< p > For example, given the following form:< / p >

< input type="hidden" name="_method" value="DELETE">

< p > Browser-based submission of content types other than form are supported by using form fields named < code > _content< / code > and < code > _content_type< / code > :< / p >
< p > For example, given the following form:< / p >

< p > Nope. It was at one point intended to support < code > PUT< / code > and < code > DELETE< / code > forms, but was later < a href = "3" > dropped from the spec< / a > . There remains < a href = "4" > ongoing discussion< / a > about adding support for < code > PUT< / code > and < code > DELETE< / code > , as well as how to support content types other than form-encoded data.< / p >
