Permalinks question

Hello f00bar,

Thanks for the suggestion. I have actually read somewhere else that it is better to use /%post_id%/%postname%/ structure for better performance, however when i tested it that way my original problem did not get solved.

Again http://www.mybwordpressdomain.com/post_id/postname/ and http://www.mybwordpressdomain.com/post_id/postname_with_spelling_mistake/ did not point to the same page. Instead the second one just gave 404 which is what i try to avoid.

Best regards.
Stefan

hello f00bar,

Because i’m migrating from non-wordpress platform and I have some spelling mistakes in links all over the internet. Don’t ask how that happened … just it’s that way. So I want to keep the links working as they are currently with the engine I use.

I have enabled full query log in mysql to see how wp engine tries to find the proper post to display. Proper postname is
burn-iso-image-with-nero-burning-rom

I tried to access the same article with
burn-iso-image-with-nero-burning-romance

Here is the result of mysql log

4 Query SELECT wp_posts.* FROM wp_posts WHERE 1=1 AND wp_posts.post_name = ‘burn-iso-image-with-nero-burning-romance’ AND wp_posts.ID = 10 AND wp_posts.post_type = ‘post’ ORDER BY wp_posts.post_date DESC
4 Query SELECT post_id FROM wp_postmeta, wp_posts WHERE ID = post_id AND meta_key = ‘_wp_old_slug’ AND meta_value=’burn-iso-image-with-nero-burning-romance’
4 Query SELECT ID FROM wp_posts WHERE post_name LIKE ‘burn-iso-image-with-nero-burning-romance%’ AND post_status = ‘publish’

So I want to find the place where the last select is generated and replace it with some query like

SELECT wp_posts.* FROM wp_posts WHERE 1=1 AND wp_posts.ID = 10 AND wp_posts.post_type = ‘post’ ORDER BY wp_posts.post_date DESC

So that it gets the proper result.

Hello f00bar,

First I want to thank you for you replies.

Here is what I did to solve my little problem.

I altered a bit the function redirect_guess_404_permalink in wp-includes/canonical.php

After

if ( !get_query_var(‘name’) )
return false;

I added

if ( get_query_var(‘p’) ) {
return get_permalink(get_query_var(‘p’));
}

I know this is not the best code but so far it does what i needed.

I’m not good at php but i believe there is some bug in this file

on line 69 is_singular() returns false which is not right. Also even if we enter that if clause and we find the proper post to display we still continue with the rest if the function.

Anyway if someone of the devs reads this form they may want to take a look.

Best regards,
Stefan Batanov
