Posting name="abc def"

[Jochen Daum]

Hi !

If I have an input field

<form ... method="post">

<input type="text" name="abc def">

</form>

It always comes through as

$_POST["abc_def"]

I tried urlencode and rawurlencode and can't quite understand why it
is changed somwhere.

Converting " " to "_" is not quite what I want, because it should be
working with generated field names.

Any ideas?

Jochen

Yes. Use valid HTML.

Read the HTML 4.01 spec, specifically section 6.2:
(http://www.w3.org/TR/1999/REC-html40...tml#type-cdata)

To make it painfully obvious:
"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 ("."). "

A space is not valid inside of a name. Therefore, you should be happy that
PHP accepts it at all. (It may actually be the browser that's changing it
too, I'm not sure... the behaviour is undefined since it's not valid HTML.)

Ok, I solved it by using

name="name[keyfield1;keyfi eld2]"

which at least works with spaces. Not a good idea I know.

However, . is turned into underscore by PHP, though its valid HTML
obviously. Just wondered, why this is.

The above is valid HTML.

The name attribute of the INPUT element is defined in the HTML DTD to
be of type CDATA, not of the restricted types ID or NAME.

There are no further restrictions on the values of the INPUT name
attribute listed in the specification.

See:

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&th=d1d0900133801803&seekm=Xns93D0F280540D0dkwwashere%40216.168.3.30&frame=off

... starting with David K. Wall's post that made the same assertion,
and read mine and Tad McLellan's replies.

PHP applies its own restrictions on accepted values of the name
attribute, presumably inherited from the register_global s=on days;
names are restricted to those that are valid for PHP variable names,
and are rewritten using underscores for invalid characters.

Hmm, nevermind, it seems as if I am incorrect. Read Andy's post for more
information.

Sorry.

Hmm... interesting. Good to know. Personally though, I'll stick with names
valid in C :-)

Sorry to the original poster for my incorrect reply.

Well, the . is the concatenation operator in PHP, so they need to be
changed to something that is valid in a PHP variable name.
