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。

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

/** * 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'); } |
