分页
$con = mysql_connect("localhost","root","123456");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("qq", $con);
$result = mysql_query("SELECT * FROM abc");
echo "
qq |
jiage |
lirun |
shijian |
";
while($row = mysql_fetch_array($result))
{
echo "";
echo "" . $row['qq'] . " | ";
echo "" . $row['jiage'] . " | ";
echo "" . $row['lirun'] . " | ";
echo "" . $row['shijian'] . " | ";
echo "
";
}
echo "
";
mysql_close($con);
?>
这是我的代码
可是如果太多信息要拖拽很麻烦,想弄个分页,每个页面显示5条信息
但分页功能不会
谁帮我简单弄下
------解决方案--------------------
header("content-type:text/html;charset=utf-8") ;
mysql_connect("127.0.0.1","root","") or die("连接失败");
mysql_select_db("test");
mysql_query("set names utf8");
if(isset($_GET["pageid"]))
{
$absoultpage=$_GET["pageid"];
}
else
{
$absoultpage=1;
}
$pagesize=2;
$r1=mysql_query("select * from product");
$totalnum=mysql_num_rows($r1);//总的有多少条数据
$totalpage=ceil($totalnum/$pagesize);//总的页数
$sql="SELECT * FROM product limit ".($absoultpage-1) * $pagesize.",$pagesize";
$rs=mysql_query($sql);
echo "
";
while($row = mysql_fetch_row($rs))
{
echo "";
echo "".$row['id']." | ";
echo "".$row['name']." | ";
echo "".$row['price']." | ";
echo "".$row['num']." | ";
echo "".$row['des']." | ";
echo "
";
}
echo "
";
echo "首页";
$PageUp=$absoultpage-1;
if($PageUp < 1)
{
echo "上一页";
}else
{
echo "上一页";
}
$Nextpage=$absoultpage+1;
if($Nextpage > $totalpage)
{
echo "下一页";
}else
{
echo "下一页";
}
echo "尾页";
?>
这个是简单的分页 自己在改改就好了
