WordPress permalinks: only using the post_id from the URL

3 Views

I’m trying to have SEO friendly URLs for my wordpress blog, while still having the flexibility to change a post’s title at will.

My permalink structure would be like this:

Read More

%post_id%/%postname%

However, I’d like wordpress to just consider the %post_id% from the URL when looking for the appropriate post (sort of like here on stackoverflow)

For example:

https://stackoverflow.com/users/810/crossbrowser is the same as https://stackoverflow.com/users/810/hello-world

I’d like all of these to point to the same post, the one with id 345: 

http://myblog.com/345/the-name-of-the-post
http://myblog.com/345/any-text
http://myblog.com/345

The documentation mentions something that seems like what I’m trying to do: Long permalinks, but I couldn’t get it to work.

Here’s my .htaccess file: 

RewriteEngine on
RewriteBase /

# Let wordpress use pretty permalinks
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# From the example in the documentation
#RewriteRule /post/([0-9]+)?/?([0-9]+)?/?$ /index.php?p=$1&page=$2 [QSA]

UPDATE

I keep trying this RewriteRule in this online regular expression testing tool, but it doesn’t work when I put it in my .htaccess (just after RewriteBase): 

RewriteRule ^([0-9]+)/?([a-zA-Z0-9-]+)/?$ index.php?p=$1 [QSA]

  1. You could try the following rule:

    RewriteRule ^(d+)(/[^/]*)?$ index.php?id=$1 [L,QSA]

    But I don’t know if the substituion is correct. You have to check that by yourself.

  2. My response does not directly answer your question, but I think I have some points worth noting.

    I’m trying to have SEO friendly URLs
    for my wordpress blog, while still
    having the flexibility to change a
    post’s title at will.

    I’m not immediately seeing the benefit of your pursuit.

    The obvious disadvantage of including the %post_id% is that it makes the URL longer and contains non-semantic information. WordPress already deals with the scenario in two ways:

    1. The url (permalink/post name) doesn’t change when you change the title on a published post.

    2. If you do change the permalink, the old permalink continues to work and redirects to the new permalink.

  3. By using this tool, I was able to build an expression that matches everything in my list:

    http://myblog.com/435
http://myblog.com/435/the-post-title
http://myblog.com/435/the-po
http://myblog.com/435/asdf
http://myblog.com/435/the-9887-title
http://myblog.com/435/123

    The expression is:

    http://myblog.com/([0-9]+)/?([a-zA-Z0-9-]+)/?

    which would translate to this rule:

    RewriteRule ^([0-9]+)/?([a-zA-Z0-9-]+)/?$ index.php?p=$1 [QSA]

    however, it doesn’t work.

  4. I almost got it working by using this:

    RewriteEngine on
RewriteBase /

RewriteRule ^([0-9]+)?/?(^/+)?/?$ /index.php?p=$1 [QSA]

# Allow pretty permalinks
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

    however, it doesn’t always work and I’m not sure I understand why (or why it should work)

    It works with these:

    http://myblog.com/435
http://myblog.com/435/the-post-title
http://myblog.com/435/the-po

    but not with any of these:

    http://myblog.com/435/asdf (when there's no dash)
http://myblog.com/435/the-9887-title (whenever there's a number in the post title)

    Any help?
