PHP通過從數據庫的分頁表中排序

Question

我知道它是爲了排序，但現在頁面無法正常工作。現在沒有什麼打印到我的error_logs中。

用戶紅酸幫助我們解決了遺漏的空白問題，並使用字符串變量而不是PHP_SELF。

一旦我按下下一個記錄，我得到：

未找到

請求的URL /surf/$index.php此服務器上找到。

此外，在嘗試 使用ErrorDocument來處理請求時遇到404未找到錯誤。

我的代碼：

       $dbHost = "localhost"; 
       $dbUser = ""; 
       $dbPass = ""; 
       $dbName = "";

       $rec_limit = 20; 
       $order = "ORDER BY"; 
       $scriptname = 'index.php'; 

       mysql_connect("$dbHost", "$dbUser", "$dbPass")or die("cannot connect"); 
       mysql_select_db("$dbName")or die("cannot select DB");

Answer 1

的問題，你沒有順序之間和DESC空白：

$sql="SELECT * FROM $tbl_name ORDER BY ".$_GET["orderby"].$_GET["desc"]; 

應該是：

$sql="SELECT * FROM $tbl_name ORDER BY ".$_GET["orderby"]." ".$_GET["desc"]; 

使用字符串變量代替的PHP_SELF：

$scriptname = 'myscript.php'; // OR http://domain.com/myscript.php 
echo "<a href=\"$scriptname?page=$last\">Last 10 Records</a>";
