CI框架微信开发-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	<ID>
	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.
