I dont know how I missed out on that while looking for aproaches, but I have a working solution now based on this answer. I modified it to check for slashes in $query->request, if there is none I first look for my custom post type (get_posts() with’slug’ => $query->request). If no post is found I … Read more
There’s been a misunderstanding of what query vars actually are and what they’re used for. The correct way to read a URL parameter is the same way as every other PHP application: $mc_id = $_GET[‘mc_cid’]; This is because query vars are not URL parameters! WordPress doesn’t have a special way to retrieve URL parameters, it … Read more
How do I defeat the default action of a query variable on home page redirects to posts page
passing vars to pages in wordpress 6 and search them
There are some fundamental misunderstandings happening here, but importantly: The variables on the main query are what are used to decide which conditionals are true. E.g. will is_home return true, is is_search true? It does this by inspecting the query variables. It’s these conditionals and variables that are then used to decide which template should … Read more
Changing the add_rewrite_rule did the trick: add_rewrite_rule(‘^periodicals/([^/]+)-‘.$tlv[‘code’].'[/]?$’, ‘index.php?periodicals=$matches[1]&post_type=periodicals&name=$matches[1]&mlang=’.$tlv[‘code’], ‘top’); So, I assume for custom post types, using add_rewrite_rule with index.php as query need some extra query variables. A sample will be as: add_rewrite_rule(‘^<custom_post_type>/([^/]+)-‘.$tlv[‘code’].'[/]?$’, ‘index.php?<custom_post_type>=$matches[1]&post_type=<custom_post_type>&name=$matches[1]&mlang=’.$tlv[‘code’], ‘top’);
Because they do different things and source their data from different places. $_GET is for URL parameters, values passed via HTTP GET. get_query_var is for fetching the query variables of the main post query aka the WP_Query object. Query variables and GET values are not the same thing. Query variables usually get their values either … Read more
Make sure that the page template is applied to the correct page and you are accessing the correct URL and then go to the Settings > Permalink and save permalinks one or two times. That should clear the older rewrite rules and make the new page template work instead of sending you to the 404 … Read more
I think the issue may be that you think query_vars can pick up the query string arguments from a URL, but you don’t need to do it that way. That’s primarily used if you’re needing to get this into the WP Query (which isn’t what you’re doing here). It’s much easier to simply check for … Read more
It’s not understandable for me, but the second definition works now. No idea, why it didn’t work before, but I guess, somewhere I made a small mistake. Sorry, for my useless post 😉
