Using p.ex. function from FAQ 7.1 to read HTTP_POST_VARS one
is unable to handle/see all key-value-pairs when key is the same for
multiple values. I did not find any way to see all pairs (well one might define an array as name but that is not what CGI standard expects I think).

p.ex. having something like this in a HTML form:

<input type=checkbox name="FORM_key" value="2">
<input type=checkbox name="FORM_key" value="8">
<input type=checkbox name="FORM_key" value="19">

would only result in:

FORM_key -> 19
sizeof($HTTP_POST_VRS) = 1

instead of

FORM_key -> 2
FORM_key -> 8
FORM_key -> 19
where sizeof would return 3.

This is most likely caused by using some kind of associative array instead
of using indexes. I did not manage to solve this by using other array f()s.
I do not have time to look at the source code - sorry.
A simple dirty quick hack perl-script shows you that one does get all the
three values:

--- snipp ---
#!/usr/bin/perl

printf("Content-Type: text/htmlnn");

if ($ENV{'CONTENT_LENGTH'} > 0) {
    read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});

     <email protected> = split(/&/, $buffer);

    printf("nPOST-Buffer (raw):<br>n");
    printf("%sn", $buffer);
    printf("nPOST-Buffer (split up):<br>n");

    foreach $pair ( <email protected>) {
            printf("%s<br>n", $pair);
    }
} else {
        printf("NO HTTP_POST_VARs -> nothing to do here<br>n");
}

# End;
