php - WordPress 插件数据库错误 您的 SQL 语法有错误

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 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 6 行的 'AND p.post_status='publish'' 附近用于查询 SELECT count(*) FROM wp_posts p

的正确语法

    [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

我认为它会导致 GeoMashup 的“geo-mashup-db.php”的一部分(复制如下)，并且我已经阅读了一些有关 ID/id 之间的大写/小写不匹配的内容，这可能会导致此问题，但我可以似乎没有找到任何这样的例子。任何帮助或建议都会很棒。

*
* @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，但就其值(value)而言:问题在于 Geo Mashup 的小部件选项，该选项“自动”为类别创建 map 链接(管理 >“模糊设置”)。

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

取消选中将 map 链接添加到类别列表将停止错误。
按名称/ID 映射类别的短代码和模板标签仍然可以正常工作。

希望这可以帮助别人。
