PDO SELECT JOIN QUERY

Question

I tested the code below it works fine on phpmyadmin

SELECT registered_user_tbl.username, follow.follower_id FROM registered_user_tbl
  INNER JOIN follow
  ON follow.follower_id= 5 and registered_user_tbl.user_id= 5

I now want to implement the array version on my pdo project but it is not working kindly check and review query below

$this->db->select("SELECT registered_user_tbl.username, follow.follower_id FROM registered_user_tbl
    INNER JOIN follow
    ON follow.follower_id= :fid and registered_user_tbl.user_id= :fid",
    (":fid" =>$user));

Answer 1

The 2nd parameter to your select() method should probably be an array so the round brackets are incorrect, for your data parameters.

And you cannot reuse :fid twice in the parameter substitution.

So try this

$this->db->select(
        "SELECT registered_user_tbl.username, follow.follower_id 
        FROM registered_user_tbl
            INNER JOIN follow ON follow.follower_id= :fid1 
                and registered_user_tbl.user_id= :fid2",
        [":fid1" =>$user, ":fid2" =>$user]
        );
