Question

This is my query:

$query = $this->db->query('     SELECT archives.id, archives.signature, type_of_source.description, media_type.description, origin.description      FROM archives, type_of_source, media_type, origin                                                                  WHERE archives.type_of_source_id = type_of_source.id                                                               AND type_of_source.media_type_id = media_type.id                                                                   AND archives.origin_id = origin.id                                                                                 ORDER BY archives.id ASC '); 

But how to output the result? This works, but only gets the last description (origin.description):

foreach ($query->result_array() as $row) {     echo $row['description']; } 

This doesn’t work:

foreach ($query->result_array() as $row) {     echo $row['type_of_source.description']; } 

Or should I rename the columns (e.g. type_of_source_description)?

Answer 1

This actually has very little to do with CodeIgniter and a lot with how mysql_fetch_assoc provides the query results.

The solution is that you should rename the columns inside the query using "AS", e.g.

select type_of_source.description as type_of_source_description, origin.descripotion as origin_descripotion from ....
