I have a mysql keyword search on my website and it works fine. The problem is when someone searches a keyword I haven't added, nothing shows up on the results page. Instead of nothing showing up I would like to have a no results were found message. I was told I have to use this code:


<?php
if (mysql_num_rows($rs_main) == 0) {
echo "No records found.";
}
?>
But I've been trying to implement that code within my code for the last couple of days and for some reason I can't get it to work. It would greatly appreciated if someone could show me where and how to properly implement the code above within my code to solve my problem, thanks in advance.

Here's my code so you can better understand my problem


<?php
function buildNavigation($pageNum_Recordset1,$tot… | ",$max_links=10, $show_page=true)
{
GLOBAL $maxRows_Recordset1,$totalRows_Recordset…
$pagesArray = ""; $firstArray = ""; $lastArray = "";
if($max_links<2)$max_links=2;
if($pageNum_Recordset1<=$totalPages_R… && $pageNum_Recordset1>=0)
{
if ($pageNum_Recordset1 > ceil($max_links/2))
{
$fgp = $pageNum_Recordset1 - ceil($max_links/2) > 0 ? $pageNum_Recordset1 - ceil($max_links/2) : 1;
$egp = $pageNum_Recordset1 + ceil($max_links/2);
if ($egp >= $totalPages_Recordset1)
{
$egp = $totalPages_Recordset1+1;
$fgp = $totalPages_Recordset1 - ($max_links-1) > 0 ? $totalPages_Recordset1 - ($max_links-1) : 1;
}
}
else {
$fgp = 0;
$egp = $totalPages_Recordset1 >= $max_links ? $max_links : $totalPages_Recordset1+1;
}

for($a = $fgp+1; $a <= $egp; $a++){
$theNext = $a-1;

{

} else {
$min_l = (($a-1)*$maxRows_Recordset1) + 1;
