next/previous post

1. On main page (aka index) where normally more posts are listed/displayed – the next/prev link is just a “pagination” to not show zillion posts on a long-long page.
2. Since you have set to show 1 (one) post on your index – the prev/next will show the same amount of posts = 1.
3. The “Archive” title comes with your theme; never seen before
4. Links to the previous and next post are displayed (normnally) on the single post view.

5. Switch to another theme (just for testing) and set the # of posts to something higher than 1 – and you’ll see that everything you are asking for is working in an out-of-the-box WP install.

EDIT. And never double post – I am very inclined to delete duplicate posts…

I realized on the first post that I left out some info and I didn’t know how to edit it, sorry.

I found in theloop.php how to make the archive pages show the content. My only question remains in how to get a previous post link on the single posts. I don’t see any links there.

Check out the Default theme’s single.php file to see how it is done.

I know how it’s done, I just don’t know where to post the code.

Obviously in the single.php template file … where you want the links to appear. THat’s why I suggested to take a look at it in other themes.

I put it in what seems to be the right place, but the text is not a link. It is only a link if I put it before …?php include (TEMPLATEPATH . ‘/theloop.php’); ?>
but that messes up the layout.

Okay I changed it from “div class=alignleft” to “div align=left” and that made the links work, but now the previous/next links are on different lines. What should I do?

Two divs will never be on the same line… unless you do a little work around them.
Since in the Deafult this problem is solved (you just have to look at it, as I suggested above), I don’t understand why don’t you follow the advice: Study how it is done in other themes and apply the solution to your theme.

Well because it didn’t work as it did in the default, I had to change the div code, and now it doesn’t look right.

And I want to have the previous/next post links on the front page too, not just the single post. How do I do that?

because it didn’t work as it did in the default
That’s probably because you have to look at the style.css file, too – to achieve the same effect ??

And I want to have the previous/next post links on the front page too
Out of the box that doesn’t work. The Wp engine recognizes whether it’s an index or a single post view and doesn’t let you use single-specific code on index.
