init hook function causes comments to be closed.

Hi

I’ve written myself a small plugin which takes a custom post type and uses an init hook action to select them and register them as block pattern using register_block_pattern and register_block_pattern_category.

This all works really well, BUT, it seems to cause a problem when you try and submit a comment. Basically, I’m getting a “Sorry, comments are closed for this item.” from wp-comments-post.php.

If I comment out the init hook call, comments work again.

I’m not really sure how to approach debugging this one!

This is the hook being called:

function grab_patterns_for_registration() {
		
	$patterns = new WP_Query( 
		array( 
			'post_type' => 'patterns',
			'post_status' => 'publish' 
		) 
	);

	if ( $patterns->have_posts() ) {
		while ( $patterns->have_posts() ) {
			
			$patterns->the_post();	
			
			$pattern_name = 'patterns/' . get_post_field( 'post_name');
			$content = get_the_content();
			$title = get_the_title();
			$postID = get_the_ID();		
			$category = get_post_meta(get_the_ID(),'pattern_category', true);			
			
			/* if no category is set, give it a default */
			if (!$category) {
				$category = 'Custom Patterns';
			}

			/* Add the category */
			register_block_pattern_category(
				$category,
				array( 'label' => __( $category, 'addpatterns' ) )
			);
				
			/* Register the block category */
			register_block_pattern($pattern_name, [
				'title' => __($title, 'addpatterns'),
				'categories' => [$category],
				'content' => $content,
			]);
		}
	} 
	/* Restore original Post Data */
	wp_reset_postdata();
}
add_action('init', 'grab_patterns_for_registration');
