Question

比如：进入页面后显示有6页，当我点击到第三页或者别的页的时候，我在关键字搜索框里输入条件，点击查询后，显示共有2页内容，当前为第三页。当我往前翻页的时候，查询出的数据都没有错。翻页之后就显示正常了，共2页，当前为1页或者2页。这是怎么回事啊。
$rizhiziduan = isset($_POST['rizhiziduan'])?$_POST['rizhiziduan']:(isset($_GET['rizhiziduan'])?$_GET['rizhiziduan']:"");
$txt_ss = isset($_POST['txt_ss'])?$_POST['txt_ss']:(isset($_GET['txt_ss'])?$_GET['txt_ss']:"");    
    
//输出表头
echo "<table  border=1 width=700 cellspacing=0 style=border-collapse:collapse>"; 
echo "<tr style=background-image:url(img/new_hader_27.jpg) height=30 style=color:#ffffff><th>hotel_id</th><th>name</th><th>content</th><th>operating</th><th>time</th></tr>"; 
//查询数据
if( empty($rizhiziduan) || empty($txt_ss))
    $query1 = "SELECT * FROM hotel_rizhi";
else
    $query1 = "SELECT * FROM hotel_rizhi where $rizhiziduan like '%{$txt_ss}%'"; //在mytable表上执行SQL语句 
    
$result1=mysql_query($query1) or die("<script>alert('查询的数据不存在');window.location='chaxun_rizhi.php';</script>"); 
$rowsPerPage=5;
$row = mysql_fetch_assoc($result1); 
$numrows=$row[0]; 
$pages=intval($numrows/$rowsPerPage); 
if ($numrows%$rowsPerPage) 
$pages++;
$maxRowCount=mysql_num_rows($result1);if($maxRowCount%$rowsPerPage==0){
    $maxPage=(int)($maxRowCount/$rowsPerPage);

Answer 1

$maxRowCount=mysql_num_rows($result1);
if($maxRowCount%$rowsPerPage==0){
    $maxPage=(int)($maxRowCount/$rowsPerPage);
}else {
    $maxPage=(int)($maxRowCount/$rowsPerPage)+1;
}
改成
$maxPage = $pages;
}[/code]

Answer 2

这就是按照你那个改的 ，搜索不了
