when cgi script read data, posted from html form with "post" post method, the read sub return zero of readed bytes, but $ENV{'CONTENT_LENGTH'} hold (for example) 7 bytes.

Any idea? Where I'm wrong ?

Here is my html from and cgi script:

===========================
some_file.html
---------------------------















==============================





================================
script.pl:
--------------------------------
#!/usr/bin/perl

use CGI qw/:standard/;
print header;

$length = $ENV{'CONTENT_LENGTH'};
$count = read (STDIN, $buffer, $length);
print "readed actually: $count, length: $length";
================================

Yes, I may solve this problem when getting form input touch CGI.pm, but the code above is correct, isn't it?

Edit by [tye], remove PRE tags, other formatting clean-up

Once you've issued "use CGI", then the CGI module is managing your GET/POST data for you, including slurping up STDIN as needed. Look at the param method/routine in the CGI docs to get at your data.
