Meta Box

Hey Peter,

you got me wrong. The block has indeed user input, but the user needs to input something. To see what it is about, it would be nice to giving users a clue what the block inside the editor is about without having to take a look in sidebars (the mb blocks sidebar is almost useless since the only thing it shows are the mb blocks title and the advanced tab). An use case for this could be a page template. The MB Blocks initial state renders only, "Click the Edit icon in the block toolbar to enter content." Besides that I disagree: Rendering a block without user input is indeed meaningful, since in the current state 'std' values are confusing because they don't trigger a render inside the editor, like a real input would do.

You can take this as a feature request.

A minimal approach would be turning this initial state from https://imgur.com/pJo5UU2 into something like this https://imgur.com/BW0Ettw, but an initial preview is much appreciated to provide a nicer user experience.

It was happening with my own custom blocks, I tied them to my custom theme, so switching to Twenty TwentyTwo is pointless. No standard blocks involved. I did not find any errors in my own blocks and since it is not happing on a new page with the same block arrangement I am totally okay with not debugging it further. The first log error is Uncaught SyntaxError: Unexpected token '<' (at post.php?post=2&action=edit:125:1) which I don't know what to do with, followed by a bunch of "unable to register block type errors" for all my own blocks. And the mb-block related error I posted above.

Sure, if I remove the script tags, the error is gone. I switched to reading data-attributes instead of inlineing JS to avoid this altogether. However, there is no difference in using render_callback or render_template, it's still not possible to use a script tag.

My example callback is

function test_callback($attributes, $is_preview = false, $post_id = null)
{
    ?>
<script></script>
hello from render callback
<?php
}

The Meta Box version is 5.6.4

I would suggest adding this property to the docs.

I have a feature request then: Please support external template files like in mb views

Obvious 🙄, thank you!
