Hello,

I'm really loving new K2 feature <?php echo $this->item->extraFields->EXTRAFIELDALIASHERE->value; ?>

It has helped me a lot in last few projects.

Unfortunately I can't figure out how to use do this for related items in item view.

I added <?php echo $this->item->extraFields->EXTRAFIELDALIASHERE->value; ?> inside foreach loop, but with no success :(

I also noticed that related items use $item instead of $this->item in order to output elements. So I tried using <?php echo $item->extraFields->EXTRAFIELDALIASHERE->value; ?>, but I still couldn't output extra fields.

Could you please help?

Hello Uldis,

I am afraid you cannot extrafields in the related items. I think you should use the K2 content module for this functionality.

But If I use k2 content module I can only select specific items or items from category.

I would also need to create new module for each item :(

I really needed related by tag functionality because each items will have different related items.

Is there really no way? Related items by tag can get almost any information using
It just doesn't work with extra fields :(

There is no way, as i know it. Only paid modules but they are not what you want. They more or less pull related Items by Tags.

Hi Uldis,

This can be done by hacking the components/com_k2/models/itemlist.php file, at line: 955
add this line:after this line:
This way, you can useto show extra fields for related items.

Thanks Mohamed!
This really needs to be default in K2.

hi Mohamed
i trying to use your code and follow your instructions but its not working for me,maybe because im using the line: <?php echo $item->extraFields->EXTRAFIELDALIASHERE->value; ?> in item.php and i need to change "EXTRAFIELDALIASHERE" to something else but what?

i tried insted "EXTRAFIELDALIASHERE" to put the group name and alias of single extra field but its not working for me and no extra fields data.

what i doing wrong?

thanks

Hi moni,

EXTRAFIELDALIASHERE should be replaced by the field alias, you can get it from the extra fields manager at the backend.

But in item.php, it should be $this->item->extraFields, not $tiem->extraFields

hope this can help

Hi Mohamed

I was wondering whether it would be possible to take it a step further to show only those Related Items that share a common value in a given extra field.

For example, if 10 items are tagged "Apples", normally the Related items will show all 10 items tagged as "Apples". However, if only 7 of those items that are tagged "Apples" have the value "sour' inserted into an extra field called "Taste", then only those 7 "sour" apples will show up in the Related Items section.

Is that possible to do?
