Re: posting an array

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

&ReadParse();
what have i missed


One of the things to consider is that you should 'use CGI;' instead
of cgi-lib.pl.  It also appears that you are not aware of qq():

  print qq(<input type=hidden name=accounts value="@accounts">\n);

or

  print qq(<input type="hidden" name="accounts" value="$_">\n)
						for @accounts;


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. 

Of course.  print("@accounts") outputs a single string consisting
of the printable equivalent of all the items in the array
separated by blanks (or whatever $" is set to).

Either
  1) leave the form creation script as is and change the receiving
     script to convert the incoming string back into an array,
or
  2) leave the form receiving script as is and change the creation
     script to output multiple input tags with the same name.

Use
  print qq(<input type="hidden" name="accounts" value="$_">\n)
						for @accounts;
to create multiple lines of output like this:
<input type="hidden" name="accounts" value="$accounts[0]">
<input type="hidden" name="accounts" value="$accounts[1]">
<input type="hidden" name="accounts" value="$accounts[2]">
....
