早些时候,追格小编分享过《教你怎么删除WordPress默认的未分类》,今天再分享一个新方法,直接用代码搞定。


不用代码的话,用前面说的这个方法就好,相对比较简单。Category删不删除其实并没什么影响,只是有些同学看着难受罢了。


代码删除方法:


将下面代码添加到当前WordPress模板函数functions.php中即可。


    add_action('load-themes.php', 'no_category_base_refresh_rules');
    add_action('created_category', 'no_category_base_refresh_rules');
    add_action('edited_category', 'no_category_base_refresh_rules');
    add_action('delete_category', 'no_category_base_refresh_rules');

function no_category_base_refresh_rules() {
    global $wp_rewrite;
    $wp_rewrite->flush_rules();
}
// Remove category base
add_action('init', 'no_category_base_permastruct');
function no_category_base_permastruct() {
    global $wp_rewrite, $wp_version;
    if (version_compare($wp_version, '3.4', '<')) {
    } else {
        $wp_rewrite->extra_permastructs['category']['struct'] = '%category%';
    }
}
// Add our custom category rewrite rules
add_filter('category_rewrite_rules', 'no_category_base_rewrite_rules');
function no_category_base_rewrite_rules($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 $category_rewrite;
}
// Add 'category_redirect' query variable
add_filter('query_vars', 'no_category_base_query_vars');
function no_category_base_query_vars($public_query_vars) {
    $public_query_vars[] = 'category_redirect';
    return $public_query_vars;
}
// Redirect if 'category_redirect' is set
add_filter('request', 'no_category_base_request');
function no_category_base_request($query_vars) {
    //print_r($query_vars); // For Debugging
    if (isset($query_vars['category_redirect'])) {
        $catlink = trailingslashit(home_url()) . user_trailingslashit($query_vars['category_redirect'], 'category');
        status_header(301);
        header("Location: $catlink");
        exit();
    }
    return $query_vars;
}
