Using the shortcode i get a warning (but no output):
Warning: foreach() argument must be of type array|object, null given inC:\Users\Dee Ego\Local Sites\bricksbuilder\app\public\wp-content\themes\bricks-c\functions.phpon line172
I tries also with a code block (it’s an element like the Shortcode on bricks editor)
<?php echo do_shortcode( '[display_book_chapters id="'.$post_id.'"]' ); ?>
and in this case i get 2 warnings:
Warning: Undefined variable $post_id inC:\Users\Dee Ego\Local Sites\bricksbuilder\app\public\wp-content\themes\bricks\includes\elements\code.php(160) : eval()’d codeon line2
Warning: foreach() argument must be of type array|object, null given inC:\Users\Dee Ego\Local Sites\bricksbuilder\app\public\wp-content\themes\bricks-c\functions.phpon line172
In any case, these solutions would not be ideal, as they do not take advantage of bricks’ internal query system, that is, in making the Repeater appear as a post type in the indicated dropdown.
You can update the function to check if the chapters are available.
function display_book_chapters( $id ){
$chapters = pods_field( 'book', $id, 'chapter' );
if( ! empty( $chapters ) ){
foreach( $chapters as $i => $chapter ){
echo '<div>';
echo $chapter['name'];
$pdf_url = wp_get_attachment_url( $chapter['pdf'] );
if( $pdf_url ){
echo '<a href="' . $pdf_url . '">PDF</a>';
}
echo '</div>' ;
}
}
}
I think the problem is that {post_id} doesn’t pass in the correct post id into the shortcode. You can test it by echoing {post_id} without the shortcode, and contact Bricks if necessary.
I don’t think $post_id can be used before declaring it. You could try {post_id}.
the Repeater is not a post type. It is a field of a Pod which can be a post type.
Updated functions: warning disappears, but no output.
in my case echoing {post_id} results in 336, which is the right one.
I also test php code above and also shortcode with hardcoded 336: no warning in this case, but neither the repeated Name/PDF.
I know that is not a post type, but the repeater (if present in page) should appears in dropwown: check the ACF version at 14:05 https://www.youtube.com/watch?t=845&v=72zSZ6AOU6Y
Is 336 an ID of a book page?
I noticed a mistake. Please update the function this this:
function display_book_chapters( $args ){
if( isset( $args['id'] ) ){
$chapters = pods_field( 'book', $args['id'], 'chapter' );
if( ! empty( $chapters ) ){
foreach( $chapters as $i => $chapter ){
echo '<div>';
echo $chapter['name'];
$pdf_url = wp_get_attachment_url( $chapter['pdf'] );
if( $pdf_url ){
echo '<a href="' . $pdf_url . '">PDF</a>';
}
echo '</div>' ;
}
}
}
}
using shortcode
[display_book_chapters id={post_id}]
it works!
Do you think you can integrate this to the Bricks UI, like ACF on above video?
🙂 Brilliant.
I will look into it when I am less busy.
Nice! this can be a good starting point.

For additional question I think Bricks staff will be glad to help you.
