Extra Fields Value NULL was created by quebecguitare

Hello, I've been trying for weeks to return the value of some extra field I have in a category. We would like to return them on the category_item.php template layout just under the header. The content of the extra field value that we want is a short description of the item.

I've been working with Gavick's support but we couldn't find the data of these fields on the database:
www.gavick.com/forums/university-joomla3/k2-layout-category-item-extra-field-42956

Here is the latest post from Gavick:

I've tried with this code, but it has the same problem I was talking about before. Extra fields are not picked from database for this. I've checked dump for the whole item and the only place it's used is in search fields. Here is an image with the content of extra fields when the regular K2 display is used. As You see only 3 elements are there and all the rest is presented in dump as NULL.

This must be codded somewhere deeper in core K2 functions. I think K2 developers will be more suitable here to help.

With a dump we could only retrieve these values:

(We are looking for the Extra Field 13 value, named "Résumé" / Alias: coursresume)

object(stdClass)#974 (8) {
    ["id"]=>
    string(2) "13"
    ["name"]=>
    string(8) "Résumé"
    ["value"]=>
    NULL
    ["type"]=>
    string(8) "textarea"
    ["group"]=>
    string(1) "2"
    ["published"]=>
    string(1) "1"
    ["ordering"]=>
    string(1) "3"
    ["alias"]=>
    string(11) "coursresume"
  }
  [3]=>

Here is the code used in category_item.php:

               <?php $extrafields = array(); ?>
               <?php if( is_array( $item->extra_fields ) ): ?>
                  <?php //convertArray to use ids as key
                     foreach($item->extra_fields as $extraFlds){
                        $extrafields[$extraFlds->id] = $extraFlds->value;
                     }
                  ?>
               <?php endif; ?>                                                  

               <?php if ($this->item->params->get('catItemTitleLinked')): ?>
                  <a href="<?php echo $this->item->link; ?>"><?php echo $this->item->title; ?></a></br>
                  <?php if($extrafields[13]): ?>
                     <a href="<?php echo $this->item->link; ?>"><?php echo $extrafields[13]; ?></a>
                  <?php endif; ?>
               <?php else: ?>
                  <?php echo $this->item->title; ?>
               <?php endif; ?>

Maybe I am doing something wrong?

These are my extra field, they are used for the template Suivi_K2:

Nom Groupe Type Publié(e) Id

Alias: AvatarProf Suivi en ligne - K2 Image 9

Alias: DateduCours Suivi en ligne - K2 Date 10

This is one of the category with the template Suivi_K2 assigned:
www.quebecguitare.ca/suivi/guyla ... -m-quebec/

This is one K2 Item under that category with the extra_field_13 that contains a value:
www.quebecguitare.ca/suivi/guylaine/cours-de-guitare-classique-de-mathis-m-quebec-1

--The ExtraField13 is named "Résumé" and within this K2 Item contains the following value that we should see in the header of the category_item layout: "Bonjour Lucie, voici le Suivi pour le cours de cette semaine. On a pratiqué les pièces pour le concert. Ça va bien aller, Mathis a très bien pratiqué.

J'ai remarqué que Mathis est maintenant capable de jouer plus fort. C'est très bien. Bravo Mathis!!"

Hello,

The category item's template required $this->item. eg:

<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>

You can also try to render a specific extrafield like this:

$this->item->extraFields->EXTRAFIELDALIASHERE->name 
$this->item->extraFields->EXTRAFIELDALIASHERE->value

Hello Krikor,

Here is the reply I had from my support at Gavick (I am a developer but not a programmer):

Yes we have tried that but it was not working ;/ It lists extrafields but from unknown reasons the value for extrafield with id 13 is NULL. But the other method is something new. I do not recall this values from a dump, but K2 developers must know better. It's their code :)

@qguitare

Does the specific extra field contain value? Do you see it's value when you edit the item in the administration? Finally note that extra fields are also parsing content plugins, so you might need to disable for a while some of them to detect the issue.

Try to:

1. Use a different template to see if the issue is only related with your current template. You can also call the page by appending "?template=system" to the URL.

2. If the above does not work try to disable some content plugins as i already wrote.

Hello, Some 3 months later I still have the same problem.

I cannot retrieve K2 Extra Fields in the Category_Item View. It returns NULL.

1. We have tried on another template and it doesn't work. So it's not the template.

2. Which plugin would you suggest to disable?

Would it be possible to have somebody looking at my site for this with login info and FTP access?
I am not a developper, I am bit frustrated here.

Try disabling these one by one to see if one of them is causing this issue.
