Hello everyone,
\nthe issue is reproducible when the user wants to remove the contents of a “file” field type and deletes the contents of the input element instead of clicking on the close button attached to the preview image.<\/p>\n

Expecting:<\/strong>
\nBoth meta keys (‘my_field’ and ‘my_field_id’) for the file field should be removed<\/p>\n

What happens:<\/strong>
\nOnly ‘my_field’ meta key is removed from the database while ‘my_field_id’ remains<\/p>\n

How to reproduce:<\/strong>
\n1. Create a new meta field of type file
\n2. Add an attachment
\n3. Save the post
\n4. Check database for ‘my_field’ and ‘my_field_id’ post meta
\n4. Delete the contents of the input field only
\n5. Save the post
\n6. Check database again, ‘my_field_id’ shall still be there<\/p>\n

Example code:<\/strong><\/p>\n

        $cmb = new_cmb2_box(\n            [\n                'id' => 'file_test_field',\n                'title' => "Test",\n                'object_types' => ['post'],\n            ]\n        );\n        $cmb->add_field(\n            [\n                'id' => 'my_field',\n                'name' => "Insert file here, then remove the input only and save the post",\n                'type' => 'file',\n            ]\n        );\n<\/code><\/pre>\n","protected":false},"template":"","class_list":["post-9452945","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/9452945","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/9452945\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=9452945"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
