一、直接在SQL语句上通过limit 的参数
二、全部取出,在结果集数组上通过数组位来控制
其实两种玩法本质上一样
?
//设置当前页显示的数量(这个数量可任意设置)
$limit=20;
//初始化数据库搜索起始记录
if (!empty($start)) $start=0;
mysql_connect("localhost","","");
mysql_select_db(database);
//设置数据库记录总数
$result=mysql_query("select * from table");
$num_max=mysql_numrows($result);
$result=mysql_query("select * from table order by id desc limit $start,$limit);
$num=mysql_numrows($result);
echo "tabletrtd翻页功能/td/tr";
if (!empty($num)) {
for ($i=0;$i$num;$i++) {
$val=mysql_result($result,$i,"val");
$val1=mysql_result($result,$i,"val1");
echo "trtd$val/tdtd$val1/td/tr";
}
}
echo "trtd";
//设置向前翻页的跳转
$prve=$start-$limit;
if ($prve=0) {
echo "a href=page.php?start=$prveprve/a";
}
//设置向后翻页的跳转
$next=$start+$limit;
if ($next$num_max) {
echo "a href=page.php?start=$nextnext/a";
}
echo "/td/tr/table";
?
不是用$_POST[]的,用$_GET[]
不是表单传值,而是链接传值
if( isset($_GET['page']) $_GET['page']!=1){
$page = intval( $_GET['page'] );
$pageSize = 50;
}else{
$page = 1;
$pageSize = 50;
}
if( $page == 0 ){
$link = "a href=?page=".($page+1)."下一页/a";
}
elseif( $page != 0 $page !=1 ){
$link = "本页第 ".$page." 页 a href=?page=1首页/a | a href=?page=".($page-1)."上一页/a | a href=?page=".($page+1)."下一页/a";
}else{
$link = "本页第 ".$page." 页 a href=?page=1首页/a | a href=?page=".($page+1)."下一页/a";
}
那是因为你没有把搜索的参数传过去
你可以写一个隐藏域传递或者直接用搜索的TEXT传过去(再跳转的时候一定要接收到这个关键字,然后把这个关键字再当做搜索框的value值)。然后每次都要用到这个关键字。
也可以把关键字放到session里面,这样就不用传来传去了。但是也是每一次都一定要用这个关键字的
建议你先还是用其他办法作吧!我从phpaaCMS弄了个分页·蛮好的:
?php
include("conn.php");
function selectLimit($sql, $numrows=-1, $offset=-1) {
if($offset==-1){
$sql .= ' LIMIT ' . $numrows;
}else{
$sql .= ' LIMIT ' . $offset . ', ' . $numrows;
}
$res = mysql_query ( $sql );
if ($res !== false) {
$arr = array ();
$row = mysql_fetch_assoc ( $res );
while ($row) {
$arr [] = $row;
$row = mysql_fetch_assoc ( $res );
}
return $arr;
} else {
return false;
}
}
function getArticleList($str=''){
global $db;
$curpage = empty($_GET['page'])?0:($_GET['page']-1);
//定义默认数据
$init_array =array(
'row' =0,
'titlelen' =0,
'keywords' =0,
'type' ='',
'cid' ='',
'order' ='id',
'orderway' ='desc'
);
//用获取的数据覆盖默认数据
$str_array = explode('|',$str);
foreach($str_array as $_str_item){
if(!empty($_str_item)){
$_str_item_array = explode('=',$_str_item);
if(!empty($_str_item_array[0])!empty($_str_item_array[1])){
$init_array[$_str_item_array[0]]=$_str_item_array[1];
}
}
}
//定义要用到的变量
$row = $init_array['row'];
/* $titlelen = $init_array['titlelen'];
$keywords = $init_array['keywords'];

//文章标题长度控制
