hello I try to combine the two scripts from the book PHP 6 and MySQL 5 for Dynamic Web Sites. I did search and pagination, but when I go to the next page - did not work. I posted two screenshots below. if someone could show me how I make a mistake I will be grateful.
<?php require_once("../../includes/functions_2.php"); ?>

//database connect
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "1qazxsw2";
$dbname = "dw_bookstore";
$connection = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);
//sprawdzenie polaczenia
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
//zmaiana znako na utf8
if (!mysqli_set_charset($connection, "utf8")) {
printf("Error loading character set utf8: %s
", mysqli_error($connection));
} else {
//printf("Kodowanie ustawione na: %s
", mysqli_character_set_name($connection));
}
?>

@$query = $_GET['query'];
$query4 = "SELECT COUNT(id) ";
$query4 .= "FROM photographs ";
$query4 .= "WHERE `nazwa` LIKE '%".$query."%' ";
//$query .= "WHERE visible = 1 ";
$result = @mysqli_query ($connection, $query4);
$row = @mysqli_fetch_array ($result, MYSQLI_NUM);
$records = $row[0];
// Count the number of records:
if ($records > $display) { // More than 1 page.
$pages = ceil ($records/$display);
} else {
$pages = 1;
}
