1、WordPress 网站如何给自带的搜索功能添加过滤只搜索文章的标题？如果想让 WordPress 自带的搜索功能只搜索文章标题，让搜索结果更加精确（其实WordPress 自带的搜索功能本来模糊查找就很弱），可以将下面的代码添加到当前主题functions.php中：
- //只搜索文章标题
- function wpse_11826_search_by_title( $search, $wp_query ) { if ( ! emptyempty( $search ) && ! emptyempty( $wp_query->query_vars[‘search_terms’] ) ) { global $wpdb; $q = $wp_query->query_vars; $n = ! emptyempty( $q[‘exact’] ) ? ” : ‘%’; $search = array(); foreach ( ( array ) $q[‘search_terms’] as $term ) $search[] = $wpdb->prepare( “$wpdb->posts.post_title LIKE %s”, $n . $wpdb->esc_like( $term ) . $n ); if ( ! is_user_logged_in() ) $search[] = “$wpdb->posts.post_password = ””; $search = ‘ AND ‘ . implode( ‘ AND ‘, $search ); } return $search;}add_filter( ‘posts_search’, ‘wpse_11826_search_by_title’, 10, 2 );
