折腾wordPress/ target=_blank class=infotextkey>WordPress的朋友都知道修改固定链接后,在分类链接中会出现一个/category/目录,为了去掉分类链接中category目录,网上出现了各种去除category目录的类似插件,比如WP No category Base 插件。
今天小编手把手教你不用插件来实现WordPress去掉分类链接中category目录,只需要将下面代码添加到你当前主题的 functions.php 文件中即可:
PS:代码太长 - - 下载地址:No category Base 也可以打开下面的隐藏代码直接复制你当前主题的functions.php 文件中:
//去除分类标志代码 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', '<')) { // For pre-3.4 support $wp_rewrite -> extra_permastructs['category'][0] = '%category%'; } 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'])) { $catlink = trailingslashit(get_option('home')) . user_trailingslashit($query_vars['category_redirect'], 'category'); status_header(301); header("Location: $catlink"); exit(); } return $query_vars; }
安装插件或者用代码可能会出现404页面,即%post_id%.html(本站设置的固定链接)的伪静态失效了!
解决方法:
登录后台→设置→固定链接设置页面,随意改一下固定链接格式,然后再改回自己正常用的固定链接格式,可以解决这个bug,不行就反复多改几次。
PS:如果还会出现404,建议把所有缓存清除后再尝试!
