Mysql query paginate multi variable results - php

Question

I would like to paginate my multi termed sql query in paginated results, page 1 works fine but page 2..previous or next do not pass the variable:
<?php
include "db.inc.php";
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * 15;
$term1 = $_REQUEST['term1'];
$term2 = $_REQUEST['term2'];
$term3 = $_REQUEST['term3'];
$term4 = $_REQUEST['term4'];
$sql ="SELECT * FROM cdrequests WHERE pname LIKE '%$term1%' AND date LIKE '%$term2%' AND date LIKE '%$term3%' AND dept LIKE '%$term4%' LIMIT $start_from, 15";
$rs_result = mysql_query ($sql);
$num_rows = mysql_num_rows($rs_result);
$query = mysql_query("SELECT * FROM cdrequests WHERE pname LIKE '%$term1%' AND date LIKE '%$term2%' AND date LIKE '%$term3%' AND dept LIKE '%$term4%'");
$number=mysql_num_rows($query);
print "<font size=\"5\" color=white><b>CD Requests</b></font> </P>";
print "<table class=\"table1\" STYLE=\"word-wrap:break-word;\" width=1100 border=\"1\" bordercolor=\"#000000\" bgcolor=\"E6E6E6\" style=\"border-collapse: collapse\" cellpadding=\"2\" cellspacing=\"1\"> .............
?>
<?php
$term1 = $_REQUEST['term1'];
$term2 = $_REQUEST['term2'];
$term3 = $_REQUEST['term3'];
$term4 = $_REQUEST['term4'];
$sql = "SELECT COUNT(id) FROM cdrequests WHERE pname LIKE '%$term1%' AND date LIKE '%$term2%' AND date LIKE '%$term3%' AND dept LIKE '%$term4%'";
$rs_result = mysql_query($sql);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / 15);
/****** build the pagination links ******/
// range of num links to show
$range = 3;
// if not on page 1, don't show back links
if ($page > 1) {
// show << link to go back to page 1
echo " <a href='search2.php?page=1'><b>First</b></a> ";
// get previous page num
$prev = $page - 1;
// show < link to go back to 1 page
echo " <a href='search2.php?page=$prev'><b>«</b></a> ";
} // end if
// loop to show links to range of pages around current page
for ($x = ($page - $range); $x < (($page + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $total_pages)) {
// if we're on current page...
if ($x == $page) {
// 'highlight' it but don't make a link
echo " <font size='5' color=yellow><b> $x </b></font> ";
// if not current page...
} else {
// make it a link
echo " <a href='search2.php?page=$x'>$x</a> ";
} // end else
} // end if
} // end for
// if not on last page, show forward and last page links
if ($page != $total_pages) {
// get next page
$next = $page + 1;
// echo forward link for next page
echo " <a href='search2.php?page=$next'><b>»</b></a> ";
// echo forward link for lastpage
echo " <a href='search2.php?page=$total_pages'><b>Last</b></a> ";
} // end if
/****** end build pagination links ******/
echo " <font size='4' color=white>Total Records</font> <font size='5' color=yellow><b>$number</b></font>";
echo '</table>';
?>
not sure what I need to put in the echo " <a href='search2.php?page=$next'><b>»</b></a> "; in order to call the terms
thanks

Does this not work?
...
$start_from=$page*15
$query = mysql_query("SELECT * FROM cdrequests WHERE ...");
$all_rows = mysql_num_rows($query);
$totalPages = ceil($all_rows/15)-1; #How many pages?
$sql = $query . " LIMIT $start_from,15";
print "<font size=\"5\" color=white><b>CD Requests</b></font> </P>";
print "<table class=\"table1\..."
$terms= '&term1='.$term1 . '&term2='.$term2 . '&term3='.$term3 . '&term4='.$term4;
if($totalPages>1){
#Paging Starts Now
?>
<div align="center">
<? if ($page > 1) { ?>
Previous
First
<? } ?>
Page <? echo $page; ?> of <? echo $totalPages+1; ?>
<? if ($page < $totalPages) { ?>
Next
Last
</div>
<? } }?>

Make it much easier on yourself. Build the table once.
Apply jQuery Datatables to it
$('#table_id).datatables();
Paging done. It's really that easy! All it requires is jQuery and the DataTables plugin, plus a few lines of CSS. As a bonus, it will filter, sort, limit, and more with just additional line of code per feature required. Plus, it can be styled with Themeroller, making a better looking table than most developers can pull off.
