PHP - Questions On Inheritance

Hello,

I'm attempting to build a Model View Controller and I've run into some issues with inheriting objects / extending classes. The application is focused around a "SuperObject", which contain instantiated libraries, helpers, controllers, models and views.

I current have a Base class, which is effectively the "SuperObject". Previously I called the function GetInstance() within my model to get an instance of the SuperObject and assign it to a variable. So, $this->Instance->(The Object)->(The Method)();

However, I want to remove the need for that variable $this->Instance and just have $this->(The Object)->(TheMethod)();

And so, If you see my Controller class, libraries are instantiated as $this->Object which works perfectly. If from, within my controller I was to load the Model class. For example, $this->Loader->Library('Model'); when that model becomes instantiated, even though an extension of the Base class, I cannot use the libraries I instantiated in my controller.

And of course there is a Fatal Error: Fatal error: Call to a member function UserAgent() on a non-object

Code: [Select]
<?php

class Base
{
private static $Instance;

public function Base()
{
self::$Instance =& $this;
}

public static function &GetInstance()
{
return self::$Instance;
}
}

function &GetInstance()
{
return Base::GetInstance();
}

Code: [Select]
<?php

class Controller extends Base
{
function Controller()
{
parent::Base();
$this->Initialize();
}

function Initialize()
{
$Array = array(
'Uri',
'Loader',
'Router',
'Database',
);

foreach($Array as $Object)
{
$this->$Object = loadClass($Object);
}

}
}
Code: [Select]
<?php

class Model extends Base
{
function Model()
{
parent::Base();
echo $this->Input->UserAgent();
}

    }

Code: [Select]
<?php

class Home extends Controller
{
function Home()
{
parent::Controller();
}

function index()
{
$this->Loader->Library('Session');
$this->Loader->Library('Model');

$Data = array(

'Controller' => $this->Router->FetchClass(),
'Title' => ucfirst($this->Router->FetchClass())

);

$this->Loader->View('meta',$Data);
$this->Loader->View('header',$Data);
$this->Loader->View('home');
$this->Loader->View('footer');
}
}

Any input would be appreciated!

I wish to create and store in a DB three objects which are created using injection;

$myAObject=new BaseEntity(new InjectedThingA());
$myBObject=new BaseEntity(new InjectedThingB());
$myCObject=new BaseEntity(new InjectedThingC());

BaseEntity is defined by SQL table base_entity and my three injected objects InjectedThingA,  InjectedThingB, and InjectedThingC are each defined by SQL tables injected_thing_a, injected_thing_b, injected_thing_c, respectively.  Each of these injected tables has autoincrement column id plus whatever other columns, and base_entity includes a column injected_thing_id.  But this won't work since this ID is not unique across InjectedThings and also poor since there is no foreign key, so instead I do the following.

InjectedThingA extends AbstractInjectedThing
InjectedThingB extends AbstractInjectedThing
InjectedThingC extends AbstractInjectedThing

Then I add an autoincrement id column to AbstractedInjectedThing and place a one-to-one constraint from column id in InjectedThingA,  InjectedThingB, and InjectedThingC to column id in AbstractedInjectedThing.

So, I still need to use inheritance, right?  I don't think that this type of inheritance brings the baggage which MyInheritedEntity extends BaseEntity does and I am okay with it, but just want to make sure I am doing this right.

Thanks

Trying to create a model where Parent1 and Parent2 extend Grandparent, and Child1_1 and Child1_2 extend Parent1 as well as Child2_1 and Child2_2 extend Parent2.

I set up my definitions:

Grandparent:
    type: entity
    table: grandparent_table
    inheritanceType: JOINED
    discriminatorColumn:
        name: discriminator_column_grandparent
        type: string
    repositoryClass: GrandParent
    id:
        id:
            type: integer
            generator:
                strategy: AUTO
    fields:
        GrandParent_Item1:
            type: string
        GrandParent_Item2:
            type: string
Parent1:
    type: entity
    table: parent_table1
    extends: Grandparent
    inheritanceType: JOINED
    discriminatorColumn:
        name: discriminator_column_parent1
        type: string
    id:
        id:
            associationKey: true
    fields:
        Parent1_Item1:
            type: string
        Parent1_Item2:
            type: string
Parent2:
    type: entity
    table: parent_table2
    extends: Grandparent
    inheritanceType: JOINED
    discriminatorColumn:
        name: discriminator_column_parent2
        type: string
    id:
        id:
            associationKey: true
    fields:
        Parent2_Item1:
            type: string
        Parent2_Item2:
            type: string
Child1_1:
    extends: Parent1
    type: entity
    table: child1_1_table
    id:
        id:
            associationKey: true
    fields:
        Child1_1_Item1:
            type: string
        Child1_1_Item2:
            type: string
Child1_2:
    extends: Parent1
    type: entity
    table: child1_2_table
    id:
        id:
            associationKey: true
    fields:
        Child1_2_Item1:
            type: string
        Child1_2_Item2:
            type: string
Child2_1:
    extends: Parent2
    type: entity
    table: child2_1_table
    id:
        id:
            associationKey: true
    fields:
        Child2_1_Item1:
            type: string
        Child2_1_Item2:
            type: string
Child2_2:
    extends: Parent2
    type: entity
    table: child2_2_table
    id:
        id:
            associationKey: true
    fields:
        Child2_2_Item1:
            type: string
        Child2_2_Item2:
            type: string

