I'm new to PHPStorm and I imported an existing project in this IDE. Now I receive many warnings like
Method 'query' not found in class
I read about using PHPDoc-blocks in order to declare the origin of variables which are not defined in the current class, but I cannot get out how I should do it for this situation:
class loginModel extends Model{
public function checkLogin(){
[...]
if($this->db->query($sql)){[...]} //Warning as stated above
[...]
}
}
$this->db itself is inheritated from class Model:
class Model{
protected $db;
private function connect(){
$this->db = new PGSQL();
}
}
and therefore can access the public PGSQL method named query.Maybe not that well designed, but how could I solve these messages without downgrading their severity?
class Model{
/**
* #var PGSQL
*/
protected $db;
private function connect(){
$this->db = new PGSQL();
}
}
Docblocks work on properties too

I'm new to OSGI framework and I'm trying to access the 'Derived' Class variable 'publicVariable' from another class 'Derived2' like "Derived.publicVariable" but publicVariable is always shows null. I really appreciate if someone can help me out with this.
Thanks
Manifest file - Derived2
Require-Bundle:com.xxxxxx.Derived1
Java code
abstract class Base {
protected Vector <String> supportedCommands = new Vector <String> ();
protected abstract void initialiseCommands();
}
class Derived extends Base {
private static Derived derivedPlugin = null;
public Derived()
{
derivedPlugin = this;
}
public static Derived getPlugin()
{
return derivedPlugin;
}
public String publicVariable = null;
protected void initialiseCommands()
{
publicVariable = "someData";
System.out.println("Derived" + publicVariable);
}
}
class Derived2 extends Base {
protected void initialiseCommands()
{
supportedCommands.add(Derived.getPlugin().publicVariable);
System.out.println("IMRSAUtilitiesPlugin" +supportedCommands);
}
Also referred below link, which is a similar issue but i'm not using any static variable, it is just a public variable.
how use Singleton object in different class loader....?
The code in the question will not compile. You are trying to access an instance field (publicVariable in class Derived) in a static way, i.e. Derived.publicVariable.
OSGi does not change the semantics of the Java language, and if you cannot even compile your code then OSGi will certainly not be able to run it.
In my controller(s), instead of fetchingAuth::id() in each method, I've set up an $id property in the controller's class and fetched it once in the constructor. then, in the rest of the methods i'm just refering $this->id, is it considered safe or am I doing something wrong?
Code Sample: http://pastebin.com/pvju54eh
What you could do is inject the Guard instance in your controller and then assign the currently logged in user (if there is one) to a class property:
<?php namespace App\Http\Controllers;
use Illuminate\Contracts\Auth\Guard;
class SomeController extends Controller
{
protected $auth;
protected $user;
public function __construct(Guard $auth)
{
$this->auth = $auth;
$this->user = $this->auth->user();
}
public function someMethod()
{
// Get logged in user’s ID
$userId = $this->user->id;
}
}
I do not see any major problems with this approach even though I have not seen approach used often.
Myself I find it easier to get the $request->user() in controller from Request though.
I have a Holder class that returns a DataList of type BaseClass. The objects are really SearchClass objects. How do I convert the DataList so that I can filter by the SearchClass fields.
class SearchClass extends BaseClass(){
public static $db = array('myField' => 'Int');
}
abstract class Holder{
abstract protected function myList();
}
$holder = new ConcreteHolder();
$holder->myList()->filter('myField',1);
The easiest way is:
class Holder extends DataObject {
public function myList(){
return SearchClass::get()->filter('baseField', 'aValue');
}
}
After a bit more time here's the solution I came up with.
public function convert($list){
$ids = $list->filter('ClassName', 'SearchClass')->getIDList();
return SearchClass::get->byIDs($ids);
}
I am trying to call a parent method from its child which has the same method name. Doing so results in a strict standards error. There's an easy solution of renaming the child method. However, is there a way to keep the names of the two methods identical without a standards warning? Thanks.
Strict standards: Declaration of Child::getContentFromDb() should be compatible with Parent::getContentFromDb($id) in /foo/Child.class.php on line xxx
Pseudo-code example:
class Parent {
protected function getInfoFromDb($id) {
return $infoFromDb;
}
}
class Child extends Parent {
public static $id = xx;
public $info = array();
public function __construct() {
$this->info = $this->getInfoFromDb();
}
public function getInfoFromDb() {
// the line below causes the problem
return parent::getInfoFromDb(self::$id);
}
}
Your method override should take the same parameter list as the one you are overriding.
e.g.
class ParentClass {
protected function getInfoFromDb($id) {
return "INFO FROM DB:" . $id;
}
}
class Child extends ParentClass {
public static $id = "xx";
public $info = array();
public function __construct() {
$this->info = $this->getInfoFromDb();
}
/**
* #param specific ID, or do not set for default action.
* #return string
*/
public function getInfoFromDb($id = false) {
return parent::getInfoFromDb(self::$id);
}
}
I'm switching a Zend Framework application from mono-user to multi-user.
What is the best approach to include the user scope in the controllers ?
One way would be to add the user id in each methods in every controllers:
/application/controllers/IndexController.php
...
public function indexAction() {
$params['user_id'] = Zend_Auth::getInstance()->getIdentity()->id;
$listHelper->readItems($params);
}
...
An other one would be to create a new User model and fetch his items :
/application/controllers/IndexController.php
...
public function indexAction() {
$userModel = new application_models_user();
$userModel->find(Zend_Auth::getInstance()->getIdentity()->id);
$userModel->readItems();
}
...
I'm wondering what's the best approach that would allow me to write minimal code and if you have another idea to "automagically" add the user scope (db scope, plugin...).
Create an abstract class by extending Zend_Controller_Action
abstract class My_Controller_Action extends Zend_Controller_Action {
private $userModel;
public function getUserModel() {
if(is_null($this->userModel)) $this->userModel = new application_models_user();
return $this->userModel;
}
public function getUserId() {
return $this->getUserModel()->find(Zend_Auth::getInstance()->getIdentity()->id);
}
}
Now use this class as base class for your controllers.
