リストは、他のリストの残りを取得するためのページネーションなしで 10 項目にとどまりました。これはひどいです。最初のコードは機能しましたが、2 番目のコードは機能しましたが、10 個の項目で停止しました。あなたは、私が既に持っていたいくつかのコードで行った ceil を試してみると言いました。 10 の項目が出てきたので、ここで少しイライラし始めています。

                //connect to the database
                $db=mysql_connect ("localhost", "root", "") or die ('I cannot connect to the database    because: ' . mysql_error());

これが変更されたコードの始まりです

//////////pagination////////////

$sql=mysql_query("SELECT userId, FirstName, LastName FROM residentialbackup WHERE     FirstName ='" . $name . "' OR LastName = '" . $name ."'");

//-count results
$numrows=mysql_num_rows($sql);

// Get the value of the last page in the pagination result set
$lastPage = ceil($numrows / $itemsPerPage);

$itemsPerPage = 10;

$page = $_GET['page'];
if (!$page) $page = 1;
$offset = ($page - 1) * $itemsPerPage;

$sql2=mysql_query("SELECT userId, FirstName, LastName FROM residentialbackup WHERE    FirstName = '" . $name . "' OR LastName = '" . $name ."' LIMIT ". $offset . ", ".   $itemsPerPage);

$paginationDisplay = ""; // Initialize the pagination output variable
// This code runs only if the last page variable is ot equal to 1, if it is only 1 page     we require no paginated links to display
if ($lastPage != "1") {
    // This shows the user what page they are on, and the total number of pages
    $paginationDisplay .= 'Page <strong>' . $page . '</strong> of ' . $lastPage. '&nbsp;      &nbsp;  &nbsp; ';
    // If we are not on page 1 we can place the Back button
    if ($page != 1) {
        $previous = $page - 1;
        $paginationDisplay .=  '&nbsp;  <a href="' . $_SERVER['PHP_SELF'] . '?page=' . $previous . '"> Back</a> ';
    } 
    // Lay in the clickable numbers display here between the Back and Next links
$paginationDisplay .= '<span class="paginationNumbers">' . $centerPages . '</span>';
    // If we are not on the very last page we can place the Next button
    if ($page != $lastPage) {
        $nextPage = $page + 1;
        $paginationDisplay .=  '&nbsp;  <a href="' . $_SERVER['PHP_SELF'] . '?page=' .   $nextPage . '"> Next</a> ';
    }

$sql="SELECT userId, FirstName, LastName FROM residentialbackup WHERE FirstName ='" . $name . "' OR LastName = '" . $name ."'";

次のようなページネーションを作成できます。

$itemsPerPage = 10;
$page = $_GET['page'];
if (!$page) $page = 1;
$offset = ($page - 1) * $itemsPerPage;

$sql="SELECT userId, FirstName, LastName FROM residentialbackup WHERE FirstName = '" . $name . "' OR LastName = '" . $name ."' LIMIT ". $offset . ", ". $itemsPerPage;