 And then generate my entities:       

$ vendor/bin/doctrine orm:generate-entities -vvv src

 Processing entity "Child1_1"
 Processing entity "Child1_2"
 Processing entity "Child2_1"
 Processing entity "Child2_2"
 Processing entity "Grandparent"
 Processing entity "Parent1"
 Processing entity "Parent2"


 [OK] Entity classes generated to "/var/www/doctrine/src"

Note that I needed to manually edit the Parent1 and 2 classes to extend Grandparent as well as the individual Child classes to extend their applicable Parent.

Next, I create the schema:

$ vendor/bin/doctrine orm:schema-tool:create --dump-sql

 The following SQL statements will be executed:

     CREATE TABLE child1_1_table (id INT NOT NULL, Child1_1_Item1 VARCHAR(255) NOT NULL, Child1_1_Item2 VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     CREATE TABLE child1_2_table (id INT NOT NULL, Child1_2_Item1 VARCHAR(255) NOT NULL, Child1_2_Item2 VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     CREATE TABLE child2_1_table (id INT NOT NULL, Child2_1_Item1 VARCHAR(255) NOT NULL, Child2_1_Item2 VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     CREATE TABLE child2_2_table (id INT NOT NULL, Child2_2_Item1 VARCHAR(255) NOT NULL, Child2_2_Item2 VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     CREATE TABLE grandparent_table (id INT AUTO_INCREMENT NOT NULL, GrandParent_Item1 VARCHAR(255) NOT NULL, GrandParent_Item2 VARCHAR(255) NOT NULL, discriminator_column_grandparent VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     CREATE TABLE parent_table1 (id INT NOT NULL, Parent1_Item1 VARCHAR(255) NOT NULL, Parent1_Item2 VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     CREATE TABLE parent_table2 (id INT NOT NULL, Parent2_Item1 VARCHAR(255) NOT NULL, Parent2_Item2 VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;
     ALTER TABLE child1_1_table ADD CONSTRAINT FK_3445750EBF396750 FOREIGN KEY (id) REFERENCES grandparent_table (id) ON DELETE CASCADE;
     ALTER TABLE child1_2_table ADD CONSTRAINT FK_5AD6F93BF396750 FOREIGN KEY (id) REFERENCES grandparent_table (id) ON DELETE CASCADE;
     ALTER TABLE child2_1_table ADD CONSTRAINT FK_DC849CBBF396750 FOREIGN KEY (id) REFERENCES grandparent_table (id) ON DELETE CASCADE;
     ALTER TABLE child2_2_table ADD CONSTRAINT FK_3C205356BF396750 FOREIGN KEY (id) REFERENCES grandparent_table (id) ON DELETE CASCADE;
     ALTER TABLE parent_table1 ADD CONSTRAINT FK_5386E15BBF396750 FOREIGN KEY (id) REFERENCES grandparent_table (id) ON DELETE CASCADE;
     ALTER TABLE parent_table2 ADD CONSTRAINT FK_CA8FB0E1BF396750 FOREIGN KEY (id) REFERENCES grandparent_table (id) ON DELETE CASCADE;

I see how Grandparent has discriminatorColumn discriminator_column_grandparent as expected.

But why doesn't Parent1 and Parent2 have discriminatorColumn's discriminator_column_parent1 and discriminator_column_parent2?

Note that I've also tried making Grandparent, Parent1, and Parent2 abstract but get the same results.  I've also messed around with Mapped Superclasses, but I don't think they are applicable for my use (correct me if you think I am wrong).

Thanks!

I am doing something stupid, and just can't see it and hoping someone has better eyes than mine.  I have two Doctrine entities which extend another class using single class inheritance, but when retrieving the collection of either of the two child classes, I get the collection of the parent (i.e. combination of both child classes).  I've experimented with making the parent abstract and not including it in the discriminator map but no change.  In hopes to identifying my mistake, I created a new Symfony project with just the relevant classes and show all steps below.

