Beta 4.2: Return the array from the gallery field

Beta
#1

I have tried to return the array of ID’s from the ACF’s Gallery field. I assume this should now be possible, but I have failed to find a way. :slight_smile:

Tomorrow I will play with maps, to see if and how could the new goodes be utilized with creating maps that contain dynamic pins based on ACF data.

Would love to know how you get on with the maps @Misho esp if it can be via the long/lat

@Misho I didn’t try the gallery! I’ll poke around at it, but here’s a thought off the top of my head.

When the Dynamic Content looper initializes, it expects an array and doesn’t really care what is inside.

  • If the item returned is not an array, it will wrap it in an array making it an array with a single value.
  • If the array contains WP_Post, WP_User, or WP_Term objects, it will make those available as the dynamic content context
  • If the array contains scalar values (strings, numbers, etc.) that value will be accessible through the Looper: Current Item dynamic content.

That might be how you can utilize the ID, although it will be tricky to pass that to an image without the dev console until I fix this issue: Adding DC to an image - featured image is gone

Thanks @alexander! I actually wasn’t clear enough. I wanted to dynamically populate a simple WP gallery shortcode, that accepts comma-seaparated IDs.

Oh gotcha! I was able to make some adjustments to allow this:

{{dc:acf:post_field field="gallery"}}

to simply output: 1234,4321,5678 when connected to a Gallery field. Just make sure Image ID is set as the return type of the field. Before making that combined strings it will make sure the incoming values are strings/numbers first so it will output nothing if the types are set to Image array or image object.

Give that a try in the next beta (hopefully tomorrow).

Hi @alexander!

The dynamic output works perfectly on its own: {{dc:acf:post_field field="gallery"}}

However, when part of the Gallery shortcode, it seems it isn’t working?

[gallery ids="{{dc:acf:post_field field="gallery"}}"]

Thanks!

I’ve checked on this, and you’re right, it’s not working in most elements. There are some discrepancies to the order that do_shortcode and Dynamic Content get processed depending on the context. I’ve fixed this for Text, Content Area, and Raw Content, but making sure it works everywhere will take a more involved audit.

Those cover over 90% of uses. I’m happy. :slight_smile:
