分頁和序列號php mysql

你好，我有以下代碼序列號。和分頁。分頁正在工作，但當我轉到下一頁時，序列號從1開始。我在每頁中限制了10行，所以我想從SN開始下一頁。從第3頁開始11-20,21-30。請幫幫我。分頁和序列號php mysql

請注意，沒有訂單的限制是相當無意義的 – Strawberry

只動$sn初始化如果條件

$start=0; 
$limit=10; 

if(isset($_GET['mainmdsid'])) 
{ 
    $mainmdsid=$_GET['mainmdsid']; 
    $start=($mainmdsid-1)*$limit; 
} 
else{ 
    $mainmdsid=1; 
} 
$sn=$start;

謝謝，真的非常有幫助。 –

在點擊每關下一頁按鈕，增加限制$start從0到+10。並再次調用您的數據庫查詢，並且將前一個按鈕遞減值$start設置爲-10。並且還使用變量currentPage並在開始時將其值設置爲1。

下面是示例代碼，您可以使用：

$currentPage = 1; 
$start = 0; 
$recordPerPage= 10; 

//First query your database here, after that do some work on previous and next button clicked 

if(array_key_exists('next',$_POST)){ 
    $start = (currentPage * recordPerPage) + 1; 
    currentPage++; 
} 
if(array_key_exists('previous',$_POST)){ 
    if (currentPage == 2) { 
     offSet = 0; 
     currentPage--; 
    } else { 
     offSet = offSet - recordPerPage; 
     currentPage--; 
    } 
}

這種方式可以處理當前頁面，限制和抵消。記得在點擊下一個和上一個按鈕時調用數據庫查詢
