When I use a repeater in a Block, the preview isn’t loading the data properly. For example: I have a Carousel block with a Text field and a Repeater field. The Repeater field contains an image field. When I add my new Carousel block to my page, I can edit just fine, I add a title and 2 photos within the Repeater field.
Then in the callback php I have the following:
$title = get_field('title');
$carousel = get_field('carousel');
echo $title;
echo '<pre>'.print_r($carousel,1).'</pre>';
When I switch to Preview mode in the block it outputs the following:
Testing
Array
(
[5c12f0d68cc12] => Array
(
[field_5c12ecd7a3615] => 32
)
[5c12f1a48cc13] => Array
(
[field_5c12ecd7a3615] => 33
)
)
As you can see, the Title field outputs properly, but the Repeater array is not using keys I can use to access the photos and it is only returning the ID of the photo in the array instead of the Photo array that it is set to return.
This actually only seems to affect image fields, as adding a text field in the Repeater after the photo shows the correct key for the text field when I print_r the Array.
I know this was asked about 3 years from the time of my comment but still I am going to post it.
Today I was doing something similar and I faced the same challenge, on the template to render I was using have_rows() function, I switched to get_field() and a traditional php foreach and the preview worked as expected.
