Re: posting an array

i am posting a hidden values called accounts which is a number of usernames

print "<input type=hidden name=accounts value=\"@accounts\">";

the page that receives the data should be able to unpack the array but i am
having problems

&ReadParse();

foreach $line(@in) {
print "$line <br>\n";
}

shows accounts=username+username_001+username_002+username_003
as expected

but

$cnt=0;
@accounts = $in{'accounts'};
foreach $line(@accounts) {
print "$line<br>\n";
$cnt++;
}
print $cnt;

username username_001 username_002 username_003
1

all on 1 line, not 1 line for each value in the array.

what have i missed

You seem to have missed a few things. First, what you post via a form control is a string, not a list.

An array, such as

    my @accounts = qw/name1 name2 name3/;

returns a string with the elements separated with spaces and concatenated, if you surround it with double quotes.

If the usernames don't contain space characters, you can try

    @accounts = split ' ', $in{'accounts'};

Another thing is that your Perl coding style seems to be outdated. Please make it a habit to my() declare the variables and enable strictures and warnings. Also, it may be a good idea to start using the standard module CGI.pm instead of cgi-lib.pl (or whatever code you are referring to with "&ReadParse();").
