Hello,

You cannot just have <?php echo $extraField->value; ?> You need to define the extrafield itself in order to bring the value.

Try with this code

My subscription to this thread must not be working, because I did not get your reply.

In the mean time I had email you this question. But it appear you have already answered it.

If I have the same titled extra field in multiple EF groups and then use MEFG to assign multiple groups to a catgeory, will the duplicate EFs show in the K2 Item Extra Field tab?

For example, will the EF: "Tires" only show once since it is a duplicate?
EF Group: Cars
--- EF: Tires

EF Group: Motorcycles
--- EF: Tires

K2 Category: Vehicles
--- EF Groups: Cars and Motorcycles

---

EF: Tires

And, how is the ordering of EFs on the item page controlled when I choose multiple EF groups for a k2 cat?

Hi,

I have been using K2 on a Joomla 1.5 site and now am upgrading to Joomla 3.x. When I needed to access the extra field values in one of the template pages I had a foreach loop that walked thru the extra fields until I found the one I needed and got its value. This worked from categories, items, and tag templates. Now with the new Joomla 3 version of K2 the categories and items templates have the same structure as they did in Joomla 1.5 and I can get the values that I need. But for some reason the tag structure is totally different for the extra fields.

For categories and items the extra fields structure looks like this:
Array
(
[0] => stdClass Object
(
[id] => 1
[name] => Street Address
[value] => 602-1888 York Avenue
[type] => textfield
[group] => 2
[published] => 1
[ordering] => 1
[alias] => StreetAddress
)

[1] => stdClass Object
(
[id] => 2
[name] => Price
[value] => 389000
[type] => textfield
[group] => 2
[published] => 1
[ordering] => 4
[alias] => Price
) ...

But on the tags page the structure looks like this:
[{"id":"1","value":"602-1888 York Avenue"},{"id":"2","value":"389000"},...

I need to get the 'Price' from the extra fields which is: 389000. So id 2's value. How to I code this so I can get out the value of id 2?

I tried:
[code
]foreach ($fields as $key=>$extraField):
if ($extraField->id == '2') {
$price = $extraField->value;
endforeach;
[/code]

But that isn't working, it gets an error:
Warning: Invalid argument supplied for foreach()

Any help would be appreciated.

Thank you.

You can achieve that by using an extrafield. The extra field will hold the external URL and it will replace the actual url of the item in your lists.
You will have to create a K2 template override in order to modify the category_item.php file. Read here getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates on how K2 overrides work if your template doesn't use them already.

I also very much need this capability to re/order values for extra values as lists grow/change. The lack of this capability is an EXTREME limitation on extra fields.

Hello!

I'm currently trying to edit the backend item form (administrator/components/com_k2/views/item/tmp/default.php) in order to add a javascript call to a specific extra field, the code I'm using is as follows, in line 561 of the deafult.php file:

The code should add "onchange="checkseleccion()" " to an extra field with the id K2ExtraField_1, however it isn't working in the backend. In the front end submission form it works perfectly.

Is this the file I should be editing, or there's some other place where I can access the extra field code to add the function?

Thanks in advance!

Joomla: 3.1.5
K2: 2.6.7

I tried the fisrt part by copying your code to the right file and it's perfect! All the plugins are in the order I wanted them to be.

But I dont understand exactly the second part with the custom.css.
I copied the code in the file. Have a look if I'm doing something wrong.

/* Add custom CSS code here for easier template updates */

.itemBody .itemContentLeft {margin:0 20px 20px 20px;}

What is the purpose of that change? I was expecting to fix the margins around the extra fields block, but the way I did nothing changed.

I would like to ask you if it is possible for someone like me (with not much of css knowlegde) to change the order of the K2 features after the articles?
I could really use 3 basic changes.
1) I would like to have my text in the articles wrapping under the extra fields block because now the text length its getting very short.

2) Is it possible to get the video block after the text and before the "author", "latest from" and "related articles"?

3) and the last one...can I move the "social icon" and the "rating" line before the image and text and after the anchor icons?

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.

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.

K2 Tools is not intended to display item lists. You need to use K2 Content istead in order use this snippet.

Hi Krikor Boghossian

Thanks so much for your time with support me, I click on your link and try it, but it's still ExtraFiled value as (label) instead of number ordering value as I need.

As i saw in database: written as , Example, "value":1, "value":2,....

below as in DB

{"name":"One","value":1,"target":null,"alias":"test","required":1,"showNull":0},{"name":"Two","value":2,"target":null,"alias":"test","required":1,"showNull":0},{"name":"Three","value":3,"target":null,"alias":"test","required":1,"showNull":0}

I really need value in number as I highlighted in red color:

So what i need get value from as ordering number as 1 or 2 or 3, because need to make dynamic link for search function.

Thanks

Best Regards

Yo creo que si desde el formulario logro sustraer toda la informacion podria generar una consulta similar a la que pego al final para insertar y crear el item.

La pregunta es que pasa si tengo galerias de fotos, videos, contenido media?

Since I am at a little loss of what it is that you actually want to achieve with your extrafields would you be kind enough to revise it for me in order to get it right and sent you the file back as you want?

Thank you.

You will have to add the following CSS in the custom.css file located in templates/nokkori/css/

Hello,

is there a possibility to create a hierarchy of extra fields? I recently bought k2 search module, which uses such a thing in order to set up 'connected fields' search, but I somehow cannot find out how to do it...
