Load and use Codeigniter model in non Codeigniter class - php

I was just wondering if there is a way to use codeigniter model in other non Codeigniter classes... Let me give you an example.
I have this MyTestClassTests class which extends PHPUNIT_Framework_testCase
<?php
require_once '../../vendor/autoload.php';
use Facebook\WebDriver\Remote\WebDriverCapabilityType;
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\WebDriverBy;
use Facebook\WebDriver\Interactions\WebDriverActions;
use Sunra\PhpSimple\HtmlDomParser;
class MyTestClassTests extends PHPUnit_Framework_TestCase
{
public function testDoSomething()
{
// Do some test
// get results
// Store results via Codeigniter Model, if possible?
$results = 'some results';
$this->load->model('results');
$this->results->import($results);
}
}
Now once test is finished i would like to store test results in to the database. Is there a way to call/initialize CodeIgniter model in current class to use it and store data? This file is located in the Codeigniters controllers folder.
If you need any additional information's please let me know and i will provide. Thank you!

Since you appear to be unit testing you should consider using ci_phpunit-test which makes it much easier to use PHPUnit with CodeIgniter 3.x.
Because you're unit testing the following may not apply. These examples only work within an fully instantiated CI framework. Within that context there are a couple ways to give a stand-alone class access to the CI object.
One approach is to capture the CI instance in a class property.
class MyTestClassTests extends PHPUnit_Framework_TestCase
{
protected $CI;
public function __construct()
{
// Assign the CodeIgniter super-object
$this->CI = & get_instance();
}
public function testDoSomething()
{
// Do some test
// get results
// Store results via Codeigniter Model, if possible?
$results = 'some results';
//use the class property to access CI classes and methods
$this->CI->load->model('results');
$this->CI->results->import($results);
}
}
A second approach uses the PHP magic method __get. The advantage is it's much easier to write the code. The disadvantage is it's a tiny bit less efficient because extra code is executed each time you access the CI instance.
class MyTestClassTests extends PHPUnit_Framework_TestCase
{
/**
* Enables the use of CI super-global without having to define an extra variable.
*
* #param $var The CI property or method to access
* #return mixed
*/
public function __get($var)
{
return get_instance()->$var;
}
public function testDoSomething()
{
// Do some test
// get results
// Store results via Codeigniter Model, if possible?
$results = 'some results';
//you get to write code as if you were part of the CI object.
//IOW, you write code normally
$this->load->model('results');
$this->results->import($results);
}
}

In order to use codeigniter model in your non codeigniter class you have to instantiate CI first.
In your case below code will work.
$CI = & get_instance()
$CI->load->model('results');
$CI->results->your_function();

Hide Restler method from swagger-ui

Using Restler 3.0.0-RC6, which internally packages swagger-ui, I have an API method defined like so:
<?php
namespace v1:
class PostgreSQL {
public function fetchArray($sql, $args = null) {
And then all of my classes that I include via Restler's addAPIClass extend that PostgreSQL class. That means when swagger runs, every single API shows a fetchArray function. I'd like to have that method not appear in the swagger documentation as it's not really part of the API. Other 'things' on the website also use the class though so I can't change the modifier from public.
What's the proper syntax to hide that method from swagger-ui's webpage?
There are two ways to achieve this,
One is to mark the fetchArray method as private with #access private comment. This will remove fetchArray from all api urls while keeping the fetchArray still accessible for PHP
Problem in your case is that you don't want to modify the PostgreSQL as its part of a framework that is maintained by composer. Instead of directly extending it from the base class use an intermediary class which adds the comment and then extend that class as shown below
class Base {
public function fetchArray(){
return array();
}
}
class Intermediary extends Base {
/**
* #access private
*/
public function fetchArray(){
return array();
}
}
class MyApi extends Intermediary { //instead of extends Base
//other api methods here
//see in the explorer to note that fetchArray is no longer listed
}
Another way is to just exclude it on Explorer with
use Luracast\Restler\Explorer;
Explorer::$excludedPaths = array('myapi/fetcharray','another/fetcharray');
You should not extend your API layer class from a data layer class. Just use the data layer class.
class DataLayer
{
public function fetchArray()
{
return array();
}
}
class ApiLayer
{
private $dl;
function __construct()
{
$this->dl = new DataLayer();
}
public function getAll()
{
return $this->dl->fetchArray();
}
}

How to load models in Laravel?

