Processing fields for multi language forms

Recommended Posts

Hello,

I am building a dynamic frontend form from fields of a page, following Soma's great gist example.

The form is working fine, except for multi language values.

After this part of the code

$form->processInput($this->input->post)

when I loop over the form fields, I don't know how to access the multi language values of a field

foreach($form as $field) {
    // how to get multi lang values here
}

What I tried is not working

        foreach($form as $field) {
        	if($field->type instanceof FieldtypeLanguageInterface) {
        		foreach ($languages as $lang) {
        			$langval = $editpage->$field->getLanguageValue($lang);
        			$editpage->$field->setLanguageValue($lang, $langval);
        		}
        	} else {
	            $editpage->set($field->name, $field->value);
        	}
        } 

Actually the $field->type returns just "text" for a PageTitleLanguage field.

var_dumping the $field reveals that the language values are stored deep inside the object like

      'value1023' => string 'Testworkshop2' (length=13)
      'value1032' => string 'Testworkshop2 Englisch' (length=22)

So how would I access those other than pulling them directly from $this->input->post?

I think the problem is with $form->processInput($this->input->post) not taking into account multilanguage values.

get_class($editpage->title) returns: LanguagesPageFieldValue

But inside the foreach($form as $field) {...} a var_dump(get_class($field)) for the title field returns: InputfieldPageTitle

These are 2 different types of objects. I would expect to get a LanguagesPageFieldValue object where I can access multi language values. But sadly this is not the case.

Would be nice to have a method like processInputLanguage().

I have searched the code and the forum but cannot find a clue how to deal with multiliangugae fields in form processing.

Any help would be much appreciated.

The docs says:

$page->of(false); // outputFormatting must be OFF

https://processwire.com/api/multi-language-support/multi-language-fields/#getting-and-setting

"The value of a multi-language or language-alternate field is affected by the "outputFormatting" setting of a page. On the front-end of your site, outputFormatting is always turned on, unless you've turned it off."

"When outputFormatting is ON, the value of a multi-language field is a string (as it shows in most examples on this page). That string reflects the value from the current user's language. If the value is blank in the current user's language, the value from the default language will be there instead.

However, when outputFormatting is OFF, the value of a multi-language field (like $page->body) will instead return an object of type LanguagesPageFieldValue, rather than a string. That object contains all of the translations available for the given field."
 

I'm not sure that this solves anything, I'm just guessing. Sorry if I'm mistaken.

Thank you for taking the time to look into this.

Unfortunatley this doesn't apply to my situation because I already switch off output formatting right before the foreach loop

        $editpage->setOutputFormatting(false);
        foreach($form as $field) {
            // here is where I need to get the multi language values
            $editpage->set($field->name, $field->value);
        }

Raising this from the dead, but setLanguageValue() and getLanguageValue() are pretty useful for those kind of things.

From code/Page.php
 
 * Methods added by LanguageSupport.module (not installed by default) 
 * ------------------------------------------------------------------
 * @method Page setLanguageValue($language, $fieldName, $value) Set value for field in language (requires LanguageSupport module). $language may be ID, language name or Language object.
 * @method Page getLanguageValue($language, $fieldName) Get value for field in language (requires LanguageSupport module). $language may be ID, language name or Language object.

      Hi there, 

      I feel like I have another rather stupid question, but I am stucked in a problem. 
      I wrote a small module, which makes use of the multi-language option.

      The inputfield code looks like this:
      $donationText = $this->modules->InputfieldCKEditor; $donationText->useLanguages = true; $donationText->name = 'donationtext'; $donationText->label = 'Donation CTA Text'; $donationText->value = $this->donationtext; $donationText->required = true; $wrapper->add($donationText); My simplified render method in the module looks like this:
      public function renderDonationCTA(){ echo $this->donationtext; } However, when I call this method in my template code only the default language gets outputted.
      What did I miss or what can I do, in order to output the inserted text in the "right" language?

      A minor gripe but one that trips me up every time.
      When there's naming error on a field, ALL the field values are erased and I have to setup everything again. IE name, type, label and descriptions details and sometimes notes.
      Would be really helpful if ProcessWire didn't zap all the values but just cleared the illegal field name.

      I have been following @bernhard's great tutorial on creating a Dashboard and everything has very easy to understand so far. However, I need to add a select field that a template is using (so users can create a new page from the dashboard), but I am really at a complete lost on how to achieve this. I have been googling, but can't really find anything on the matter.
      $field = $this->modules->get('InputfieldSelect'); $field->name = "Select Manufacturer"; $field->findPagesSelector = "template=basic-page"; //not needed for select field $field->labelFieldName = "title"; $field->name = "Manufacturer Select"; $field->columnWidth = 34; $fieldset->add($field); I have the above code, which was originally an InputfieldPage, but since this is an options field, I have changed it. Has anyone actually gotten a select from a template (and its' values) in a module?

      How do you include fields in Twig templates?
      Tried using {% $page->Title %}, but that creates an error.
      Thanks

      Hello fellow Process wire Developers!
      Today i have encountered an issue using the repeater where I can't find out how to solve it therefore i am asking for help.
      To be specific, I am trying to get the "file" field working properly in the repeater but i couldn't find a way on how to assign a property of a field that is being used by the repeater.
      download_pdf is the name of the field that i want to access properties from.
      What i wished i could do was something like $download->download_pdf.size or $download->download_pdf->name, something like that but obviously these didn't work
      Hope there is a solution and thanks in advance!
      Best wishes,
      Livius
