Repeating fields

I’m not familiar with that plugin. Is this something you are using to set custom fields in the post? In which case the hidden field’s name should start with “meta_”. I think it should handle setting multiple values in the same field.

If I’m not understanding, please provide more context about ACF Repeater Fields.

I looked into this a bit further and it’s a bit more complicated than I originally thought. ACF has its own method of creating posts, and with Repeater Fields I found no other solution than to use ACF’s method.

$field_key = 'field_123123123123'; // corresponds with a meta_ field
$subfield_key = 'field_456456456456'; // repeating sub-field of $field_key
$post_id = $the_post_id; // gets the current post ID
$items = array('foo','bar','meh','cat','dog');
foreach ($items as $items_value) {
	$value[] = array($subfield_key => $items_value);
	update_field( $field_key, $value, $post_id );
}

The issue is that you when you use Repeater Fields, you can’t get a meta_ field by its name. You have to get it by its field key, which is generated by ACF when you create a custom field. Repeater sub-fields also have their own field keys.

Also, I couldn’t get this to work with update_post_meta, which FtP uses. I had to use update_field (which is native to ACF).

Sorry, I thought this would be an open-and-shut issue. I’ve posted a similar question on ACF’s forums – if they indicate a solution that allows FtP integration, I’ll share it here.

Thanks for writing back. Note that there are a couple of hook in F2P, form_to_post_before_create_post and form_to_post_set_values. Perhaps you can add code to those and call ACF functions to do what you want.
