If is ACF block template

Question

I'm using ACF to build blocks.

Here's a simple function I've written via functions.php:

<?php
function my_test_function() {
    if ( is_page_template( 'template-parts/blocks/hero/hero.php' ) ) {
        echo '<p>I appear via the hero.php template.</p>';
    }
    if ( is_page_template( 'template-parts/blocks/video/video.php' ) ) {
        echo '<p>I appear via the video.php template.</p>';
    }
}
?>

Here's how I call the function via hero.php and video.php

<?php
    my_test_function();
?>

When I test this, nothing appears. I'm guessing the is_page_template function doesn't work in this instance as it's technically not a page template.

Is there another function that might work with ACF block templates?

You could use parse_block() : https://developer.wordpress.org/reference/functions/parse_blocks/ then loop through blocks to check if blockName exist for this page :

function check_if_block_exist($block_handle) {
  $post = get_post(); 

  if(has_blocks($post->post_content)) {
    $blocks = parse_blocks($post->post_content);

    foreach( $blocks as $block ) {
      if($block['blockName'] === $block_handle) {
        return true;
      }
    }
    return false;
  }
}
