acf_register_block_type via array loop

    Hi,

    I’m trying to automate the block build process so we only have to make a file in the /block/ directory. It loops the files, gets the variables from the first comment en puts it in the acf_register_block_type(). However it gives an error (translated from dutch): WP_Block_Type_Registry::register is’nt called correctly. Bloktypenames must contain a namespace before the name . E.g.my-plugin/my-custom-block.

    My code:

    functions.php

    <?php 
    /**
    * GUTENBERG INITIALISATION
    */
    add_action('acf/init', 'my_guten_acf_init');
    function my_guten_acf_init() {
    
      // check function exists
      if( function_exists('acf_register_block') ) {
    
        // register a testimonial block
        $blockdir = get_theme_file_path('/template-parts/block/');
        if(is_dir($blockdir)) {
          $dir = new DirectoryIterator($blockdir);
          foreach ($dir as $fileinfo) {
    
            if (!$fileinfo->isDot()) {
                $filedoc = getFileDocBlock($fileinfo->getPathname());
    
                $pattern = "#(@[a-zA-Z]+\s*[a-zA-Z0-9, ()_].*)#";
                $arr=array('name'=>'test');
                preg_match_all($pattern, $filedoc, $matches, PREG_PATTERN_ORDER);
                foreach($matches[0] as $value) {
                  $output=array();
                  $value = substr($value,1);
                  parse_str($value, $output);
    
                  $arr[key($output)] = $output[key($output)];
                }
    
              acf_register_block_type(array(
              'name' => ''.strval($arr['name']).'',
              'title' => $arr['title'],
              'description' => $arr['description'],
              'render_callback' => 'my_guten_acf_block_render_callback',
              //'render_template' => 'template-parts/blocks/testimonial/testimonial.php',
              'category' => 'my-blokken',
              'icon' => 'admin-comments',
              'keywords' => explode(',',$arr['tags']),
              'supports' => array(
              'align' => false,
              )
              ));
            }
          }
        }
      }
    }
    
    function my_guten_acf_block_render_callback( $block ) {
      // convert name ("acf/testimonial") into path friendly slug ("testimonial")
      $slug = str_replace('acf/', '', $block['name']);
    
      // include a template part from within the "template-parts/block" folder
      if( file_exists( get_theme_file_path("/template-parts/block/content-{$slug}.php") ) ) {
        include( get_theme_file_path("/template-parts/block/content-{$slug}.php") );
      }
    }
    
    function my_guten_plugin_block_categories( $categories, $post ) {
      //to show other blocks, uncomment $categories
      return array_merge(
        //$categories,
        array(
          array(
            'slug' => 'my-blokken',
            'title' => __( 'My custom blokken', 'my-plugin' ),
            'icon' => 'wordpress',
          ),
        )
      );
    }
    add_filter( 'block_categories', 'my_guten_plugin_block_categories', 10, 2 );
    
    function getFileDocBlock($file){
      $docComments = array_filter(
        token_get_all( file_get_contents( $file ) ), function($entry) {
          return $entry[0] == T_DOC_COMMENT;
        }
      );
      $fileDocComment = array_shift( $docComments );
      return $fileDocComment[1];
    }

    in /block/content-{name}.php i have the following comment:

    
    <?php
    /**
    * Block Name: Header voorpagina
    * @name=headervoorpagina
    * @title=Header voorpagina
    * @tags=header,voorpagina
    * @description=de beschrijving
    */ ?>
    

    Is it even possible to get the blocks registered trough a loop?

  • We would be interested in this concept too.
