Gutenberg post preview doesn't display ACF custom fields

[sebrosen]

When I add a custom field to a post and try to preview it, the custom field is not displaying. This only happens if the post have been published. If the post is just a draft, then the preview work as expected.

This only seems to be an issue if you use the ACF functions get_field or the_field. I tried displaying the custom field using get_post_meta and then the preview worked as expected.

I saw other people have reported the issue and that there's not currently any solution, but I wasn't sure if you were aware that it does indeed work fine if you use get_post_meta

Hi @sebrosen

Thanks for the info. How strange!?
I'm glad to hear that it is possible to preview the meta, so perhaps the issue is with loading the ACF field settings.

I'll perform some investigation shortly and will be in touch with my findings.

[sebrosen]

Thank you for looking into it!

Hey, sorry, I'm curious if you were able to look into this?

Hi @sebrosen

Not yet, but this is near the top of my to-do list :)

[sebrosen]

Fantastic! Keep up the good work :-)

Hi, i have the same problem. I've found a workaround using this code snippet: WordPress/gutenberg#12617 (comment)

A current active thread, but without solutions: WordPress/gutenberg#16006

I'm using Sage Roots theme, latest Wordpress.

Has this ever been addressed, @elliotcondon ? Knowing sometimes multiple Issues could have been made for the same thing, I didn't know if there were other discussions on this elsewhere that I missed.

I'm running ACF Pro 5.9.5 on WP 5.7 and this still seems to be an issue for me, unfortunately. Client wants to add a new image to their slider (via ACF Repeater) but when previewing the page the code fails the has_rows() check. A get_field() call returns NULL also.

Hey Elliot, just wondering if a fix might be close for this one? We've noticing it on a new site with latest ACF and WordPress.

Just wanted to add. I have been experiencing this issue with WP 5.7.2 and ACF PRO 5.9.6 (Have also tried 5.9.3) with all other plugins disabled.

Updating fields in the block editor works great. The changes can be seen in the preview, however if the fields are on the post itself, it doesn't work and you need to update the live post or switch to draft and save as a draft to preview.

Hope that can help debugging this issue. As always, massive thankyou for all your hard work.

Edit: This is somewhat broken, YMMV

I am also encountering this issue with ACF blocks. The workaround from https://support.advancedcustomfields.com/forums/topic/custom-fields-on-post-preview/ seems to work.

I am also encountering this issue. For clarity: The workaround that @stefanfisk mentioned only ensures that the previously saved values show in the preview, however any edits to the page are not shown on the preview even with the workaround.

We also spotted this issue, it happens especially for repeater fields. Thanks for the workaround, but need fixing. +1
