After spending a few hours implementing paged results to my database query, I need some help implementing a search feature into it.
As a newbie this isn't something I'm completely familiar with. Below is the code for the paged results. If anyone would like to see the project in working form, I can supply the URL.
<?
$db_addr = 'localhost'; // address of MySQL server.
$db_user = '***'; // Username to access server.
$db_pass = '****'; // Password access server.
$db_name = '****'; // Name of database to connect to.
$connect = @mysql_connect("$db_addr", "$db_user", "$db_pass");
if (!($connect)) // If no connect, error and exit().
{
echo("<p>Unable to connect to the database server.</p>");
exit();
}
if (!(@mysql_select_db($db_name))) // If can't connect to database, error and exit().
{
echo("<p>Unable to locate the $db_name database.</p>");
exit();
}
if (!($limit)){
$limit = 10;} // Default results per-page.
if (!($page)){
$page = 0;} // Default page value.
$numresults = mysql_query("SELECT * FROM Products WHERE ProductID LIKE '%". $query ."%'"); // the query.
$numrows = mysql_num_rows($numresults); // Number of rows returned from above query.
if ($numrows == 0){
echo("No results found matching your query - $query"); // bah, modify the "Not Found" error for your needs.
exit();}
$pages = intval($numrows/$limit); // Number of results pages.
// $pages now contains int of pages, unless there is a remainder from division.
if ($numrows%$limit) {
$pages++;} // has remainder so add one page
$current = ($page/$limit) + 1; // Current page number.
if (($pages < 1) || ($pages == 0)) {
$total = 1;} // If $pages is less than one or equal to 0, total pages is 1.
else {
$total = $pages;} // Else total pages is $pages value.
$first = $page + 1; // The first result.
if (!((($page + $limit) / $limit) >= $pages) && $pages != 1) {
$last = $page + $limit;} //If not last results page, last result equals $page plus $limit.
else{
$last = $numrows;} // If last results page, last result equals total number of results.
//escape from PHP mode.
?>
<html>

//Go back into PHP mode.

for ($i=1; $i <= $pages; $i++) // loop through each page and give link to it.
{
$ppage = $limit*($i - 1);
if ($ppage == $page){
echo("<b>$i</b> \n");} // If current page don't give link, just text.
else{
echo("<a href=\"$PHP_SELF?query=$query&page=$ppage&limit=$limit\">$i</a> \n");}

if (!((($page+$limit) / $limit) >= $pages) && $pages != 1) { // If last page don't give next link.
$next_page = $page + $limit;
echo(" <a href=\"$PHP_SELF?query=$query&page=$next_page&limit=$limit\">next</a>\n");}
?>

Thanks for your time
