I'm stumped: I can't figure out how to use the "Co-author plus" plugin with in the Thematic-Acamas platform. It requires modifying code within template pages; however, the instructions are vague and don't correspond to the code I see in the templates. I'm grateful for any help you can provide. Thanks.

Don't you have any alternative to this plugin??

This plugins only echoes the results. You need something that returns a value.

Here are the three plugins I know about:

I'm not aware of another way. And it seems this discussion says as much:

Yes! I'm stumped with this problem, too. I'd be grateful if someone could help explain how to display co-authors within the Thematic framework.

Best,
Jacob

.. will contact the plugin author to provide a function that returns the value.

There's another way to do this right now, but this is not my favorite way to solve this problem.

Could I trouble you to explain the no-so-favorite solution? I'm on deadline for a project and can't figure out how to make co-authors and Thematic play nice.

Thanks.

I'm also interested in using the co-authors plus plugin. Unfortunately the plugin's functions do not seem to return a value, and so it doesn't look that easy to edit the thematic hooks-filter.php to return the multiple authors.

Hi,

take a look here: http://forums.themeshaper.com/topic/using-wp-postratings#post-1732

The solution is similar.

Will post the code for co-author plus later today.

Ok .. the code would be:
```
function the_coauthor() {
	ob_start();
	coauthors_posts_links();
	$content = ob_get_contents();
	ob_end_clean();
	return $content;
}
```
You might want to add some more data to coauthors_posts_links() (see its documentation). the_coauthor will return the needed data to filter entry-meta.

Haven't tested this code. Please let me know if it works.

Where would you put this code if you are using your own child theme?

I pasted the function in the functions.php file of my child theme, added "the_coauthors()" to my postheader, and it worked like a charm. Thanks so much!

I pasted Chris' code as a function in my functions.php file in my child theme, and then copied and renamed the post header function, like in the guide. However, I am not sure where to put "the_coauthors()" in the customized post_header function.

Without any warranty:

Change the following code from Björn's guide:

$postmeta .= '<span class="author vcard">';
    $postmeta .= __('By ', 'thematic') . '<a class="url fn n" href="';
    $postmeta .= get_author_link(false, $authordata->ID, $authordata->user_nicename);
    $postmeta .= '" title="' . __('View all posts by ', 'thematic') . get_the_author() . '">';
    $postmeta .= get_the_author();
    $postmeta .= '</a></span><span class="meta-sep"> | </span>';

to:

$postmeta .= '<span class="author vcard">';
    $postmeta .= __('By ', 'thematic');
    $postmeta .= the_coauthor();
    $postmeta .= '</span><span class="meta-sep"> | </span>';

This seems to work but when saving the post, I get the following error:

Warning: Cannot modify header information - headers already sent by (output started at [mydomain child theme folder]/functions.php:103)in [mydomain]/wp-includes/pluggable.php on line 865

The post shows up correctly in previews, but I get this error whenever I try to modify/save the post.

No problem here.

This is the code I used in my functions.php:

function the_coauthor() {
	ob_start();
	coauthors_posts_links();
	$content = ob_get_contents();
	ob_end_clean();
	return $content;
}

function my_postmeta() {
    global $id, $post, $authordata;
    $postmeta = '<div class="entry-meta">';
    $postmeta .= '<span class="meta-prep meta-prep-author">' . __('By ', 'thematic') . '</span>';
	$postmeta .= '<span class="author vcard">';
    $postmeta .= the_coauthor();
    $postmeta .= '</span><span class="meta-sep"> | </span>';
    $postmeta .= '<span class="meta-prep meta-prep-entry-date">' . __('Published: ', 'thematic') . '</span>';
    $postmeta .= '<span class="entry-date"><abbr class="published" title="';
    $postmeta .= get_the_time(thematic_time_title()) . '">';
    $postmeta .= get_the_time(thematic_time_display());
    $postmeta .= '</abbr></span>';
    // Display edit link
    if (current_user_can('edit_posts')) {
        $postmeta .= ' <span class="meta-sep meta-sep-edit">|</span> ' . '<span class="edit">' . $posteditlink . '</span>';
    }
    $postmeta .= "</div><!-- .entry-meta -->\n";
	return $postmeta;
}
add_filter('thematic_postheader_postmeta', 'my_postmeta');

... and thanks to childtheme overrides you can achieve that also like this:

