HTML:

   {OVOV:$answer_datas.goods/}       {OVOV:$answer_datas.bads/}   



HTML对应的php文件


$value){			if($value['uid']==$uid){		 		$zan_lists[]=$value['answer_id'];			}		} 		$smarty->assign('zan_list',$zan_lists);//查询当前登录的会员的uid对应的点赞的回答 		/*****赞结束****/ 		/*****踩开始****/		$cai_list = json_decode(str_replace("'",'"',$cai_json),true);		$cai_lists=array();		foreach($cai_list as $key=>$value){			if($value['uid']==$uid){		 		$cai_lists[]=$value['answer_id'];			}		} 		$smarty->assign('cai_list',$cai_lists);//查询当前登录的会员的uid对应的踩的回答 		/*****踩结束****/		$smarty->display('自己的静态页面');		exit();	break;}?>


ajax文件:

参数错误!';exit();}switch($action){	 case 'zan'://点赞(给力)		//$zan_json是数组文件中设置的数组变量,存的是json数据----1		$zan_array = json_decode(str_replace("'",'"',$zan_json),true);				//获取当前的会员的uid-----2		$user_answer['uid']=$uid;		//获取对应的赞的回答的id----2		$user_answer['answer_id']=$_POST['answer_id'];				//将会员的uid和答案的id一块的数组放到指定的数组中----3		$zan_array[]=$user_answer;				$config_path = 'shuzu/ovovsys_zan.php';		if(!file_exists($config_path)){			$Base->ErrorMsg('文件错误:shuzu/ovovsys_zan.php 不存在!');exit();		}				//将指定的数组转换成json数据,并且将双引号转换成单引号,不然放到数组文件中后会出错----4		$zan_new_json = str_replace('"',"'",json_encode($zan_array));				$fp = @fopen($config_path,'r+');		if(!$content = @fread($fp,filesize($config_path))){			$Base->ErrorMsg('无法读取shuzu/ovovsys_zan.php文件!');exit();		}				//执行替换,将数组文件中对应的json数据----5		$content = str_replace("\$zan_json = \"{$zan_json}\"","\$zan_json = \"{$zan_new_json}\"",$content);		$fp = @fopen($config_path,'w+'); 		@fwrite($fp,$content); 				//修改对应的数据表中的数据----5		$Db->ThisQuery("update `".$db_prefix."ask_answers` set `goods`=`goods`+1 where `ans_id`=".$user_answer['answer_id']."");		exit();	break;	 case 'cai'://踩(不给力)		$cai_array = json_decode(str_replace("'",'"',$cai_json),true);		$user_answer['uid']=$uid;		$user_answer['answer_id']=$_POST['answer_id'];		$cai_array[]=$user_answer;		$config_path = 'shuzu/ovovsys_zan.php';		if(!file_exists($config_path)){			$Base->ErrorMsg('文件错误:shuzu/ovovsys_zan.php 不存在!');exit();		}		$cai_new_json = str_replace('"',"'",json_encode($cai_array));		$fp = @fopen($config_path,'r+');		if(!$content = @fread($fp,filesize($config_path))){			$Base->ErrorMsg('无法读取shuzu/ovovsys_zan.php文件!');exit();		}		$content = str_replace("\$cai_json = \"{$cai_json}\"","\$cai_json = \"{$cai_new_json}\"",$content);		$fp = @fopen($config_path,'w+'); 		@fwrite($fp,$content); 		$Db->ThisQuery("update `".$db_prefix."ask_answers` set `bads`=`bads`-1 where `ans_id`=".$user_answer['answer_id']."");		exit();	break;}?>


对应的数据文件(因为创建数据库时没有创建踩和赞的再断,所以这里就用php文件存变量的方式保存了一下答案对应的赞和踩的数据,其中包含用户的id和答案的id)

你没看错,就是两个变量
