Hello,
We were having an issue with the new meta box group clone functionality in that we couldn't add additional items when editing a page. One of my developers provided me with the following notes and code update that was made to fix the issue. We're not sure if this is a permanent fix but hopefully it lets you know where the issue is. Let me know. Thanks.
----------------------------------------------
[…] here is what I have done to fix the metabox group functionality issue: to populate a metabox group in a page you have to click on "+ add more" button so that it creates a new item to be populated.
This new item is inside a form to be submitted, the indexes created for these new item names should increase but there is a bug in JS in wp-content\plugins\meta-box\js\clone.js about line 21.
I changed this:
if ( name && !$field.closest( '.rwmb-group-clone' ).length ){ $field.attr( 'name', cloneIndex.replace( index, name, '[', ']', false ) ); }
to this:
if ( name){ $field.attr( 'name', cloneIndex.replace( index, name, '[', ']', false ) ); }
Content item always have a ( '.rwmb-group-clone' ) close so I removed that from the condition. Now the condition is true and the index is incremented, it works now, not 100% sure if that could be a definitive fix but at least plugin author can see what the problem is.
