oops...
Quote:Note: The Database classes can not be extended or replaced with your own classes, nor can the Loader class in PHP 4. All other classes are able to be replaced/extended.
so how can i use database in my own libraries?
edit: think i got it!
i have to use model in order to interact with database inside custom library...

Not necessarily, this should work aswell:
Code:
$this->ci->load->library('database');
$this->ci->db->get('table_name');CI total newbie topic - El Forum - 08-28-2010

how to get the called class if the model is allready extended...
Code:
<?php
class Main_model extends Model {
function __construct() {
parent::Model();
echo get_class($this);
}
}
class Final extends Main_model {
}i need to get the name of the last class 'Final' for some db methods like create, update, delete etc. don't want to write them each time.
in order that to work, i have to autoload main_model but this main model is actually abstract and i call methods from Final

and a question about form_validation. in my login form if the username and/or the password are not validating, then is it possible to display error message like the form_validation works with rules...
RESOLVED

[eluser]keevitaja[/eluser]
if the form doesn't validate, i can only call a function where form was sent in order to get the error messages. i would like to redirect the page...
Code:
function index() {
//output form
}
function send_data {
redirect(index);
}in that case i don not get the errors... is it possible to fix it? i like to let people refresh the page without sending the form data again!

can controllers be stored in a subfolder and then call like http://mysite.com/subfolder/controller ?
CI total newbie topic - El Forum - 08-30-2010
[eluser]WanWizard[/eluser]
Yes.
With the restriction that you can't have a folder and a controller with the same name. So if you have:
test1.php
test1/test2.php
then you can never load the test2 controller, as CI looks for a matching controller first, and only for a folder if the controller isn't found.

this is strange. i tested to put controllers in separate folder and it didn't work. now it works... probably made mistake first time
