[justAnoob]

I try to pass the variable to another page.. but it does not work.. check out the commented line.

      <form id="form2" name="form2" method="post" action="updatetrade.php">
        <?php
session_start();
include "connection.php";
if (isset($_GET['pageno']))
{
  $pageno = $_GET['pageno'];
}
else
{
  $pageno = 1;
}
$findit = $_SESSION['id'];
$result = mysql_query("SELECT id FROM members WHERE username = '$findit' LIMIT 1");
$e_row = mysql_fetch_assoc($result);
$query = mysql_query("SELECT count(*) FROM abcxyz WHERE user_id = " . $e_row['id']) or die(mysql_error());


$query_data = mysql_fetch_row($query);
$numrows = $query_data[0];
$rows_per_page = 1;
$lastpage = ceil($numrows/$rows_per_page);
$pageno = (int)$pageno;
$prevpage = $pageno-1;
$nextpage = $pageno+1;


if ($pageno > $lastpage)
{
  $pageno = $lastpage;
}
if ($pageno < 1)
{
  $pageno = 1;
}
$limit = 'LIMIT ' .($pageno - 1) * $rows_per_page .',' .$rows_per_page;

$sql = mysql_query("SELECT id, category, imgpath, imgpath2, imgpath3, imgpath4, imgpath5, item_name, description, in_return FROM abcxyz WHERE user_id = " . $e_row['id'] . " $limit");

You need to start your session at the very top of the page, before you do anything else (ie create your form).

I have it at the top of the page,, I just put it there to show that I'm using session start.

justAnoob, please use better formatting. It's such a pain for others to help you when they have to painfully find all your matching closing braces because of poor indentation. It's hard for you too. Even if you like it like that, please consider indenting it and using better format if you want others to help you.

 

$row is *not* defined outside of the while loop. If you had formatted your code, you would have known that easily.
