[PHP] Associative array key as a variable

[ejfs]

Hi.

I have the following PHP program executed from an HTML form where I pass
the associative array key name as a variable:

?
function show($name)
{
  $cnt = count($HTTP_POST_VARS[$name]);
  echo Count for $name is $cnt;
  echo br /;
}
show(countries);
show(cities);
?

The result is always 0. The form fields do have name=countries[] and
name=cities[] to indicate an array.
When I hardcode the count line in the function as follows just to test
to make sure the transfer from the browser works, it displays a correct
non-zero result:

  $cnt = count($HTTP_POST_VARS[cities]);

I even tried these statements in the function but all give a 0 result:

  $cnt = count($HTTP_POST_VARS[.$name.]);

How do I get the count line to work with a variable in the function?
Thanks,

Eurico

[PHP] HTTP_POST_VARS problem

[ejfs]

Hi. I'm a newbie at this and am having problems understanding how this
works.

I have a form with method=post. The server program does display
REQUEST_STRING as I expect (e.g., choice=yes but displaying
HTTP_POST_VARS[choice] is null). However, displaying
HTTP_GET_VARS[choice] does display yes. Running phpinfo() displays
that the REQUEST_METHOD = GET. Why is this GET and how do I get it set
to POST? How do I get HTTP_POST_VARS to work since my form does have
method=post?

Here are some php.ini settings (I'm running PHP 4.1.1 with Apache 1.3.22

under Win98):

variables_order = EGPCS
register_globals = On
register_argc_argv = On
gpc_order = GPC

Thanks...

Re: [PHP] HTTP_POST_VARS problem

Please ignore my question - I just figured it out. I had the method=post
in the input type=submit tag rather than in the form tag. It works!

However, if one has an HTML select/option menu scrolling list with multiple
selections, how does one get the number of values for the same name with
HTTP_POST_VARS? Or how does one scroll through the list of choices passed?
Thanks,
