Description (last modified by SergeyBiryukov)

When we call wp_prepare_attachment_for_js() too early, we see the fatal:

Call to undefined function get_media_states()

Introduced in [49223] from #42063.

To test in twentytwenty:

--- a/themes/twentytwenty/header.php
+++ b/themes/twentytwenty/header.php
@@ -26,6 +26,7 @@

        <body <?php body_class(); ?>>

+               <?php var_dump( wp_prepare_attachment_for_js( '28' ) ); ?>
                <?php
                wp_body_open();
                ?>

You will see it fatal.

Just for reference, what's the use case for calling this in such a context (JS front end, something else)? This will help make sure we make the right fix and don't break it again in the future.

@helen Correct, specifically, we've seen usages for it in shortcodes, template tags, etc.

Since I see that we check for the existence of get_compat_media_markup above, I think we can do the same behavior here?

Yeah I think it makes sense to just do it the same as get_compat_media_markup given the context. More broadly I kind of feel like it should actually be filtered in closer to usage time since it's just a string and not super useful without more futzing outside of the specific admin usage but that's probably too much to be messing with for not a ton of benefit.

Just tested this and it's working after patch with the example code given to fatal.

I can reproduce and the fix works as expected, thanks for catching it @rebasaurus

In 49613:

Media: Avoid fatal error in `wp_prepare_attachment_for_js().

In certain contexts, in particular on the front-end, get_media_states() is not availble.

Props rebasaurus.
Fixes #51791.
