Try to develop a Block Count block using ACF-Pro and no JavaScript

[bobbingwide]

Closing this now. I tried and succeeded.

With ACF PRO v6.1.6 the HTML for the acf/block-count block is simpler

<!-- wp:acf/block-count {"name":"acf/block-count","data":{},"mode":"preview"} /-->

• data is now an empty array
• align defaults to null so the attribute isn't set

When the value is changed in the seamless metabox, the block count doesn't update automatically.
You need to choose Update then view the post.
Different versions of Preview don't pick up the change, since it's not yet been applied in the server.

When I changed the Field Groups Settings so that the block count could be edited within the block

then the value entered ( 33 ) didn't override the value stored in meta data ( 42 ).

<!-- wp:acf/block-count {"name":"acf/block-count","data":{"field_5dc8302fb9fa3":"33"},"mode":"edit"} /-->

I'll need to read the docs. The original code just accesses the post meta data using get_field()

function acf_oik_blocks_callback( $block, $content, $is_preview, $post_id  ) {
	bw_trace2();
	echo "Block count: ";
	$block_count = get_field( '_block_count', $post_id );
	echo $block_count;
}

Since ACF PRO 6.0 block.json became the recommended way of registering blocks - matching the native WordPress registration methods.

See https://www.advancedcustomfields.com/resources/blocks/

We should update the code to register this block using this method.

Additional blocks to register are:

block name	rendering method	function / file
acf/block-count-2	renderCallback	acf_oik_blocks_callback
acf-oik-blocks/block-count-3	renderTemplate	block-count-3.php
