问题
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?
回答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
回答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.
