Ticket #13306 (closed bug: fixed)

Opened 3 years ago

Last modified 3 years ago

File input added to serialized forms caused a change in behavior and only halfway follows spec

Component: ajax Version: 1.9.0

According to the  spec, file inputs with files attached should be serialized with special values. However, plugins that specialize in uploading files, such as jQuery File Upload, handle serializing file inputs for us and they do it in ways that are able to take advantage of some HTML5 features when available. In other words, I think all we need to do is what we did before 1.9, which was ignore file inputs in serialization.

This  test case demonstrates the difference in serialization between 1.8 and 1.9 and shows that the value is still empty string when files are attached.

Ref #12134 where the bug was introduced. Although the spec says type="file" should be serialized, jQuery itself doesn't serialize them so we should leave them out. It should just be a case of adding file to the rsubmitterTypes regex.

Correction, we don't leave the value empty, but it's still true that we don't serialize it to spec.

Ignore file inputs when serializing forms. File input serialization is handled by plugins. Fixes #13306.
