Empty repeater is not empty if containing a file field #721
Description
Expected Behavior:
The meta value of the repeater group to be empty
Actual Behavior:
Instead returning one entry in the array with a file_id field containing 0
get_post_meta(...) array(1)
→array(1)
'myprefix_file_id' => integer 0
Steps to reproduce (I have confirmed I can reproduce this issue on the trunk branch):
- Save a post without filling these data in
- Output the data of the meta - try to compare with version 2.2.1
CMB2 Field Registration Code:
add_filter( 'cmb2_meta_boxes', function( $meta_boxes ) {
