Bulk adding location rules for Content template elements

Hi there,

It’s not possible from the UI, but you can use the generate_hook_element_display filter.

There is an example of usage in this article:
https://docs.generatepress.com/article/generate_hook_element_display/

Hi there,

I need a little more info.
How do each of the 3 content templates relate to their pages ?

For example in posts, it would be as simple as having Post Categories to set the location.
How does that compare to this requirement ?

OK. Tricky one.
We could build a function that determines if a page is a top level, a child, or a grandparent:

function get_page_hierarchy_level($page_id = null) {
    if (is_null($page_id)) {
        $page_id = get_the_ID();
    }
    $ancestors = get_post_ancestors($page_id);
    if (empty($ancestors)) {
        return 'top-level';
    }
    if (count($ancestors) == 1) {
        return 'child';
    }
    if (count($ancestors) == 2) {
        return 'grandchild';
    }
    return null;
}

Then you could use that function within the generate_element_display hook like so:

add_filter( 'generate_hook_element_display', function( $display, $element_id ) {
    // get the page hierarchy level
    $level = get_page_hierarchy_level();
    // check if top-level, child or grnadchild
    if ( 
        123 === $element_id && 'top-level' === $level ||
        456 === $element_id && 'child' === $level ||
        789 === $element_id && 'grandchild' === $level         
    ) { 
        $display = true; 
    } 
    return $display; 
}, 10, 2 );

Here we grab the $level and for each of the three element IDs ( update your element IDs ) we check its level and tell the element to display.

This however will apply to all pages… so it may need some extra conditions to narrow that down

It would. If you don’t mind having a large array of numbers 🙂

Can you show us the exact code you are using and wrap the code with the code tag?

Let me know 🙂

Try replacing generate_hook_element_display with generate_element_display.

For #1 under Display Rules – Location … this should be left blank ie ‘choose’?

Blank.

Not sure what you mean by hook: wp_body_open, if it’s a content template block element, then there isn’t a hook option. Let me know if I miss anything!

Can you remove global $post;?

And how did you add the code? Via Code snippets plugin or child theme functions.php?

The snippet is not supposed to be added into the Hook Element; you need to use a Code Snippet plugin for that.

Then delete the Hook Element you used to add the snippet, as it’s no longer required. The filter to use is generate_element_display.
