README

This bundle offers functionality concerning terminal42/contao-DC_Multilingual for the Contao CMS.

Features

• adds multilanguage support for tl_content
• adds shortcut functions for rapidly activating DC_Multilingual support for a given DCA
• adds multilanguage support for madeyourday/contao-rocksolid-custom-elements
• adds insert tags for generating multilingual event, news or faq urls
• caution: overrides the id handling of DC_Multilingual v4+ to the v3 behavior (the record with the joined translation has its id set to the id of the translation record)

Installation

1. Install via composer: composer require heimrichhannot/contao-dc-multilingual-utils-bundle.
2. Activate DC_Multilingual support for tl_content (not optional):

/**
 * @Hook("loadDataContainer")
 */
class LoadDataContainerListener
{
    private DcMultilingualUtil $multilingualUtil;

    public function __invoke(string $table): void
    {
        if ('tl_content' === $table) {
            $this->multilingualUtil->addDcMultilingualSupport(
                $table, ['de', 'en', 'pl'], 'de', [ 'text', 'rsce_data' ] 
            );
        }
    }
}

Technical details

Insert tags

The following new tags are available:

Activate DC_Multilingual rapidly using the shortcut functions

Simply call the following code:

/**
 * @Hook("loadDataContainer")
 */
class LoadDataContainerListener
{
    private DcMultilingualUtil $multilingualUtil;

    public function __invoke(string $table): void
    {
        if ('tl_content' === $table) {
            $this->multilingualUtil->addDcMultilingualSupport(
                $table, // Table name
                ['de', 'en', 'pl'], // Supported languages
                'de', // Fallback language
                [ // the translatable fields
                    'text', // add fields here...
                    'rsce_data' // add this if you have rocksolid custom elements (tl_content only)
                ],
                [ // options
                    'langColumnName', // the language field in the dca's records (you have a record for every language and this column holds which one it is)
                    'langPid', // this field holds the parent record of every translated record
                ]
            );
            break;
        }
    }
}

Notes on overridden classes

For generating content elements which respect the multilanguage records created using DC_Multilingual in the backend, it's necessary to override the ContentModel, because Contao calls the core's ContentModel directly in Controller:

$objRow = ContentModel::findByPk($intId);

But for getting Contao to output the translated Elements, we need to use our own ContentModel inheriting from the class Terminal42\DcMultilingualBundle\Model\Multilingual/Multilingual.
