php List] foundCount and more

[DC]

i haven't used FMSkipRecords() in FX.php but that should help you.

In FMP6 with FX.php when you do a search and pass a limiting value to

$result=SetDBData($db,$layout,'25');

... for example, you'll get 25 records back (if there are more than 25) 
and the $result array will have the foundCount at:

$total_number_of_records_found=$result['foundCount']; // case sensitive

This alone gives you a 'data' array with the first 25 records in it 
(depending on sort order) and a 'foundCount' that has the total of all 
records matching your find request.

Add FMSkipRecords('25') before your find and you'll get the next 25 
records, and so on in multiples of 25 (or however many you want to see 
on the page at a time).

If you need something in native PHP, have a look at the array_slice() 
function in PHP. using that function you can get all records at once 
into FX.php and then just pull out a subsection of an array.

in both approaches, as Denny said, you'll have to track the details and 
counts in a session/cookie(recommended) or pass it in your URL (not 
recommended).

to get you going with keeping variables in session/cookies look at 
session_start() and the $_SESSION superglobal variable. e.g.,
$_SESSION['yourpagenumbervariablehere'] variable.

buena suerte,
dan
