使用wordpress中的自定义SQL查询通过wp_get_nav_menu_items提高wp_posts中的查询性能 _WordPress主题

今天, 我遇到了一个问题, 该问题显着降低了网站的性能。在我的标题中, 菜单类别已加载(菜单名称-> header_nav)。我用wp_get_nav_menu_items($ menu-> term_id)之类的函数加载它们。此函数返回一个对象数组, 其中有很多字段, 因为有很多类别, 所以也有很多对象。从整个对象来看, 我只需要$ object-> 标题, $ object-> 链接, $ object-> id。我需要从多语言标题中获取此数据。

//$menu_items too large array of objects$menu = wp_get_nav_menu_object( $locations[ 'menu_slug'] ); //Here my array. do foreach and creating category menu using //$menu_item-> title...and etc. $menu_items = wp_get_nav_menu_items($menu-> term_id);

我决定写自己的请求。但是它返回的数据没有多语言

SELECT p2.ID, p2.post_title, p2.post_name, p2.guid, p1.post_parent FROM wp_posts p1 INNER JOIN wp_term_relationships AS TR ON TR.object_id = p1.ID INNER JOIN wp_postmeta AS pm ON pm.post_id = p1.ID INNER JOIN wp_posts AS p2 ON p2.ID = pm.meta_value WHERE p1.post_type = 'nav_menu_item' AND TR.term_taxonomy_id = $taxId AND pm.meta_key = '_menu_item_object_id' ORDER BY p1.menu_order ASC

如何返回已经翻译的标题？

SELECT * FROM wp_posts p1 INNER JOIN wp_term_relationships AS TR ON TR.object_id = p1.ID INNER JOIN wp_postmeta AS PM ON pm.post_id = p1.ID INNER JOIN wp_posts AS p2 ON p2.ID = PM.meta_value WHERE p1.post_type = 'nav_menu_item' AND TR.term_taxonomy_id = ( SELECT wp_terms.term_id FROM wp_terms WHERE slug = 'pedik') AND pm.meta_key = '_menu_item_object_id' ORDER BY p1.menu_order ASC

标题

$menu_item-> object_id = ! isset( $menu_item-> object_id ) ? get_post_meta( $menu_item- > ID, '_menu_item_object_id', true ) : $menu_item-> object_id;

$menu_item-> url = get_permalink( $menu_item-> object_id );

标题

$original_title = apply_filters( 'the_title', $original_object- > post_title, $original_object-> ID ); if ( '' === $original_title ) { /* translators: %d: ID of a post */ $original_title = sprintf( __( '#%d (no title)' ), $original_object- > ID ); }$menu_item-> title = '' == $menu_item-> post_title ? $original_title : $menu_item-> post_title;
