Loosing my mind. Dynamic Select Choices inside repeater.

I have a repeater that contains a select field.

Im using the load_field filter to dynamically populate the select fields’ choices on a custom post type.

The data comes from a custom database table and are simple date values.

The database gives me an array in the following format.

$dates = [
'2020-12-30'=> '30.12.2020',
'2020-12-31'=> '31.12.2020',
]

So far so good.

Here comes the issue that is making me lose my mind.

$field['choices'] = $dates;
				
return $field;

Does result in the select field having no choices at all.

However, returning the same array $dates hardcoded to the filter works perfectly as expected.

$dates_manually = [
					
'2020-12-30'=> '30.12.2020',
'2020-12-31'=> '31.12.2020',
]; 

$field['choices'] = $dates_manually;
				
return $field;

I tried it all. var_dump, array_diff. Everything. Its the same array. However the dynamically create $dates array results in an empty select field while the manually created one works.

I hope anybody has an idea.

I put the code I use in a GitHub Repo if that helps anybody.

Thank you very much.

What makes this even more confusing is that the exact same code works perfectly fine for a normal select field that is not inside a repeater.

I have looked at your code and I don’t see any reason that this should be happening.

Try using an acf/prepare_field filter instead of a acf/load_field and see if this makes any difference.
