README

This utility bundle offers functionality for backend editor's to translate arbitrary fields of any table-driven data container in the Contao CMS.

Features

• define which fields of which data containers should be translatable
• adds a button to the backend palette for switching into translation mode
• content elements: optionally add a select field to the backend palette in order to display the corresponding content element only for the selected language

Impressions

The button for editing the languages (right) and the button for showing certain content elements only for the selected language (left, for tl_content only)

Editors can specify which of the fields should be translated for which languages

Use case

The use case for this bundle is to have an automatic and structured process for adding translatable fields to a data container. Also, you get a nice and editor-friendly way to edit translations in the backend ;-)

What doesn't the bundle do?

Currently for most data containers this bundle is a utility bundle for just bringing a nice and editor-friendly way to edit translations in the backend. It's up to you how to use the fields.

Besides tl_content there's no out-of-the-box support for contao's frontend modules!

But you can of course use the created fields in your templates (if the modules passes the data there).

How does it work?

The bundle works quite simply: it looks into your project's <project_dir>/config/config.yml and based on that adds the fields defined here as translatable fields.

Example: Imagine the following config.yml (position is the field representing the job of the member in the company):

huh_multilingual_fields:
  fallback_language: de
  languages:
    - en
  data_containers:
    tl_member:
      fields:
        - { name: position }

This would end up in your DCA being automatically modified the following way:

// ...
[
    // the original position field is nearly unchanged -> only some meta field links are set in eval
    'position' => [
        'exclude'   => true,
        'search'    => true,
        'inputType' => 'text',
        'eval'      => [
            'maxlength' => 128,
            'tl_class' => 'w50',
            'mandatory' => true,
            'isTranslatedField' => true,
            'translationConfig' => [
                'en' => [
                    'field' => 'en_position',
                    'selector' => 'en_translate_position'
]               ]
            ]
         ],
        'sql'       => "varchar(128) NOT NULL default ''"
    ],
    // automatically created: the selector field and the translation field
    // the selector field (subpalette and selector is also set)
    'en_translate_position' => [
        'label'     => ['Translate (English)', 'Click this option in order to translate the field for the given language.'],
        'exclude'   => true,
        'inputType' => 'checkbox',
        'eval'      => [
            'tl_class' => 'w50',
            'submitOnChange' => true,
            'translationField' => 'en_position',
            'translatedField' => 'position'
        ],
        'sql'       => "char(1) NOT NULL default ''",
    ],
    // the translation field
    'en_position' => [
        'label'     => ['Position (English)', '<the description as given>'], // generated automatically out of the label of the "position" field
        'exclude'   => true,
        'search'    => true,
        'inputType' => 'text',
        'eval'      => [
            'maxlength' => 128,
            'tl_class' => 'w50',
            'mandatory' => true,
            'translatedField' => 'position',
            'translationSelectorField' => 'en_translate_position'
         ],
        'sql'       => "varchar(128) NOT NULL default ''"
    ]
]

Installation & configuration

1. Run composer require heimrichhannot/contao-multilingual-fields-bundle.
2. Create the file <project_dir>/config/config.yml if not already existing and specify your translatable fields:

   huh_multilingual_fields:
     fallback_language: de
     content_language_select: # add a select field to content element palettes for displaying elements only for the specified language
       enabled: true # default: false
       types: # if not set, the select field is added to all tl_content types
         - text
     languages:
       - en
     data_containers:
       tl_member:
         sql_condition: tl_member.firstname LIKE ? # optional; activate the functionality only for some entities
         sql_condition_values:
           - "%%john%%" # be careful about escaping; in yaml the reserved character "%" can't be in first place and need to be be escaped
         fields:
           - { name: alias, is_alias_field: true, alias_base_field: lastname }
           - { name: lastname }
           - { name: position }

3. Clear the project's cache (<project_dir>/var/cache).
4. Update the database. The new fields should be created now.

Insert tags

The following new insert tags are available. These take into account the translated jumpTo url and alias.
