How can i extra an extra field item based on the name if gave it  when i created it. I am new to K2 and php but what i have figured out so that the the extra field group is and array. this is also the additional info block on the standard k2 templateit looks like thisArray
(
[0] => stdClass Object
(
[id] => 1
[name] => RapidShare Link
[value] => Rapid Share
[type] => link
[group] => 1
[published] => 1
[ordering] => 1
)

[1] => stdClass Object
(
[id] => 2
[name] => authour
[value] => me
[type] => textfield
[group] => 1
[published] => 1
[ordering] => 2
)

[2] => stdClass Object
(
[id] => 3
[name] => Version
[value] => 45
[type] => textfield
[group] => 1
[published] => 1
[ordering] => 3
)

)


i need to just get the first one but based on the name but it may not always be the first on  and display it in my template so that when there is a extra field called RapidShare Link it will show.

this may be helpfull to start

thanks but that does not help as i will be using this in a template override. not what i am looking for still searching the web to find how to extract an stdClass from an array maybe that might help me get to the next point i my development.

I have used the $ custom = statement in overrides and then extracted the value in the position i want before, its always in the same place unless you change the number of xtra fields, and should be in the same place if you only add a field.

ok that is true but i intend to share my work with this community and if I do it the way you say then it would not work for anyone right out the box with out them going in the template code and editing it. i this i found a way o will post my results after some test in a few but i really appreciate you trying to help.

you will be the first to see my new template and get a copy if you would like just for trying to help it was very much appreciated.

Alex, if what you want is to extract an item from the extrafields array, just make a foreach loop on this array and test the element value :
// Code
foreach($myExtraFields as extraField) {
if ($extraField->value == 'myValue) {
$goodExtraField = $extraField;
break;
}
}

...Do what you want with $goodExtraField
//Code

Hello Olivier,
I think this solution you posted above is very close to what I need: I'm trying to call a especific extraFields and insert it on a HTML code I inserted in item.php.
But I`m new in PHP and K2, so would you mind help me in the details?
I understood that this code you posted above is supposed to replace this other in templates/default/item.php, at 253 line (or something close, my lines may have been changed after some editions):

//Code
foreach ($this->item->extra_fields as $key=>$extraField)
//Code

Is this?

If I'm right, how can I customize properly the code you posted? I mean, may I replace "$myExtraFields " with the name I gave to my extraField group? Then, what I exactly supposed to use has "myValue"? The name of a extraField created in a group? Thank you in advanced.

this oliver that really helped no i want to go one step further and extract your the url form the right not i cannot create a button as the link give area has text if you understand what i am say just want the raw url imputed buy user and nothing else. any ideas.

Hi all, is it possible to make it work with latest.php layout?

Thanks for the advice. I was also working on extracting only certain extra fields and surprisingly it works! Below is my code for those who still need a more concrete version:

//Code <?php foreach ($this->item->extra_fields as $key=>$extraField):?>            <?php if($extraField->name == 'Ort'): ?>            <li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">                <span class="catItemExtraFieldsLabel"><?php echo $extraField->name; ?>:</span>                <span class="catItemExtraFieldsValue"><?php echo $extraField->value; ?></span>                                </li>         <?php endif; ?>            <?php endforeach; ?>

//Code

Thanks for this code, but i have a little problem :

it works fine with one group of extra fields on one template (templatejoomla\html\com_k2\templates\nametemplate1) (> dev.feteduconte.agglo-sqy.fr/index.php/programme)

but it does'nt work with an other group of extra fields on an other template (templatejoomla\html\com_k2\templates\nametemplate2) (> dev.feteduconte.agglo-sqy.fr/index.php/bibliographie)

the nametemplate2 is recognized but he does'nt extract the extra fields...

Please how can i do ?

//Code

if($extraField->name == 'Ort'): ?>

is referring to an extra field with the name of Ort. If you have two groups of extra fields they will probably have different names

More efficient method.
