Hello.
(How) can I query multiple data from form?
Foor form ala
<form>
<input name="foo"/>
<input name="foo"/>
/form>
I can use 'looks "foo"' to get array of values. Ok.
But Is there any way to extract values from such form:
<form>
<input name="key" val="key1"/><input name="tag" val="tag11/><input name="tag" val="tag12/>...
<input name="key" val="key2"/><input name="tag" val="tag21/><input name="tag" val="tag22/>...
/form>
to get something like [("key1", ["tag11", "tag12"]), ("key2", ["tag21", "tag22"]) ] ?
One of requirement is possibility to add additionally key and tags for this key (via button, using javascript).
Can I groupe such pairs using html?
Maybe I have to do like this:
<form>
<input name="key" val="key1"/><input name="tag-key1" val="tag11/><input name="tag-key1" val="tag12/>
<input name="key" val="key2"/><input name="tag-key2" val="tag21/><input name="tag-key2" val="tag22/>
/form>,
but i dont see any (simple) way to add dinamicly add other list of keyed tags in such manner (by user, o client side).