Initial install by running the following:

symfony new test
composer update
composer require doctrine/orm
composer require migrations
composer require maker --dev
composer require security

Using "php bin/console make:user", I created three users: AbstractUser, OwnerUser, VendorUser.  I then edited all three entities and the owner and vendor repositories as follows:

<?php

namespace App\Entity;

use App\Repository\AbstractUserRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;

/**
 * @ORM\Entity(repositoryClass=AbstractUserRepository::class)
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorColumn(name="discr", type="string")
 * @ORM\DiscriminatorMap({"owner" = "OwnerUser", "vendor" = "VendorUser", "abstract" = "AbstractUser"})
 */
class AbstractUser implements UserInterface
{
    // No changes made
}

 

<?php

namespace App\Entity;

use App\Repository\OwnerUserRepository;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass=OwnerUserRepository::class)
 */
class OwnerUser extends AbstractUser
{
}

 

<?php

namespace App\Entity;

use App\Repository\VendorUserRepository;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass=VendorUserRepository::class)
 */
class VendorUser extends AbstractUser
{
}

No change to AbstractUserRepository.

<?php

namespace App\Repository;

class OwnerUserRepository extends AbstractUserRepository
{
}

 

<?php

namespace App\Repository;

class VendorUserRepository extends AbstractUserRepository
{
}

Then I migrated the DB.

php bin/console doctrine:schema:drop --full-database --force
rm migrations/*
php bin/console make:migration
php bin/console doctrine:migrations:migrate

Next I created two OwnerUsers and one VendorUser using a command script I wrote shown at the end of this post.

# php bin/console app:tester create OwnerUser roles=[]
# php bin/console app:tester create OwnerUser roles=[]
# php bin/console app:tester create VendorUser roles=[]

Checked the PostSQL database.

Next, I retrieved the entities using Doctrine along with the beforementioned test script.

As seen, when requesting a collection of either OwnerUsers or VendorUsers, I am retrieving the combination of both collections.  I am sure it is totally user (i.e. me) error, but just don't see it.  Are you able to see my stupid mistake?  Thanks

For solely to reduce duplicated code and when injection isn't applicable, should one use inheritance or traits?

<?php
abstract class BaseClass
{
    private $id, $name;
    public function __construct(int $id, string $name) {
        $this->id=$id;
        $this->name=$name;
    }

    public function getId():int
    {
        return $this->id;
    }

    public function getName():string
    {
        return $this->name;
    }
}

<?php
class A extends BaseClass{}
class B extends BaseClass{}
class C extends BaseClass
{
    private $foo;
    public function __construct(int $id, string $name, Foo $foo) {
        parent::__construct($id, $name);
        $this->foo=$foo;
    }
    public function getFoo():Foo {
        return $this->foo;
    }
}

<?php
trait MyTrait
{
    private $id, $name;
    public function __construct(int $id, string $name) {
        $this->id=$id;
        $this->name=$name;
    }

    public function getId():int
    {
        return $this->id;
    }

    public function getName():string
    {
        return $this->name;
    }
}

<?php
class A
{
    use MyTrait;
}
class B
{
    use MyTrait;
}
class C
{
    use MyTrait;
    private $foo;
    public function __construct(int $id, string $name, Foo $foo) {
        $this->id=$id;
        $this->name=$name;
        $this->foo=$foo;
    }
    public function getFoo():Foo {
        return $this->foo;
    }
}

Howdy,

I am new to SEO. Could you please help me? 

1. I like to post programming tutorials to both my website & various programming forums. Is that going to screw up my website's ranking in Google?

2. My editor of my history website who sometimes posts essays there also posts them in some history forums. Is that bad for SEO?

3. I made a Facebook page for my history website. It says there "Promote your page" basically you pay $5 for around 100 likes. Has anyone tried that? Does it work? Because $5 seems like little money for additional 100 likes which will increase the traffic considerably.

Thank you so much for the help!

Hello everyone, I have been doing web developing for a little while and just recently decided to make the leap to developing standalone applications.  I started learning C++ and JAVA for this purpose, but quickly learned that PHP can also be used to this end, and since I am quite familiar with PHP, I thought it would make sense to start with PHP GTK.  But before I jump right in, I have a few questions that I would greatly appreciate some answers for:

Does PHP have any significant advantages/disadvantages over lower level languages such as C++ ?  I would imagine that PHP being originally designed for web programming would be less suited for stand alones.

