Hallo,

I have a blog with professional articles- but some of them are written by many authors, not only by one.
Can someone help me to add a secont author?

Or do someone hava a tip how I could show the secont author?

thanks for your help, yvonne

You could add an extra field for this purpose.
For instance: A field for the authors name, one for his/her email etc...

If you need 'unlimited authors' you could check Joomreem's exellent Dataset plugin: www.joomreem.com/extensions-store/k2-datasets#.WYQmFIppxMM
You can use this to make datasets from your extra fields.

But this would need some template customisation.

Ronny you rock :)

Hallo, thank you for your idea.
I already tried to use the extra fields, but I want to use the 'author site' . when I choose the author I want to see a list of all articles and i use a filter where I need the author.

maybe someone knows which php-files I have to change to add a second author field in back- and fronted.



..and sorry for my english ;)

Your English is perfectly fine.
Keep in mind that you can render a specific extrafield's value in your site.
So you can have both the link as an extrafield (text field or select element) and the name of the author in one HTML element in order to build your link.

A basic example can be found here:
github.com/kricore/Advanced-templating-with-K2/blob/master/_inc/cheatsheet.php#L168-L173

The item's php file is the item.php file and always use overrides.
getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates

I guess you could even use the K2 tags for this. I used it once like this:
1. Add the Authors as tags (John Doe, Peter Sellars, Peter Falk, etc...)
2. Add a new K2 category named 'Authors'
3. Add a K2 item for every author, use extra fields for the specifics
4. Attach the corresponding tag to the k2 item (The k2 item for 'John Doe' gets the tag 'John Doe')
5. Finally: Link all the other articles with the authors k2 tags

Now change your k2 templates. Work with the 'related items by tag' options.
Example for item.php (always work with overrides!!!):
change: <span><?php echo JText::_('K2_TAGGED_UNDER'); ?></span> into <span>Authors:</span>
and
change <h3><?php echo JText::_("K2_RELATED_ITEMS_BY_TAG"); ?></h3> into <h3>Other articles by this author</h3>
You could even change tags.php.



Tip for advanced k2 users: If you don't want the k2 item for the authors itself (from the k2 category 'Authors') to show up in the list for the articles you could add an exeption to the foreach loop like this:

Change:
<?php foreach($this->relatedItems as $key=>$item): ?>
<!-- author block -->
<?php endforeach; ?>
Into:
<?php foreach($this->relatedItems as $key=>$item): ?>
<?php if($item->category->name !=="Authors"): ?>
<!-- author block -->
<?php endif ;?>
<?php endforeach; ?>

Using this concept you could have 2 related items blocks: one that pulls the author(s) info and one that pulls the articles.

Thanks a lot for your help!

I will try to realise your ideas.

Nice one :)
That's a clever solution.
