Hi everyone, have the coding below to get the next and previous records. However, still unable to get the next record as it shows the next record picid=14, where actually the next record supposed to be picid=40.The current record is picid=4. Please advise. Thanks.
error_reporting(E_ALL ^ E_NOTICE);
//check if the starting row variable was passed in the URL or not
if (!isset($_GET['picid']) or !is_numeric($_GET['picid'])) {
//we give the value of the starting row to 0 because nothing was found in URL
$picid = 0;
//otherwise we take the value from the URL
} else {
$picid = (int)$_GET['picid'];
//this part goes after the checking of the $_GET var
$fetch = mysql_query("SELECT * FROM general,progress LIMIT $picid, 10")or
//now this is the link..
echo 'Next';
$prev = $picid - 10;
//only print a "Previous" link if a "Next" was clicked
if ($prev >= 0)
echo 'Previous';

You need to show what you do with $fetch .

Also, without an order by in your query you cannot be sure what record comes next.

i can send you a better detailed pagination class if you want

Hi, thanks for your reply. The $fetch suppose to display the next record. Appreciate if you could send a better detail pagination. Thanks a lot.

NOTE all these is a single file the one at the tops is the getting the info from dp and middle the info you want to paginate might ba a div
and the last block are the pagination links.
