[Author]

Hi!
I have a view with a parametric search for "evento-corso" post type
evento corso is child of crystal-nails-corsi

I'd like to filter by a field "livello" id="$crystal-nails-corsi"

I've tried this but it doesn't work

 [wpv-control field="livello"  id="$crystal-nails-corsi" url_param="livello" type="select" auto_fill_default="cerca" auto_fill="wpcf-livello" auto_fill_sort="asc"]

The result is no item found

At the same time in the Output template of this view I can see correctly

 Livello:[types field="livello" id="$crystal-nails-corsi"][/types]

Can you help me?

Thank you! Alba 🙂

Hello. Thank you for contacting the Toolset support.

As I understand you want to filter your post by specific parent custom field [types field="livello" id="$crystal-nails-corsi"][/types].

You can pass argument of your parent field to child view and filter the child view with views shortcode argument. :
For example:

[wpv-view name="Child view - listing training posts" child_of="[wpv-post-id]"]

Hi! 🙂
Can you write me the exat way to insert that shortcode in my code?

- This view is for evento-corso
- that is child of crystal-nails-corsi
- LIVELLO is a field of crystal-nails-corsi

[wpv-filter-controls]

[wpml-string context="wpv-views"]<label>Difficoltà:</label>[/wpml-string][wpv-control field="livello"  url_param="livello" type="select" auto_fill_default="cerca" auto_fill="LIVELLO" auto_fill_sort="asc"]

  
[wpv-filter-submit name="Cerca il tuo Corso" type="input"]  

[wpv-filter-reset reset_label="Azzera la ricerca" type="input"]
[/wpv-filter-controls]

Thank you so much!

Sorry but I'm bit confuse here - could you please explain me what exactly you want to display and what are the filters you want to have - a dummy test case will be helpful to understand your requirement.

[filippoi]

Ok i'll try to explain better 🙂

For example:

I have a custom post type "Events" that is child of "courses" and "locations"
courses+locations+date (the only field that belongs to Events) =events

I have a view with a parametric search that is applied to "Events"

I'd like to filter by the field "province" that belongs to "locations"

I don't know how to write in the search that "province" belongs to "locations"

i'd like to have as result the list of all the events for the selected province

Thanks!! 🙂

You need to create parent/child views.

1)
- Create a view "Events-child"
- "Content Selection" section select CPT "Events"
- "Query Filter" section add:

Post relationship filter
Select posts that are a children of the Post set by parent View.

- Loop output section, add post link, for example:

[wpv-layout-start]
	[wpv-items-found]
	<!-- wpv-loop-start -->
		<wpv-loop>
          [wpv-post-link]
		</wpv-loop>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
[wpv-layout-end]

- save your view

2)
- Create a view "locations-parent"
- "Content Selection" section select CPT "Location"
- "Filter" section add field "province", for example

[wpml-string context="wpv-views"]province:[/wpml-string] [wpv-control field="province" url_param="province" type="select" auto_fill_default="Please select" auto_fill="wpcf-province" auto_fill_sort="asc"]

- Loop output section, add child view "Events-child", for example:

[wpv-layout-start]
	[wpv-items-found]
	<!-- wpv-loop-start -->
	<ul class="wpv-loop js-wpv-loop">
		<wpv-loop>
			[wpv-view name="child-view-pr-events"]
		</wpv-loop>
	</ul>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
	[wpv-no-items-found]
		<strong>[wpml-string context="wpv-views"]No items found[/wpml-string]</strong>
	[/wpv-no-items-found]
[wpv-layout-end]

-save your view

3)
Add your parent view "locations-parent" to your page and you will have results you are looking for.
