很久没有更新百科系统程序了，应该有几个月了，今天就接着之前的更新内容，继续发布，本章节是单语言/多语言仿百度HDwiki百科网站源码开发 第五篇。

程序源码：不加密，开源

程序开源：PHP+MySQL+thinkPHP框架

程序演示：http://baike.yetukeji.cn, 账户18127950266 ，密码qq2360248666

先上几张效果图先

这个是手机版

这部分是代码区

<?php
namespace app\index\controller;
use app\Base;
use think\App;
use think\facade\Cache;
use think\Request;
use think\facade\View;
use think\facade\Db;
class Common extends Base
{
    public function __construct()
    {
        parent::__construct();
        $this->loading_language();
        $this->personal_nav();
    }

    //设置默认语言
    function loading_language(){
        if(cookie('lang') == null){
            cookie('lang',config('lang')['default_lang']);
            //echo "<script language=JavaScript> location.replace(location.href);</script>";
        }
    }

    function personal_nav($id=0){
        $personal_nav = [
            [
                'id' => '10001',
                'name' => '个人中心',
                'lang_key' => 'nav_personal_center',
                'url' => '/buyer/index',
                'status' => 1
            ],
            [
                'id' => '10002',
                'name' => '我的收藏',
                'lang_key' => 'nav_my_collection',
                'url' => '/buyer/collection',
                'status' => 1
            ],
            [
                'id' => '10003',
                'name' => '个人资料',
                'lang_key' => 'nav_personal_data',
                'url' => '/buyer/data',
                'status' => 1
            ]
        ];
        if($id != 0){
            foreach ($personal_nav as $item) {
                if($item['id'] == $id){
                    return $item;
                }
            }
        }
        View::assign('personal_nav',$personal_nav);
        return [
            'id' => '10000',
            'name' => '页面不存在',
            'lang_key' => '',
            'url' => '/buyer/error',
            'status' => 1
        ];
    }​

语言包切换

public function langSwitch(){
        $lang = input('lang');
        if($lang != ''){
            if($this->is_language($lang)){
                cookie('lang',$lang);
                //cookie('think_lang',$lang);
                return $this->success('设置成功');
            }
        }
        return $this->error('设置失败');
    }

判断是否存在语言

function is_language($lang=0){
        $language_list = config('console')['lang'];
        foreach($language_list as $key => $value){
            if($key == $lang){
                return true;
            }
        }
        return false;
    }

验证邮箱

function is_email($email){
        $chars = "/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/";
        if (preg_match($chars, $email)){
            return true;
        }else{
            return false;
        }
    }

    public function info($url=''){
        $top_info_id = get_info_id($url);
        if(input('cid/d') == ''){
            $info = get_nav_info($top_info_id);
        }else{
            $info = get_nav_info(input('cid/d'));
        }
        return $info;
    }

    public function topInfo($url=''){
        $top_info_id = get_info_id($url);
        return get_nav_info($top_info_id);
    }

    public function assign($info,$top_info=''){
        if($top_info == ''){
            $top_info = [
                'id' => -1,
                'name' => '',
                'url' => ''
            ];
        }
        if(empty($info['name'])){
            $info['name'] = '';
        }
        if(empty($info['keywords'])){
            $info['keywords'] = '';
        }
        if(empty($info['description'])){
            $info['description'] = '';
        }
        if(empty($info['lang_key'])){
            $info['lang_key'] = '';
        }
        View::assign('seo_keywords',$info['keywords']);
        //View::assign('seo_title',$info['name'].'-'.setting('web_name'));
        View::assign('seo_title',l($info['lang_key']).' - '.l('web_name'));
        View::assign('seo_description',$info['description']);
        View::assign('top_info',$top_info);
        View::assign('info',$info);
    }

    public function success($msg = '', $data = ''){
        return json(['code' => 1, 'msg' => $msg, 'data' => $data]);
    }

    public function error($msg = '', $data = ''){
        return json(['code' => 0, 'msg' => $msg, 'data' => $data]);
    }
