Question

I have two tables for storing information about a user. One is for authentication, the other is information the user will enter themselves. I am writing a model that will be used when the user interacts with this information. The following method is to return data for display and modification.

I need a query that will return ’email’ and ‘username’ from $accounts_table and * from $profiles_table. I can’t seem to get my head around the JOIN syntax though. I understand how joins work, but my queries throw sentax errors.

function get_userdata($id){
     $data = array();

     $this->db->get_where($this->profiles_table, array('user_id' => $id));
     $this->db->join($this->accounts_table.'.email', $this->accounts_table.'.id = '.$this->profiles_table.'.user_id');
     $data= $this->db->get();

     return $data;
}

I see a couple of issues:

You should be using $this->db->where(), instead of $this->db->get_where(). get_where() executes the query immediately.

$this->db->get_where('user_id', $id);

Also the first argument of $this->db->join() should only be the table name, excluding the field.

$this->db->join($this->accounts_table, $this->accounts_table.'.id = '.$this->profiles_table.'.user_id');

And you’re returning $data which is just an empty array(). You would need to pass the query results to $data like this:

$data = $record->result_array();
