分頁|顯示
php中文章標題很多的情況下怎樣才能分頁顯示呢?
下面根據本人的體會把主要代碼公開,希望對初學網友有所協助.
$page_size=10;(每頁顯示數量)
$sql='select count(*) as rnt from mydbf';
$sql .= ' order by mytime desc ';
$qh=mysql_query($sql);
$data=mysql_fetch_array($qh);
$nr=$data["cnt"];
$pages=intval($nr/$page_size);
if($nr%$page_size) $pages++;
if(empty($page))
{
$page=1;
$offset=0;
}
else
{
$offset=$page*$page_size-$page_size;
}
?>
<!--
$total = mysql_numrows($qh);
$total=$nr;
echo "<td colspan=3>";
//顯示所有文章
if (!isset($page)){
$page = 0;
}
//分頁開始
$start= $page*$page_size;
$offset=$start;
$totalpage =ceil($total/$page_size);
$pagestr ='[<font color=green>總數</font>]:'.$total;
$pagestr.= " ".($page+1).'/'.$totalpage.'頁'." ";
$xjz1= "<a href=$php_self?";
$sql = 'select mytxt,content_id,clicknum,from mydbf ';
$sql .= ' order by ltime desc limit '.$offset.','.$pageno;
$res = mysql_query($ls_sql, $dbh);
$countloop = 0;
while ($row = mysql_fetch_array($res)) {
....
}
$xjz1= "<a href=$php_self?";
$xjz2=substr($xjz1,8);
?>
<table border="0" width="100%" cellpadding="0" cellspacing="0" height="0">
