[Support request] Author box via hook element

[Nadine]

Hello, I have created an author box with Element – Hook and dynamic data. We have multiple authors. However, I want to show this box only for three specific author names. How is that possible? because I haven´t no selection in the display box.

Hi there,

you would need to use a PHP Snippet to disable the Block Element for posts that have different authors.

Try this:

add_filter( 'generate_element_display', function( $display, $element_id ) {

    $author = get_the_author();
    $author_list = array( 'display name', 'another name', 'another name' );
    
    if ( 100 === $element_id && in_array( $author , $author_list ) ) {
        $display = true;
    }

    return $display;

}, 10, 2 );

1. you need to update the array of author display names with the authors who will have the author box here:
$author_list = array( 'display name', 'another name', 'another name' );

2. The 100 is the ID of the Element, swap that for the one found in your Elements URL when editing it.

Thank you for your feedback.

I get a error message about snippet:
syntax error, unexpected token “;”

And what do you mean about topic 1 and 2?

I am really sorry about that, i have updated the code above

Ok in that code there are things you need to change:

1. In this line of the code:
$author_list = array( 'display name', 'another name', 'another name' );

You need to change the values in the array to the display names of your 3 authors.

2. Edit your block element and check the browser URL field and make a not of the ID= value eg.. 55.
In the code above, change this line:

if ( 100 === $element_id && !in_array( $author , $author_list ) ) {

Hello, i´m sorry, but it doesn`t works. I send you two links of two images. That are screenshots of author-box (with URL wp-admin/post.php?post=156224&action=edit) and php-script.
Maybe do you see a mistake because i can always see the box in all blog articles of all authors and not only of this three names.

I made change to the code above:

Hello David,

i took this code again, i changed array field with author names and i replaced again the id number with url-id. But it doesn´t works???
Is it possible, to add a fields in hook-location like blog-author? So that i can select an author name?

[David]

Sorry about this, the author name always messes me up.
Try this snippet:

add_filter( 'generate_element_display', function( $display, $element_id ) {
	
	// list of authors to show element too
	$author_list = array( 'display name', 'another name', 'another name' );
	
	// Get the current post author
	global $post;
	$author_id = get_post_field( 'post_author', get_the_id() );
        $author = get_the_author_meta('display_name', $author_id);
    
        // if author in array the set display to true
	if ( 137 === $element_id && is_single() && !is_admin() && in_array( $author , $author_list ) ) {
            $display = true;
        }

        return $display;

}, 10, 2 );

Hello David,
i`m sorry but it doesn´t works. Maybe it is better to cancel this author box?

[David]

Hmmm… did you se the array: $author_list = array( 'display name', 'another name', 'another name' ); to include the author display names ?

[Nadine]

Yes I have seen. And i filled it with my author-names

[David]

And the ID of the element? ie.

The 137 in this line needs changing to match the Elements ID?

if ( 137 === $element_id

Sorry for the back and forth, but i tested the code on my local site and it works.

[Nadine]

Yes of course. I have changed id-number like 156224 (https://www.kagels-trading.de/wp-admin/post.php?post=156224&action=edit)

[David]

Can you Edit the Element and remove ALL the Display Rules. There should be none as the code is what sets them.

Hello David, yes I have deleted all display rules, but the box will not show in my blog posts.
