The following document holds information about the installation of the TYPO3 dfgviewer extension.
The current release 5.x will only work with TYPO3 8.7 LTS or 9.5 LTS.
The extension is based on Kitodo.Presentation (dlf). Before you can start to use the DFG Viewer (dfgviewer) in your TYPO3 installation, you have to install both extensions. The installation in only possible by composer. Kitodo.presentation will be installed and configured automatically.
You need a webserver stack with Apache2 or Ngnix, PHP >= 7.3 and MySQL / MariaDB. Debian 10 (buster) is known to work with Kitodo.Presentation 3.1 and DFG-Viewer 5.0.
We recommend at least:
- CPU: 1
- Memory: 2 GB
- Disk: 20 GB
Install a fresh TYPO3 8.7 LTS¶
To install a fresh TYPO3 (8.7 or 9.5) system, try the following installation procedure with composer:
# Assuming the following settings: # * the installation directory is /var/www/dfgviewer # * the Apache DocumentRoot is /var/www/dfgviewer/public # * Apache is running as user www-data with group www-data # * execution of all following commands as user www-data www-data@localhost:~/> cd /var/www/ # remove /var/www/dfgviewer if it already exist www-data@localhost:/var/www> rm -r dfgviewer/ # load full TYPO3 via composer www-data@localhost:/var/www> composer create-project typo3/cms-base-distribution:^9.5 dfgviewer # If you want to use TYPO3 8 LTS then use this command: "composer create-project typo3/cms-base-distribution:^8.7 dfgviewer" # create FIRST_INSTALL file www-data@localhost:/var/www> cd dfgviewer/ www-data@localhost:/var/www/dfgviewer> touch public/FIRST_INSTALL
Now you can switch to the web-based installation of TYPO3 in your browser. Just follow the 4 steps. You need your MySQL/MariaDB credentials of course.:
# continue with installation via webbrowser http://example.com/ 1. Step: "System environement" 2. Step: "Database connection" 3. Step: "Select database" --> Best is to create the database and user before. 4. Step: "Create admin user account" 5. Step: "Installation done!" --> Select "Do nothing, just get me to the Backend." # Test your backend login: http://example.com/typo3/
The DFG-Viewer extension assumes the default language is German (&L=0). An additionial “website-language” English (&L=1) will be created automatically on installing the DFG-Viewer extension. This is only relevant for localization of the metadata and structures labels.
Recommended Steps after Installation¶
- Go to the language module and install “German” as backend language.
- [optional] Change the backend language in your user settings to German.
- Go to the Install Tool –> All Configurations and change the default settings of pageNotFoundOnCHashError to ‘0’.
Your typo3conf/LocalConfiguration.php should contain this:
'FE' => [ 'pageNotFoundOnCHashError' => '0', ],
Now you have a working TYPO3 8.7 or 9.5 LTS installation and you can continue with composer to install DFG-Viewer extension.
If you are using e.g. TYPO3 8.7 and Debian 10 with MariaDB 10.3 you have to force an update of Doctrine/Dbal. This is due to a missing feature / bug in doctring/dbal 2.5.13. TYPO3 8.7 did not changed the dependancies for doctrine/dbal.
This way is working for the DFG-Viewer:
www-data@localhost:/var/www/dfgviewer> composer require doctrine/dbal 2.5.13 # in composer.json, change the following line: # "doctrine/dbal": "2.7.2 as 2.5.13" www-data@localhost:/var/www/dfgviewer> composer update doctrine/dbal --with-dependencies
Install DFG-Viewer and Kitodo.Presentation via Composer¶
composer require kitodo/presentation:^3.1 composer require slub/dfgviewer:^5.0
This will install the DFG-Viewer 5.x extension and Kitodo.Presentation 3.1 from Packagist.
Install the Extension via extension manager or CLI:
www-data@localhost:/var/www/dfgviewer> ./vendor/bin/typo3 extensionmanager:extension:install dlf www-data@localhost:/var/www/dfgviewer> ./vendor/bin/typo3 extensionmanager:extension:install dfgviewer
During the installation, three pages will be created: a root page, the “Kitodo Configuration” folder and the viewer itself.
Configure DFG-Viewer and Kitodo.Presentation¶
The DFG-Viewer is almost configured. Only the Page-ID-constants have to be checked and adjusted. Go to the template module and use the constant editor to fit your installation.
Now your installation should work. You can test this with the following url (replace host and id with the parameters of your installation):
To pass a document to the viewer, use the tx_dlf[id] GET parameter. Don’t forget to urlencode the value.:
You should use the following configuration in typo3conf/LocalConfiguration.php:
'FE' => [ 'pageNotFoundOnCHashError' => '0', 'pageNotFound_handling' => '', ],
If you want to reinstall the DFG-Viewer extension, the metadata and structure records won’t be created a second time. To force this, you have to delete the entry in table ‘sys_references’.