I'm a little confused as to whether the GTK is a graphical user interphase software, the likes of QT and Netbeans,  or is it a markup language like HTML, where the widgets are generated with text commands?  Please I need a little clarification on that.  Also are there any other tools that need to be downloaded to get started besides the GTK?

Finally, am I supposed to learn OOP PHP to get going or is traditional procedural PHP sufficient?


Answers to any or all of the above questions and any other advice would be highly appreciated.

Thanks.

I've been coding PHP for some time and would consider myself to be at an intermediate level. I can write code to do what I need but it's probably not the best way to do it. I rarely see any code that I am not able to read, understand, or follow. I've created modifications for everything from vBulletin, WordPress, Kayako Support Suit, Magento, and more.

However, I've never really built a strong understanding around OOP. For example, let say you have the following classes:
_main
  -  db
  -  admin
  -  -  modules
  -  -  -  dashboard

How would you share the db connection with the dashboard class? I've been trying to read up on Dependency Injections and Singletons but I haven't found an article that has explained it on a level that I can understand. I get a feeling that most people who use OOP in PHP have a background in Java or C++ and are much more familiar with everything.

Could someone please explain this to me in simple terms or link me to an extremely well explained article that I'd be able to understand without a background in computer science?
Thanks

Hi. I'll like to ask few questions about PHP, as I think they are related to it.   I've came across some webpages, what I've spotted is that a webpage displays content but each "page" has different argument and there is no filename. For example: "http://www.website.com/?home" is home-like webpage, by changing "/?home" to "/?anotherpage" land me on some other webpage on their website and so on. My question is how is it done? Is it done from PHP? Another question I wanted to ask is.. I went on InvisionPower.Board forum (such as this PHP Freaks  ). How to force "folders" to be displayed as "files"? For example: "http://forums.phpfre...ks-on-facebook/" which links to a thread.   Thanks in advance 

A few questions about mod_rewrites...

1.) If I want to determine if the URL ends with either "list" or "gallery", and then take appropriate action, does the code below look correct?

	RewriteRule shop/(.+)/([list|gallery])$  shop/catalog.php?category=$1&view=2 [L]
	

 

2.) Is it bad to use mod_rewrites to determine how your website branches?

For example...

	RewriteRule shop/music/(.*)$  go somewhere [L]
	RewriteRule shop/movies/(.*)$  go somewhere else [L]
	RewriteRule shop/books/(.*)$  go yet somewhere else [L]
	

 

 

I basically have a picture uploading system for users. I have two questions:

1) What CHMOD should I use for the folders that are there for uploading files to? Currently it is 755, but I want it to be accessible and safe.

2) When I use the standard mkdir() function to create folders in my main parent folder, the folders don't get created. Is this because my parent folder is CHMOD 755?

Thanks

So I have been slowly working on a custom forum. I have recently been trying to implement an achievement system.   For the most part achievements would work based on the users   amount of posts amount of characters in a post amount of replies on a post time past from the users join date.   I was hoping to find out how I could put an entry into a database field based on the above.   Any help would be greatly appreciated    

1. If I start a new project, should I use Laravel 5.0(dev) or 4.2? 2. How easy is it to upgrade from between major version like that? 3. Any design recommendations for daily with authentication and accounts?

Hey guys! im currently learning javascript, PHP and SQL. I have a pretty solid understanding of HTML and CSS. I want to make a site similar to facebook (a good facebook). this is going to be a big project and i plan on moving to a bigger server system in a year or so to keep up with demands.    Heres how the site will function:    1. Basic registration/splash page. I understand that the finished form is sent to a php file on the server side, correct?  (ill change my server name files of course)   2. after the registration page, while the user is logged in with their new account, there are 3 pages after that that explain what the website is all about and how to use it. the last page allows the user to setup their profile information, ask friends to join, and asks what type of things they like. After the last page, it sends the user to their main control panel, where social media feed can be seen, friends and online chats, news, advertisements, links, pages and groups (think facebook and linkedin)   3. the user will have the ability to look at their profile (not the control panel), and of course switch back to their control panel. social media, friends, groups and ads will also be on their individual profile page as well.   4. i want the site to have two views: a standard view and an enhanced view. the enhanced view will reposition divs and all that stuff so they can see a background image (either stock or one they uploaded) this image will eventually change to an animated image of a 3d environment.   5. the site is going to be heavily social media based. This means social media feeds, image uploading, a structured comment system, a friend system, search functions and targeted advertising.   This is obviously a lot to ask, but since their is so much to learn related to PHP and SQL, can someone point me to the right tutorials on how to get these things done? I am currently learning javascript, PHP and SQL on lynda.com. Expect me to be on this forum a lot and asking a lot of questions. Thanks for any help.
