How to set an Element location to Child of a Parent Page
3 replies · Started by Tim on April 18, 2020
Hello
Previously I have created custom fields for posts with ACF setting their location as:
"Post Category" "is equal to" "CategoryName".
I am then able to create an Element hook to Display Location as:
"Post Category" "is equal to" "CategoryName".
Good.
However, with Pages I create custom fields where "Page Parent" "is equal to" "ParentPageName".
But I do not see an equivalent Display Location for my hook, only
"Page" "is equal to" "SpecificPageName"
Am I missing an option ?
Hi there,
nope not missing an option - parent relationships are something we are looking into for display rules and maybe a future option. For now it requires a filter like the one shared by this user:

Hi David
Look forward to that page relationships added to Elements.
Thank you for pointing out that thread.
Turns out this post was the one I needed as it includes and array of Parent Pages:

add_filter( 'generate_hook_element_display', function( $display, $element_id ) {
global $post;
if ( $element_id===3106 &&
( is_page(array(1291,1326)) ||
is_page() && $post->post_parent===1291 ||
is_page() && $post->post_parent===1326
)
) {
$display = true;
}
return $display;
}, 10, 2 );What does the }, 10, 2 ); part represent ?
The Priority and the number of arguments