I started studying Laravel and ran into a problem using models. How to load them? For example in CodeIgniter i used it like $model = $this->load->model('some_model'). In Laravel when i call it from controller like Sites::OfUser() it work fine, but when i call Sites::getId() it says that method should be static...
Is it possible to call method without static or i need to create facades for each model?
My model looks like this:
namespace Models;
use Eloquent;
class Sites extends Eloquent {
public function scopeOfUser($query)
{}
public function getId($name)
{}
}
For static method--
$type = Sites ::scopeOfUser($query);
and if you want normal like codeingiter then use--
$model = new Sites ();
$type = $model->scopeOfUser($query);
You can of course make a static method in the model, and do some static work in it (get ID for name or whatever).
That's no problem.
However, you must declare it static if you want to use the ::, which you are doing not.
public static /* <-- this */ function getId($name)
{
// Do work
// return $result;
}
If you want to access a method with ::, you will need to make it a static method or create a Facade.
The reason why Sites::OfUser() is "working" is because you have prefixed that method with scope.
Scopes allow you to easily re-use query logic in your models. To
define a scope, simply prefix a model method with scope.
If you want to use Facades you can follow my answer here on how to create a Facade.

Accessing CI features on non-CI class

So for example, i want to access config on CI from my class library.
Class A {
funcion x() {
$this->config->load('my_config'); // accessing my_config
}
}
that obviously won't work unless you extends and then call parent::__construct().
As far as i know, it can only be done from classes that extend CI_Controller or CI_Model. How to access CI stuff (config, helper, model, etc) on non-CI class ?
Thanks.
How about initiating the class from the construct?
include ("CI_Page.php");
class A {
protected $_CIInstance1;
protected $_CIInstance2;
public function __construct(){
$this->_CIInstance1 = new xxxx();
$this->_CIInstance2 = new yyyy();
}
public function x(){
$this->_CIInstance1->load('my_config');
}
}
You probably want to access the instance of CI as if it were the super variable, $this. In reality what you need is the ability to access the same functionality as $this and in order to do this, you'll need to use $CI =& get_instance();
You can find it directly in the documentation for Creating Libraries

How to get rid of &get_instance() in Codeigniter

I have been using CI for two years now. One thing that really annoys me is the use of &get_instance(). Although it is halpful while we are inside library , helper , presenters , model etc. But everytime loading it is cumborsome. If you forget loading it somewhere and simply use $this->blah->blah() instead of $CI->blah->blah() this makes too much trouble and if you are working online you face the client who is complaining that he sees the error. I have seen in the laravel that you does not need to load the instance anywhere throughout the application. This is because laravel is autoloading all the libraries and models and both are available anywhere in the application. But this seems to me disadvantage why loading classes that are not required in some particular places. This tells me Codeigniter is flexible but still i want an alternative where i dont want to use &get_instance(). Any idea or suggestion ? Please.
In your model or Core model or library
//class MY_Model extends CI_Model
//class SomeLibrary
class Some_model extends CI_Model {
private $_CI;
public function __construct() {
parent::__construct(); //for model or core model
$this->_CI =& get_instance();
}
//if you called attributs who does not exist in that class or parent class
public function __get($key)
{
return $this->_CI->$key;
}
//if you called methods who does not exist in that class or parent class
public function __call($method, $arguments)
{
call_user_func_array(array($this->_CI, $method), $arguments );
}
public function test() {
var_dump($this->some_controller_key);
var_dump($this->some_lib_loaded);
}
}
*NOT TESTED YET
Inspired by an piece of code from the awesome Flexi Auth
//from a Model to keep access of CI_Controller attributs
public function &__get($key)
{
$CI =& get_instance();
return $CI->$key;
}
I was shocked when I saw that ^^
To explain the &__get, i think when you will call this magic method a second time PHP will do not execute it again, but will take his result from the first call.

