Introduction

What does it do?

This extension provides several features to show an environment indicator in the TYPO3 frontend and backend.

Note

These environment indicators are mainly for development purposes (e.g. distinguishing between different test systems) and will not show in production environments.

Features

Frontend Hint: Adds an informative hint to the frontend showing the website title and the current application context.

Backend toolbar: item: Adds an informative item with the current application context to the backend toolbar.

Modified favicon: Modify the favicon for frontend and backend based on the original favicon, the current application context and your configuration.

Support

There are several ways to get support for this extension:

GitHub: https://github.com/jackd248/typo3-environment-indicator/issues

License

This extension is licensed under GNU General Public License 2.0 (or later).

Installation

Requirements

PHP 8.1 - 8.4
TYPO3 11.5 LTS - 13.4 LTS
ImageDriver: GD, Imagick or libvips

Installation

Require the extension via Composer (recommended):

composer require konradmichalik/typo3-environment-indicator

Or download it from the TYPO3 extension repository.

Configuration

Include the static TypoScript template "Environment Indicator" or directly import it in your sitepackage (only necessary for the frontend Hint):

Configuration/TypoScript/setup.typoscript

@import 'EXT:typo3_environment_indicator/Configuration/TypoScript/setup.typoscript'

Note

Only the following favicon image formats are supported*: https://image.intervention.io/v3/introduction/formats

Due to the wide distribution of .ico files, these images are also supported.

Configuration

The extension is ready to use without any further setup.

You can also adapt the extension to your needs, switch single features on and off and influence the presentation of the indicators.

Learn what configuration options are available on the following pages:

Extension configuration

Go to Admin Tools > Settings > Extension Configuration

Frontend Hint

The frontend hint will show the current application context information and the website title as clickable note in the upper right corner.

You can adjust the color of the hint in your ext_localconf.php:

ext_localconf.php

\KonradMichalik\Typo3EnvironmentIndicator\Utility\ConfigurationUtility::configByContext(
    applicationContext: 'Development',
    frontendHintConfiguration: [
        'color' => '#bd593a',
    ],
);

position (string): The position of the frontend hint. Default is top left. Possible values are bottom left,

bottom right, top left, top right.

Backend toolbar item

The backend toolbar item will show the current project version and application context.

You can adjust the color of the toolbar item in your ext_localconf.php:

ext_localconf.php

\KonradMichalik\Typo3EnvironmentIndicator\Utility\ConfigurationUtility::configByContext(
    applicationContext: 'Development',
    backendToolbarConfiguration: [
        'color' => '#bd593a',
    ]
);

Additional optional configuration keys:

text (string): The text of the toolbar item. Default is the application context.

Favicon

The favicon of the frontend or backend context will be modified regarding the application context and the associated configuration.

Favicon Example

depth: 2

Frontend

For the frontend, the original favicon will either be fetched from the typoscript configuration page.shortcutIcon (see typoscript reference) or can be handled by your own fluid template via the FaviconViewHelper:

Custom fluid template

<html xmlns:env="http://typo3.org/ns/KonradMichalik/Typo3EnvironmentIndicator/ViewHelpers"
    data-namespace-typo3-fluid="true">

{f:uri.resource(path:'EXT:your_extension/Resources/Public/Favicon/favicon.png') -> env:favicon()}
{env:favicon(favicon:'EXT:your_extension/Resources/Public/Favicon/favicon.png')}

FaviconViewHelper

Backend

For the backend, the favicon will be fetched by the extension configuration of $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['backend']['backendFavicon'].

Favicon Examples

Modifiers

The favicon modification configuration can be found in $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['typo3_environment_indicator'].

Add a configured favicon modifier to the desired application context (e.g. Testing) in your ext_localconf.php:

ext_localconf.php

\KonradMichalik\Typo3EnvironmentIndicator\Utility\ConfigurationUtility::configByContext(
    applicationContext: 'Testing',
    faviconModifierConfiguration: [
        \KonradMichalik\Typo3EnvironmentIndicator\Image\TextModifier::class =>
        [
            'text' => 'TEST',
            'color' => '#f39c12',
            'stroke' => [
                'color' => '#ffffff',
                'width' => 3,
            ],
        ]
    ],
);

The modifiers will be executed one after the other. You can combine them if you want.

Note

If you want to specify the frontend or backend favicon separately, you can add the another parameter for the request context faviconModifierFrontendConfiguration or faviconModifierBackendConfiguration to the configByContext() method.

The following modifier classes are available:

TextModifier

This is the default modifier if no own configuration is set.

            'stroke' => [
                'color' => '#ffffff',
                'width' => 3,
            ],
        ]
    ],

ColorizeModifier

Note

If you want to modify the image to your own need, implement a custom modifier class and add it to the configuration.

Developer corner

Some kinds of the environment indicators are configurable or can be extended with custom implementations. This section provides an insight into which development options are available and how these can be integrated into the generation process.

Custom modifiers

The predefined modifiers are not enough for your use case? No problem! You can easily write your own.

Implement your own image modifier by extending the AbstractModifier class and implementing the ModifierInterface method.

Classes/Image/CustomModifier.php

<?php

namespace Vendor\YourExt\Image;

use Intervention\Image\Geometry\Factories\RectangleFactory;
use Intervention\Image\Interfaces\ImageInterface;

class CustomModifier extends AbstractModifier implements ModifierInterface {

    public function modify(ImageInterface &$image): void
    {
        // Modify the image
    }

    public function getRequiredConfigurationKeys(): array
    {
        // Return the required configuration keys
    }
}

See the Intervention Image documentation for more information about image manipulation.

Note

Having fun with colorful favicons? Use the ColorUtility::getColoredString() function as color entry in your modifier configuration to generate a color based on a string (default is the $GLOBALS['TYPO3_CONF_VARS']['SYS']['sitename']).

Configuration Utility

Generally the whole configuration can be found in $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['typo3_environment_indicator']. You can/should use the ConfigurationUtility::configByContext() to easily add necessary configuration for the environment indicator.

ext_localconf.php

// Add a colorized favicon modifier, add a colorful backend toolbar item and unset the frontend hint for the Development context
\KonradMichalik\Typo3EnvironmentIndicator\Utility\ConfigurationUtility::configByContext(
    applicationContext: 'Development',
    faviconModifierConfiguration: [
        \KonradMichalik\Typo3EnvironmentIndicator\Image\ColorizeModifier::class =>
        [
            'color' => '#039BE5',
        ]
    ],
    faviconModifierFrontendConfiguration: [
        \KonradMichalik\Typo3EnvironmentIndicator\Image\ColorizeModifier::class =>
        [
            'opacity' => 0.5 // Change just the opacity for the frontend favicon configuration
        ]
    ],
    frontendHintConfiguration: null, // Unset frontend hint for Development context
    backendToolbarConfiguration: [
        'color' => '#039BE5',
    ]
);
