Let's assume that I have the following posts with the following titles:
- PostA (is assigned to the 'category 1')
- PostX (category 2)
- PostB (category 1)
- PostC (category 1)
- PostD (category 1)
- PostY (category 2)
- PostE (category 1)
When a visitor will read the PostC, how can I display in the sidebar:
'PostA' (these are links here, of course)
IOW the previous and the next 2 posts from the same category. (If a post has more categories we will choose the 1st one or the last one - it doesn't matter very much).
Also, if it is impossible to display the prev & next two posts it is acceptable also only one previous and next post. (I know that there are some WP functions for this but we prefer if it's possible two posts).
Also, of course, we want to display the first 'n' characters from the title (let's say 22). We don't want to display a static text like 'Next Post' or similar.
