    Default mysql_num_rows query

    $ID = $_GET['ID'];

    $limit=2; // rows to return
    $numres=mysql_query("SELECT * from fragrances WHERE ID=$ID ORDER BY title");
    $numrows=mysql_num_rows($numres);

    // next determine if offset has been passed to script, if not use 0
    if (empty($offset)) {
    $offset=0;
    }

    // get results
    $result=mysql_query("ima_link, title, size, rrp, £, SHO, cli_link, buy_link ".
    "from fragrances WHERE ID=$ID ".
    "ORDER BY title LIMIT $offset,$limit");

    // now you can display the results returned
    echo "<table border='0' cellpadding='5' cellspacing='0' width='500'>";
    while($row = mysql_fetch_array( $numres )) {
    // Print out the contents of each row into a table
    echo "<tr><td align='center' bgcolor='#ffffff' rowspan='2' valign='top' width='125'>";
    echo $row['ima_link'];
    echo "</td><td align='center' bgcolor='#ffffff' valign='top' width='250'><p class='main_title'>";
    echo $row['title'];
    echo "</p></td><td align='center' bgcolor='#ffffff' rowspan='2' valign='top' width='125'><p class='main_type'>";
    echo $row ['size']. " ". $row['type'];
    echo "</p><p class='main_rrp'>RRP &#163;";
    echo $row['rrp'];
    echo "</p><p class='main_&#163;'>DFUK &#163;";
    echo $row['&#163;'];
    echo "</p><p class='main_shop'>";
    echo $row['SHO'];
    echo "</p><p class='main_buttons'>";
    echo $row ['cli_link']. $row['buy_link'];
    echo "</p></td></tr><tr><td align='center' bgcolor='#ffffff' valign='top' width='250'><p class='main_manufacturer'>";
    echo $row['manufacturer'];
    echo "</p></td></tr><tr><td align='center' bgcolor='#ffffff' colspan='3' valign='top' width='500'><hr color='#999999' width='95&#37;'></hr>";
    echo "</td></tr>";
    }

    echo "</table>";
    // include code to display results as you see fit

    // next we need to do the links to other results

    if ($offset==1) { // bypass PREV link if offset is 0
    $prevoffset=$offset-20;
    print "<a href=\"$PHP_SELF?offset=$prevoffset\">PREV</a> &nbsp; \n";
    }

    // calculate number of pages needing links
    $pages=intval($numrows/$limit);

    // $pages now contains int of pages needed unless there is a remainder from division
    if ($numrows%$limit) {
    // has remainder so add one page
    $pages++;
    }

    for ($i=1;$i<=$pages;$i++) { // loop thru
    $newoffset=$limit*($i-1);
    print "<a href=\"$PHP_SELF?offset=$newoffset\">$i</a> &nbsp; \n";
    }

    // check to see if last page
    if (!(($offset/$limit)==$pages) && $pages!=1) {
    // not last page so give NEXT link
    $newoffset=$offset+$limit;
    print "<a href=\"$PHP_SELF?offset=$newoffset\">NEXT</a><p>\n";
    }

    ?>

    there seems to be some sort of trouble when it comes to the 2nd/next page scenario and it's not limiting results to just 2 like it's supposed to

    bear in mind, i know the table syntax is abysmal and i will be fixing it once i have got the functionality working. lol. snap with the $ID = $_GET['ID'];

    Default

    OK, have discovered one thing at least, forgot to add the "ID=$ID&" following $PHP_SELF for all the subsequent page links. but i'm still stuck as to why the limit attribute isn't working properly. it should be limiting to just 2 products being displayed; instead it's displaying all
