These rewrite rules are killing me. It is probable something little, but I can't find it.
I have a custom post type called 'tournament', it's permalink structure looks like
<domain>/<season>/<tournament-name>
For this custom post type everything works fine.
Now I have created a second custom post type 'match'. I set hierarchy to false. I added a meta-box to match where I can select the tournament and store it as post_parent.
Now I want its permalink structure to look like:
<domain>/<season>/<tournament-name>/match/<match-name>
I use the post_type_link hook to add a filter that creates the permalink I want and the init hook to add the rewrite rule. The permalink is created as expected, but when using the rewrite rule, I keep getting 404's.
I flushed the rewrite rules both in code and manually.
I checked the regex and it's valid.
I suspect it is the redirect string, but I'm not sure.
Any suggestions or ideas?
function rat_match_post_type_link( $link, $post, $leavename, $sample ){
if ( $post->post_type == 'match' ){
$parent = get_post($post->post_parent);
$season = get_post_meta( $parent->ID, 'rat-tournament-season', true);
error_log (home_url( $season . '/' . $parent->post_name . '/match/' . $post->post_name));
return home_url( $season . '/' . $parent->post_name . '/match/' . $post->post_name);
} else {
return $link;
}
}
add_filter('post_type_link', 'rat_match_post_type_link', 10, 4);
function rat_match_rewrite_rules()
{
add_rewrite_rule('[0-9]{4}/(.+?)/match/([^/]+)?$','index.php?match=$matches[2]','top');
}
add_action('init', 'rat_match_rewrite_rules');
Note: I know I need to fix the post type link function in case there is no parent.
EDIT (8-feb-2019)
While trying to investigate further I observed the following:
When I access:
/index.php?match=test-match
The result is:
/2019/the-hague-4-star/match/test-match?match=test-match
And the latter results in a 404.
