Artur Paikin 6f80ea709c Extract metadata from form, closes #153 ... This PR adds support for extracting metadata from `<form>` elements. This was asked #153 and came up elsewhere too, I believe. You can use it like this: ```html <form class="MyForm" action="/"> <input type="file" /> <input type="hidden" name="bla" value="12333"> <input type="text" name="yo" value="1"> <button type="submit">Upload</button> </form> ``` ```js uppy.use(DragDrop, { target: '.MyForm', locale: { strings: {chooseFile: 'Выберите файл'} }, setMetaFromTargetForm: true }) ``` Then UI acquire type plugins, like Dashboard, FileInput and DragDrop, before mounting themselves or doing anything else, extract FormData from the `target` `<form>` element (it must be a form currently), and merge the object with the global `state.meta`. This is done via `setMeta` method on core. Then, when a file is added, `state.meta` is merged to that file’s meta right away. The ability to add more fields via UI plugin MetaData is also still there, though probably needs an update. In addition a new `meta` option is added in core: ```js const uppy = Uppy({ debug: true, autoProceed: true, meta: { username: 'Artur' } }) ``` This way some data can be set right away, it becomes the initial `state.meta` object.		2017-06-28 20:21:23 -04:00
