创建会议门票的代码如下。
1 // 创建会议/演出门票
2 $data = array('card_type' => "MEETING_TICKET",
3 'meeting_ticket' => array('base_info' => array('logo_url' => "http://
mmbiz.qpic.cn/mmbiz/K4LBh6RUO0qAa2sbY1EyJGDZ0eCetML4quMDRsiczNX9
8UPE6ryGM7ynjWCX1kibM5iaOLV5ibXHRhs8kdNoAthSjw/0",
4 'code_type' => "CODE_TYPE_BARCODE",
5 'brand_name' => "方倍票务公司",
6 'title' => "方倍会议门票",
7 'color' => "Color020",
8 'notice' => "使用时向检票员出示此券",
9 'description' => "请务必准时入场",
10 'sku' => array('quantity' => 10000),
11 'date_info' => array('type' => 1,
12 'begin_timestamp' => time,
13 'end_timestamp' => time + 2 * 86400),
14
15 ),
16 'meeting_detail' => "地点：水立方",
17 'map_url' => "http:// www.baidu.com/"
18 ),
19 );
20 $result = $weixin->create_card($data);
生成卡券ID以后，使用该ID生成二维码进行投放，其代码如下。
1 // 创建二维码进行投放
2 $data = array('action_name' => "QR_CARD",
3 // 'expire_seconds' => 1800,
4 'action_info' => array('card' => array('card_id' => "piPuduNg0bM6
Q5hB8rrcK3OXavSE",
5 // 'code' => "198374613512",
6 // 'openid' => "oFS7Fjl0WsZ9AMZqrI80nbIq8xrA",
7 'is_unique_code' => false,
8 'outer_id' => 100),
9
10 ),
11 );
12 $result = $weixin->create_card_qrcode($data);
当用户领取门票以后，为其更新座次信息，代码如下。
1 // 更新会议门票
2 $data = array(
3 'code' => "019538767119",
4 'card_id' => "piPuduNg0bM6Q5hB8rrcK3OXavSE",
5 'zone' => "C区",
6 'entrance' => "东北门",
7 'seat_number' => "2排15号",
8 );
9 $result = $weixin->update_card_meetingticket($data);
最终用户领取到的门票及更新后的门票信息如图16-11所示。
