Ecshop分页规则，分以下几个步骤
1.点击类别，获取第一页获取默认分类列表数据
2.点击“下一页”，采用ajax调取分页内容
实例分析（比如订单列表分页admin/order.php）
1.先写一个function order_list() 模块，里面要包括可以进行排序，分页，查询等功能
2.在order.php里面写一个elseif ($_REQUEST[\'act\'] == \'list\') ，这里是显示默认分页数据
3.在order.php写一个query（listtable.js默认的是先读取$_REQUEST[\'act\'] == \'query\'）排序、分页、查询都在query里面完成
4.html页面（默认order_list.html完整代码）
实战 ”微仓功能“
1.我先写一个function depot_log_list,可以进行排序、分类、查询。这个function里面很有讲究的
重点代码
function depot_list() { //*f.获取上一次保存的查询条件（如果上一次有进行查询过，则直接从f开始） $result = get_filter(); if ($result === false) { // a.查询条件 $filter[\'goods_id\'] = empty($_REQUEST[\'goods_id\']) ? \'\' : trim($_REQUEST[\'goods_id\']); //b.记录总条数 $filter[\'record_count\'] = $GLOBALS[\'db\']->getOne("SELECT COUNT(*) FROM " . $GLOBALS[\'ecs\']->table(\'depot_log\') . $ex_where); //c.分页大小 $filter = page_and_size($filter); //d.查询的sql $sql = "SELECT * FROM " . $GLOBALS[\'ecs\']->table(\'depot_log\') . $ex_where . " order by createtime desc LIMIT " . $filter[\'start\'] . \',\' . $filter[\'page_size\']; //e.保存查询条件（cookie保存） set_filter($filter, $sql); } else { //*f.获取上一次保存的查询条件（如果没有进行查询过，则从a查询。） sql=" role="presentation" style="position: relative;">sql=sql=sql = result[\'sql\']; filter=" role="presentation" style="position: relative;">filter=filter=filter = result[\'filter\']; } $depot_list = $GLOBALS[\'db\']->getAll($sql); //g.组合成系统默认查询条件 $arr = array(\'depot_list\' => $depot_list, \'filter\' => $filter, \'page_count\' => $filter[\'page_count\'], \'record_count\' => $filter[\'record_count\']); return $arr; }
e.f这两步骤非常的重要，还有if($result===false){}也非常重要
实例代码
function depot_list() { $result = get_filter(); if ($result === false) { $filter[\'user_id\'] = empty($_REQUEST[\'user_id\']) ? \'\' : trim($_REQUEST[\'user_id\']); $filter[\'goods_stock\'] = empty($_REQUEST[\'goods_stock\']) ? \'\' : intval($_REQUEST[\'goods_stock\']); $filter[\'sort_by\'] = empty($_REQUEST[\'sort_by\']) ? \'goods_stock\' : trim($_REQUEST[\'sort_by\']); // js的listTable.sort排序功能，也可以user_id $filter[\'sort_order\'] = empty($_REQUEST[\'sort_order\']) ? \'DESC\' : trim($_REQUEST[\'sort_order\']); $ex_where = \' WHERE 1 \'; $ex_where .=" AND user_id = \'$filter[user_id]\' "; $filter[\'record_count\'] = $GLOBALS[\'db\']->getOne("SELECT COUNT(*) FROM " . $GLOBALS[\'ecs\']->table(\'depot\') . $ex_where); /* 分页大小 */ $filter = page_and_size($filter); $sql = "SELECT * FROM " . $GLOBALS[\'ecs\']->table(\'depot\') . $ex_where . " ORDER by " . $filter[\'sort_by\'] . \' \' . $filter[\'sort_order\'] . " LIMIT " . $filter[\'start\'] . \',\' . $filter[\'page_size\']; // $filter[\'keywords\'] = stripslashes($filter[\'keywords\']); set_filter($filter, $sql); } else { $sql = $result[\'sql\']; $filter = $result[\'filter\']; } $depot_list = $GLOBALS[\'db\']->getAll($sql); foreach($depot_list as $k=>$v){ $sql = "SELECT goods_name,goods_thumb from ".$GLOBALS[\'ecs\']->table(\'goods\')." where goods_id = ".$v[\'goods_id\']; $re = $GLOBALS[\'db\']->getRow($sql); $depot_list[$k][\'name\'] = $re[\'goods_name\']; $depot_list[$k][\'goods_thumb\'] = $re[\'goods_thumb\']; } $arr = array(\'depot_list\' => $depot_list, \'filter\' => $filter, \'page_count\' => $filter[\'page_count\'], \'record_count\' => $filter[\'record_count\']); return $arr; }
2.写一个列表
实例代码
elseif($_REQUEST[\'act\'] == \'depot_log\'){ $smarty->assign(\'ur_here\', \'个人微仓操作记录\'); $depot = depot_log_list(); //print_r($depot); $smarty->assign(\'depot_log\', $depot[\'depot_list\']); $smarty->assign(\'filter\', $depot[\'filter\']); $smarty->assign(\'record_count\', $depot[\'record_count\']); $smarty->assign(\'page_count\', $depot[\'page_count\']); $smarty->assign(\'full_page\', 1); assign_query_info(); $smarty->display(\'depot_log_list.htm\'); }
