I created a page called Catalog and also a template called page-catalog.php. The url looks like this now: sitename.com/catalog

So far so good, however i use some custom php stuff to list products from another database. So when i click on a brand in this page, i want to use an url like this: sitename.com/catalog/brands/brandname

But obviously because the data is not coming from Wordpress, it gives me 404. Is it possible to use the same page-catalog.php file if the url has more parts?

I could use an url like this: sitename.com/catalog/?brand=brandname But this solution is not so sep friendly.

  • Your question really isn't about disabling the 404 page, as it is about how to combine external DB data with WordPress data. May 24, 2012 at 16:07

You could use a WordPress rewrite (as opposed to mod-rewrite) to solve the issue.

function createRewriteRules( $rules ){
    $newrules = null;
    $newrules = array();
    $newrules["catalog/?$"] = "index.php?page=xx";
    $rules = $newrules + $rules;
    return $rules;

add_action('rewrite_rules_array', 'createRewriteRules');

You'll need to flush the rules:


Your page-catalog.php file could then sniff the original url and do some processing as required.

  • Thanks, i just tried it, but it's not working. .com/catalog loads up my index.php, .com/catalog/anything gives me 404.php

  • Did you flush the rules? (A quick way is in WP Admin, change your permalink structure to something different, save, and then change it back and save).

  • Also, try with the function in a plugin as opposed to functions.php

  • Yes, that was the problem, thanks! Maybe i can mess with the add_action location, like add_action=init to make this work from the functions.php

  • It's most likely that functions.php doesn't work because it loads fairly late in the bootstrap process, loading the rewrite rules too late may have other unintended consquences - they're used to determine a bunch of things, most importantly what template to load.
