Hi all,

i have a problem while trying to get extrafields information of an item in an external page of K2.

 

I'm using jxfinder to search k2 item, in the search-result page i want to add extrainfo of the item.

 

I've see that k2 use this one:

 

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

### code ###
<?php endforeach; ?>

 

Now, i have the id of the item but sure cannot use $this->item, is there a way to get extrafield of an item starting by the id?

 

Thanks,

Andrea

Not sure what you mean by external page.

I create an array inside item or category_item.php to get at the xtra fields - may help

$custom = $this->item->extra_fields;and then addressing extra fields for the item likeecho $custom[1]->value;

yes, but i'm requesting item extrafield external from k2, actually inside jxfinder search result, where i want to display the requested item and append image and extrafield of the item from k2.

 

So the $this->item->extra_fields it's not ok....i "managed" to get the extra_fields of the item by SQL, then explode and trim the string while not reach the values. I hoped there was an easy way :)

Due to the way k2 puts xtra fields in one sql field and stores images with a generated name, i dont think there is going to be an easy way, have to recreate the code that k2 uses to dig them out and use it just after you have gathered your search results in external program - doable, but not easy:(

infact as i said i managed to get the extra_fields column of a certain item ID and save the result in a var, the result is something like:

[{"id":"a","value":"b"},{"id":"c","value":"d"},{"id":"e","value":"f"}] etc etc

 

After that i exploded, trimmed and used a FOR to get the values. 

If someone need help in all of this just contact me...so SOLVED.

 

Anyway thanks William for the replies :)

Hello, I have the same problem. I´m trying to call the values of the extrafields in a module ( The module is Captify content).In the helper. php of the module i declare ( following instructions from other posts):$item->prueba = $item->extra_fields;

And in the default.php of the module i call the extrafields with this;<?php echo $item->prueba;?>The result is like yours:[{"id":"a","value":"b"},{"id":"c","value":"d"},{"id":"e","value":"f"}] etc etcBut now i don´t know how to get the values, could you show me how you do it?Thanks in advance! and sorry if my english is not good... I´m from Argentina.I would really apreciate your answer because i´m really stuck in here.Rosy,

Hola soport :)

first of all it's a hell of a work, you will get all those values from the data and it's ok...now you have to use php string functions to cut first by the { } and then by the , and last by : .

As you can see the data is repeated the same....so i've made a function that separate id from data and get the value. 

All i've used is explode PHP and some other php string functions.

 

I'm not at work now, maybe if you're still stuck i'll copy you some of my code ok?

Hey, thanks for your quick reply :)

 

After a lot of searching and testing i finally made it work!! I´m really newbie in php so i don´t know if this is the best way to do it. Here it is:

In helper.php I added:$item->prueba = json_decode($item->extra_fields); 

 

And In default.php:<?php echo $item->prueba[0]->value;?><br />

<?php echo $item->prueba[1]->value;?> [0] is for the first extra field, [1] por the second, etc.

This forum is really usefull, so i hope my answer could help someone else.Thanks again! 

works better than all my code :) thanks soport...never know about json_decode :)

 

Thanks to you..

I want to do the same thing with mod_k2_content. Where do I put this line in the helper.php ?
