As mwhitney said, extending the db of CI isn't the way to go here.
You could add a model (MY_Model) to your core folder and extends CI_Model. To get access to every model, run parent::__construct(); in the constructor of MY_Model. Then simply overwrite insert in MY_Model, like this:
PHP Code:
<?php
class MY_Model extends CI_Model {
public function __construct()
{
parent::__construct();
}
public function insert($table = '', $set = NULL, $escape = NULL, $update_on_duplicate = FALSE)
{
if(!update_on_duplicate)
return parent::insert($table, $set, $escape);
//your code
}
}
This is also a nice way to get ride of typing the table everytime, because you could add a protected field $table to the class and the method use it via $this->table.
In another model, which extends MY_Model., you then can overwrite $table, so that for example a user model, which uses a user table, automatically uses $table instead of typing the user table every time.
PHP Code:
<?php
class MY_Model extends CI_Model {
protected $table = '';
public function __construct()
{
parent::__construct();
}
public function insert($set = NULL, $escape = NULL, $update_on_duplicate = FALSE)
{
if(!update_on_duplicate)
return parent::insert($this->table, $set, $escape);
//your code
}
}
But this is optional.
