Multilingual Input Text Back office

Hi everybody,

 

I'm trying to do some Multilingual input Text BO on a Module. Is there any documentation to doing this ?

 

The Prestashop documentation miss this important and elementary part ! I was inspired by Editor Module but I failed since 1 week, and it seems to be very complicated. I suppose there is a  simple way.

 

Thank you for helping.

Hi Luzo. Here is the example :

<?php
if (!defined('_PS_VERSION_'))
	exit;
class DemoMulti extends Module
{
	public function __construct()
	{
		$this->name = 'demomulti';
		$this->tab = 'front_office_features';
		$this->version = '1.2.0';
		$this->author = 'test';
		$this->need_instance = 0;
		$this->ps_versions_compliancy = array('min' => '1.6', 'max' => _PS_VERSION_);
		$this->bootstrap = true;

		parent::__construct();

		$this->displayName = $this->l('DemoMulti');
		$this->description = $this->l('Multilanguage Test');
		$this->confirmUninstall = $this->l('Are you sure you want to uninstall?');
		$path = dirname(__FILE__);
		if (strpos(__FILE__, 'Module.php') !== false)
			$path .= '/../modules/'.$this->name;
			include_once $path.'/DemoMultiEditorClass.php';
	}

	public function install()
	{
		
		if (Shop::isFeatureActive())
		Shop::setContext(Shop::CONTEXT_ALL);
		if (!parent::install()
		|| !$this->registerHook('header')
		|| !$this->registerHook('rightColumn')

		}

		return $demomultieditorial->add();
	}
	
	
	public function uninstall()
	{
		if !parent::uninstall() 
						
		return false;
		
		$res = Db::getInstance()->execute('DROP TABLE IF EXISTS `'._DB_PREFIX_.'demomulti`');

		return true;
	}
	
	

	public function getContent()
	{
		$this->_html = '';
		$output = '';
		$errors = array();

		$helper = $this->renderEditorForm();
		
		$id_shop = (int)$this->context->shop->id;
		$lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
		$demomultieditorial = DemoMultiEditorClass::getByIdShop($id_shop);
			
		if (!$demomultieditorial) //if editorial do not exist for this shop => create a new example one
			$this->createExampleDemoMulti($id_shop);
		
		foreach ($this->fields_form['form']['input'] as $input) //fill all form fields

			else
			{
				Configuration::updateValue('demomulti_title', $demomulti_title);
				$output .= $this->displayConfirmation($this->l('Settings updated'));
			}
		}
	//Affichage 	
	return $output.$this->renderEditorForm();
	}
	
	public function renderEditorForm()
	{
	
	//Formulaire de l'éditeur
	$fields_form = array(
			'form' => array(
				'legend' => array(
					'title' => $this->l('Editor'),

			'input' => array
			(
				
				array(
					'type' => 'text',

				    'lang' => true,

					'desc' => $this->l('Appears along top of your homepage'),
				),
				
			),
				
				'submit' => array(

					'title' => $this->l('Save')
				)
			),
		);
		

		$helper = new HelperForm();
		$helper->show_toolbar = false;
		$helper->table = $this->table;
		$lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
		$helper->default_form_language = $lang->id;
		$helper->allow_employee_form_lang = Configuration::get('PS_BO_ALLOW_EMPLOYEE_FORM_LANG') ? Configuration::get('PS_BO_ALLOW_EMPLOYEE_FORM_LANG') : 0;
		$this->fields_form = array();
		$helper->identifier = $this->identifier;
		
		
		$languages = Language::getLanguages(false);
		foreach ($languages as $k => $language)
		$languages[$k]['is_default'] = (int)$language['id_lang'] == Configuration::get('PS_LANG_DEFAULT');
		$id_shop = (int)$this->context->shop->id;
		$demomultieditorial = DemoMultiEditorClass::getByIdShop($id_shop);
		
		$helper->currentIndex = $this->context->link->getAdminLink('AdminModules', false).
			'&configure='.$this->name.'&tab_module='.$this->tab.'&module_name='.$this->name;
		$helper->token = Tools::getAdminTokenLite('AdminModules');
		$helper->languages = $this->context->controller->getLanguages();
		$helper->default_form_language = (int)$this->context->language->id;

		return $helper->generateForm(array($fields_form));
	}

Here is the demomulti class

<?php

class DemoMultiEditorClass extends ObjectModel
{
	public $id;
	public $id_shop;
	public $demomulti_title;
	
	public static $definition = array(
		'table' => 'demomulti',
		'primary' => 'id_editorial',
		'multilang' => true,
		'fields' => array(
			'id_shop' => array('type' => self::TYPE_INT, 'validate' => 'isunsignedInt', 'required' => true),
			'demomulti_title' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName'),
		)
	);

	public static function getByIdShop($id_shop)
	{
		$id = Db::getInstance()->getValue('SELECT `id_editorial` FROM `'._DB_PREFIX_.'demomulti` WHERE `id_shop` ='.(int)$id_shop);
		return new DemoMultiEditorClass($id);
	}

	public function copyFromPost()
	{
		/* Classical fields */
		foreach ($_POST as $key => $value)
		{
			if (key_exists($key, $this) && $key != 'id_'.$this->table)
				$this->{$key} = $value;
		}

		/* Multilingual fields */
		if (count($this->fieldsValidateLang))
		{
			$languages = Language::getLanguages(false);
			foreach ($languages as $language)
			{
				foreach ($this->fieldsValidateLang as $field => $validation)
				{
					if (Tools::getIsset($field.'_'.(int)$language['id_lang']))
						$this->{$field}[(int)$language['id_lang']] = $_POST[$field.'_'.(int)$language['id_lang']];
				}
			}
		}
	}
}

I resolve it by copy/paste elements from Editorial Module. The postprocess class is very important.

 

Nevertheless, I find that the way to do input text multilinguage is too much complicated. It could be so easy to only put lang = true on helpers...

 

Thank you for reading.
