編輯“HDWiki/許愿墻插件開發(fā)實例”（章節(jié)）

==詳細(xì)解釋==
1、admin_wish.php :這個是后臺點擊插件的【管理】需要調(diào)用的，在許愿墻插件中用不到，所以可以不用修改。
<pre>
<?php

!defined('IN_HDwiki') && exit('Access Denied');

class control extends base{

        function control(& $get,& $post){
                $this->base( & $get,& $post);
                $this->load('plugin');
                $this->loadplugin('wish');
                $this->view->setlang('zh','back');
        }

/*在后臺點擊管理觸發(fā)的方法，因為許愿墻用不到后臺，所以這里是默認(rèn)的echo語句 */
        function dodefault() {
                echo 'nothing!';  
        }

}

?>
</pre>

2、wish.php ：前臺訪問許愿墻插件需要用到的control，要編寫代碼，我們需要改寫下：
<pre>
<?php

!defined('IN_HDwiki') && exit('Access Denied');

class control extends base{

        function control(& $get,& $post){
                $this->base( & $get,& $post);
                $this->loadplugin('wish');
        }

/*顯示所有的許愿*/
        function dodefault(){
                $wishlist=$_ENV['wish']->get_list();
                $this->view->assign('wishlist',$wishlist);
                $this->view->display('file://plugins/wish/view/allwish');
        }
        
/*ajax提交許愿*/
        function dopost(){
                $receiver=empty($this->post['receiver'])?'自己'this->post['receiver'];
                $author=empty($this->post['author'])?'匿名'this->post['author'];
                $wish=$this->post['wish'];
                $_ENV['wish']->add_wish($receiver,$author,$wish);
                $this->message('1','',2);
        }

/*點擊我來貼一張顯示提交頁面*/
        function dowill(){
                $this->view->display('file://plugins/wish/view/postwish');
        }
        
}

?>
</pre>
3、wish.class.php ：許愿墻插件用到的model，要編寫代碼，我們需要改寫下：
<pre>
<?php

!defined('IN_HDwiki') && exit('Access Denied');

class wishmodel {

        var $db;
        var $base;

        function wishmodel(&$base) {
                $this->base = $base;
                $this->db = $base->db;
        }
        
/*這里是每個插件都需要編寫的方法，安裝插件的時候會自動調(diào)用此方法*/
        function install(){
                $sqls="CREATE TABLE wiki_wish (
                                `id` mediumint(8) unsigned NOT NULL auto_increment,
                                `wish` varchar(200) NOT NULL default '',
                                `receiver` varchar(15) NOT NULL default '',
                                `author` varchar(15) NOT NULL default '',

                $this->db->query($sqls); //創(chuàng)建許愿的數(shù)據(jù)表
                $plugin=array(
                        'name'=>'許愿墻',
                        'identifier'=>'wish',
                        'description'=>'每個人都有很多美好的愿望，許愿墻，一個你可以隨意許愿的地方，

                        'modules'=>''
                );
                $plugin['vars']=array();
                $plugin['hooks']=array();
                return $plugin;
        }


/*這里是每個插件都需要編寫的方法，卸載插件的時候會自動調(diào)用此方法*/
        function uninstall(){
                $this->db->query("DROP TABLE IF EXISTS wiki_wish");
        }
        
        
/*自己編寫的方法，插入一個許愿到數(shù)據(jù)庫表中*/
        function add_wish($receiver,$author,$wish){
                $style=rand(1,8);
                $this->db->query("INSERT INTO  ".DB_TABLEPRE."wish 
(receiver,author,wish,style,time) 
VALUES ('$receiver','$author','$wish',$style,'".$this->base->time."') ");
        }
        
/*自己編寫的方法，從數(shù)據(jù)庫讀取許愿數(shù)據(jù)*/
        function get_list($start=0,$limit=100){
                $wishlist=array();
                $query=$this->db->query
("SELECT *  FROM ".DB_TABLEPRE."wish ORDER BY time DESC limit $start,$limit ");
                while($wish=$this->db->fetch_array($query)){
                        $wish['time']=$this->base->date($wish['time']);
                        $wish['left']=rand(1,1024);
                        $wish['top']=rand(1,800);
                        $wishlist[]=$wish;
                }
                return $wishlist;
        }

}

4、allwish.htm：顯示所有許愿用到的view，也就是許愿墻的顯示頁面，要編寫代碼，最終代碼如下：

第八步：編寫完代碼并測試通過后發(fā)布到到插件共享平臺。首先進(jìn)入后臺管理中心，查看【已安裝插件】。如下圖，可以看到許愿墻插件：

[[Image:HDwish 6.jpg]]

然后點擊【分享】，如下圖，填寫完所有的信息，然后【確定】即可完成分享。

[[Image:HDwish 7.jpg|800px]]

分享后的插件在HDwiki開源官方站上有展示，默認(rèn)的是顯示為【未審核】，審核通過后，所有的HDwiki管理員都可以在后臺【全部推薦插件】看到你分享的插件。
