把持ECSHOP的购置数目，在非常多时分是必需的，并且当你有特殊的需求的时分，把持数目显得非分特别主要。需求在goods表中增加个字段"gc"把持购置数目 起首，你需求在购置的时分，提醒输出框,通知用户,你必需购置几多.其次,购物车中需求修正购置数目的时分，你也需求把持。 1:具体页面中把持. 在flow.php外面addto_cart中,参加以下代码,把持购置. $gc = $db -> getOne("select gc from ".$ecs->table(&＃39;goods&＃39;)." where goods_id = ".$goods ->goods_id); if ($goods->number%$gc) { $result[&＃39;error&＃39;] = 1; $result[&＃39;message&＃39;] = "购置数目必需输出{$gc}的倍数"; } 2:在common.js中增加函数 function addToCart1(goodsId, parentId) { var goods        = new Object(); var spec_arr     = new Array(); var fittings_arr = new Array(); var number    = 1; var t = "number"+goodsId; number = document.getElementById("number"+goodsId).value; goods.spec     = spec_arr; goods.goods_id = goodsId; goods.number = number; goods.parent = (typeof(parentId) == "undefined") ? 0 : parseInt(parentId); Ajax.call(&＃39;flow.php?step=add_to_cart&＃39;, &＃39;goods=&＃39; + goods.toJS**tring(), addToCartResp**e, &＃39;POST&＃39;, &＃39;JSON&＃39;); } 2:把持列表页面的购置. 在列表页面中，增加一个框. <form action="Javascript:addToCart1({$goods.goods_id})" method="post" name="ECS_FORMBUY{$goods.goods_id}" id="ECS_FORMBUY{$goods.goods_id}" >   购置数目：<input name="number{$goods.goods_id}" type="text" id="number{$goods.goods_id}" value="1" size="4"   class="formBorder"/><br />     <a href="Javascript:addToCart1({$goods.goods_id})"><img src="images/but_buy.jpg"></a> <a href="Javascript:;" id="compareLink"quotes"}&＃39;,&＃39;{$goods.type}&＃39;)"><img src="images/but_comp.jpg"></a></form> 挪用addToCart1函数. 3:引荐页面 在common.js中增加函数addToCart2 function addToCart2(goodsId, parentId) { var goods        = new Object(); var spec_arr     = new Array(); var fittings_arr = new Array(); var number    = 1; var t = "number"+goodsId; number = document.getElementById("number_"+goodsId).value; goods.spec     = spec_arr; goods.goods_id = goodsId; goods.number = number; goods.parent = (typeof(parentId) == "undefined") ? 0 : parseInt(parentId); Ajax.call(&＃39;flow.php?step=add_to_cart&＃39;, &＃39;goods=&＃39; + goods.toJS**tring(), addToCartResp**e, &＃39;POST&＃39;, &＃39;JSON&＃39;); } 在recommend_new.lbi,recommend_best.lbi等页面中，需求增加输出框.挪用次函数. <form action="Javascript:addToCart2({$goods.id})" method="post" name="ECS_FORMBUY_{$goods.id}" id="ECS_FORMBUY_{$goods.id}" >   购 买数目：<input name="number_{$goods.id}" type="text" id="number_{$goods.id}" value="1" size="4"   class="formBorder"/><br /><a href="Javascript:addToCart2({$goods.id})"><img src="images/but_buy.jpg"></a></form> 最初完成了购置数目的把持。
