添加重复区域后、升序、不用分页
回复讨论(解决方案)
如果是在数据库里读取的话，先desc一下 然后limit取前五十条就好了啊
select * from table desc order by id limit 0,49
要是还想升序排列 可以select * from (select * from table order by id desc limit 0,49 ) order by id asc
$currentPage = $_SERVER["PHP_SELF"];
$maxRows_R1 = 10;
$pageNum_R1 = 0;
if (isset($_GET['pageNum_R1'])) {
$pageNum_R1 = $_GET['pageNum_R1'];
}
$startRow_R1 = $pageNum_R1 * $maxRows_R1;
$maxRows_R1 = 35;
$pageNum_R1 = 0;
if (isset($_GET['pageNum_R1'])) {
$pageNum_R1 = $_GET['pageNum_R1'];}
$startRow_R1 = $pageNum_R1 * $maxRows_R1;
mysql_select_db($database_liandb, $liandb);
$query_R1 = "SELECT * FROM mydb1 ORDER BY id ASC";
$query_limit_R1 = sprintf("%s LIMIT %d, %d", $query_R1, $startRow_R1, $maxRows_R1);
$R1 = mysql_query($query_limit_R1, $liandb) or die(mysql_error());
$row_R1 = mysql_fetch_assoc($R1);
我应该怎么加进去哪？
$query_R1 = "SELECT * FROM mydb1 ORDER BY id desc";
$query_limit_R1=sprintf("%s LIMIT %d, %d", $query_R1, $startRow_R1, $maxRows_R1);
$query_limit_R1_Supper ="select * from (".$query_limit_R1.") order by id asc "
$R1 = mysql_query($query_limit_R1_Supper, $liandb) or die(mysql_error());
$row_R1 = mysql_fetch_assoc($R1);
$query_limit_R1引号可能是少加了。如果不好用你调试一下
$pageNum_R1 = $_GET['pageNum_R1'];}
$startRow_R1 = $pageNum_R1 * $maxRows_R1;
mysql_select_db($database_liandb, $liandb);
$query_R1 = "SELECT * FROM mydb1 ORDER BY id DESC";
$query_limit_R1 = sprintf("%s LIMIT %d, %d", $query_R1, $startRow_R1, $maxRows_R1);
$query_limit_R1_Supper ="select * from (".$query_limit_R1.") order by id asc ";
$R1 = mysql_query($query_limit_R1, $liandb) or die(mysql_error());
$row_R1 = mysql_fetch_assoc($R1);
这样是降序了，升序不起作用了。
错了。。。
$R1 = mysql_query($query_limit_R1_Supper, $liandb) or die(mysql_error());
里面不是$query_limit_R1
麻烦帮我详细的填一下呗，我这菜鸟、谢谢

这两行中间那行删除了？
$query_limit_R1=sprintf("%s LIMIT %d, %d", $query_R1, $startRow_R1, $maxRows_R1);
$query_limit_R1_Supper ="select * from (".$query_limit_R1.") order by id asc "
$R1 = mysql_query($query_limit_R1_Supper, $liandb) or die(mysql_error());
中间那行呢
$pageNum_R1 = $_GET['pageNum_R1'];}
$startRow_R1 = $pageNum_R1 * $maxRows_R1;
mysql_select_db($database_liandb, $liandb);
$query_R1 = "SELECT * FROM mydb1 ORDER BY id DESC";

$R1 = mysql_query($query_limit_R1_Supper, $liandb) or die(mysql_error());
$row_R1 = mysql_fetch_assoc($R1);
错误提示：每一个派生表必须有自己的别名

有一个错误在您的SQL语法;检查手册,对应你的MySQL服务器版本为正确的语法使用附近的订单id asc在1号线
$query_limit_R1_Supper ="select M.* from (".$query_limit_R1.") M, order by id asc ";
还是一样的错误

应该是多加了个逗号。。非常抱歉
这回好了，感谢你的耐心帮助，可是不知道怎么选精彩回答？
