get field specific language

[ÉtienneOz]

Hi,

I'm facing an issue with no idea to solve it, even after a look on the forum and search engines.

I want to output each language available for a specific field on my page but without using a foreach loop. When I try to use setOutputFormatting() function it shows this error message:

Error: Uncaught Error: Call to a member function setOutputFormatting() on boolean [...]

For some reason I can't use a foreach function, I'm calling each page with a conditionnal incrementation of $i ($article[$i]). It seems the issue come from here but is there a way to bypass this?

Tell me if you need more information,

Thanks in advance,

Étienne

Well, a little code would be useful. Is this in a regular frontend template, or inside your custom module? WIthout seeing some code, it's hard to say why you're not able to do a loop...

Yes sorry for the lake of information.

It is in a frontend template but I use a recursive function with an incrementation of a int variable so I store my subpages in an array using

$article = $page->children;

and call them using

$article[$i];

 

Here is an except of the code:

  $parts = $page->children('template=parts');
  foreach ($parts as $i => $part) {
?>
  <section id="<?= $part->id ?>" class="part lvl2 <?php echo ($i%2 == 0 ? 'even' : 'odd'); ?>">
    <h1><?= $title ?></h1>
    <?php
      $lvl = 3;
      $i = 0;
      recursionLvl3($lvl, $i, $part, $article, $permalink);
    ?>
  </section>

<?php
  }
?>

The recursive function:

  function recursionLvl3($lvl, $i, $part, $article, $permalink){

    echo '<section class="lvl3">
            <article class="lvl4 '; echo ($permalink == $article[$i]->name ?  (strlen($article[$i]->title) > 0 ? 'big"' : '') : '"'); echo ($article[$i]->name ? ' id="' . $article[$i]->name . '"' : '"'); echo'>';
              createArticle($article[$i]);
    echo '  </article>
          </section> <!-- lvl3 -->';
    $i++;
    echo '<section class="lvl3">';
    echo '  <section class="lvl4">';
    echo  '   <article class="lvl5 '; echo ($permalink == $article[$i]->name ?  (strlen($article[$i]->title) > 0 ? 'big"' : '') : '"'); echo ($article[$i]->name ? ' id="' . $article[$i]->name . '"' : '"'); echo '>';
                createArticle($article[$i]);
    echo '    </article>';
    echo '  </section> <!-- lvl4 -->';
    $i++;
    echo '  <section class="lvl4">';
    $lvl++;
    if ($lvl > 0 && $i < count($part->children)) {
      recursionLvl3($lvl, $i, $part,  $article, $permalink);
    }
    echo '  </section> <!-- lvl4 -->';

    echo '</section> <!-- lvl3 -->';
  }

and createArticle function:

  function createArticle($el){


    //
    // $el->setOutputFormatting(false);
    // $title = $el->title->getLanguageValue('default');
    // $titleFR = ($el->title->getLanguageValue('fr') ? $el->title->getLanguageValue('fr') : $title);
    // $titleNL = ($el->title->getLanguageValue('nl') ? $el->title->getLanguageValue('nl') : $title);

    echo '  <div class="close closeArticle"><span>×</span></div>';
    echo ($el->title ? '<h2>'. $el->title .'</h2>' : '');
    echo ($el->sous_titre ? '<h3>'. $el->sous_titre .'</h3>' : '');
    echo '<div class="dates">';
      echo ($el->date_debut ? '<h4 class="dateDebut"><span></span> ' . $el->date_debut . ' </h4>' : '');
      echo ($el->date_fin ? '<h4 class="dateFin"> <span>  ⤑  </span> ' . $el->date_fin . '</h4><br>' : '');
      echo ($el->vernissage ? '<h4 class="vernissage"> <span>vernissage&thinsp;: </span>' . $el->vernissage . '</h4>' : '');
    echo '</div>';
    echo ($el->images ? '<img src="' . $el->images->first()->url . '" alt="" />' : '' );
    echo '<div class="content">';
      echo ($el->contenu ? $el->contenu : '' );
    echo '</div>';
    echo ($el->en_savoir_plus ? '<p class="savoirPlus">' : '' );
      echo ($el->en_savoir_plus ? '<a href="' . $el->en_savoir_plus . '" target="_blank">En savoir plus</a>' : '' );
    echo ($el->en_savoir_plus ? '</p>' : '' );
  }

The commented lines are those which cause an issue.

 

Thank you,

This worked for me. See the changes in getLanguageValue();

The echo's were too much for me ; I substituted them for $out (code be made even cleaner, but this is a start).

function createArticle($el){

	$out = '';

    //$el->setOutputFormatting(false);
    $title = $el->getLanguageValue('default', 'title');
    $titleFR = ($el->getLanguageValue('fr', 'title') ? $el->getLanguageValue('fr', 'title') : $title);
    $titleNL = ($el->getLanguageValue('nl', 'title') ? $el->getLanguageValue('nl', 'title') : $title);

    $out .= '  <div class="close closeArticle"><span>×</span></div>';
	//$out .= ($el->title ? '<h2>'. $el->title .'</h2>' : '');
	$out .= ($el->title ? '<h2>'. $titleFR .'</h2>' : '');// @note: just for testing
    $out .= ($el->sous_titre ? '<h3>'. $el->sous_titre .'</h3>' : '');
    $out .= '<div class="dates">';
	$out .= ($el->date_debut ? '<h4 class="dateDebut"><span></span> ' . $el->date_debut . ' </h4>' : '');
	$out .= ($el->date_fin ? '<h4 class="dateFin"> <span>  ⤑  </span> ' . $el->date_fin . '</h4><br>' : '');
	$out .= ($el->vernissage ? '<h4 class="vernissage"> <span>vernissage : </span>' . $el->vernissage . '</h4>' : '');
    $out .= '</div>';
    $out .= ($el->images ? '<img src="' . $el->images->first()->url . '" alt="" />' : '' );
    $out .= '<div class="content">';
	$out .= ($el->contenu ? $el->contenu : '' );
    $out .= '</div>';
    $out .= ($el->en_savoir_plus ? '<p class="savoirPlus">' : '' );
	$out .= ($el->en_savoir_plus ? '<a href="' . $el->en_savoir_plus . '" target="_blank">En savoir plus</a>' : '' );
	$out .= ($el->en_savoir_plus ? '</p>' : '' );
	
	return $out;

}

I have not looked at the rest of your code in detail...

Thank you very much for the answer, I'll try this as soon as possible. And you're right, this is dirty testing code.
