Creating variables of type (class)

2012-05-25T04:30:15Z

Hi, Ultra newb question,

I want to create a custom class that will be used in models, views and controllers. I will be creating instances of this class in many non member functions. Where do I define this class to be available everywhere?

Note: I am less interested in methods, however, I am dealing with complex data and need to use lots of properties. I want to create instances of this class in many non member functions.

Thanks for the help.

PROCEDURE#4

Please tell me if this installation procedure is right:

1-I uploaded the dir CodeIgniter_2.1.0 to root/home moving index.php to root level

/*
|—————————————————————————————————————
| Index File
|—————————————————————————————————————
|
| Typically this will be your index.php file, unless you’ve renamed it to
| something else. If you are using mod_rewrite to remove the page set this
| variable so that it is blank.
|
*/
$config[‘index_page’] = ‘/root/index.php’;

/*
|—————————————————————————————————————

3- I edited index,php moving it to root level this way:

*———————————————————————————————-
* APPLICATION ENVIRONMENT
*———————————————————————————————-
*
* You can load different configurations depending on your
* current environment. Setting the environment also influences
* things like logging and error reporting.
*
* This can be set to anything, but default usage is:
*
* development
* testing
* production
*
* NOTE: If you change these, also change the error_reporting() code below
*
*/
define(‘PRODUCTION’, ‘development’);
/*
*———————————————————————————————-
* ERROR REPORTING
*———————————————————————————————-
*
* Different environments will require different levels of error reporting.
* By default development will show errors but testing and live will hide them.
*/

if (defined(‘PRODUCTION’))
{
switch (ENVIRONMENT)
{
case ‘development’:
error_reporting(E_ALL);
break;

case ‘testing’:
case ‘production’:
error_reporting(0);
break;

default:
exit(‘The application environment is not set correctly.’);
}
}

*———————————————————————————————-
* SYSTEM FOLDER NAME
*———————————————————————————————-
*
* This variable must contain the name of your “system” folder.
* Include the path if the folder is not in the same directory
* as this file.
*
*/
$system_path = ‘/root/home/CodeIgniter_2.1.0/system’;

/*
*———————————————————————————————-
* APPLICATION FOLDER NAME
*———————————————————————————————-
*
* If you want this front controller to use a different “application”
* folder then the default one you can set its name here. The folder
* can also be renamed or relocated anywhere on your server. If
* you do, use a full server path. For more info please see the user guide:
* http://codeigniter.com/user_guide/general/managing_apps.html
*
* NO TRAILING SLASH!
*
*/
$application_folder = ‘/root/home/CodeIgniter_2.1.0/application’;

NOTES FROM OP
Maybe it should be just
$system_path = ‘system’;
and
$system_path = ‘system’;
since I never moved them from root/home

Altering database file is not meant on all cases or does it have to be added the database
of the script that is using code igniter?

ion_auth Groups issue

2012-05-25T02:45:32Z

Ok, I am trying to assign Multiple groups using the form_multiselect() function. Here is the code the pertains to the issue:

Setting the options in the controller

$this->data['options'] = array(
                  '1' => lang('create_admin_storeadm'),
                  '4' => lang('create_admin_reports'),
                  '3' => lang('create_admin_superadm')
                ); 

Echoing the form in the view:


echo form_multiselect('groups', $options); ?>

Processing the groups in the controller:


$groups = array($this->input->post('groups[]'));

If I select the options for group IDs 3 and 4, the database inputs groups 0 and 2…

I have a feeling its the second part in the controller… the art where I set groups tot he array. How do I get the selections from groups[] to be #, #?

Incorrect SQL Query Result with Active Record

2012-05-25T02:40:07Z

Can anyone tell me why running a query through phpMyAdmin on my database gives me a different result than my active record styles query?

The query through phpMyAdmin is


SELECT * FROM `planets` GROUP BY `player`

which returns approximately 46,200 results.

The active record query is


$this->db->from('planets')->group_by('player')->count_all_results();

and it returns approximately 6,600 results.
