# Digipolis Symfony Setting Bundle



## Introduction



This library allows you to add extra values for instances of predefined entity types.

These extra values and their characteristics are dynamicly defined in other bundles with the usage of data providers.

Based on these providers your form will automatically build and do the necessary validations.

After saving, these values (strings, integers, array collections, ...) are easily accessible with the services we provide in this bundle so they can be used throughout the project.



## Compatibility



This bundle is compatible with all Symfony ^5.0 releases.



## Installation



You can use composer to install the bundle in an existing symfony project.



```

composer require digipolisgent/setting-bundle

```



For more information on how to install symfony bundles, please see

[the Symfony documentation about bundles](https://symfony.com/doc/current/bundles.html)



There are no routes to register or other mandatory configuration options.



## Before reading this documentation



If you are not familiar with symfony we suggest reading the [Symfony 5 documentation](https://symfony.com/doc/5.3/index.html).



## Entity types



Entity types are the the entities we want to assign extra values to. We define these by using the SettingImplementationTrait.

This requires the ```getSettingImplementationName``` method to be implemented too. We use this name to access the entity types.



```php

id;

    }



    use SettingImplementationTrait;



    /**

     * @return string

     */

    public static function getSettingImplementationName()

    {

        return 'foo';

    }

}

```



The trait will



- Make sure the database is updated using the ```DynamicSettingImplementationRelationSubscriber```

- A ```SettingEntityType``` entity is added to the database

- Extra data can be added to the entity using the ```DataValueService```

- The ```FormService``` adds and processes the extra configuration if the set data is an entity using this trait



## Field types



These are the services that will define how an extra configured field behaves in a form and how the data is presented when we want to use it throughout the application.



A service needs to extend from the ```AbstractFieldType```. As an example we use one of the predefined field types.



```php

 'bar',

                'label' => 'My foo label',

                'required' => true,

                'field_type' => 'foo',

                'entity_types' => ['foo'],

            ],

        ];

    }

}

```



All keys are checked



- key : this is the key you can access the extra setting with if you need it at a later time

- label : this is the label that will be used in forms

- field_type: this is the name of the field type that was defined previously

- entity_types: this is a list of all entity type names that you want this to be available to



## Loading data types and entity types



For the changes to take effect the database needs to be updated. The following command will fill the database.



```bash

bin/console doctrine:fixtures:load --append

```



## Form building



You can add these extra settings to your form by adding an event subscriber to your form builder.

This subscriber will make sure the form is built and processed as defined in the field types.

If the data set to the form is not an entity type nothing will happen. This way you can also use the subscriber in generic forms.



```php

formService = $formService;

    }



    /**

     * @param FormBuilderInterface $builder

     * @param array $options

     */

    public function buildForm(FormBuilderInterface $builder, array $options)

    {

        parent::buildForm($builder, $options);

        $builder->addEventSubscriber(new SettingFormListener($this->formService));

    }

}



```



## Data value service



To access these values in other scripts we can use the ```DataValueService```.



For example. If you want the the value with key ```bar``` from an instance of the ```foo``` class that you previously saved using the form you do the following.



```php

$value = $this->dataValueService->getValue($foo, 'bar');

```



If after some data manipulation you want to update this value and make it visibile in the form you can also store the value.



```php

$this->dataValueService->storeValue($foo, 'bar', 'manipulated string');

```



## Advanced field type usage



You can also use the field type to store and manipulate entities since you can inject other services here. This is an example where we make a checkbox list of ```bar``` entities.



```php

entityManager = $entityManager;

    }



    public function getFormType(): string

    {

        return CollectionType::class;

    }



    /**

     * @param $value

     * @return array

     */

    public function getOptions($value): array

    {

        $options = [];

        $options['entry_type'] = BarFormType::class;

        $options['allow_add'] = true;

        $options['allow_delete'] = true;

        $options['by_reference'] = false;

        $options['prototype'] = true;

        $options['prototype_data'] = new Bar();



        $ids = json_decode($value, true);



        $barRepository = $this->entityManager->getRepository(Bar::class);



        $data = [];



        if (!is_null($ids)) {

            foreach ($ids as $id) {

                $data[] = $barRepository->find($id);

            }

        }



        $options['data'] = $data;



        return $options;

    }



    /**

     * @return string

     */

    public static function getName(): string

    {

        return 'bar_checkbox';

    }



    /**

     * @param $value

     * @return string

     */

    public function encodeValue($value): string

    {

        $barIds = [];



        foreach ($value as $bar) {

            $this->entityManager->persist($bar);

            $capistranoSymlinkIds[] = $bar->getId();

        }



        return json_encode($barIds);

    }



    public function decodeValue($value)

    {

        $barRepository = $this->entityManager->getRepository(Bar::class);



        $ids = [];



        if ($value == '' || is_null($ids)) {

            return [];

        }



        $bars = [];

        $ids = json_decode($value, true);



        foreach ($ids as $id) {

            $bars[] = $barRepository->find($id);

        }



        return $bars;

    }

}



```



Using ```bar_checkbox``` as a field type in your data type provider will :



- Give a list of checkboxes with all bar entities when you generate a form

- The ```getValue``` function in the ```DataValueService``` will give you a list of ```Bar``` entities

- The ```storeValue``` function in the ```DataValueService``` gives you the possibility to save a list of ```Bar``` entities



## Advantages



- You can have extra properties for the entities that appear and disappear if you activate or deactivate bundles.

- The field types give the possibility to reuse code multiple times.

- You can change the structure in a matter of seconds by changing the dataprovider array
