Multilanguage module

[Juhas0]

Hi, I am creating my first module. I want it to be multilingual. Some presta modules on their configuration page give possibility to enter text for different languages (they have for example some kind of button to choose current language near textfield).

 

So I tried to do that, but I didn't manage. I know how to create simple form using HelperForm. But I don't have any idea how to add to this form multi language functionality. Can anybody help?

For add multialnguage text you must change your every content from format 'text' to $this->l('text', 'module_name).

After that you'll be able to translate your text on back-office.

You can use the following code to add a multi-language field in the HelperForm class:

 

array(
                       'type' => 'textarea',
                       'label' => $this->l('Enter small note'),
                       'name' => 'age_verification_note',
                       'hint' => $this->l('Enter the small note to be display at the top'),
                       'desc' => $this->l('Only 120 character allowed.'),
                       'class' => 'optn_general',
                       'lang' => true,
                       'required' => true,
                       'maxlength' => 120,
                       'cols' => 100,
                   )

Hmm, I hoped it would be that simple

I hoped it would be that simple. But it isn't. When I add this attribute: 'lang' => true, my textarea becomes invisible. This is my input definition for this field:

array(
	'type' => 'textarea',
	'class' => 'rte autoload_rte rte',
	'label' => $this->l('Description'),
	'name' => 'html',
        'lang' => true,
	'required' => true
),

OK, so I noticed that giving 'lang' attribute is not enought. I found out that I have to do some other things:

 

- get available languages, set default language and add them to HelperForm:

//this is not optimal, but it shows how to do this
$languages = Language::getLanguages(false);
foreach ($languages as $k => $language)
	$languages[$k]['is_default'] = (int)$language['id_lang'] == Configuration::get('PS_LANG_DEFAULT');
		
		
$helper->languages = $languages;

But still there is something wrong. When I open this page I get warnings:

 

Notice line 775 in file www\prestashop\tools\smarty\sysplugins\smarty_internal_templatebase.php(157) : eval()'d code
[8] Uninitialized string offset: 1

Notice line 775 in file www\prestashop\tools\smarty\sysplugins\smarty_internal_templatebase.php(157) : eval()'d code
[8] Uninitialized string offset: 2

 

And I just can't figure it out. Could anyone help? Please, it's killing me.

 

[EDIT]

 

Eureka! At last! Field that is to be multilingual must be filled with content for every language. And this field is an array of strings with keys representing language id. So one should do something like that:

foreach ($helper->languages as $language)
{
	$helper->fields_value['html'][$language['id_lang']] = "";
}

Of course this is bad example, because 'html' field will always have empty string. But I didn't figure it out yet, how to get proper values from existing object.

Check some of the standard modules e.g. ps_customtext
