Hi,
The pagination and search results are both set to update through AJAX (i.e. without a page reload) and in such a case, it is important that the first option in the select type filter attached to a custom field, doesn't contain any value.
To fix this, you can update your shortcode for the "Khoảng giá" field from:
[wpv-control-postmeta values="0-1000000000,1000000001-3000000000,3000000001-5000000000,5000000001-8000000000,8000000001-10000000000,10000000000-100000000000" display_values="Khoảng giá,<1 tỷ,Từ 1 - 3 tỷ,Từ 3 - 5 tỷ,Từ 5 - 8 tỷ,Từ 8 - 10 tỷ,> 10 tỷ" field="wpcf-gia" type="select" source="custom" url_param="wpv-wpcf-gia"]
To
[wpv-control-postmeta values=",0-1000000000,1000000001-3000000000,3000000001-5000000000,5000000001-8000000000,8000000001-10000000000,10000000000-100000000000" display_values="Khoảng giá,<1 tỷ,Từ 1 - 3 tỷ,Từ 3 - 5 tỷ,Từ 5 - 8 tỷ,Từ 8 - 10 tỷ,> 10 tỷ" field="wpcf-gia" type="select" source="custom" url_param="wpv-wpcf-gia"]
And shortcode for the "Phòng ngủ" field from:
[wpv-control-postmeta display_values="Phòng ngủ,1,2,3,4,5" values="1,2,3,4,5" field="wpcf-so-phong-ngu" type="select" source="custom" url_param="wpv-wpcf-so-phong-ngu"]
To:
[wpv-control-postmeta display_values="Phòng ngủ,1,2,3,4,5" values=",1,2,3,4,5" field="wpcf-so-phong-ngu" type="select" source="custom" url_param="wpv-wpcf-so-phong-ngu"]
You'll find the details about the supported attributes of the "wpv-control-postmeta" shortcode at:
https://toolset.com/documentation/user-guides/views-shortcodes/#wpv-control-postmeta
This will ensure that the first label options for these fields don't include any values, which can change the query when pagination is used without changing any search form filter.
Please let me know how it goes and if you need any further assistance around this.
regards.
