複製代碼 代碼如下:


/*
mysql_pager.class.php
三個參數。 mysql_query()的結果, url變數page, 您要的每頁記錄數
例子在這個檔案底部
淡水河邊整理測試
*/
class mysql_pager {
// define properties
var $page;
var $result;
var $results_per_page = 3;
var $total_pages;
/*
Define the methods
下面是建構函式,和類同名(>php4)
需要查詢的結果控制代碼,當前頁碼,每頁記錄數
like: $f->mysql_pager($result, 1, 15);
*/
function mysql_pager( $result, $current_page, $results_per_page ) {
if(!$result){
echo "資料庫未運行,結果集錯誤\n";
return;
}
$this->result = $result;
if(!$current_page || $current_page < 0)
$this->page = 1;
else $this->page = $current_page;
if(!emptyempty($results_per_page))
$this->results_per_page = $results_per_page;
$numrows = @mysql_num_rows($this->result);
if(!$numrows) {
echo "查詢結果為空白.\n";
return;
}
$this->total_pages = ceil($numrows / $this->results_per_page);
}
/*
下面是列印內容的函數,可以不用,也可以根據自己的需要擴充
這裡只是列印出id
*/
function print_paged_results() {
echo "











\n"; $start = ($this->page - 1) * $this->results_per_page; mysql_data_seek($this->result, $start); $x = 0; for($i = 1; $i <= $this->results_per_page && $row = @mysql_fetch_array($this->result); $i++) { if($x++ & 1) $bgcolor = "#F2F2FF"; else $bgcolor = "#EEEEEE"; echo " "; // 編輯這部分輸出任何您想要的HTML } echo "
". $row["id"] . "
\n";
}
/*
下面是列印頁碼和連結的函數
在我們需要顯示頁碼的地方調用
*/
function print_navigation() {
global $PHP_SELF;
echo "";
for($i = 1; $i <= $this->total_pages; $i++) { #loop to print << 1 2 3... $total_pages >>
if($i == 1 && $this->page > 1) #Prints the << first to goto the previous page (not on page 1)
echo "page - 1)."\" /a>";