3.写一个列表查询（这里的depot_log_query ，还可以承接html页面的<a href="javascript:listTable.sort(\'goods_stock\', \'DESC\'); ">）
/*会员微仓 ajax 翻页调用*/ elseif ($_REQUEST[\'act\'] == \'depot_list_query\'){ $depot = depot_list(); //$depot = user_list(); $smarty->assign(\'depot\', $depot[\'depot_list\']); $smarty->assign(\'filter\', $depot[\'filter\']); $smarty->assign(\'record_count\', $depot[\'record_count\']); $smarty->assign(\'page_count\', $depot[\'page_count\']); $sort_flag = sort_flag($depot[\'filter\']); $smarty->assign($sort_flag[\'tag\'], $sort_flag[\'img\']); make_json_result($smarty->fetch(\'depot_list.htm\'), \'\', array(\'filter\' => $depot[\'filter\'], \'page_count\' => $depot[\'page_count\'])); // 注意此处的结构，缺少mke_json_result不行 }
4.html页面html代码
<table cellpadding="3" cellspacing="1">
<tr>
<th width="80">
<input onclick=\'listTable.selectAll(this, "checkboxes")\' type="checkbox">
{$lang.record_id}{$sort_user_id}
</th>
<th width="60">缩略图</th>
<th>商品名称</th>
<th><a href="javascript:listTable.sort(\'order_amount\', \'DESC\'); ">库存</a></th>
<th>{$lang.handler}</th>
<tr>
{foreach from=$depot item=vo}
<tr>
<td><input type="checkbox" name="checkboxes[]" value="{$vo.id}" notice="{if $user.user_money ne 0}1{else}0{/if}"/>{$vo.id}</td>
<td class="first-cell"><a href="../goods.php?id={$vo.id}" target="_blank"><img src="../{$vo.goods_thumb}" width=40 style="border: 1px solid #eee"/></a></td>
<td><span onclick="listTable.edit(this, \'edit_email\', {$user.user_id})"><a href="../goods.php?id={$vo.id}" target="_blank">{$vo.goods_name}</a></span></td>
<td align="center">{$vo.goods_stock}</td>
<td align="center">
<a href="users.php?act=depot_log&user_id={$vo.user_id}&goods_id={$vo.goods_id}" title="查看记录"><img src="images/icon_view.gif" border="0" height="21" width="21" /></a>
</td>
</tr>
{foreachelse}
<tr><td class="no-records" colspan="11">{$lang.no_records}</td></tr>
{/foreach}
<tr>
<td colspan="2">
<input type="hidden" name="act" value="batch_remove" />
<input type="submit" id="btnSubmit" value="{$lang.button_remove}" disabled="true" class="button" /></td>
<td align="right" nowrap="true" colspan="9">
{include file="page.htm"}
</td>
</tr>
</table>
js代码
{if $full_page}
</div>
<!-- end users list -->
</form>
<script type="text/javascript" language="JavaScript">
<!--
listTable.recordCount = {$record_count};
listTable.pageCount = {$page_count};
{foreach from=$filter item=item key=key}
listTable.filter.{$key} = \'{$item}\';
{/foreach}
{literal}
onload = function()
{
//document.forms[\'searchForm\'].elements[\'keyword\'].focus();
// 开始检查订单
startCheckOrder();
//a.listtable.js默认是listTable.query="query"，也就是order.php页面的elseif ($_REQUEST[\'act\'] == \'query\')
如果不想只想默认的$_REQUEST[\'act\']==\'query\',就需要写上以下代码
listTable.query = "depot_list_query"; 默认载入使用（第一次点击列表）
}
/**
* 搜索用户
*/
function searchUser()
{
//listTable.filter[\'keywords\'] = Utils.trim(document.forms[\'searchForm\'].elements[\'keyword\'].value);
listTable.filter[\'page\'] = 1;
// b.与a作用一样
listTable.query = "depot_list_query"; 承接上一次查询条件
listTable.loadList();
}
//-->
</script>
{/literal}
{include file="pagefooter.htm"}
{/if}
如果改变了，默认的query查询；则a,b两处都不可以少
分页实例化结构代码
Array ( [depot_list] => Array ( [0] => Array ( [id] => 1 [user_id] => 1 [goods_id] => 2 [goods_stock] => 2 [goods_name] => 荷兰Nutrilon牛栏奶粉 ) [1] => Array ( [id] => 7 [user_id] => 1 [goods_id] => 6 [goods_stock] => 4 [goods_name] => 1111 ) ) [filter] => Array ( [user_id] => 1 [record_count] => 2 [page_size] => 4 [page] => 1 [page_count] => 1 [start] => 0 ) [page_count] => 1 [record_count] => 2 )
