README

Translation Fields is a library for Contao developers to get nice translation fields in the Contao Open Source CMS. Every translation field gets a language flag and can be translated by changing the flag to another language. The translations will be saved in the table tl_translation_fields and a key from this table will be stored in the field self.

Installation

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require craffft/translation-fields-bundle "dev-master"

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new Craffft\TranslationFieldsBundle\CraffftTranslationFieldsBundle(),
        );

        // ...
    }

    // ...
}

Input types

There are three input types that you can use in the back end.

  • TranslationTextField (the same as input type text)
  • TranslationTextArea (the same as input type textarea)
  • TranslationInputType (the same as input type inputType)

How to define a field in the DCA

To use the translation fields, you have to do the following changes in your DCA code.

  • Add an index to your field
  • Change the input type
  • Change the sql to int(10)
  • Add a relation to your field

Each field uses different settings. You can see this in the following codes.

Examples

Text Field

The original field:

$GLOBALS['TL_DCA']['tl_mytable']['fields']['myfield'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_mytable']['myfield'],
    'exclude'                 => true,
    'inputType'               => 'text',
    'eval'                    => array('maxlength'=>255),
    'sql'                     => "varchar(255) NOT NULL default ''"
);

The field after the changes:

$GLOBALS['TL_DCA']['tl_mytable']['config']['sql']['keys']['myfield'] = 'index';
$GLOBALS['TL_DCA']['tl_mytable']['fields']['myfield'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_mytable']['myfield'],
    'exclude'                 => true,
    'inputType'               => 'TranslationTextField',
    'eval'                    => array('maxlength'=>255),
    'sql'                     => "int(10) unsigned NOT NULL default '0'",
    'relation'                => array('type'=>'hasOne', 'load'=>'lazy')
);

Textarea Field

The original field:

$GLOBALS['TL_DCA']['tl_mytable']['fields']['myfield'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_mytable']['myfield'],
    'exclude'                 => true,
    'inputType'               => 'textarea',
    'eval'                    => array('rte'=>'tinyFlash', 'tl_class'=>'long'),
    'sql'                     => "text NULL"
);

The field after the changes:

$GLOBALS['TL_DCA']['tl_mytable']['config']['sql']['keys']['myfield'] = 'index';
$GLOBALS['TL_DCA']['tl_mytable']['fields']['myfield'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_mytable']['myfield'],
    'exclude'                 => true,
    'inputType'               => 'TranslationTextArea',
    'eval'                    => array('rte'=>'tinyFlash', 'tl_class'=>'long'),
    'sql'                     => "int(10) unsigned NOT NULL default '0'",
    'relation'                => array('type'=>'hasOne', 'load'=>'lazy')
);

Input Unit Field

The original field:

$GLOBALS['TL_DCA']['tl_mytable']['fields']['myfield'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_mytable']['myfield'],
    'exclude'                 => true,
    'inputType'               => 'inputUnit',
    'options'                 => array('h1', 'h2', 'h3', 'h4', 'h5', 'h6'),
    'eval'                    => array('maxlength'=>200, 'tl_class'=>'w50'),
    'sql'                     => "blob NULL"
);

The field after the changes:

$GLOBALS['TL_DCA']['tl_mytable']['config']['sql']['keys']['myfield'] = 'index';
$GLOBALS['TL_DCA']['tl_mytable']['fields']['myfield'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_mytable']['myfield'],
    'exclude'                 => true,
    'inputType'               => 'TranslationInputUnit',
    'options'                 => array('h1', 'h2', 'h3', 'h4', 'h5', 'h6'),
    'eval'                    => array('maxlength'=>200, 'tl_class'=>'w50'),
    'sql'                     => "blob NULL",
    'relation'                => array('type'=>'hasOne', 'load'=>'lazy')
);

How to translate the field values

To translate the key from your current field, you can use the following methods

Translate value

Translates the field key to the translation value in the current language.

$intId = '1485'; // Example value

/* @var $objTranslator Translator */
$objTranslator = \System::getContainer()->get('craffft.translation_fields.service.translator');

$strTranslated = $objTranslator->translateValue($intId);

echo $strTranslated; // Returns e.g. "Hi there!"

Optional you can add a force language to the translateValue method.

$intId = '1485'; // Example value
$strForceLanguage = 'de';

/* @var $objTranslator Translator */
$objTranslator = \System::getContainer()->get('craffft.translation_fields.service.translator');

$strTranslated = $objTranslator->translateValue($intId, $strForceLanguage);

echo $strTranslated; // Returns e.g. "Hallo zusammen!"

Translate DataContainer object

Translates all translation field values in the data container object to a translated value.

$objDC->exampleValue = '1485'; // Example value

/* @var $objTranslator Translator */
$objTranslator = \System::getContainer()->get('craffft.translation_fields.service.translator');

$objDC = $objTranslator->translateDCObject($objDC);

echo $objDC->exampleValue; // Returns e.g. "Hi there!"

Translate DCA

Translates all translation field values in the data container array to a translated value.

$arrDC['exampleValue'] = '1485'; // Example value

/* @var $objTranslator Translator */
$objTranslator = \System::getContainer()->get('craffft.translation_fields.service.translator');

$arrDC = $objTranslator->translateDCArray($arrDC, $strTable);

echo $arrDC['exampleValue']; // Returns e.g. "Hi there!"

Runonce

If you already have content in your application fields, you have to ensure that translation fields doesn't remove your content data. Therefore you have to create a runonce which inserts the current values into the tl_translation_fields table and associate the key with the field.

You can do this like in the following code:

class MyApplicationRunconce extends \Controller
{
    public function run()
    {
        // Code ...

        \Craffft\TranslationFieldsBundle\Util\Updater::convertTranslationField('tl_my_table_name', 'my_field_name');

        // Code ...
    }

    // Code ...
}

E.g. you can have a look at the runconce.php from my extension Photoalbums2: https://github.com/Craffft/contao-photoalbums2/blob/master/config/runonce.php
