I wanted to be able to change the object name of a Model that was being loaded in an array. Specifically, I was autoloading multiple models. When loading models in an array I couldn't change the name of the object that the model was loaded as, so I extended the Loader class library. Hope this helps someone.
Usage:
Code:
$this->load->model(array('model1'=>'model1_name', 'model2'));
The only changes that needed to be made were:
Code:
if (is_array($model))
{
foreach($model as $babe=>$name)
{
// Does the babe have a name? If not just call her babe.
if($babe == '') {
$babe = $name;
}
$this->model($babe, $name);
}
return;
}
To implement, create a file called MY_Loader.php in /system/application/libraries.
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Loader extends CI_loader {
function model($model, $name = '', $db_conn = FALSE)
{
if (is_array($model))
{
foreach($model as $babe=>$name)
{
// Does the babe have a name? If not just call her babe.
if($babe == '') {
$babe = $name;
}
$this->model($babe, $name);
}
return;
}
if ($model == '')
{
return;
}
// Is the model in a sub-folder? If so, parse out the filename and path.
if (strpos($model, '/') === FALSE)
{
$path = '';
}
else
{
$x = explode('/', $model);
$model = end($x);
unset($x[count($x)-1]);
$path = implode('/', $x).'/';
}
if ($name == '')
{
$name = $model;
}
if (in_array($name, $this->_ci_models, TRUE))
{
return;
}
$CI =& get_instance();
if (isset($CI->$name))
{
show_error('The model name you are loading is the name of a resource that is already being used: '.$name);
}
$model = strtolower($model);
if ( ! file_exists(APPPATH.'models/'.$path.$model.EXT))
{
show_error('Unable to locate the model you have specified: '.$model);
}
if ($db_conn !== FALSE AND ! class_exists('CI_DB'))
{
if ($db_conn === TRUE)
$db_conn = '';
$CI->load->database($db_conn, FALSE, TRUE);
}
if ( ! class_exists('Model'))
{
load_class('Model', FALSE);
}
require_once(APPPATH.'models/'.$path.$model.EXT);
$model = ucfirst($model);
$CI->$name = new $model();
$CI->$name->_assign_libraries();
$this->_ci_models[] = $name;
}
}
?>
