[Plugin: wp-category-archive] Broken in WP 3.1

To get the plugin to work with permalinks in WP3.1, you need to update the redirect_canonical() function in wp-includes/canonical.php. On line 167 wrap the following code:

$tax_url = parse_url($tax_url);
if ( ! empty($tax_url['query']) ) { // Custom taxonomies may only be accessable via ?taxonomy=..&term=..
    parse_str($tax_url['query'], $query_vars);
    $redirect['query'] = add_query_arg($query_vars, $redirect['query']);
} else { // Taxonomy is accessable via a "pretty-URL"
    $redirect['path'] = $tax_url['path'];
}

in an if (is_tax()) block:

if (is_tax()) {
    $tax_url = parse_url($tax_url);
    if ( ! empty($tax_url['query']) ) { // Custom taxonomies may only be accessable via ?taxonomy=..&term=..
        parse_str($tax_url['query'], $query_vars);
        $redirect['query'] = add_query_arg($query_vars, $redirect['query']);
    } else { // Taxonomy is accessable via a "pretty-URL"
        $redirect['path'] = $tax_url['path'];
    }
}

I am not sure how the plugin can be updated to get around the WP3.1 problem where with permalinks on, the date and category URL does not show a page of posts for the particular date and category.

/category-label/2011/04

If someone can come up with a URL that shows posts for a particular category and date with permalinks set in WP3.1, we can update the plugin to use that URL pattern.

We could also create a forum post about the date and category page not working with permalinks in WP3.1.

Hi Hugh,

Thanks for getting back to me. I agree, I think this is something the WP team should change in their canonical function you mentioned – frustrating how they change the core in such a way that plugin developers are cornered with their development.

Do you think there’s a way of doing this by creating a function in functions.php? At least that way, the core edit could be kept within the theme folder.

I agree that posting in the forums about the date and category pages not working 3.1 would be a good idea – do you want to do it, or should I? You’ll probably have more ‘authority’ on the issue considering you know more about it than me!

Thanks

Just checked, seems to be working correctly in WP 3.1.1.
