我有两个表：登录and跟随`。
表名：
login
字段：id,email,username,imageurl表名：
follow
字段：id:user_id:follow_id
这就像 Twitter 追随者的概念。我想获取姓名的详细信息myfollower以及myfollower以下人员的姓名。
为此，我编写了如下代码。
public function follw ()
{
if( $this->input->get("userid") )
{
extract($this->input->get());
$followers_list = array();
$follower = array();
$query = $this->db->query('select follow_id from follow where user_id = '.$userid.'')->result();
foreach($query as $row)
{
$follower['follower_id'] = $row->follow_id;
if($follower['follower_id'] == "")
{
echo "hi";
}
else
{
$query3 = $this->db->query('select username from login where id = '.$follower['follower_id'].'')->result();
foreach($query3 as $row3)
{
$follower['followuser'] = $row3->username;
}
$query1 = $this->db->query('select follow_id from follow where user_id = '.$follower['follower_id'].'')->result();
foreach($query1 as $row1)
{
$follower['follow_id'] = $row1->follow_id;
if($follower['follow_id'] == "")
{
echo "jeeva";
}
else
{
$query2 = $this->db->query('select username from login where id = '.$follower['follow_id'].'')->result();
foreach($query2 as $row2)
{
$follower['username'] = $row2->username;
}
}//second for each in else loop
}//first foreach in else loop
}//main else
$followers_list[] = $follower;
}
$str = json_encode($followers_list);
echo stripslashes($str);
}
else
{
echo '[{"status":"Failure - Error Occured - Not Enough Details provided"}]';
}
}
我得到这样的输出：
[{"follower_id":"12","followuser":"janmejoy","follow_id":"24","username":"sarvana"},{"follower_id":"10","followuser":"jeeva","follow_id":"23","username":"selva"},{"follower_id":"6","followuser":"raj","follow_id":"17","username":"jeeva"},{"follower_id":"23","followuser":"selva","follow_id":"22","username":"guru"}]
此输出显示myfollower' 姓名 和myfollower' 关注人员姓名，但问题是它仅显示myfollower' 关注人员姓名的一个成员。
但是，我想要这样的输出：
[{"follower_id":"12","followuser":"janmejoy",{"follow_id":"24","username":"sarvana",follow_id":"13","username":"jai",follow_id":"9","username":"raj"}},{"follower_id":"10","followuser":"jeeva","follow_id":"23","username":"selva"},{"follower_id":"6","followuser":"raj","follow_id":"17","username":"jeeva"},{"follower_id":"23","followuser":"selva","follow_id":"22","username":"guru"}]
