Question

每次加载页面时，我都会多次收到此消息。 [07-Jul-2018 17:30:49 UTC] WordPress数据库错误您的SQL语法错误；检查与您的MySQL服务器版本相对应的手册以获取正确的语法，以在第6行的'AND p.post_status ='publish'附近使用查询SELECT count（*）FROM wp_posts p

    [07-Jul-2018 17:30:49 UTC] WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND p.post_status='publish'' at line 6 for query SELECT count(*) FROM wp_posts p

我认为它导致了GeoMashup的“ geo-mashup-db.php”部分（在下面复制），并且我读了一些有关ID / id之间大小写不匹配的问题，但是我可以似乎找不到任何实例。任何帮助或建议将是巨大的。

* @since 1.2
*
* @param id $category_id
* @return int
*/
public static function category_located_post_count( $category_id ) {
global $wpdb;

$select_string = "SELECT count(*) FROM {$wpdb->posts} p
INNER JOIN {$wpdb->term_relationships} tr ON tr.object_id = p.ID
INNER JOIN {$wpdb->term_taxonomy} tt ON tt.term_taxonomy_id = tr.term_taxonomy_id
INNER JOIN {$wpdb->prefix}geo_mashup_location_relationships gmlr ON gmlr.object_id = p.ID AND gmlr.object_name = 'post'
WHERE tt.term_id = " . esc_sql( $category_id ) ."
AND p.post_status='publish'";
return $wpdb->get_var( $select_string );
}

/**

*
* Not sufficient - probably want parent categories.
*
* @return array Located category id, name, slug, description, and parent id
*/
private static function get_located_categories() {
global $wpdb;

$select_string = "SELECT DISTINCT t.term_id, t.name, t.slug, tt.description, tt.parent
FROM {$wpdb->prefix}geo_mashup_location_relationships gmlr
INNER JOIN {$wpdb->term_relationships} tr ON tr.object_id = gmlr.object_id
INNER JOIN {$wpdb->term_taxonomy} tt ON tt.term_taxonomy_id = tr.term_taxonomy_id
INNER JOIN {$wpdb->terms} t ON t.term_id = tt.term_id
WHERE tt.taxonomy='category'
ORDER BY t.slug ASC";
return $wpdb->get_results( $select_string );
}

Answer 1

一篇较旧的文章，但值得一提：问题在于Geo Mashup的小部件选项，该选项可“自动”创建类别的地图链接（管理员>“模糊设置”）。

所有类别中的所有帖子都必须保存所有GeoMeta（la t，lng，geo-address和已保存的名称），否则您会经常收到此错误。

取消选中Add map links to category lists将停止错误。
按名称/ ID映射类别的简码和模板标签仍然可以正常工作。

希望这可以帮助某人。
