为什么每页显示数量不一样

本来每页显示数设为10条，但是加上红色部分代码，就会乱掉，有的页显示2条记录，有的页显示3条记录，有的页显示4条记录。。。。。。没有红色部分代码就正常

$sql = "SELECT ck.chuku_id,ck.status,ck.danhao,ck.type,ck.sq_time,ck.bl_time,sq_user.real_name as sq_realname,bl_user.real_name as bl_realname FROM " .

回复讨论(解决方案)

这样基本上看不出什么吧，把分页的罗辑也贴出来看看呢．

$sql_where = ' where ck.school_id=' . $school_id;

if($bl_time_start != '')
{
$sql_where .= " and ck.bl_time>=" . gmstr2time($bl_time_start);
}
if($bl_time_end != '')
{
$sql_where .= " and ck.bl_time<=" . gmstr2time($bl_time_end);
}
if($danhao != '')
{
$sql_where .= " and ck.danhao like '%" . mysql_like_quote($danhao) . "%'";
}

if($type != 0)
{
$sql_where .= " and ck.type=" . $type;
}

if($banzhuren_id != 0)
{
$sql_where .= " and ck.chuku_user_id=" . $banzhuren_id;
}

if($name != '')
{
$sql_where .= " and hp.name like '%" . mysql_like_quote($name) . "%'";
}

//判断是否有权限，如果没有则用户只能查看自己的入库单
if (strpos($_SESSION['action_list'],'oa_churuku_list') === false && strpos($_SESSION['action_list'], 'all') === false){
$sql_qx=" and (ck.chuku_user_id=".$_SESSION['userid']." or ck.jingban_user_id=".$_SESSION['userid']." or ck.check_user_id=".$_SESSION['userid'].") order by ck.chuku_id desc";
}else{
$sql_qx=" order by ck.chuku_id desc";
}

$sql = "SELECT ck.chuku_id,ck.status,ck.danhao,ck.type,ck.sq_time,ck.bl_time,sq_user.real_name as sq_realname,bl_user.real_name as bl_realname FROM " .

}
}

$page = !empty($_REQUEST['p']) && intval($_REQUEST['p']) > 0 ? intval($_REQUEST['p']) : 1;
$size = 10;
$count = get_chuku_count($school_id,$bl_time_start,$bl_time_end,$danhao,$type,$banzhuren_id,$name);
$pages = ($count > 0) ? ceil($count / $size) : 1;
$smarty->assign('count', $count); //记录总数
$smarty->assign('pages', $pages); //总页数
$smarty->assign('chuku_list', get_chuku_list($school_id,$bl_time_start,$bl_time_end,$danhao,$type,$banzhuren_id,$name,$page,$size));
$smarty->assign('pagenavi', get_pagenavi($page,$pages,5));
其中，get_chuku_list()这个函数就是我发的那些代码
