How can I access a CodeIgniter configuration varia

Question

I would like to access the $db['default']['dbprefix'] variable from /application/config/database.php (CodeIgniter configuration file) from within a model so I can write my own queries using the value from the file.

How can this be done?

Answer 1

Try:

$this->load->database();
echo $this->db->dbprefix;

Normally you can use $this->config->item but I think that only allows variables set in $config

Answer 2

The documentation says you should be using:

$this->db->dbprefix('tablename');

Doesn't make a huge amount of difference but could be an easier syntax.
