Al my posts are alphabetically, now i would like to see the navigation in single post pages to show alphabetically aswell.

Is there a way?
note that not all posts are in the same catagorie, but even then they should be alphabetically.

Help would be much appreciated

Be default, posts show in the order they were published. Have you used a page template to make changes?
What version of Atahualpa and WP?
What is the url?

There are plugins that will display posts alphabetically as one of the options. Link Category Posts is the first that comes to mind.

I used:
Post Sorting Reloaded plugin to alphabetically order posts in categorie pages, I'm also using link category post to get lists of all my categories alphabetically on a "view all post" page.
but the navigation on 1 post on page pages is still not alphabetically.

I've got the most recent atahualpa and wp and i didn't change the page template (as far as i can remember). Here's an url that shows what im talking about:
http://www.bushcraftvereniging.nl/wiki/pemmican/

You see the post "Pemmican"
The next is trapper and the previous is bannocks.. but there should be a lot between the b and p.
(note that this page was only created 3/4 days go and is still very empty)

The next previous links are still based on chronological order. I just did a Google search for "wordpress next previous alphabetical" and came up with a link that sent me to this plugin which might be what you need.

Often a quick Google search or a search at wordpress.org will help with things along these lines.

To make that work i need to find the "next_post_link" and "previous_post_link " tags...
it said to be in single.php but i can't seem to find it?

this is what i need to put "somewhere" i guess:

<?php next_post_link_plus( array('order_by' => 'post_title') ); ?>

Atahualpa sets up the next/previous links via calls to the wordpress functions 'next_post_link' and 'previous_post_link' in bfa_nexr_previous_links.php

Note there are several places it calls them based on the type of page and it uses the options from ato->Next/Previous Navigation settings

The single post pages are the only ones that mather to me,

/* Next/Previous POST Links (on single post pages)
   in next_post_link "next" means newer posts
   Available parameters for $location: Top, Middle, Bottom. Default: Top  */
function bfa_next_previous_post_links($location = "Top") {

global $bfa_ata, $homeURL;

	if ( is_single() AND strpos($bfa_ata['location_single_next_prev'],$location) !== FALSE AND
	
    // don't display on WP Email pages
    intval(get_query_var('email')) != 1 )  {

		echo '<div class="clearfix navigation-'.strtolower($location).'">
		<div class="older' . ($bfa_ata['home_single_next_prev'] != '' ?
        '-home' : '') . '">';

		if ($bfa_ata['next_prev_orientation'] == 'Older Left, Newer Right') {
			if($bfa_ata['single_next_prev_same_cat'] == "Yes") {
				previous_post_link($bfa_ata['single_next_prev_older'], '%title', TRUE);
			} else { 
				previous_post_link($bfa_ata['single_next_prev_older']);
			}
		} else {
			if($bfa_ata['single_next_prev_same_cat'] == "Yes") {  
				next_post_link($bfa_ata['single_next_prev_newer'], '%title', TRUE);
			} else { 
				next_post_link($bfa_ata['single_next_prev_newer']);
			}
		}
		
		echo ' &nbsp;</div>';
		if ($bfa_ata['home_single_next_prev'] != '') { 
			echo '<div class="home"><a href="' . $homeURL . '/">' .
			$bfa_ata['home_single_next_prev'] . '</a></div>';
		}
		echo '<div class="newer';
		if ($bfa_ata['home_single_next_prev'] != '') {
			echo '-home';
		}
		echo '">&nbsp; ';

		if ($bfa_ata['next_prev_orientation'] == 'Older Left, Newer Right') {
			if($bfa_ata['single_next_prev_same_cat'] == "Yes") {
				next_post_link($bfa_ata['single_next_prev_newer'], '%title', TRUE);
			} else { 
				next_post_link($bfa_ata['single_next_prev_newer']);
			}
		} else {
			if($bfa_ata['single_next_prev_same_cat'] == "Yes") {
				previous_post_link($bfa_ata['single_next_prev_older'], '%title', TRUE);
			} else { 
				previous_post_link($bfa_ata['single_next_prev_older']);
			}
		}

		echo '</div></div>';
	}
}

Is the code,

changing

previous_post_link($bfa_ata['single_next_prev_older']);

to

previous_post_link_plus( array('order_by' => 'post_title') );

doesnt seem to work.

previous_post_link_plus

what widget is that from?

previous_post_link_plus

what widget is that from?

I installed 'Next/Previous Post Link Plus for WordPress' ad it worked for me - make sure you disable andy caching plugins you have.

It's from the above suggested plugin.
If there's a way to not use this plugin i would prefere it, but using it is hard enough aswell.
what would be caching plugins?

That is the plugin I tried it with and it worked fine.
It look like you DO NOT have a caching plugin active (like w3 total cache)

I simply got the plugin by searching for it at wp-admin panel and letting wp install it. Install was succesfull, But nothing happened. Do i need to do anything extra?

Well you have to make the changes to bfa_nexr_previous_links.php and make sure to make them to the next AND previous

I tried that the way i explained a few posts earlier.. but i think im doing something wrong?
is it possible to show me what i need to replace with what? Or maybe show me what you did?

Here is what I changed you can see the commented out lines

/* Next/Previous POST Links (on single post pages)
   in next_post_link "next" means newer posts
   Available parameters for $location: Top, Middle, Bottom. Default: Top  */
function bfa_next_previous_post_links($location = "Top") {

global $bfa_ata, $homeURL;

	if ( is_single() AND strpos($bfa_ata['location_single_next_prev'],$location) !== FALSE AND
	
    // don't display on WP Email pages
    intval(get_query_var('email')) != 1 )  {

		echo '<div class="clearfix navigation-'.strtolower($location).'">
		<div class="older' . ($bfa_ata['home_single_next_prev'] != '' ?
        '-home' : '') . '">';

		if ($bfa_ata['next_prev_orientation'] == 'Older Left, Newer Right') {
			if($bfa_ata['single_next_prev_same_cat'] == "Yes") {
previous_post_link_plus( array('order_by' => 'post_title') );
//				previous_post_link($bfa_ata['single_next_prev_older'], '%title', TRUE);
			} else { 
previous_post_link_plus( array('order_by' => 'post_title') );
//				previous_post_link($bfa_ata['single_next_prev_older']);
			}
		} else {
			if($bfa_ata['single_next_prev_same_cat'] == "Yes") {

			} else { 
next_post_link_plus( array('order_by' => 'post_title') );				//next_post_link($bfa_ata['single_next_prev_newer']);

		}
		
		echo ' &nbsp;</div>';

I copied past yours and this is what i got:

Fatal error: Call to undefined function next_post_link_plus() in /home/******/domains/bushcraftvereniging.nl/public_html/wiki/wp-content/themes/atahualpa/functions/bfa_next_previous_links.php on line 111

I found the problem!

Thank you very much!!!
I had a wrong version of the plugin installed. It seems to work now!
