实现Ecshop商品跳到淘宝、京东等的购买链接

今天简单的实现了一下ecshop商品导出到第三方的购买链接功能。
大致思路是给商品添加一个buy_link的text字段，存为json结构，然后通过json解析输出到商品购买页面

1.添加字段

增加购买链接字段，执行sql语句：

1	ALTER TABLE `ecs_goods` ADD `buy_link` TEXT NULL AFTER `goods_thumb` ;

2.增加商品发布表单项

随意增加

1

<tr>

2	<td class="label">购买链接</td>

3	<td><textarea name="buy_link" cols="40" rows="3">{$goods.buy_link}</textarea></br>

4	使用了简单json结构，请严格按照格式填写(如:{'taobao':'http://','360buy':'http://'},</br>分别代表淘宝店和京东店内的购买连接)

5

</td>

6

7

</tr>

到/admin/templates/goods_info.htm,我增加在第258行下面(即，第三个table最后注意不要破坏table结构)

后台商品编辑页面多出了一个项目

3.增加读取数据

因为涉及到数据更新，应该先给表单填写初始值。在/admin/goods.php 446行下增加

1	$smarty->assign('buy_link',$goods['buy_link']);

4.增加发布商品存库

编辑/admin/goods.php页面821开始。取得表单传值buy_link，并在insert语句中增加中字段buy_link。可以直接修改为

1	$goods_thumb = (empty($goods_thumb) && isset($_POST['auto_thumb']))? $goods_img :$goods_thumb;

2	$buy_link = empty($_POST['buy_link']) ? '' : trim($_POST['buy_link']);

3

4

/* 入库 */

5	if ($is_insert)

6

{

7	if ($code == '')

8

{

9	$sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, " .

10	"cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " .

11	"promote_start_date, promote_end_date, goods_img, goods_thumb, buy_link, original_img, keywords, goods_brief, " .

12	"seller_note, goods_weight, goods_number, warn_number, integral, give_integral, is_best, is_new, is_hot, " .

13	"is_on_sale, is_alone_sale, is_shipping, goods_desc, add_time, last_update, goods_type, rank_integral, suppliers_id)" .

14	"VALUES ('$_POST[goods_name]', '$goods_name_style', '$goods_sn', '$catgory_id', " .

15	"'$brand_id', '$shop_price', '$market_price', '$is_promote','$promote_price', ".

16	"'$promote_start_date', '$promote_end_date', '$goods_img', '$goods_thumb', '$buy_link', '$original_img', ".

17	"'$_POST[keywords]', '$_POST[goods_brief]', '$_POST[seller_note]', '$goods_weight', '$goods_number',".

18	" '$warn_number', '$_POST[integral]', '$give_integral', '$is_best', '$is_new', '$is_hot', '$is_on_sale', '$is_alone_sale', $is_shipping, ".

19	" '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$rank_integral', '$suppliers_id')";

20

}

21

else

22

{

23	$sql = "INSERT INTO " . $ecs->table('goods') . " (goods_name, goods_name_style, goods_sn, " .

24	"cat_id, brand_id, shop_price, market_price, is_promote, promote_price, " .

25	"promote_start_date, promote_end_date, goods_img, goods_thumb, buy_link, original_img, keywords, goods_brief, " .

26	"seller_note, goods_weight, goods_number, warn_number, integral, give_integral, is_best, is_new, is_hot, is_real, " .

27	"is_on_sale, is_alone_sale, is_shipping, goods_desc, add_time, last_update, goods_type, extension_code, rank_integral)" .

28	"VALUES ('$_POST[goods_name]', '$goods_name_style', '$goods_sn', '$catgory_id', " .

29	"'$brand_id', '$shop_price', '$market_price', '$is_promote','$promote_price', ".

30	"'$promote_start_date', '$promote_end_date', '$goods_img', '$goods_thumb', '$buy_link', '$original_img', ".

31	"'$_POST[keywords]', '$_POST[goods_brief]', '$_POST[seller_note]', '$goods_weight', '$goods_number',".

32	" '$warn_number', '$_POST[integral]', '$give_integral', '$is_best', '$is_new', '$is_hot', 0, '$is_on_sale', '$is_alone_sale', $is_shipping, ".

33	" '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$code', '$rank_integral')";

34

}

35

}

,这样 增加商品时就能指定buy_link了

5.增加修改商品存库

在/admin/goods.php 901 行上的sql拼接上增加

1	"buy_link = '$buy_link', " .

则变为

1	$sql .= "buy_link = '$buy_link', " .

2	"keywords = '$_POST[keywords]', " .

3	"goods_brief = '$_POST[goods_brief]', " .

4	"seller_note = '$_POST[seller_note]', " .

5	"goods_weight = '$goods_weight'," .

6	"goods_number = '$goods_number', " .

7	"warn_number = '$warn_number', " .

8	"integral = '$_POST[integral]', " .

9	"give_integral = '$give_integral', " .

10	"rank_integral = '$rank_integral', " .

11	"is_best = '$is_best', " .

12	"is_new = '$is_new', " .

13	"is_hot = '$is_hot', " .

14	"is_on_sale = '$is_on_sale', " .

15	"is_alone_sale = '$is_alone_sale', " .

16	"is_shipping = '$is_shipping', " .

17	"goods_desc = '$_POST[goods_desc]', " .

18	"last_update = '". gmtime() ."', ".

19	"goods_type = '$goods_type' " .

20	"WHERE goods_id = '$_REQUEST[goods_id]' LIMIT 1";

由此，数据入库基本完成，现在做模版赋值。

6.模版赋值

goods_info函数已经读取出来所有数据，因此直接修改/goods.php( 注：是根目录下的),在197行下增加

1	/*第三方购买链接*/

2

3	//不是json数据则不予赋值,防止编辑格式错误致使前台js解析出错

4

5	if(is_null(json_decode($goods['buy_link']))){

6

7	$smarty->assign('buy_link',$goods['buy_link']);

8

9

}

7.模版读取

修改商品详情模版，如/themes/default/goods.dwt。397行下增加

1	<!-- {* 第三方购买 *} -->

2	<!-- {if $buy_link != ""} -->

3	<script type="text/javascript" language="javascript">

4

5	var text="";

6

7	// if(isJSONText){

8	Jbuylink = eval("{$buy_link}");

9	for(i=0;i<Jbuylink.length;i++){

10	text +='<a href="'+Jbuylink[i].url+'"target="_blank">'+Jbuylink[i].text+'</a>&nbsp;';

11

}

12	document.write("<br/>"+text);

13

// }

14

15

</script>

16	<!-- {/if} -->

ok,功能完成。

下面简单测试下：编辑任意商品buy_link属性为[{text:'淘宝购买',url:'http://taobao.com'},{text:'京东购买',url:'http://360buy.com?p=89899'}]         保存，查看页面，如图：

商品导出连接

由此，已经能够读取到导出链接了

第4步中的内容改为

1

<tr>

2	<td class="label">购买链接</td>

3	<td><textarea name="buy_link" cols="40" rows="3">{$goods.buy_link}</textarea></br>

4	请严格按照格式填写(如:[{text:'淘宝购买',url:'http://taobao.com'},{text:'京东购买',url:'http://360bu.com'}]  </br>分别代表淘宝店和京东店内的购买连接)
