Hello DnaExchangeBundle!

DnaExchangeBundle is a way to provide dna stamps to content and users. With this dna the bundle can provide related content or related users.

Install the package with:

composer require dnaklik/dna-exchange-bundle

And... that's it! If you're not using Symfony Flex, you'll also need to enable the DnaKlik\DnaExchangeBundle\DnaKlikDnaExchangeBundle in your AppKernel.php file.

Usage

To provide content ans users with dna stamps add this code in your controller. If there is no user logged in the DNA stamps are stored in a session.

// src/Controller/SomeController.php

use DnaKlik\DnaExchangeBundle\Service\DnaKlikExchange;
use Symfony\Component\HttpFoundation\Request;
// ...

class SomeController
{
    
    public function __construct(Request $request, DnaKlikExchange $dnaKlikExchange, DnaExchangeContentRepository $dnaExchangeContentRepository)
    {
        $this->dnaKlikExchange = $dnaKlikExchange;
        $this->dnaExchangeContentRepository = $dnaExchangeContentRepository;
    }
    
    public function detail()
    {
        $stamp = $this->dnaKlikExchange->getStamp($request);

        // ...
    }
}

## To find related content:
    public function relatedContent(Request $request): response
    {
        $items = $this->dnaKlikExchange->getRelatedContent($request, 30);
        foreach($items as $values) {
            $values["slug"];
            $content = $this->doctrine
                ->getRepository(Content::class)
                ->findOneBy(array("urlName" => $slugParts[2]));
            $values["matchCorr"];
            foreach($values["stamps"] as $stamp => $stampCount) {
                if (isset($values["matchStamps"][$stamp])) {
                    $dna .= "<span class='match'>".$stamp." (".$stampCount.")</span> ";
                }
                else {
                    $dna .= $stamp." (".$stampCount.") ";
                }
            }
            $values["totalStampCount"]);
        }
    }

## An array with slugs is returned. You can use the slugs to retrieve the related content from your own application

You can also access this service directly using the id dnaklik_dna_exchange.dnaklik_exchange.

Configuration

Some optional parameters can be configured directly by creating a new config/packages/dnaklik_dna_exchange.yaml file. The default values are:

# config/packages/dnaklik_dna_exchange.yaml
# crossover value
crossOver:    8

# max number off stamps per item
maxStamps: 64

stamp_provider: App\Service\CustomDnaKlikStampProvider

Extending the Stamp List

If you're feeling especially creative and excited, you can customize dna_exchange to provide it with extra content!

To do that, create a class that implements DnaKlikStampProvider: Example of your own stampprovider with content from colors

namespace App\Service;

use DnaKlik\DnaExchangeBundle\Service\DnaKlikStampProvider;

class CustomDnaKlikStampProvider extends DnaKlikStampProvider
{
    public function getContent(): array
    {
        $result = $this->dnaExchangeContentStampRepository->StampsInContent();
        foreach($result as $index => $content) {
            $slugParts = explode("/", $content["slug"]);
            $color = $this->manager
                ->getRepository(Color::class)
                ->findOneBy(array("urlName" => $slugParts[2]));
            $result[$index]["property"] = $color->getColor();
        }
        return $result;
    }

    function getContentFromId($id) {
        $result = $this->dnaExchangeContentRepository->findBy(array("id" => $id),array('id'=>'DESC'),3,0);
        foreach($result as $index => $content) {
            $slugParts = explode("/", $content->getSlug());
            $color = $this->manager
                ->getRepository(Color::class)
                ->findOneBy(array("urlName" => $slugParts[2]));
        }
        return $color;
    }

    public function findMatchItems($dna, $max)
    {
        $items = $this->matchDna->findMatchItems($dna, $max);
        foreach($items as $index => $item) {
            $slugParts = explode("/", $item["slug"]);
            $color = $this->manager
                ->getRepository(Color::class)
                ->findOneBy(array("urlName" => $slugParts[2]));
            $items[$index]["property"] = $color->getColor();
        }
        // dump($items);
        return $items;
    }
}

There is also an admin to evaluate the progress of the dna exchange: The route to this admin can be configured by creating a new config/routes/dnaklik_dna_exchange.yaml file.

_dna_exchange:
  resource: '@DnaKlikDnaExchangeBundle/Resources/config/routes.xml'
  prefix: /dna

The url to this admin is: <your_url>/dna/exchange/admin
