WordPress默认的搜索功能,使用户搜索结果包括文章内容、文章标题与文章标签 这样搜索出来的结果不会很精确,如果你想让它搜索出来的结果更精确、相关,可以限定只搜索文章的标题。
将下面的代码添加到主题的 functions.php 文件即可实现:
//让WordPress只搜索文章的标题
function __search_by_title_only( $search, &$wp_query )
{
global $wpdb;
if ( empty( $search ) )
return $search; // skip processing - no search term in query
$q = $wp_query->query_vars;
$n = ! empty( $q[\\\'exact\\\'] ) ? \\\'\\\' : \\\'%\\\';
$search =
$searchand = \\\'\\\';
foreach ( (array) $q[\\\'search_terms\\\'] as $term ) {
$term = esc_sql( like_escape( $term ) );
$search .= \\\"{$searchand}($wpdb->posts.post_title LIKE \\\'{$n}{$term}{$n}\\\')\\\";
$searchand = \\\' AND \\\';
}
if ( ! empty( $search ) ) {
$search = \\\" AND ({$search}) \\\";
if ( ! is_user_logged_in() )
$search .= \\\" AND ($wpdb->posts.post_password = \\\'\\\') \\\";
}
return $search;
}
add_filter( \\\'posts_search\\\', \\\'__search_by_title_only\\\', 500, 2 );
