The problem.
As you probably know, WordPress lets you decide whether to allow readers to create accounts and sign in to your blog. If you want to increase your blog’s registered readers or would just like to reward existing readers, why not keep some content private, just for them?
The problem.
Your blog has a lot of posts, but the posts aren’t all of the same type. To give special styling to one or more of your posts, you can take advantage of both the post_class() function and the post ID.
The solution.
To apply this trick, just open your single.php file, find the loop and replace [...]
The problem. Let’s say, for some reason, such as a hacking or upgrade problem, you have lost your blog data or it has become corrupted. If you have a backup (and I hope you do!) you will have to import it to your WordPress database.

Simply because, by default, WordPress turns normal quotes into so-called “smart quotes,” which breaks code snippets.
The problem. Using custom fields to display images associated with your post is definitely a great idea, but many WordPress users would like a solution for retrieving images embedded in the post’s content itself.
The solution. As far as we know, there’s no plug-in to do that. Happily, the following loop will do the job: it [...]
Sometimes you only want to show posts that you’ve added a specific custom field to. A typical post loop begins like this:
