我有这个php分页类，我想不出一种方法来限制我的SQL查询。这产生的分页按钮很好，但不知道如何限制我的查询输出。另外，我将如何去与我的网址中的其他变量一起使用这个类。因为这一个不支持它，我不认为。喜欢。问题限制我的sql查询与分页类

mypage.php？状态=未决&页= 4

这里是什么在我的 “工作” 页面。

<?php 

require_once('classes/class.paging.php'); 

// PAGINATION STUFF 
$ordercount1 = mysql_query("SELECT * from orders WHERE technumber='$myuserid'"); 
$ordercount2 = mysql_num_rows($ordercount1); 

// echo $ordercount2; 

    $pagingClass = new paging(); 

    $limit = 10;  //Number of rows that we show on page 
    $allRows = $ordercount2; //Number of all rows that we have 

    if(isset($_POST['page'])) { 
     $_GET['page'] = $_POST['page']; 
    } 

    if(!isset($_GET['page']) || !is_numeric($_GET['page'])) { 
     $_GET['page'] = 1; 
    } 

    //We off the page number 
    $pagingClass->showPagesNumber = false; 
    $pagingClass->showPagesForm = false; 
    $pagingClass->numberOfPages = 10; 
    echo $pagingClass->generate('?page=', '', $_GET['page'], $limit, $allRows); 

// END PAGINATION STUFF

限制您的查询？你是什么意思？和url变量有什么问题？最重要的是不要使用'mysql_ *' - 不仅仅是[*弃用*]（http://php.net/manual/en/function.mysql-query.php），而且它还会引用sql_injection。 – alfasin 2012-08-07 03:06:30

限制我的查询，这样我只能显示记录数量，并使其在每个分页页面上相应地移动。 $ getmyorders = mysql_query（“SELECT'orderid'，'status'，'date' FROM orders WHERE technumber ='$ myuserid'ORDER BY date DESC LIMIT $ LIMITER_HERE”）; – 2012-08-07 03:10:52

$ LIMITER_HERE是我所需要的，因为这个类的编码器未能实现我所假设的。 :( – 2012-08-07 03:13:24

您所提供的链接显示用法：

$页=新分页程序;
$ pages-> items_total = $ num_rows [0];
$ pages-> mid_range = 9;
$ pages-> paginate（）;
echo $ pages-> display_pages（）;

在这个例子中9是从你的选择结果的总数，为了找到这个数字（结果的总数）使用分页程序之前使用select count(1) from...。

对于POST/GET参数：你叫过来的参数的分页程序循环，并将它们保存到一个字符串之前：

foreach($_GET as $key=> $val){ $str .= "$key=$val&";}

然后覆盖类每次它创建一个HREF比如，更改：

"href=\"{$_SERVER[PHP_SELF]}?page=$i&ipp=$this->items_per_page\">$i</a> ";

到：

"href=\"{$_SERVER[PHP_SELF]}?" . $str . "page=$i&ipp=$this->items_per_page\">$i</a> ";

我提供的链接就是一个例子。在我的主帖中粘贴的代码是实际使用的类，我想出了SQL限制器，下面是我的解决方案：http：// pastebin。com/qH2La4Mh我仍然好奇如何解决我的主要文章中列出的分页类问题。 – 2012-08-07 03:35:08

我认为你所说的是我需要的，但是我将如何将它实现到上面的分页类（我的主帖子中的第一个代码框），以便它能够工作？而不是您所指的示例链接。 – 2012-08-07 03:48:28

在上面的代码中有一条评论说：*您可以在index.php脚本中找到示例（使用此包）* - 查看这些示例的用法将是一个不错的主意。我做了 – alfasin 2012-08-07 04:07:27
