I'll note it down to add a re-order option in the coming versions.

Yes of course when it is selected it is indeed static. But I have about 40 options in the drop down that I display to user to choose between them :) So there I have to order them alphabetically.

In extra fields manager I could add an option in the end and transfer with the hand all the values to that direction but it is not working, because for the items that already a value has been assigned will break :)

So the most convienient way without not hacking the core is to add options in the end and then in the table of k2_extra_field to put to the right order

Thank you very much Fotis!

Looking forward of v3

Hi Fotis,

yes sure it would be an option. Another option that i found is to change the order inside the k2_exta_fields table for he specific values I want. So no hack is required.

It's possible, but it would require to hack core K2 files to enforce the order you want.

I don't see how these 2 are relevant. Have you installed any other K2 plugins in the meantime? Or change the order in plugins?

K2 extra fields don't support translating content to other languages at the moment.

There is a trick though you can do.

Create a different set of extra fields for each language. One for each language.

When you assign all these items into an extra field group, they will get loaded in the K2 item form (whose content CAN be translated and assigned to different languages). Then, all you have to do is simply fill in the extra fields of the respective language. E.g. if you're writing the Italian content, fill in the extra fields with Italian labels on them, not the French ones.

Finally, modify the foreach loop where extra fields are rendered, in order to hide empty values. So in item.php, change this (around line 253):
to this:
Done.

About CSS Grids, Fotis, I think using CSS Grids makes Reactive Design unnecessary. See the attacked HTML file.



This took about two hours start to finish. I am amazed at how much this accomplishes with just 130 lines of CSS.

I added a demonstration of how DIVs can be moved around on the page using CSS Grids so the CSS ended up becoming 266 lines instead of 130.

Sub-templating is still very important, however, because even though CSS Grids makes designing a template orders of magnitude easier, not all pages are going to require the same set of DIVs, or the same logic,and that is where sub-templating comes in very handy.

Hi there,

before the K2 2.9 Update i was able to get extraField-Values like this (dropdowns):

$item->extraFields->Ort->value

After the 2.9 Update, im not getting a normal Array with all Values but this:
["extra_fields"]=>
string(890) "[{"id":"3","value":["5"]},{"id":"33","value":["7"]},{"id":"31","value":["2"]},..................

I managed to build a Array i could work with:

$extrafields = json_decode($item->extra_fields, true);
$extrafields = array_combine(array_column($extrafields,'id'),$extrafields);

But since it only gives me the ID of the Dropdown Option (not the Value itself), i cant work with it.
The Values are visible in extra_fields_search, but they are not ordered or anything.

How can i access the Dropdown Values?

We are working on a fix, you can bookmark our repo in order to stay up to date.

Also, thank you for reporting this. Feedback is invaluable to us

Hello,

You can use an extrafield in order to replace the default link.
You will need to edit your overrides (category_item.php, tag.php, generic.php etc..)

Thank you Krikor and Fotis for replying.

If your plain user can modify content beyond items and categories and comments, make sure they don't have the above permissions when configuring their group.

If you mean by "core.admin" rights is what we have with Joomla ACL as Global Configuration --> Permission --> Author, then I believe I have not assigned them "Access Administration Interface" . But if you mean K2 ACL permission, then I do assign the Author "Access Administration Interface" in K2 ACL permission. Because if I don't assign them in Access Administration Interface of K2 ACL permission, he can not access K2 at back end administrator page at all.

The most simple yet logic solution that comes to my mind is to disable (or hide) the "change author" button and publishing state in K2 item editor for user without publishing right like we have on front end site editor. Well, at least that would prevent the user to "sneak into the hole".

Thank you. :-)

Greeting all...

First of all, thank you Joomlaworks for providing us so useful and wonderful extension K2 for free. It is great!

Ok, I just have found a problem which could cause a threat to our site, where user with very limited backend admin access can see, and take action on things they suppose NOT to do. I spent last few days on testing this issue in both local server and also online server. I can confirm this is really potential problem which can destroy the whole K2 articles in our site. To make it short, let's make it this way:

1. Fresh install Joomla 3.8.5.
2. Fresh install K2.
3. No other extension installed.
4. I (as Super User) create Joomla usergroup Author, and new Viewing Access Level called "Author" which includes Public, Registered and Author only (ticked).
5. I create a Joomla user named "author1" which will act as article creator. In Joomla user, I assign this user author1 to usergroup Author. Then import the user to K2 user. His ONLY job is to create K2 articles and edit his OWN articles when necessary via back end and NOT to publish it. To do so, I assign his permission via Joomla ACL as follow :

• Joomla global ACL, set the group Author to have backend Administrator login. That's it. The rest permission in this point is inherited.
• Still in Global Configuration, go to K2 permission tab. Set Author permission to allow CREATE and EDIT OWN. *I also have to set Access Administration Interface" to Allowed, in order to make the admin menu toolbar appear to the author while he is login to backend administrator. Otherwise he will not be able to access either component toolbar or any K2 section (panel) in backend administrator.* Save it.
• Go to admin menu Joomla Extension --> Modules --> Administrator. FInd the module "Toolbar", edit it and grant access to "Author"

If we do it correctly, we can now logout as Super User, and re-login to backend administrator as Author1 with limited view access.

