edit via function php the gallery in posts created with gutenberg

问题

I'm trying to modify the html output of the gallery that is provided by gutemberg via function php ... but I can't.

How do you intercept and modify yourself?

this is the original:

<ul="wp-block-gallery columns-2 is-cropped">
  <li class="blocks-gallery-item">....</li>
  <li class="blocks-gallery-item">....</li>
</ul>

and I would like to change it based on the number of columns to adapt it to my development framework ...

<div class="grid-x">
   <div class="box-50">...</div>
   <div class="box-50">...</div>
</div>

exists how to change it via function.php ??

Solution:

Exemple of Wp gutenberg html output override via function php:

add_filter( 'render_block', 'GutenGallery' , 10, 2 );

  function GutenGallery( $block_content, $block )
  {

    if ( 'core/gallery' !== $block['blockName'] || ! isset( $block['attrs']['ids'] ) )
    {
      return $block_content;
    }

    $li = '';
    $col = $block['attrs']['columns'];

    foreach( (array) $block['attrs']['ids'] as $id ) {

      if( $col == "1" || !$col)
      {
        $li .= sprintf( '<div class="box-[50-50-100]"><div class="autocrop radius-medium" style="height:300px;">%s</div></div>', wp_get_attachment_image( $id, 'large' ) );
      }
      elseif ($col == "2" )
      {
        $li .= sprintf( '<div class="box-[50-50-100]"><div class="autocrop radius-medium" style="height:300px;">%s</div></div>', wp_get_attachment_image( $id, 'large' ) );
      }
      elseif ($col == "3" )
      {
        $li .= sprintf( '<div class="box-[33-33-100]"><div class="autocrop radius-medium" style="height:300px;">%s</div></div>', wp_get_attachment_image( $id, 'large' ) );
      }
      elseif ($col >= "4" )
      {
        $li .= sprintf( '<div class="box-[25-25-50]"><div class="autocrop radius-medium" style="height:300px;">%s</div></div>', wp_get_attachment_image( $id, 'large' ) );
      }

    }
    return sprintf( '<div class="grid-x gap-20">%s</div>', $li );

  }
