Question

我已经获得了Relevanssi支持人员的下面代码，但我需要针对多站点设置进行调整。

第一段代码是我发送的内容的原件，我保证可以正常工作;第二块代码是我尝试转换为多站点使用的原因。

问题是我无法上班！两者都导致索引跳过所有帖子，但我需要检查我的多站点设置是否正确，因为我对这些查询不太熟悉......

add_filter( 'relevanssi_indexing_restriction', 'rlv_hidden_cats' );
function rlv_hidden_cats( $restriction ) {
    global $wpdb;
    $restriction .= " AND post.ID NOT IN (SELECT object_id FROM $wpdb->term_relationships AS tr, $wpdb->term_taxonomy AS tt WHERE tr.term_taxonomy_id = tt.term_taxonomy_id AND tt.parent NOT IN (13, 14, 15)) ";
    return $restriction;
}

...

add_filter( 'relevanssi_indexing_restriction', 'rlv_hidden_cats' );
function rlv_hidden_cats( $restriction ) {
    global $wpdb;
    $restriction .= " AND post.ID NOT IN (SELECT object_id FROM $wpdb->prefix->term_relationships AS tr, $wpdb->prefix->term_taxonomy AS tt WHERE tr.term_taxonomy_id = tt.term_taxonomy_id AND tt.parent NOT IN (13)) ";
    return $restriction;
}

我的更改发生在＆＃34; $ restriction＆＃34;线

对于多站点，如果它不是根网站，您可以使用$wpdb->get_blog_prefix($blog_id)

获取前缀

然后，你可以做

$base_prefix = $wpdb->get_blog_prefix($123);
$restriction .= " AND post.ID NOT IN (SELECT object_id FROM {$base_prefix}term_relationships AS tr, {$base_prefix}term_taxonomy AS tt WHERE tr.term_taxonomy_id = tt.term_taxonomy_id AND tt.parent NOT IN (13, 14, 15)) ";

如果是根网站，您可以使用$wpdb->base_prefix。

$restriction .= " AND post.ID NOT IN (SELECT object_id FROM {$wpdb->base_prefix}term_relationships AS tr, {$wpdb->base_prefix}term_taxonomy AS tt WHERE tr.term_taxonomy_id = tt.term_taxonomy_id AND tt.parent NOT IN (13, 14, 15)) ";

如果它是多站点的当前网站：

$restriction .= " AND post.ID NOT IN (SELECT object_id FROM {$wpdb->prefix}term_relationships AS tr, {$wpdb->prefix}term_taxonomy AS tt WHERE tr.term_taxonomy_id = tt.term_taxonomy_id AND tt.parent NOT IN (13, 14, 15)) ";

P.S。 $wpdb->prefix和$wpdb->base_prefix是字符串，您不能$wpdb->prefix->term_relationships。但是，您可以执行类似$wpdb->term_relationships的操作，它将为您提供表term_relationships的全名（例如，如果前缀为wp_，则您将获得wp_term_relationships）

wordpress $ wpdb-＆gt;前缀不起作用