Add objects to an instance in PHP

Intro
I'm developing an MVC framework, and I've run into a problem. It seems what I was trying to accomplish is known as the Singleton Design method -- initializing classes only once. Remember that I'm trying to put as less code in the controller "acontroller" as possible.
With that said, a final question remains: how can I add objects to an object that has already been instantialized?
It may help to have or at least see actual source instead of just example source, so I have pushed my source to my github. You can find that here: https://github.com/derekmaciel/uMVC
Code explanation
What's happening "under the hood" is first,
The Controller class loads a controller located in /application/controller, in this case "acontroller".
After, the acontroller class loads a model (called "amodel") using the Load class, using $this->load->model("amodel"), which was instantialized in the Controller __construct.
The final outcome of $this->load->model("amodel") is: $controller->amodel =& new Amodel(), where $controller is the Controller instance (not acontroller, because the controller loading the model will vary).
Step 4: Allow acontroller access to models that were loaded (amodel).
Code result
A copy of the current output of these scripts can be found here: http://pastebin.com/EJxuXaki
The first thing you'll notice is that I'm given a warning for using a deprecated assignment. I'm going to focus on the error for now.
The second thing you'll notice is that I first print_r()'d the Controller instance. Inside there is an amodel object, which is want to add to acontroller.
After that, I print_r()'d the $this (acontroller) object. It has everything it got from __construct(), but not amodel.
If I can get acontroller to "see" amodel, then my problem will be solved.
Also:
Is there anyway for me to remove "parent::init()" from the controller acontroller? I only did that so acontroller could have access to both the Load and Model class, but I'm trying to put as less code as possible in acontroller, so having the acontroller have access to Load and Model automatically would help a lot.
I hope I was clear. Thanks for any help
I personally do not think that singleton methods belong within an MVC Framework, the reason for this is because the main objects that are loaded are Models,Libraries and controllers, everything else such as the Router is usually hard coded.
The structure that i would do is create the following classes:
ModelLoader
LibraryLoader
and have them included during system boot, then within your main controller do the following:
class Controller
{
public $library;
public $model;
public function __construct()
{
$this->library = new LibraryLoader();
$this->model = new ModelLoader();
}
}
this would expose the 2 loaders to the child controller, your model/library should hold a private array storing the loaded objects, a little something like this:
class LibraryLoader extends ObjectLoader
{
protected $_path = "/app/library/";
protected $_ext = '.php';
}
class ModelLoader extends ObjectLoader
{
protected $_path = "/app/models/";
protected $_ext = '.php';
}
the object loader would look like so:
class ObjectLoader
{
protected $_path = "/app/";
protected $_ext = '.php';
public function __get($item)
{
/*
* Load item here, the paths above would be overwritten
* store the object in an array, make sure you check if its already loaded
*/
}
}
this is pretty basic, but within your child controllers such as index / home etc you can do the following:
class indexController extends Controller
{
public function index()
{
$this->model->users->getUser(22);
$this->library->security->validateInput("get","key");
//As the objectLoader manages whats loaded, any further calls to the above would
//use the same objects initiated as above.
}
}
This should get you started, its more streamline them using the singleton approach.
I guess you need to include Model.php in your controller.php to be able to use model class.
include 'Model.php';
include 'Load.php';
Since PHP 5.3 you can use the static keyword to instantiate a class
abstract class singleton
{
/**
* Holds an insance of self
* #var $instance
*/
protected static $instance = NULL;
/**
* Prevent direct object creation
*/
final private function __construct() { }
/**
* Prevent object cloning
*/
final private function __clone() { }
final public static function getInstance()
{
if(null !== static::$instance){
return static::$instance;
}
static::$instance = new static();
return static::$instance;
}
}
class myclass extends singleton
{
}
$myclass = myclass::getInstance();
