最土团购商品按价格排序实现方法分享

要想实现按价格排序需要前台有链接，后台然后实现相应的功能即可。

前台代码：\include\template\team_multi.html
这个模板文件，因为我们是开启了首页显示多项团购显示，所以用点的这个team_multi.html这个模板

复制代码 代码如下:

<div class=”filter-by-group-title”>按价格:</div>

<div class=”filter-by-group-id”>

<ul class=”cates”>

<li

<!–{if $selector_p == ”}–>

class=”current”

<!–{/if}–>

><a href=”?gid={$_GET[‘gid’]}&areaid={$_GET[‘areaid’]}”>全部</a>

</li>

<li

<!–{if $selector_p == ‘p1’}–>

class=”current”

<!–{/if}–>

><a href=”?gid={$_GET[‘gid’]}&areaid={$_GET[‘areaid’]}&p=p1″>10元以下</a>

</li>

<li

<!–{if $selector_p == ‘p2’}–>

class=”current”

<!–{/if}–>

><a href=”?gid={$_GET[‘gid’]}&areaid={$_GET[‘areaid’]}&p=p2″>10-50元</a>

</li>

<li

<!–{if $selector_p == ‘p3’}–>

class=”current”

<!–{/if}–>

><a href=”?gid={$_GET[‘gid’]}&areaid={$_GET[‘areaid’]}&p=p3″>50-100元</a>

</li>

<li

<!–{if $selector_p == ‘p4’}–>

class=”current”

<!–{/if}–>

><a href=”?gid={$_GET[‘gid’]}&areaid={$_GET[‘areaid’]}&p=p4″>100-200元</a>

</li>

<li

<!–{if $selector_p == ‘p5’}–>

class=”current”

<!–{/if}–>

><a href=”?gid={$_GET[‘gid’]}&areaid={$_GET[‘areaid’]}&p=p5″>200元以上</a>

</li>

</ul>

</div>

</div>

后台代码：\include\function\common.php
index_get_team 函数 修改后的代码

复制代码 代码如下:

function index_get_team($city_id,$group_id=0,$p=””) {

global $INI;

$multi = option_yes(‘indexmulti’);

$city_id = abs(intval($city_id));

/* 是否首页多团,不是则返回当前城市 */

if (!$multi) return current_team($city_id);

$now = time();

$size = abs(intval($INI[‘system’][‘indexteam’]));

/* 侧栏团购数小于1,则返回当前城市数据 */

if ($size<=1) return current_team($city_id);

switch ($p)

{

case “p1”:

$pp1=”team_price < ’10′”;

$pp2=””;

break;

case “p2”:

$pp1=”team_price > ’10′”;

$pp2=”team_price < ’50′”;

break;

case “p3”:

$pp1=”team_price > ’50′”;

$pp2=”team_price < ‘100’”;

break;

case “p4”:

$pp1=”team_price > ‘100’”;

$pp2=”team_price < ‘200’”;

break;

case “p5”:

$pp1=”team_price > ‘200’”;

$pp2=””;

break;

default:

$pp1=””;

$pp2=””;

}

$oc = array(

‘team_type’ => ‘normal’,

“begin_time < ‘{$now}'”,

“end_time > ‘{$now}'”,

);

if(!empty($pp1)){

array_push($oc,$pp1);

}

if(!empty($pp2)){

array_push($oc,$pp2);

}

if($group_id) $oc[‘group_id’]=$group_id;

/* 数据库匹配多个城市订单,前者按照多城市搜索,后者兼容旧字段city_id搜索 */

$oc[] = “(city_ids like ‘%@{$city_id}@%’ or city_ids like ‘%@0@%’) or (city_ids = ” and city_id in(0,{$city_id}))”;

$teams = DB::LimitQuery(‘team’, array(

‘condition’ => $oc,

‘order’ => ‘ORDER BY `sort_order` DESC, `id` DESC’,

‘size’ => $size,

));

if(count($teams) == 1) return array_pop($teams);

return $teams;

}

需要在index.php页面中增加一个
$selector_p=$p=addslashes($_GET[‘p’]);方面当前价格的高亮。

结合以上几点，即可实现最土团购ZuituGo_CV2.0_20111231 商业版的价格排序功能。
