README
This bundle is built to allow users to define configuration options, useful in admin panels.
Get rid of the business logic variables in your ENV
or parameters.yml
file !
Available features:
- Define multiple configuration entries available for the users
- Retrieve configuration values anywhere in your code for business logic
- Use or create custom parameter types for a better user experience
Installation
The best way to install this bundle is to rely on Composer:
$ composer require sherlockode/configuration-bundle
Setup
Enable the bundle in the kernel
<?php // config/bundles.php return [ // ... Sherlockode\ConfigurationBundle\SherlockodeConfigurationBundle::class => ['all' => true], ];
You will need a Parameter
entity in order to store the configuration values in the database.
<?php namespace App\Entity; use Doctrine\ORM\Mapping as ORM; use Sherlockode\ConfigurationBundle\Model\Parameter as BaseParameter; #[ORM\Entity] #[ORM\Table(name: 'parameter')] class Parameter extends BaseParameter { #[ORM\Id] #[ORM\Column(name: 'id', type: 'integer')] #[ORM\GeneratedValue(strategy: 'AUTO')] protected int $id; #[ORM\Column(name: 'path', type: 'string')] protected string $path; #[ORM\Column(name: 'value', type: 'text', nullable: true)] protected ?string $value = null; }
Configuration
The entity class you just created must be set in the bundle's configuration:
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: entity_class: parameter: App\Entity\Parameter
Now you are free to define any configuration entry you'd like by using the parameters
key:
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: entity_class: parameter: App\Entity\Parameter parameters: contact_email: label: My customer service contact email type: simple # the "simple" type renders by default as a TextType form element max_user_login_attempts: label: Max login attemps before account blocking type: simple options: # it is possible to customize the form type to use for a "simple" parameter type subtype: Symfony\Component\Form\Extension\Core\Type\IntegerType sales_date: label: Sales start date type: datetime options: required: false
Translations
By default parameters labels are not translated in the form provided by the bundle.
If you want to use translations you can define a translation_domain
key globally and/or for each parameter
and use your translation key as the label.
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: translation_domain: my_app_domain # default domain is false (no translation) parameters: contact_email: label: customer.contact_email type: simple translation_domain: my_param_domain # overrides the global domain sales_date: # no translation domain, fallback to my_app_domain label: sales.start_date type: datetime
Options
Each type of field may accept a various range of options that can be defined under the options
key.
Every field may have a required
option to define if the input field will be required (it defaults to true).
The other options are up to the field and its needs. For instance, the choice field allow to define
multiple
and choices
options in order to customize the form.
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: parameters: guess_access: label: Allow guest access type: choice options: required: true multiple: true choices: yes: 1 no: 0
Every field may also have a constraints
option to define validation constraints.
You can use Symfony built-in constraints or add your own:
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: parameters: website_title: label: Website title type: simple options: required: true constraints: - NotBlank: ~ - Length: min: 8 max: 255 minMessage: 'This field must be at least {{ limit }} characters long' maxMessage: 'This field must be at least {{ limit }} characters long' - App\Validator\ContainsAlphanumeric: message: "The website title can only contains alphanumeric characters"
Usage
Default controller
All configured parameters can be edited with the provided controller.
You may import the routing file in order to access it, the listing will be available at URI /parameters
.
# config/routing.yaml sherlockode_configuration: resource: "@SherlockodeConfigurationBundle/Resources/config/routing.xml"
You can also modify the default template used by this controller with the templates
configuration entry point:
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: templates: edit_form: 'Parameter/my_parameter_list.html.twig'
Custom code for the Form
If you have more specific usages, you can build your own form using the ParametersType
,
a FormType
dedicated to editing the parameters.
The model data for the form is an associative array of the paths and existing values.
You can get the existing parameters from the DB using the service sherlockode_configuration.parameter_manager
:
<?php use Sherlockode\ConfigurationBundle\Form\Type\ParametersType; use Sherlockode\ConfigurationBundle\Manager\ParameterManagerInterface; // $parameterManager has been injected /** @var ParameterManagerInterface $parameterManager */ $data = $parameterManager->getAll(); // or using an associative array: // $data = ['contact_email' => 'me@example.com', 'max_user_login_attempts' => 5]; $form = $this->createForm(ParametersType::class, $data); // handle form submission $form->handleRequest($request); if ($form->isSubmitted() && $form->isValid()) { $params = $form->getData(); foreach ($params as $path => $value) { $parameterManager->set($path, $value); } $parameterManager->save(); } //...
Access configuration values
You are now able to retrieve any configuration value by using the get
method from the parameter manager.
It is possible to provide a default value to return if the entry has not been set yet.
$email = $parameterManager->get('contact_email'); $maxAttempts = $parameterManager->get('max_user_login_attempts', 5);
Import / export from the browser
You can export or import parameters in a yaml file. You have two routes for these operations:
sherlockode_configuration.export
sherlockode_configuration.import
You also can customize the import form template by defining your own in the configuration:
# config/packages/sherlockode_configuration.yaml sherlockode_configuration: templates: import_form: 'Parameter/my_import_form.html.twig'
Import / export from CLI
You can export or import your parameters with these two Symfony commands:
sherlockode:configuration:export
sherlockode:configuration:import
These commands rely on the Symfony secrets mechanism. So be sure to generate your credentials with the following command:
$ php bin/console secrets:generate-keys
Events
When parameters are saved in database, multiple events are dispatched
Sherlockode\ConfigurationBundle\Event\PreSaveEvent
is dispatch before saving parameters;Sherlockode\ConfigurationBundle\Event\SaveEvent
is dispatch just after saving new parameters values in database;Sherlockode\ConfigurationBundle\Event\PostSaveEvent
is dispatch just after the SaveEvent. It can be useful for customizing redirection or adding flash message for example;
Field types
Default types
Here are the field types provided in the bundle, located in the namespace Sherlockode\ConfigurationBundle\FieldType
:
- simple
- checkbox
- choice
- datetime
- entity
- image
- password
Custom Field types
In order to add custom field types, you should create a service implementing the FieldTypeInterface
interface
and tag it with sherlockode_configuration.field
(or use autoconfiguration).
The getName()
return value is the alias of the field type to use in the configuration (like simple
or choice
).
Using transformers
Due to the format of the Parameter entity in the database (the value is stored as a string, whatever the parameter type), complex values cannot be stored directly. For instance, we can serialize an array to fit the string type, or we may store the ID of a database entity. The process may vary depending on your needs and the value to store, but the application needs to be aware of the process to transform the PHP data into a string and the opposite process. This is done through transformers.
A transformer is an object implementing the Sherlockode\ConfigurationBundle\Transformer\TransformerInterface
.
The interface has two methods transform
and reverseTransform
, similarly to the transformers used by Symfony in the Form Component.
The transform
method takes the string representation and returns the PHP value,
when the reverseTransform
takes your PHP value and returns back the corresponding scalar value.
In order to be used, an instance of the transformer should be returned by the getModelTransformer
method of the corresponding field type. If this method returns null
, the bundle considers that no transformation is needed.
The bundle also provides a CallbackTransformer
that can be used for faster implementations.
For instance handling an array can be done like this :
public function getModelTransformer(ParameterDefinition $definition): ?TransformerInterface { return new CallbackTransformer( function ($data) { if (!$data) { return null; } if (false !== ($unserialized = @unserialize($data))) { return $unserialized; } return $data; }, function ($data) { if (is_array($data)) { return serialize($data); } return $data; } ); }