// support multiple authors using Co-Authors Plus plugin
function childtheme_singleauthorlink () { global $authordata; $result = ''. '<a class="url fn n" href="'; $result .= get_author_posts_url($authordata->ID, $authordata->user_nicename); $result .= '" title="' . __('View all posts by ', 'thematic') . get_the_author() . '">'; $result .= get_the_author(); $result .= ''; return $result; } function childtheme_override_postmeta_authorlink() { $i = new CoAuthorsIterator(); if(function_exists('coauthors_posts_links')) { $authorlink = '' . _n('Author ', 'Authors ', $i->count(), 'childtextdomain') . ''; $i->iterate(); $authorlink .= childtheme_singleauthorlink (); while($i->iterate()){ if (!$i->is_last()) $authorlink .= ', '; else $authorlink .= __(' and ', 'childtextdomain'); $authorlink .= childtheme_singleauthorlink (); } $authorlink .= ''; } else { $authorlink = '' . __('By ', 'thematic') . ''; $authorlink .= childtheme_singleauthorlink (); }
return apply_filters('thematic_post_meta_authorlink', $authorlink); }

@Chris

Your functions.php snippet works for me! Thank you very much.

But, it does not apply the link styles to the_coauthor(), namely the class="url fn n".

Also, the post 'Edit' link does not appear after the '|' character.

Thanks for any insight!

Cheers,
Joe

Actually I decided to stop using this plugin ... thanks anyway. Cheers!

So my next thought is, can additional authors be added to a post using custom fields and then displayed publicly using thematic_post_meta_authorlink? Without using any plugin. If anyone knows this, please speak up! If I get it figured out, I will of course share my solution. Thanks!

Sweet, I've got the core functionality figured out, at least. I need to add style and also would like to make coauthors names link to their additional posts, but this keeps me publishing for yet another day and I can figure the rest out with time.

NOTE this does NOT use the PLUGIN mentioned at start of this thread. This uses no plugin whatsoever, only added this inside my child theme's functions.php and use "Coauthors" as the name of the custom field in the posts.

//  add additional authors to posts where "Coauthors" is the custom field
function my_post_meta_authorlink() {

	    global $authordata, $post;

   $coauthor = get_post_meta ($post->ID, 'Coauthors', true);
	    $authorlink = '<span class="meta-prep meta-prep-author">' . __('By ', 'thematic') . '</span>';
	    $authorlink .= '<span class="author vcard">'. '<a class="url fn n" href="';
	    $authorlink .= get_author_posts_url($authordata->ID, $authordata->user_nicename);
	    $authorlink .= '" title="' . __('View all posts by ', 'thematic') . get_the_author_meta( 'display_name' ) . '">';
	    $authorlink .= get_the_author_meta( 'display_name' );
	    $authorlink .= '</a>';
	if ($coauthor) {   $authorlink .= ', ' . $coauthor;  }
	    $authorlink .= '</span>';

    return $authorlink;

} 

add_filter('thematic_post_meta_authorlink','my_post_meta_authorlink');

Also please note there is likely some more efficient way of doing this; I am just a learn-as-I-go PHP guy, and this is working for me right here and now. Improvement suggestions very welcome!

Cheers

Ah, the linking and styling was easier than expected; just use the $coauthors variable to fill in the link address and title blank spots, all wrapped in the appropriate span and link css class

//  add additional authors to posts
function my_post_meta_authorlink() {

	    global $authordata, $post;

   $coauthor = get_post_meta ($post->ID, 'Coauthors', true);
	    $authorlink = '<span class="meta-prep meta-prep-author">' . __('By ', 'thematic') . '</span>';
	    $authorlink .= '<span class="author vcard">'. '<a class="url fn n" href="';
	    $authorlink .= get_author_posts_url($authordata->ID, $authordata->user_nicename);
	    $authorlink .= '" title="' . __('View all posts by ', 'thematic') . get_the_author_meta( 'display_name' ) . '">';
	    $authorlink .= get_the_author_meta( 'display_name' );

	    $authorlink .= '</a>';
	if ($coauthor) {   $authorlink .= ' and <span class="author vcard"><a class="url fn n" href="/author/' . $coauthor . '" title="View all posts by ' . $coauthor . '">' . $coauthor . '</a></span>';  }
	    $authorlink .= '</span>';

    return $authorlink;

} 

add_filter('thematic_post_meta_authorlink','my_post_meta_authorlink');
