ecshop后台默认没有给商品设置最小起订量或者最少购买量的功能。保哥在使用ecshop做一个商城时,要给商品设置包邮来吸引买家,但又不想买家购买一件产品也给包邮,这样很容易亏本。对于价值较高的商品有一定的利润空间设置包邮是合情合理的,但是有的商品价格都低于运费了,就不能再包邮了。有的朋友可能会说,可以发布商品属性价格,不同数量装的价格或者发布商品时,设置十个装的价格,但是这样的话,买家一眼看到商品上显示的价位太高,可能心理上就不愿意再看了。我们设置一件商品的价格,这样在心理上感觉便宜。具体的解决思路是可以给ecshop在下订单设置一个强制提示最小购买数量。具体的解决步骤如下:
编辑/themes/goods.dwt文件,找到以下代码:
<input name="number" type="text" id="number" value="1" size="4" onblur="changePrice()" style="border:1px solid #ccc; "/>
替换为以下代码:
<input type="text" id="number" size="4" value="10" style="border:1px solid #ccc; " onkeyup="if(this.value.length > 1 && /^[1-9]d+$/.test(this.value) == false){alert('输入有误,购买数量不少于10个')}" onblur="if(this.value.length == 1)alert('输入有误,购买数量不少于10个');changePrice()"/>
但是这种方法会使得全站所有的商品购买数量都设置为不低于十个,不太人性化。那么下面这种修改数据库的方法,可以在后台产品编辑时,设置每个商品的最小购买数量。具体方法如下:
第一步,给商品表创建一个新字段min_number用于储存每个商品的最小订购数量数据,打开goods表在最后字段添加一个min_number类型为tinyint默认值为0
alter table 'goods' add column 'min_number' tinyint (3) UNSIGNED DEFAULT '0' NOT NULL after 'warn_number'
第二步,在后台添加商品的时候,在text文本框里设置最小起订量,编辑admin/goods.php文件
找到
'warn_number'=> 1 ,
代码行后插入
'min_number'=> 0,
在
$warn_number = isset($_POST['warn_number']) ? $_POST['warn_number'] : 0;
后添加代码
$min_number = isset($_POST['min_number']) ? $_POST['min_number'] : 0;
第三步,修改添加商品sql语句
if ($is_insert){ if ($code == ''){ $sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, " . "cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " . "promote_start_date, promote_end_date, goods_img, goods_thumb, original_img,keywords, goods_brief, " . "seller_note, goods_weight, goods_number, warn_number,min_number, integral,give_integral, is_best, is_new, is_hot, ". "is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type,rank_integral)" . "VALUES ('$_POST[goods_name]', '$goods_name_style', '$goods_sn', '$catgory_id', " . "'$brand_id', '$shop_price', '$market_price', '$is_promote','$promote_price', ". "'$promote_start_date', '$promote_end_date', '$goods_img', '$goods_thumb', '$original_img', ". "'$_POST[keywords]', '$_POST[goods_brief]', '$_POST[seller_note]', '$goods_weight','$goods_number',". "'$warn_number','$min_number', '$_POST[integral]', '$give_integral', '$is_best', '$is_new', '$is_hot', '$is_on_sale', '$is_alone_sale', ". "'$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type','$rank_integral')"; }else{ $sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, ". "cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " . "promote_start_date, promote_end_date, goods_img, goods_thumb, original_img,keywords, goods_brief, " . "seller_note, goods_weight, goods_number, warn_number, min_number,integral,give_integral, is_best, is_new, is_hot, is_real, " . "is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type,extension_code, rank_integral)" . "VALUES ('$_POST[goods_name]', '$goods_name_style', '$goods_sn', '$catgory_id', " . "'$brand_id', '$shop_price', '$market_price', '$is_promote','$promote_price', ". "'$promote_start_date', '$promote_end_date', '$goods_img', '$goods_thumb','$original_img', ". "'$_POST[keywords]', '$_POST[goods_brief]', '$_POST[seller_note]', '$goods_weight','$goods_number',". " '$warn_number','$min_number', '$_POST[integral]', '$give_integral', '$is_best','$is_new', '$is_hot', 0, '$is_on_sale', '$is_alone_sale’' ". " '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$code', '$rank_integral')"; } }else{ $sql = "SELECT goods_thumb, goods_img, original_img " . " FROM " . $ecs->table('goods') . " WHERE goods_id = '$_REQUEST[goods_id]'"; $row = $db->getRow($sql); if ($proc_thumb && $goods_img && $row['goods_img'] && !goods_parse_url($row['goods_img'])) { @unlink(ROOT_PATH . $row['goods_img']); @unlink(ROOT_PATH . $row['original_img']); } if ($proc_thumb && $goods_thumb && $row['goods_thumb'] && !goods_parse_url($row['goods_thumb'])) { @unlink(ROOT_PATH . $row['goods_thumb']); } $sql = "UPDATE " . $ecs->table('goods') . " SET " . "goods_name = '$_POST[goods_name]', " . "goods_name_style = '$goods_name_style', " . "goods_sn = '$goods_sn', " . "cat_id = '$catgory_id', " . "brand_id = '$brand_id', " . "shop_price = '$shop_price', " . "market_price = '$market_price', " . "is_promote = '$is_promote', " . "promote_price = '$promote_price', " . "promote_start_date = '$promote_start_date', " . "promote_end_date = '$promote_end_date', "; if ($goods_img) { $sql .= "goods_img = '$goods_img', original_img = '$original_img', "; } if ($goods_thumb) { $sql .= "goods_thumb = '$goods_thumb', "; } if ($code != '') { $sql .= "is_real=0, extension_code='$code', "; } $sql .= "keywords = '$_POST[keywords]', " . "goods_brief = '$_POST[goods_brief]', " . "seller_note = '$_POST[seller_note]', " . "goods_weight = '$goods_weight'," . "goods_number = '$goods_number', " . "warn_number = '$warn_number', " . "min_number = '$min_number', " . "integral = '$_POST[integral]', " . "give_integral = '$give_integral', " . "rank_integral = '$rank_integral', " . "is_best = '$is_best', " . "is_new = '$is_new', " . "is_hot = '$is_hot', " . "is_on_sale = '$is_on_sale', " . "is_alone_sale = '$is_alone_sale', " . "goods_desc = '$_POST[goods_desc]', " . "last_update = '". gmtime() ."', ". "goods_type = '$goods_type' " . "WHERE goods_id = '$_REQUEST[goods_id]' LIMIT 1"; }
第四步,修改后台模板文件admin/templates/goods_info.htm
在
<tr> <td class="label">{$lang.lab_shop_price}</td> <td><input type="text" name="market_price" value="{$goods.shop_price}" size="20" /> <input type="button" value="{$lang.integral_market_price}" onclick="integral_market_price()" />{$lang.require_field}</td> </tr>
后添加
<!-- 新增 批发数量限制 begin --> <tr> <td class="label">{$lang.lab_min_number}</td> <td><input type="text" name="min_number" value="{$goods.min_number}" size="20" /> <span class="notice-span" {if $help_open}style="display:block" {else} style="display:none" mce_style="display: none;" {/if} id="minNumber">{$lang.notice_min_number}</span> </td> </td> </tr> <!-- 批发数量限制 end -->
第五步:修改语言languages/zh_cn/admin/goods.php
最后添加
$_LANG['lab_min_number'] = '最小购买数量:'; $_LANG['notice_min_number'] = '该商品最小购买数量,0表示按购买数量无限制.'
到现在位置 后台设置全部结束了,不知道大家能懂了没有
前台实现:
以default模板为例,修改themes/default/goods.dwt
<input name="number" type="text" id="number" value="1" size="4" onBlur="changePrice()" style="border:1px solid #ccc; " mce_style="border: 1px solid #ccc;"/>
改成
<input name="number" type="text" id="number" value="{$goods.min_number|default:"1"}" size="4" onblur="changePrice()" style=”border:1px solid #ccc; " mce_style="border: 1px solid #ccc;"/>
这样就是value 也就是默认值了
最后添加JS判断就好了
themes/default/goods.dwt
在
var qty = document.forms['ECS_FORMBUY'].elements['number'].value;
后添加
{if $goods.min_number} if(qty < {$goods.min_number}) { alert('您输入的数字小于此商品最小购买数量:{$goods.min_number}'); qty = {$goods.min_number}; } {/if}
