Need method to detect if meta data should be cloned or not?

[bobbingwide]

When the fields defined for a post type differ between sites then it's possible to clone content values which are not defined therefore could contain invalid data.

oik-clone provides a filter function to determine which meta data should be cloned. can this be used by oik-fields to check the definitions? see oik_clone_filter_all_post_meta()

problem 1 - invalid field values used

_documentation_home node ref field not defined on target site so no ability to detect and correct the value that's been cloned. this can lead to blank documentation.

problem 2 - data overwrite

fields which contain counters that are updated individually should not be overwritten on updates.

Proposed solution

The function referred to in see oik_clone_filter_all_post_meta() did not actually implement a filter function. The logic will be changed to invoke the filter oik_clone_filter_all_post_meta. This will be invoked multiple times.

• During oik_clone_delete_all_post_meta() - when deleting post meta from the target. Here the implementing filter function removes the fields that should not be deleted.
• During oik_clone_filter_all_post_meta(). The filter is invoked before applying relationship mapping. Again the filter function removes fields that should not be inserted.
