Hi @jonhenshaw –?those top two block templates look good to me. However, block_field doesn’t work inside of single.php, or any theme template (even if you’re inside of the loop, as I presume you are in the example).

The main reason is because there’s no way for block_field to know which block you’re referring to. Even if there were a parameter for block_field to define the particular block template you’re trying to get (e.g. block_field( 'name', true, 'newsletter' )), it’s still possible you might have inserted multiple copies of that block in your post / page.

The only way of using block_field() or block_value() is inside the block template, which will be output when you use get_the_content() or the_content() in your single.php template.

I hope that all makes sense!

That’s good to know. It works for me and always has until I recently added the newsletter block after the ratings block. But based on what you’re saying, it shouldn’t be working. If you view the source of https://coywolf.reviews/software/memberful-review/ you’ll see that the Schema is fully populated by it. So I guess I’m utilizing a feature that was never intended to work but does under certain circumstances. I’ll probably keep using what appears to be a hack for the time being. But it looks like what I need to do is migrate the Schema directly into the block. Thanks for your help with this.

You’re welcome!
