Currently, I have two categories to separate my WordPress blog posts.
- site.com/category/slow/
- site.com/category/fast/
As you can see, my site's category base is 'category'.
My permalink settings on the Dashboard under Settings->Permalinks is set to "site.com/%postname%/".
This means that all my blog posts will appear like this: "site.com/post-title/" regardless of which category I assign the post to.
The thing is, I want to remove the category base from the URL so that they become:
- site.com/slow/
- site.com/fast/
And at the same time, without altering the permalink setting so that my blog posts' URL continue to look like "site.com/post-title/". How can I achieve these?
Here's the solution after I modified a bit the code I found:
// Remove category base
function no_category_base_permastruct() {
global $wp_rewrite;
$wp_rewrite -> extra_permastructs['category']['struct'] = '%category%';
}
add_action('init', 'no_category_base_permastruct');
// Add our custom category rewrite rules
function no_category_base_rewrite_rules($category_rewrite) {
//var_dump($category_rewrite); // For Debugging
$category_rewrite = array();
$categories = get_categories(array('hide_empty' => false));
foreach ($categories as $category) {
$category_nicename = $category -> slug;
if ($category -> parent == $category -> cat_ID)// recursive recursion
$category -> parent = 0;
elseif ($category -> parent != 0)
$category_nicename = get_category_parents($category -> parent, false, '/', true) . $category_nicename;
$category_rewrite['(' . $category_nicename . ')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
$category_rewrite['(' . $category_nicename . ')/page/?([0-9]{1,})/?$'] = 'index.php?category_name=$matches[1]&paged=$matches[2]';
$category_rewrite['(' . $category_nicename . ')/?$'] = 'index.php?category_name=$matches[1]';
}
// Redirect support from Old Category Base
global $wp_rewrite;
$old_category_base = get_option('category_base') ? get_option('category_base') : 'category';
$old_category_base = trim($old_category_base, '/');
$category_rewrite[$old_category_base . '/(.*)$'] = 'index.php?category_redirect=$matches[1]';
//var_dump($category_rewrite); // For Debugging
return $category_rewrite;
}
add_filter('category_rewrite_rules', 'no_category_base_rewrite_rules');
// Add 'category_redirect' query variable
function no_category_base_query_vars($public_query_vars) {
$public_query_vars[] = 'category_redirect';
return $public_query_vars;
}
add_filter('query_vars', 'no_category_base_query_vars');
// Redirect if 'category_redirect' is set
function no_category_base_request($query_vars) {
//print_r($query_vars); // For Debugging
if (isset($query_vars['category_redirect'])) {
$catlink = trailingslashit(get_option('home')) . user_trailingslashit($query_vars['category_redirect'], 'category');
status_header(301);
header("Location: $catlink");
exit();
}
return $query_vars;
}
add_filter('request', 'no_category_base_request');
