I am trying to tackle registering gutenberg blocks in a more object oriented way. My goal is to eventually only have to write something like this:
$my_block = new GutenbergBlock($args);
The problem I am running into is when I have to set the render_callback function. The function acf_register_block() wants a string of the function name to use as part of the arguments and I would like that function to be a method on the class or maybe set by a method on the class, maybe a method that returns the an anonymous function based on certain class properties. I want to dynamically give it something callable through a class function.
I currently don’t see any way of doing that since the render callback function requires the $block variable as well as a couple others and those pieces of context are not present in my class context. I feel like if there was some way to hook into the render_callback process and add to the context I could also pass in other properties from my class to use in the render_callback.
A practical example is when I want to use Timber and twig to render the block. I need to write something like this in my callback function:
Right now, I cannot get that $name_of_template_file to be dynamic because the render function is called in a completely different context than my class and I’d normally set that in my class. I’ve resorted to use a templating file structure that mirrors the name of the block to at least make it partially dynamic. This way I can write something like:
$new_block = new GutenbergBlock(array('name' => 'my-cool-block'));
Then in my callback function for that class I write:
This at least makes it partially dynamic, but not all the way. I would love to not have to stick to a folder structure and just pass in that template variable dynamically somehow. But since the render callback is called in a different context than my class I cannot. At least not yet. I could be missing something completely obvious to a more skilled PHP programmer.
That was a super long-winded post. I hope someone else knows a solution or at least sympathizes with my plight. Or at the very least even understands what I am saying.
