README

A visual component for applications using the Nette framework, allowing them to work easily and anywhere in a unified way with flash messages.

Requirements

• PHP >= 8.5

Installation

The best way to install interitty/flash-message-control is using Composer:

composer require interitty/flash-message-control

Register in config.neon

Then register the component in the Nette config file:

# app/config/config.neon
services:
    FlashMessageControlFactory:
        implement: Interitty\FlashMessageControl\FlashMessageControlFactoryInterface

Register in Presenter or Control

Any component or presenter that needs to work with a flash messages can then add this component.

<?php

declare(strict_types=1);

namespace App\Presenters;

use Interitty\FlashMessageControl\FlashMessageControl;
use Interitty\FlashMessageControl\FlashMessageControlFactoryInterface;
use Interitty\FlashMessageControl\FlashMessageControlHelperTrait;
use Nette\Application\UI\Presenter;

abstract class BasePresenter extends Presenter
{
    use FlashMessageControlHelperTrait;

    protected FlashMessageControlFactoryInterface $flashMessageControlFactory;

    public function injectFlashMessageControlFactory(FlashMessageControlFactoryInterface $flashMessageControlFactory): void
    {
        $this->flashMessageControlFactory = $flashMessageControlFactory;
    }

    protected function createComponentFlashMessage(string $name = 'flashMessage'): FlashMessageControl
    {
        $component = $this->flashMessageControlFactory->create($this, $name);
        return $component;
    }
}

ℹ️ Simplified registration

If the extension interitty/component-model is used in the application, the registration in Presenter is much easier.

><?php

>declare(strict_types=1);

>namespace App\Presenters;

>use Interitty\ComponentModel\ComponentLocatorTrait;
>use Interitty\FlashMessageControl\FlashMessageControlHelperTrait;
>use Nette\Application\UI\Presenter;

>abstract class BasePresenter extends Presenter
>{
   use ComponentLocatorTrait;
   use FlashMessageControlHelperTrait;
>}

Register in latte template

Once the component is registered, you can easily render it within the latte template.

{control flashMessage}

Usage

Thanks to the used FlashMessageControlHelperTrait auxiliary functions are available for adding a flash message of the appropriate type.

<?php

declare(strict_types=1);

namespace App\Presenters;

use Interitty\FlashMessageControl\FlashMessageControlFactory;
use Interitty\FlashMessageControl\FlashMessageControlHelperTrait;
use Nette\Application\UI\Presenter;

abstract class BasePresenter extends Presenter
{
    use FlashMessageControlHelperTrait;

    public function renderDefault()
    {
        $this->flashMessageSuccess('The :control was succesfully registered.', ['control' => FlashMessageControlFactory::class]);
    }
}

It is also possible to use the otherwise standard flashMessage method, which has been extended with a third parameter to pass additional parameters that will be inserted after translation in place of their :placeholders.

All these methods return an Interitty\FlashMessageControl\FlashMessage object that has a fluent interface for possible further settings.

<?php

declare(strict_types=1);

namespace App\Presenters;

use Interitty\FlashMessageControl\FlashMessage;
use Interitty\FlashMessageControl\FlashMessageControlHelperTrait;
use Nette\Application\UI\Presenter;

abstract class BasePresenter extends Presenter
{
    use FlashMessageControlHelperTrait;

    public function renderDefault()
    {
        $this->flashMessage()
            ->setMessage('The Interitty flash messages are :status!')
            ->setType(FlashMessage::TYPE_SUCCESS)
            ->addData('status', 'awesome');
    }
}

Custom template

By default, the component uses a template that renders individual flash messages as separate div blocks with the appropriate css class settings.

However, it can certainly be useful to set a custom rendering method. This can easily be done by setting the path to the custom template, for example directly in the Nette config file.

# app/config/config.neon
services:
    FlashMessageControlFactory:
        implement: Interitty\FlashMessageControl\FlashMessageControlFactoryInterface
        setup:
            - setTemplateFile(%appDir%/Controls/FlashMessage/FlashMessageControlCustom.latte)
