一、去除wordpress头部冗余代码
添加到模版functions.php文件头
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | //去除头部冗余代码 remove_action('wp_head', 'feed_links_extra', 3); remove_action('wp_head', 'feed_links', 2); remove_action('wp_head', 'rsd_link'); //移除离线编辑器开放接口 remove_action('wp_head', 'wlwmanifest_link'); //移除离线编辑器开放接口 remove_action('wp_head', 'index_rel_link'); //本页链接 remove_action('wp_head', 'parent_post_rel_link'); //清除前后文信息 remove_action('wp_head', 'adjacent_posts_rel_link_wp_head'); remove_action('wp_head', 'rel_canonical'); //本页链接 remove_action('wp_head', 'wp_generator'); //移除WordPress版本号 remove_action('wp_head', 'wp_shortlink_wp_head'); //本页短链接 remove_action( 'template_redirect','wp_shortlink_header', 11, 0); add_filter('xmlrpc_enabled', '__return_false'); add_filter('embed_oembed_discover', '__return_false'); remove_action('wp_head', 'wp_oembed_add_discovery_links'); remove_action('wp_head', 'wp_oembed_add_host_js'); remove_filter('pre_oembed_result', 'wp_filter_pre_oembed_result', 10); // 屏蔽 REST API add_filter('rest_enabled', '__return_false'); add_filter('rest_jsonp_enabled', '__return_false'); // 移除头部 wp-json 标签和 HTTP header 中的 link remove_action('wp_head', 'rest_output_link_wp_head', 10); remove_action( 'template_redirect','rest_output_link_header', 11, 0 );//屏蔽WP自带API产生的头部信息 //清除wp_footer带入的embed.min.js function git_deregister_embed_script() { wp_deregister_script('wp-embed'); } add_action('wp_footer', 'git_deregister_embed_script'); add_action( 'wp_enqueue_scripts', 'mt_enqueue_scripts', 1 ); function mt_enqueue_scripts() { wp_deregister_script('jquery'); } |
二、替换文章内链接
添加到模版functions.php文件中
网上教程基本上都是操作数据库替换域名，这样的操作对于“小白”来说有一定的风险。
1 2 3 4 5 6 7 8 9 10 | function replace_text_wps($text){ $replace = array( 'http://baidu.com' => 'http://www.baidu.com',//旧域名=>新域名，可以添加多个，按照格式每行添加一个 'http://old_domain' => 'http://new_domain', ); $text = str_replace(array_keys($replace), $replace, $text); return $text; } add_filter('the_content', 'replace_text_wps'); add_filter('the_excerpt', 'replace_text_wps'); |
三、禁止使用Gutenberg块编辑器并恢复到经典编辑器
添加到模版functions.php文件中
1 2 3 4 5 6 7 8 9 10 11 12 | /** * WordPress完美禁止使用Gutenberg块编辑器并恢复到经典编辑器 - 龙笑天下 * https://www.ilxtx.com/how-to-disable-gutenberg-block-editor.html */ // WP >= 5.0 正式集成Gutenberg古腾堡编辑器 if ( version_compare( get_bloginfo('version'), '5.0', '>=' ) ) { add_filter('use_block_editor_for_post', '__return_false'); // 切换回之前的编辑器 remove_action( 'wp_enqueue_scripts', 'wp_common_block_scripts_and_styles' ); // 禁止前端加载样式文件 }else{ // 4.9.8 < WP < 5.0 插件形式集成Gutenberg古腾堡编辑器 add_filter('gutenberg_can_edit_post_type', '__return_false'); } |
其它优化
添加到模版functions.php文件中
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | //删除文章时删除图片附件 function delete_post_and_attachments($post_ID) { global $wpdb; //删除特色图片 $thumbnails = $wpdb->get_results( "SELECT * FROM $wpdb->postmeta WHERE meta_key = '_thumbnail_id' AND post_id = $post_ID" ); foreach ( $thumbnails as $thumbnail ) { wp_delete_attachment( $thumbnail->meta_value, true ); } //删除图片附件 $attachments = $wpdb->get_results( "SELECT * FROM $wpdb->posts WHERE post_parent = $post_ID AND post_type = 'attachment'" ); foreach ( $attachments as $attachment ) { wp_delete_attachment( $attachment->ID, true ); } $wpdb->query( "DELETE FROM $wpdb->postmeta WHERE meta_key = '_thumbnail_id' AND post_id = $post_ID" ); } add_action('before_delete_post', 'delete_post_and_attachments'); //彻底禁止WordPress缩略图 add_filter( 'add_image_size', create_function( '', 'return 1;' ) ); |

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | /** * WordPress 自动为文章添加已使用过的标签(文章内容版本） */ add_action('save_post', 'auto_add_tags'); function auto_add_tags(){ $tags = get_tags( array('hide_empty' => false) ); $post_id = get_the_ID(); $post_content = get_post($post_id)->post_content; if ($tags) { foreach ( $tags as $tag ) { // 如果文章内容出现了已使用过的标签，自动添加这些标签 if ( strpos($post_content, $tag->name) !== false) wp_set_post_tags( $post_id, $tag->name, true ); } } } |

1 2 3 4 5 | //禁止加载默认jq库 function my_enqueue_scripts() { wp_deregister_script('jquery'); } add_action( 'wp_enqueue_scripts', 'my_enqueue_scripts', 1 ); |
1 2 | // 删掉自动草稿和修订版 $wpdb->query("DELETE FROM `$wpdb->posts` WHERE `post_status` = 'auto-draft' OR `post_type` = 'revision'"); |
