Display rules for elements : regex possible?

Hi there,

You can use this filter for advanced display rules:
https://docs.generatepress.com/article/generate_element_display/

You will need to find the correct conditional tag to use which is not related to the theme:

Hope this helps :)

Hi Leo,

Thank you, this solution seems to answer my need, but but it doesn't work. Did I misunderstand something?

At the end of the function.php file in my child theme I added :

add_filter( 'generate_element_display', function( $display, $element_id ) {
    global $post;

    if ( 5281 === $element_id && ( is_page() && $post->post_parent == '3854' ) ) {
        $display = true;
    }

    return $display;
}, 10, 2 );

5281 : My Element ID
3854 : My parent page ID (/directory1/ in my previous example)

Thank you in advance

Hi there,

what happens if you flip it on its head, and set the Element Display rules to display on ALL pages, and set a negative condition to make it false:

if ( 5281 === $element_id && !( is_page() && $post->post_parent == '3854' ) ) {
    $display = false;
}

Hi David,

I tried :
- I chose "All website" as display rule
- I set a negative condition :

add_filter( 'generate_element_display', function( $display, $element_id ) {
    global $post;

if ( 5281 === $element_id && !( is_page() && $post->post_parent == '3854' ) ) {
    $display = false;
}

    return $display;
}, 10, 2 );

>> The function don't working because my header is displayed on all pages

Hi Maxime,

When using this PHP snippet, can you make sure the location of the element is set to blank?

add_filter( 'generate_element_display', function( $display, $element_id ) {
    global $post;

    if ( 5281 === $element_id && ( is_page() && $post->post_parent == '3854' ) ) {
        $display = true;
    }

    return $display;
}, 10, 2 );

Hi Ying,

Yes I tried to setting empty or pick other elements (all websites, pages...). but nothing change.

I tested Yings latest version, with the Block Elements display rules set to 'blank' and it worked.

Can you double check the ID of the Element and the Post Parent ?

I double checked The IDs and I tried with another page and another element(with the corresponding IDs), but no change.

When I Publish/Update my element, I have the followgin message : https://ibb.co/C11Sgbb
Could this be an indication regarding this issue?

Ah I see, header element doesn't allow publish without location.

Can you try using block element?

I tried with a "block" type Element but it still doesn't work : https://ibb.co/GsdrBND

if it's easier for you, I can give you a temporary access to the website. Let me know.

Send us a temporary admin login and we can take a look.
You can share the login details in the Private Information field.

Thank you, I shared the access

Ok - first thing i notice is the GP Premium version is only 1.12 - which is really out of data and the generate_element_display filter wasn't added until version 2.0.

Is it possible to update the plugin ?

Oh yes,I updated the plugin with the version 2.1.2
