Can I have single digit wordpress permalinks? Trying to force the permalink to "2" e.g. automatically rewrites it to "2-2".
Looking into it a bit further I discovered this is the case for any numerical permalink - I reckon it has to do with possible interference with paging but have a use case where I would like to use this structure..

I've dealt with this once by intercepting the post slug creation and "fixing" it somehow. Maybe you can work from this:
/*
* New permalink structure
*
* Itercepts every wp_insert_post data to change the regular slugs to md5 hashes
* based on the Unix timestamp of action. This generates a new slug at every
* saving action, which protects the posts against unauthorised direct access.
*
*/
function rm_cpt_permalink_change($data) {
if ($data['post_type'] == 'custom_post_type') {
$time = time();
$data['post_name'] = md5($time);
return $data;
} else {
return $data;
}
}
add_filter('wp_insert_post_data','rm_cpt_permalink_change',10,2);
Do you really need single-digit slugs? If you can have your way with 00001 or 000005, the wp_insert_post_data filter is probably the way to go.
回答2:
actually this can be easily done from the permalinks section in the settings. You can simply set /post_id/ as the permalink structure and it will work fine.
回答3:
You probably already have a post with the slug '2'; if it's not in the post administration panel, it might still be in the trash.
On a side note, using digits as slugs might not be the best idea--it could conflict with paging and other rewrite rules, and might not describe what that post is for.
Hope this helps!
