Quick search revealed at least 2 dependencies (intl module for PHP and ICU libs). See e.g. stackoverflow.com/questions/22875431/i-get-this-error-collator-create-unable-to-open-icu-collator-u-file-access-err

Do you have the required PHP modules to use the Collator class?

Thank you.
I changed all collations to utf8_persian_ci in phpadmin.
I also visited and used stackoverflow.com/questions/22796522/php-array-sorting-and-compatibility-with-persian-alphabets.
Unfortunately, the problem has not been solved yet.

I would recommend you follow the hints outlined here: stackoverflow.com/questions/22796522/php-array-sorting-and-compatibility-with-persian-alphabets

These will help to check if your server has the right locale and then you can use the "Collator" solution mentioned here stackoverflow.com/a/46765380/1157949 to do the proper sorting.

Thank you very much.
The link you have mentioned is exactly the same we use. Unfortunately, I am not skillful enough to perform what you have suggested. Would you please do me a favor and perform the necessary changes yourself?
Many thanks indeed!

So, I guess the sorting we do is not Persian friendly. The good news is that you can simply re-order the foreach loop in the mod_k2_tools tags.php override here: github.com/getk2/k2/blob/master/modules/mod_k2_tools/tmpl/tags.php#L16

Can you generally use e.g. sort() in PHP on your server to properly order alphabetically an array of Persian words?

Anyone know of a plugin or solution that displays K2 tags within a column in the K2 item manager? Something similar to how wordpress displays tags in the posts manager would be awesome.

Thank you for your quick reply.
You can see the desired order in right section of the following link, the actual order of letters must be as indicated by numbers, 1. 2, etc.:
transcoiran.com/k2/index.php/fa/

The alphabetical order in K2 menu category is now correct.
I need an email from you to send the control panel password, if it is needed. Or you may give me another suggestion so that i can keep it private.

The sorting mechanism is alphabetical already but perhaps it has trouble applying properly to Persian.

Can you send me a link to your site with the module on and let me know what the actual order should be so I can replicate it to my dev environment for testing?

yes that is right

Are you referring to the Tag Cloud option in the "K2 Tools" module (mod_k2_tools)?

Hi
I appreciate your hep regarding my question in the following link:
www.joomlaworks.net/forum/k2-en/46487-the-problem-in-view-of-k2-by-alphabetical-persian-ordering?limitstart=0

I have another question in the same field:
The Persian letters in the module tags K2 do not appear in lists in proper alphabetical order. To sort this module, which table of the database is to be changed?

Thank you for your assistance.

The template overrides may be outdated.

See this getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates and then create your own set or modify the existing overrides with new elements that may be missing.

Really, it's not difficult.

Thank you for support, Fotis!
But... When I open menu item, seted as K2 -> Tag - page title is OK - in <h1>. If I open tag page generated by K2, not from menu, page title is in <div>, not in <h1>.
I have selected "shine_magazine" in the item's K2 category and cleaned folder /html/com_k2/
I can't understand why changes in tag.php not displayed, and page titles still in <div>.
Please, help to resolve this issue!

First off, make sure you have selected "shine_magazine" in the item's K2 category. Secondly, cleanup your /html/com_k2/ folder. You should not use "templates" and having a folder named "item" will probably cause confusion in the long term.

Hi to everyone. I have a question about K2 extra field: it's possible to call inside the content one or more k2 extra fields tag?

If so which tag or call i will need to use? Thanks

I moved the folder my_template in com_K2, clean cache, but nothing change. H1 on header missing...

The correct path is /templates/my_template/html/com_k2/my_template/tag.php not /templates/my_template/html/com_k2/templates/my_template/tag.php for your overrides (not "templates" subfolder required anymore). If your overrides exist in such a subfolder move them all to /templates/my_template/html/com_k2/my_template/.

Remember to clean your site's cache.

You only should make this change in /templates/my_template/html/com_k2/templates/my_template/tag.php, not in K2's core files. Is your site live somewhere?

Hello,
Cannot changing <div class="componentheading"> to <h1 class="componentheading">
I trying make tag page title H1, changing <div class="componentheading"> to <h1 class="componentheading">, but without success.

Please, help!