What we see as Author1 in backend administrator Cpanel page is K2 stats (admin) , and K2 Quick Icons (admin) , while in toolbar he can see Components and Help menu. The Components will only have K2 sub menu, * with K2 FULL sub menu instead of only Items, category, tags, comments, media manager, and information! *

That means, using the toolbar this Author1 is able to access many unauthorized resources and take unauthorized action such as disabling any user available (despite their usergroup), and flag them as spammer!

It is true that when he tries to access (for example) the K2 Users page, he will be warned by red error box saying "Error you are not authorized to view this resource", but still the page is open and give him an access to many unauthorized option to take action such as disabling users, and flag users as spammers.

Ok, so what if I don't grant access of module toolbar to Author? Doesn't that mean he is still able to access K2 section via K2 Quick Icons (admin) menu in Cpanel when he logged in and NOT having full K2 menu in toolbar?

Yes... He will not see Component menu in toolbar. Thus he wont have any K2 submenu either. And he still be able to access K2 backend section through K2 Quick Icons (admin). The problem is, there is still a chance for him to easily "sneak" into the hole.

Let's say I don't grant access of module toolbar to Author in admin menu module. This author can access K2 backend section through K2 Quick Icons (admin). What he will see in the left menu are : Items, Categories, Tags, Comments, Media Manager, and Information only. No link to K2, Users, Usergroups, or Extra fields. The problem is, when he create new article (or editing his own) the K2 item editor will open. In this K2 item editor, he CAN change the author by clicking Author button... When he click it, K2 users page will open and again, he will be warned by red error box saying "Error you are not authorized to view this resource", but still the page is open and give him an access to many unauthorized option to take action such as disabling users, and flag users as spammers.



If you don't have any idea what was happening when someone click flag users as spammer to legit site contributors, it is big disaster. All their articles will be destroyed from database, and the user is deleted from K2 database table, the site turns out error 1056 database error etc in front end, etc... Well, at least that was what happen to me last week. The website down for a while. Lucky I got daily backup to restore (Thanks Akeeba!).

I am not sure if this is appropriate, but granting this user "Access Administration Interface" in global K2 permission ACL should not go that far. There should be a way where "Access Administration Interface" permission does not give him way to far access in K2 admin section. Instead, only permission given to him is accessible (like create items and edit his own).


The next thing is, he is able to publish his own article if he manage to edit his own article via backend admin K2 item editor. It is true, that if he goes to Items menu in K2, (where he will see list of articles), he can not click (un-tick) the published checkbox (doing so will not change the state of article) to make it published or unpublished. But if he manage to edit the articles, he is able to change the state of publishing via K2 item editor page (it will take effect after saving).


That's all for now, please bear my English. I hope JW developers can take a look into the problem and solve them in next release.

Thank you so much for all your effort! You guys ROCK!!

Above functionality is great, however it still uses the rather Spartanic standard K2 frontend submission form with all the custom fields for the category tucked away in the extra fields tab, not necessarily in the best possible order, and with virtually no formatablity. Especially the multiple choice field needs improvement. I'm looking for a K2 extension/plugin that will allow me to create formatted frontend submission forms that write the content directly to the K2 item table. Ideally, those forms should have conditional fields, depending on what the user entered in a field above, and features such as multiple tabs and accordion to make the form more user friendly.

Even better would be if such extension was also able to design the custom frontend layout template so that admin doesn't need to engage in php coding.

Hello and thank you for your interest in our product,

Unfortunately at the current moment each K2 item has a separate gallery.
You can use an extrafield in order to add additional galleries and have common galleries between items.

Hi,

I've had this problem intermittently on K2 items - each time I've resolved by deleting tags on the item, saving & then reapplying tags & saving.

But I'm now getting this on a menu item. The error is as follows:

Oh, dear, we have a 0

Any suggestions?

Thanks,

After some debugging and digging in, i found that the reason for that issue is a k2 plugin which I wrote for the client. That plugin uses that xml manifest file:

All the comment blocks show fields which cause the error. So with those fields commented out, the error does not appear. What is wrong with that configuration?

Let us know how it went :)

(Quite late answer)
@Krikor — Thanks for your answer, but I can't use Multiple Extra Fields Groups (MEFG) for K2 as my website is using extensively JA K2 Filter, which is not compatible with.
@Ronny Van Der Borght — Thanks. I will try your code.
