内容图文
在CI框架下面实现了自定义菜单功能.写了一个model,一个类库.顺便附带access_token的实现方式
<?php class Makemenu{ public $menustr; public function __construct(){ } public function init(){ $this->dolist(); return $this->setmenu(); } private function dolist(){ $CI =& get_instance(); $CI -> load ->model("Menu_model","menu"); $plist = $CI->menu ->isplist(); foreach($plist as $pid){ $pidarr[] = $pid['pid']; } $list = $CI->menu ->maketree($CI->menu->getlist()); foreach($list as $btn){ if(in_array($btn['id'],$pidarr)){ //生成不带key和url的链接作为父级菜单 $btn_arr[$btn['id']] = array("type"=>$btn['menutype'], "name"=>$btn['content']); }elseif($btn['pid'] == 0){ //生成有操作的一级菜单 $btn_arr[$btn['id']] = array("type"=>$btn['menutype'], "name"=>$btn['content'], "key"=>$btn['clickkey'], "url"=>$btn['url']); }else{ //生成子菜单 $btn_arr[$btn['pid']]['sub_button'][] = array("type"=>$btn['menutype'], "name"=>$btn['content'], "key"=>$btn['clickkey'], "url"=>$btn['url']); } } $btnarr['button'] = array_values($btn_arr); $r = $this->menustr = json_encode($btnarr,JSON_UNESCAPED_UNICODE); return $r; } private function setmenu(){ $accesstoken = get_access_token(); $url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token={$accesstoken}"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)'); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_AUTOREFERER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $this->menustr); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $info = curl_exec($ch); if (curl_errno($ch)) { return curl_error($ch); } curl_close($ch); return $info; } }
上面是library里面的内容,主要是根据数据表生成菜单的json串
<?php class Menu_model extends CI_Model { public $table_name; public function __construct(){ parent::__construct(); $this->load->database(); $this->table_name = "data_menu"; } public function query($sql){ return $this->db->query($sql); } public function getone($id){ $get_sql = "select * from {$this->table_name} where id = {$id}"; return $this->query($get_sql)->row(); } public function addone($data){ if(($data['pid'] == 0)&&($this->checksum()>=3)){ //一级菜单不超过3个 return "toomany1"; }elseif(($data['pid']!=0)&&($this->checksum($data['pid']))>=7){ //二级菜单不超过7个 return "toomany2"; } if(is_array($data)&&!empty($data)){ $keys = "`".implode("`,`",array_keys($data))."`"; $vals = "'".implode("','",array_values($data))."'"; $insert_sql = "insert into {$this->table_name} ($keys) values ($vals)"; return $this->query($insert_sql); }else{ return false; } } public function del($id){ $infos = $this->getone($id); $del_sql = "delete from {$this->table_name} where id = {$id} and pid = {$id}"; return $this->query($del_sql); } private function checksum($id = ''){ if($id == ''){ $get_sql = "select count(1) as total from {$this->table_name} where pid =0"; }else{ $id = intval($id); $get_sql = "select count(1) as total from {$this->table_name} where pid ={$id}"; } $r = $this->db->query($get_sql)->row(); return $r->total; } public function getplist(){ //获取一级菜单 $get_sql = "select * from {$this->table_name} where pid=0 order by menuorder asc"; return $this->db->query($get_sql)->result_array(); } public function isplist(){ $get_sql = "select pid from {$this->table_name} where pid <> 0 group by pid"; return $this->db->query($get_sql)->result_array(); } public function getlist(){ $get_sql = "select * from {$this->table_name} where 1 order by pid asc, menuorder asc"; return $this->db->query($get_sql)->result_array(); } public function maketree($data){ $pids = array(); foreach($data as $k=>$v){ if($v['pid'] == 0){ $pids[$v['id']][] = $v; }else{ $pids[$v['pid']][] = $v; } } list($t1,$t2,$t3) = array_values($pids); $r = array_merge_recursive(is_array($t1)?$t1:array(),is_array($t2)?$t2:array(),is_array($t3)?$t3:array()); return $r; } public function update($data){ if(is_array($data)&&!empty($data)){ $id = $data['id']; unset($data['id']); foreach($data as $k=>$v){ $update_arr[] = "`".$k."` = '".$v."'"; } $update_fs = implode(",",$update_arr); $update_sql = "update {$this->table_name} set {$update_fs} where id = {$id}"; return $this->query($update_sql); }else{ return false; } } }
上面是model里面的各种方法.
数据库的表结构如下,附创建表的语句.
CREATE TABLE `menu` ( `id` int(11) NOT NULL AUTO_INCREMENT, `content` varchar(20) DEFAULT NULL, `pid` int(11) DEFAULT '0', `menutype` enum('click','view','scancode_push','scancode_waitmsg','pic_sysphoto','pic_photo_or_album','pic_weixin','location_select') DEFAULT 'view' COMMENT '消息类型', `url` varchar(200) DEFAULT NULL COMMENT '链接地址', `clickkey` varchar(20) DEFAULT NULL COMMENT '事件KEY', `menuorder` int(11) DEFAULT NULL COMMENT '排序', `submenu` tinyint(2) DEFAULT '0', PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8
| Field | Type | Comment | |
| 主键 | id | int(11) NOT NULL | |
| content | varchar(20) NULL | <内容> | |
| pid | int(11) NULL | <父类ID> | |
| menutype | enum('click','view','scancode_push','scancode_waitmsg','pic_sysphoto','pic_photo_or_album','pic_weixin','location_select') NULL | 消息类型 | |
| url | varchar(200) NULL | 链接地址 | |
| clickkey | varchar(20) NULL | 事件KEY | |
| menuorder | int(11) NULL | 排序 | |
| submenu | tinyint(2) NULL | <是否是子菜单> |
下面是写在system/core/common.php下面的获取token的方法,其实要做一个加盐处理,要么会有恶心的人做恶心的事情.
function get_access_token(){ //从微信服务器获取access_token 并保留一个小时 $old_filename = APPPATH."cache/".md5(date("YmdH",time()-3600)).".php"; @unlink($old_filename); $filename = APPPATH."cache/".md5(date("YmdH",time())).".php"; if(is_file($filename)){ $r = include($filename); }else{ $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".APPID."&secret=".APPSECRET; $access_token = file_get_contents($url); $res = "<?php return ".var_export(json_decode($access_token,1),1).";"; file_put_contents($filename,$res); $r = include($filename); } return ($r['access_token']); }
前面的菜单管理就不写了,就是管理那个表的数据,保证数据表里面的数据没问题即可.
在控制器里面只需要
$this->load->library("Makemenu");
然后调用 $this->makemenu->dolist();
就会推送到微信的服务器. 还需要注意在入口文件定义两个常量 APPID和APPSECRET .
放出来给大家,希望有用,也给我自己备份个.
