我定义了一个类来输出的 下面是类属性...最后是搜索页
include("script/conn.php"); class Page{ private $page; //当前页码 private $page_num; //数据总共分多少页显示 private $page_size; //每页显示的数据条数 private $sql; //查询的SQL语句 private $limit; //查询语句后面的limit控制语句 private $total_Num; //总记录数 public function __construct($sql='',$page_size=3){ $result = mysql_query($sql); $this->total_Num = mysql_num_rows($result); $this->page_size = $page_size; $this->page_num = ceil($this->total_Num / $page_size); //计算总页数 $this->sql = $sql; $temp = (isset($_GET["page"]) ? $_GET["page"] : 1); //获取当前页数 $this->setpage($temp); $this->showpage(); $this->showFoot(); } private function showpage(){ $this->limit = " LIMIT ".(($this->page - 1)* $this->page_size).",".$this->page_size; //limit语句 $result = mysql_query($this->sql.$this->limit); if (!$result){ //判断结果是否存在 if ($this->page_num > 0){ //如果不存在且页数大于0 echo "查询出错"."<br>"; }else{ echo "无数据"."<br>"; } return; } $cols = mysql_num_rows($result); while($row = mysql_fetch_array($result)){ echo "<img src=".$row['Image']." / alt="为什么我的PHP翻页不能翻到下一页呀求教" >"; echo "<br/>"; } } private function setpage($page){ if($page < 1){ $page = 1; } else if($page > $this->page_num){ $page = $this->page_num; } $this->page = $page; } private function showFoot(){ echo "<br/>"; echo "<a href='?page=1'>首页</a>丨"; echo "<a href='?page=".($this->page - 1)."'>上一页</a>丨"; echo "<a href='?page=".($this->page + 1)."'>下一页</a>丨"; echo "<a href='?page=".$this->page_num."'>尾页</a>丨"; echo "共有".$this->page_num."页丨"; echo "当前第".$this->page."页"; } }
翻页时看看 $this->page 是否有变化
搜页后缀没变……如果在类里面执行就变……你有什么办法吗……
翻页时看看 $this->page 是否有变化
搜索页没变后缀～也没有后缀呢……类里面就变……你有什么办法解决吗？还是说要把2我问的是 $this->page 是否有变化
我问的是 $this->page 是否有变化
这个……倒没注意～下课回宿舍试下……不过我估计没变化～
我问的是 $this->page 是否有变化
只能看到首页～也就是第一页……点下一页就数据全无～显示当前第一页……没变化……怎么解决？ 那我要建议你重写了，把数据库操作部分从类中移去
class Page{ private $page; //当前页码 private $page_num; //数据总共分多少页显示 private $page_size; //每页显示的数据条数 private $sql; //查询的SQL语句 private $total_Num; //总记录数 public $limit; //查询语句后面的limit控制语句 public function __construct($total=100, $page_size=3){ $this->total_Num = $total; $this->page_size = $page_size; $this->page_num = ceil($this->total_Num / $page_size); //计算总页数 $temp = (isset($_GET["page"]) ? $_GET["page"] : 1); //获取当前页数 $this->setpage($temp); $this->showpage(); $this->showFoot(); } private function showpage(){ $this->limit = " LIMIT ".(($this->page - 1)* $this->page_size).",".$this->page_size; //limit语句 } private function setpage($page){ if($page < 1){ $page = 1; }else if($page > $this->page_num){ $page = $this->page_num; } $this->page = $page; } private function showFoot(){ echo "<br/>"; echo "<a href='?page=1'>首页</a>丨"; echo "<a href='?page=".($this->page - 1)."'>上一页</a>丨"; echo "<a href='?page=".($this->page + 1)."'>下一页</a>丨"; echo "<a href='?page=".$this->page_num."'>尾页</a>丨"; echo "共有".$this->page_num."页丨"; echo "当前第".$this->page."页"; }}

我问的是 $this->page 是否有变化
$pages = new Page(总数, 每页数);
$pages = new Page(总数, 每页数);
跳转到第二页还是空白。。。是不是我哪里出错了？if($keyword=='桂林'||$keyword=='广西桂林'){ $result=mysql_query("select * from image_guilin limit 3"); while($abc = @mysql_fetch_array($result)){ echo "<img src=".$abc['Image']." / alt="为什么我的PHP翻页不能翻到下一页呀求教" >"; echo "<br/>"; } $pages = new Page(8, 3);}看看 $keyword 是什么
看看 $keyword 是什么
<form id="search_form" method="post" action="abcdefg.php"> <input type="text" id="search" value="城市、景点" onFocus="this.value=''" style="max-width:90%" name="search"/> <input type="submit" id="s_search" value="搜索" name="Submit" onClick="return check(form)"/> </form>
$keyword=$_POST['search'];$sql=mysql_query("select * from didian where name like '%$keyword%'");$row=@mysql_fetch_object($sql);if(!$row){ echo "<font color='red'>您搜索的信息不存在，请使用类似的关键字进行检索!</font>";}
看看 $keyword 是什么
已经解决了，原来是我参数有问题。。谢谢了。
