There are numbers of articles available in Google if you have searched before you posted.
WordPress search only in post title
如果您在发布之前进行了搜索，那么在 Google 中可以找到大量文章。
WordPress 仅在帖子标题中搜索
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) {
$term = esc_sql($wpdb->esc_like($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);
