"How to display k2 extra field just beside the image of k2 item"

Thanks :kiss:

First of all you will have to create K2 template overrides. Read here on how overrides work getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates

Then you will have to modify the item.php file in order for this particular extra field to show next to the image.
After you have located the itemImage block of code you can target the specific extra field through these lines of code:

You will probably want to place them in a <div class="YOUR_CLASS"> container in order to style them afterwards and place them next to your image.

Is it possible to use similar code in the K2 item description to display an extrafield value?

<?php echo $this->item->extraFields->alias->value ;?>

When I try using nonumber.nl Sourcerer in order to put PHP code in the K2 Item I get this error:

Fatal error: Using $this when not in object context in /home/goodwin/public_html/xjoomla/plugins/system/sourcerer/helper.php(552) : runtime-created function on line 7

Nonumbers support states that it didn't work because, "That's because $this->item-> is not known. Sourcerer doesn't magically create that variable for you. "

Please help me display extrafields using JCE in a K2 item description.

You cannot call up a variable like that through the editor I'm afraid. You need to use it in the item.php located on your template overrides.

I have successfully been able to make those calls in the item.php on other projects. Here is a good example: www.modernmagic.com/blog/joomla-technical-support/k2-table-like-list-in-category-view.html


The whole reason for using K2 on this latest project is for the extrafields, so it would be great to use them in the K2 item description.

Is it possible to create the K2 object that contains that K2 item.
So your code would en up like:

$k2 = someK2Function();
echo $k2->item->extraFields->alias->value ;

Or:

$k2 = someK2ItemFunction();
echo $k2->extraFields->alias->value ;


Do you think it is possible with some custom k2 plugin, custom development, etc?

Hi Jeff,

I've never tried this, but what if you used a custom short code, like {extrafield name}, in the item description, and the do a replace of the shortcode with the extra field value in the sub-template?

The {extrafield alias} is exactly what I was thinking.

Where can I learn to "do a replace of the shortcode with the extra field value in the sub-template"?

PHP's str_replace function should do the trick (php.net/manual/en/function.str-replace.php)

So, something like:

$extrafieldvalue = $this->item->extraFields->THE EXTRA FIELD ALIAS->value;
$this->item->description = str_replace('{extrafield alias}', $extrafieldvalue, $this->item->description);
