*寻找



-> :

第一个查询是这样的

 SELECT u.user_id as 'uid',r.date as 'date' 
 FROM users AS u 
 INNER JOIN  requirement r ON u.users_id=r.users_id 
 GROUP BY u.user_id

Join需要知道在需求表中注册的用户

输出：

Name，Date

2行，如示例所示

然后在里面

 SELECT label_name,label_value FROM requirement 
 WHERE user_id = '$data[uid]'

输出：

label\u name，label\u value

对于第一个用户-3行和第二个用户-2行

您可以使用并遵循此演示：

您应该使用mysql的

CONCATE（）

函数。

试试这个解决方案。虽然有点长，但它会解决你的问题

@krishna radadiya-我认为我的问题与你的答案不同。我可以理解你的问题，并给出来自任何其他表或一个表的Concate字符串的唯一解决方案，你可以使用Concate函数，所有字符串都是来自任何表的Concate。如果用户填写了2个要求（请参见要求id）。如果是那样的话，就好像是。在您的情况下，如果用户只填写了一个需求，那么您是对的，但是如果用户填写了多个需求，那么我希望这样-@Divakarcool，我已经编辑了我的解决方案。它应该根据你的评论工作。在这两种情况下，我们得到相同的结果。我做了更多的编辑。看一看说“谢谢你这么多朋友终于开始工作了”的部分请尝试将以下调试行立即放在

而{

：

var\u dump（$data）；

之后，然后发布结果。（这将有助于更好地理解这里的问题所在）。不要使用不推荐使用的

mysql.*
