Question

我是分页新手，我尝试过这样做。它部分有效。我的分页，在每页上显示正确的结果数量以及正确的页数。但问题是它在每个页面上显示相同的结果。

以下是代码：

$rows = mysqli_num_rows($result);
echo $rows;
//Total row count.


//Number of results we want displayed per page.
$page_rows = 3;
//Last page, page number.
$last = ceil($rows/$page_rows);
//Making sure that last page cannot be less than one.
if($last < 1){
 $last = 1;
}
//Establish pagenum variable;
$pagenum = 1;
//Get paenum variable from the URL if it exists.
if(isset($_GET['pn'])){
 $pagenum = preg_replace('#[^0-9]#', '', $_GET['pn']);
}
//Making sure the pagenum isn't below one.
if($pagenum < 1){
 $pagenum = 1;
}else if($pagenum > $last){
 $pagenum = $last;
}
//This sets the limit.
$limit =  'LIMIT ' .($pagenum-1) * $page_rows .',' .$page_rows;
//Establish the pagination controls.
$paginationCtrls = '';
//If there is more than one page worth of results.
if($last != 1){
 if($pagenum > 1){
    $previous = $pagenum - 1;
    $paginationCtrls .= '<a href = "'.$_SERVER['PHP_SELF'].'?pn='.$previous.'">Previous</a> &nbsp; &nbsp; ';
    //Clickable links that should appear on the left.
    for($i = $pagenum - 4; $i < $pagenum; $i++){
        if($i > 0){
            $paginationCtrls .='<a href = "'.$_SERVER['PHP_SELF'].'?pn='.$i.'">'.$i.'</a> &nbsp; ';
        }
    }
}
$paginationCtrls .= ''.$pagenum.' &nbsp; ';
for($i = $pagenum+1; $i<= $last; $i++){
    $paginationCtrls .= '<a href="'.$_SERVER['PHP_SELF'].'?pn='.$i.'">'.$i.'</a> &nbsp; ';
    if($i > $pagenum+4){
        break;
    }
}
if($pagenum != $last){
    $next = $pagenum+1;
    $paginationCtrls .= ' &nbsp; &nbsp; <a href="'.$_SERVER['PHP_SELF'].'?pn='.$next.'">Next</a>';
} 
}
$sql = "SELECT * FROM blogdata2 ORDER BY id DESC ".$limit;

我在查询期间也试过这个：

$sql = "SELECT * FROM blogdata2 ORDER BY id DESC $limit";

但似乎都没有用。这可能是什么问题？

感谢您的帮助。
