Upload in Form
Embed the uploader inside an HTML form alongside other fields. Upload files as part of a larger form submission.
What you should see: the uploader inside a normal form. Files transfer out of band and their identifiers are submitted with the rest of the fields on post.
<form method="post">
<div>
<label for="title">Title</label>
<input type="text" id="title" name="title" />
</div>
<div>
<label>Attachments</label>
<core-upload asp-upload-url="/api/upload/upload"
asp-multiple="true"
asp-progress="true">
</core-upload>
</div>
<button type="submit">Submit Form</button>
</form>
