前言

筛选针对自定义字段的日期选择器筛选生成的 meta_query。允许你针对特定字段自定义日期比较的处理方式（例如日期格式、范围逻辑）。

用法

将代码加入子主题的 functions.php：

add_filter( 'bricks/query_filters/datepicker_custom_field_meta_query', function( $meta_query, $filter, $provider, $query_id ) {
    // Example: Change type to 'NUMERIC' for timestamp fields stored as numbers
    if ( $filter['settings']['fieldName'] === 'my_timestamp_field' ) {
        if ( isset( $meta_query['type'] ) ) {
            $meta_query['type'] = 'NUMERIC';
        } elseif ( isset( $meta_query[0] ) ) {
            // Handle range query (array of arrays)
            foreach ( $meta_query as $key => $clause ) {
                if ( is_int( $key ) ) {
                    $meta_query[ $key ]['type'] = 'NUMERIC';
                }
            }
        }
    }


    return $meta_query;
}, 10, 4 );

参数

$meta_query (array)：已生成的 meta_query 数组（例如 [‘key’ => ‘…’, ‘value’ => ‘…’, ‘type’ => ‘DATE’]）。
$filter (array)：激活的筛选数据，包括设置和已解析日期。
$provider (string)：数据 provider（例如 acf、metabox）。
$query_id (string)：正在被筛选的查询循环 ID。

示例代码

筛选返回值

add_filter( 'bricks/query_filters/datepicker_custom_field_meta_query', function( $meta_query, $filter, $provider, $query_id ) {
    // Example: Change type to 'NUMERIC' for timestamp fields stored as numbers
    if ( $filter['settings']['fieldName'] === 'my_timestamp_field' ) {
        if ( isset( $meta_query['type'] ) ) {
            $meta_query['type'] = 'NUMERIC';
        } elseif ( isset( $meta_query[0] ) ) {
            // Handle range query (array of arrays)
            foreach ( $meta_query as $key => $clause ) {
                if ( is_int( $key ) ) {
                    $meta_query[ $key ]['type'] = 'NUMERIC';
                }
            }
        }
    }


    return $meta_query;
}, 10, 4 );

根据条件短路返回原值

根据条件跳过或修改返回值：

add_filter( 'bricks/query_filters/datepicker_custom_field_meta_query', function( $value, $meta_query ) {
    if ( is_admin() ) { return $value; }
    // TODO: custom logic here
    return $value;
} );
