Codeigniter 显示表 2 中每条 id 与表 1 相似的记录的记录

Question

I've been bugged by this problem in CodeIgniter. I want to display all records in table 2 for each record in table 1. like this illustration:

id | name |             id | pets |
1  | john doe |          1 | dogs |
2  | jane doe |          1 | cats |
                         2 | hamsters |
                         2 | birds |
                         2 | iguanas |

and display like this in views:

id: 1
name: John doe
pets: dogs, cats

id: 2
name: jane doe
pets: hamsters, birds, iguanas

this is an analogy. any way to do it?

Answer 1

Since your problem is not clear because you are not given any code. I have give only idea to join the tables. You can write query like this in codeigniter.

$data = $this->db->query("SELECT a1.id,al.name,a2.pets FROM TableA a1
INNER JOIN TableB a2 
ON a1.id = a2.id WHERE a1.id=1")->result(); // here you got objects

print_r($data); //This will show the result

If you give your code then we will surely solve your problem.
