PHP allows control arrays in forms e.g. this is a counter editing script
echo "<input name=\"counterd elname[]\" type=\"hidden\" value=\"";
echo "<input name=\"countern ame[]\" type=\"hidden\"
value=\"".$name str."\">";
echo "<input name=\"newvalue[]\" size=".VALUEWID TH."
value=\"".$valu estr."\">";
echo "<input name=\"delcount er[".$namestr. "]\" type=\"checkbox \">";
The resultant web page might look something like this, in part:
<td><font face="arial,hel vetica" size=2><input
name="delcounte r[www.mysite.co.n z:]" type="checkbox" ></font></td>
<tr><td><font face="arial,hel vetica" size=2><input name="counterna me[]"
type="hidden"
value="www.mysi te.co.nz:/20040313/index.shtml"> www.mysite.co.nz:/20040313
/index.shtml</font></td>
Control arrays in PHP offer significant advantages in processing form
input where there are a variable number of sets of the same elements
repeated multiple times down the page to allow a set of records of the
same data fields to be edited. The form elements are received back in the
processing script as an array which can be dealt with in a
straightforward for loop.
According to HTML 4.0 standards, the name of an Input element should
follow these conventions:
"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 (".")."
I don't see anything there about the square brackets which are part of
the PHP array syntax, but they seem to be accepted and PHP seems to be
able to turn all the elements it receives into an array on the submission
of the form to the processing script. Is there something in the CGI
conventions or HTML that it does permit this syntax? 21  6458

The name attribute of form controls doesn't actually accept a NAME token as
its value, it accepts CDATA. For an example of an attribute that takes a
NAME token, see 'http-equiv' http://www.w3.org/TR/html4/index/attributes.html

You've misread the HTML standards; please see some previous discussions: http://groups.google.co.uk/groups?hl...3801803&rnum=1 http://groups.google.co.uk/groups?hl...f3b43cf&rnum=2 http://groups.google.co.uk/groups?hl...3f07028&rnum=3
The name attribute of the <input> element is not of type NAME, it is of type
CDATA, and so [ and ] are valid characters within the value of that attribute.

This is a most unusual way to specify an address. Why have you put a colon
there?
Ordinarily, colons are used in that position to specify a different port to
use (instead of the standard port 80). e.g. http://www.example.com:8000/
Cross-posting to so many newsgroups isn't such a brilliant thing to do,

When asking for help in the newsgroups, it's generally a good idea not to
piss off the people who might just help you. Demonstrating that you're not
interested in behaving yourself, and then going further by telling people
that you're not interested in behaving yourself, doesn't do anything to
help you, either.
Cross-posting isn't appreciated, even worse if you don't specify a
followup-to (so all replies get directed to one place). It's the sort of
thing that gets you instantly ignored by the people who know the most about
the problems you're asking about, and getting told not to do it by a lot of
other people. Making silly excuses about it just makes you look even
stupider.
