Question

您好我正在尝试从管理员处获取未读回复的数量。那些是支持票。有三个表如下。

table: supportticket

id | date | username | email | status | subject | message | adminreply | 
admindate | read


table: ticketreplies

id | tid | userid | name | email | date_added | message | admins


table: tickets 

id | userid | trackid | name | email | date_added | title | message | 
status | urgency | lastreply


table: ticket_read 

id | idt | lu

我试过了：

$query = "SELECT COUNT(*) FROM first table WHERE to_user_id
=".$_SESSION['user_id']." AND `read` = 0";

但没有成功。希望有更多的想法。我是新人。

*when ticket is created by user this table gets update:


tickets

id   |    userid   |   trackid   |    name   |    email     |    date_added     
|    title    |    message   |    status    |    urgency    |    lastreply
456        2           123-456       user     user@user.com    3/23/2017 
15:52      test           test           open            medium        
3/24/2017 15:52



* when admin replies

ticketreplies:

id   |   tid   |    userid   |   name    |   email   |       date_added         
|      message       |   admins    0         456         0                                   
3/23/2017  15:52          replied to test         1

ticket_read

id   |   idt   |  lu
0        456       1

P.S。当管理员回复票证表获取状态已回答并且最后获得新的日期时间

Answer 1

我确信它不是to_user_id而id first_table所以这样改变

$query = "SELECT COUNT(*) FROM `first_table` WHERE `id`
='".$_SESSION['user_id']."' AND `read` = 0";

假设您没有提供确切的表格名称，为什么first table不是first_name

Answer 2

试试这个

  $query = "SELECT COUNT(*) FROM first table 
  WHERE first_table.id =".$_SESSION['user_id']." AND `read` = 0";

Answer 3

由于没有太大的信息是在问题（表之间没有逻辑连接在问题提供）给定的，则在壳体id是票的参考号码可以尝试这一点。

$query = "SELECT COUNT(*) FROM supportticket 
INNER JOIN tickets 
ON supportticket.id=tickets.id
WHERE tickets.userid =".$_SESSION['user_id']." AND supportticket.read = 0";

或者

$query = "SELECT COUNT(*) FROM supportticket 
INNER JOIN ticketreplies 
ON supportticket.id=ticketreplies.id
WHERE ticketreplies.userid =".$_SESSION['user_id']." AND supportticket.read = 0";

Answer 4

根据我对您的问题和表格结构的理解，您应该使用$this->field['class']。并对表格进行一些更改。

示例：

function asyncTask1(done) {
  setTimeout(() => {
    console.log('task 1 done');
    done(1);
  }, 500);
}
function asyncTask2(done) {
  setTimeout(() => {
    console.log('task 2 done');
    done(2);
  }, 400);
}
function asyncTask3(done) {
  setTimeout(() => {
    console.log('task 3 done');
    done(3);
  }, 300);
}

function sequential(tasks = []) {

}
 sequential(tasks);

first_table应该包含 trackid ，就像你的second_table一样。此票证ID将是您获取特定用户的所有未读回复的关键。

但这将根据您存储邮件的方式和回复表格而改变。

使用COUNT函数计算新回复
