CI框架微信开发-自定义菜单，ci框架自定义菜单

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
	pid	int(11) NULL
	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

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 = "var_export
