$_POST and multiselectable <select> tag

Hi,

If I put in the code the tag that can be multiselectable (a listbox
where I can select more that one item), how can I know what are the selected
items?

example, try this in a .php file (note the multiple="multiple" attribute):

-----------------
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">






echo("Selected:" . $_POST["List"]);
?>

Item 1
Item 2
Item 3

Ok, I thank you to let me lost time searching for this *complex* solution
(ah, select+multiple, not select+array) that is

name="list[]"

and not

name="list"

Good, this works... also if the "[]" is not valid in html4 name attribute :)

http://www.w3.org/TR/html4/types.html#type-name

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed
by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"),
colons (":"), and periods (".").

nor utility.

I'm programming and living NGs since 10 years: if I asked something that's
because I didn't find clear/secure asnswers on the web.

Thanks again for reply to me the same way as you replyed to other people in
the NG this day.

It is valid.

The name attribute is not of type NAME, see the DTD (and previous
discussions).

I do not know your background, nor your experience level. However,
having seen this question numerous times in the past few months, I
wanted to provide an answer that would not only solve your problem but
also possible additional problems immediatly (you do have to wait for
a person to answer your question, but if a person searches and the
answer already exists, instant satifaction.

Yeah, I did feel a bit odd yesterday. I even went home early. I
apologize if I offended you or you felt that I didn't give you a solid
answer.

this page tell exactly what I read:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed
by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"),
colons (":"), and periods (".").

so... NO "[]"

If that were the case, it wouldn't work, would it? But it does. On
every server, with every version of PHP, with every browser...

It does because you're looking at the wrong stuff. As Andy said, the
name attribute is not of type NAME. Look at the DTD.

Argue all you want. ELINTPimp and Andy gave you the correct answer.

This section is about basic types in SGML. ID and NAME are _types_. The
name _attribute_ is usually of type CDATA, so '[]' are perfectly valid.
