Apache::Request->param() failing on POSTs

geektron has asked for the wisdom of the Perl Monks concerning the following question:

(i did find this Calls to Apache::Request's param method sometimes end the program and return no data that has a similar issue, but i don't have any closures ... just some straightforward (or so i think) access to an Apache::Request object.

the form submit mechanism is:

<form action="/admin/conference/build/pagetwo" method="get" enctype="m
+ultipart/form-data" name="form1">
[download]

if i change the GET to a POST, i get no values from the following:

my $req = Apache::Request->new( $pass->{r} );

warn "debug:" . $req->param('year') . "  " . $req->param('foundation')
+;
[download]

i read through the perldoc *again* for Apache::Request, and the only thing i could immediately think of as being *wrong* was the lack of a call to: $req->parse();, but i could be misunderstanding the following statement in the perldoc:

 parse

       The parse method does the actual work of parsing the request.  
+It is called for you by the accessor methods, so it is not required .
+....

am i incorrect in assuming that $req->param('foo') is and accessor method of $req?

What happens if you just pull the args() off of the Apache object? `my $formdata = $pass->{'r'}->content; warn $formdata->{'year'}." ".$formdata->{'foundation'};` [download] Don WHITEPAGES.COM \| INC Edit by castaway: Closed small tag in signature	[reply] [d/l]

i get: `Can't use an undefined value as a HASH reference at ...` [download] using: `warn "debug:" . $pass->{r}->content->{year} . " " . $pass->{r}->content->{foundation};` [download] which is the same, just no temp var. could i be missing something in my mod_perl install? that's all i can think of ...	[reply] [d/l] [select]

That could be important, Apache::Request uses that process for getting the POST content, which can only be read once. Maybe the content is already pulled somewhere. That would cause your original error and the undefined value error as well. How is $pass being defined? Don WHITEPAGES.COM \| INC Edit by castaway: Closed small tag in signature	[reply]

You might want to try the CGI module instead of Apache::Request. I don't understand why, but in researching my own similar mod_perl problems I came accross a mailing list posting saying that one worked while the other returned empty data: http://aspn.activestate.com/ASPN/Mail/Message/modperl/1013538 I'm curious, are you using mod_perl 1 or 2? I only recently started trying mod_perl 2 (never tried 1) and I also found a bug where it loses POST data. I asked about the bug on the mod_perl mailing list (http://gossamer-threads.com/lists/modperl/modperl/81790?#81790) but never got any response. -Joe	[reply]

i'm using mod_perl 1 and apache 1.3.x (don't remember the minor number). i know i could use CGI, but i've been trying to make more use of the Apache::* modules. but, reading the reference thread, something does stick out It seems to me like your processes are getting corrupted by some C code or an improperly shared file handle or socket. -- perrin the "improperly shared filehandle" sticks out the most. i have a feeling my precedessor's approach to the application may be part of the problem. (with a `local *TEMPLATE` stuck in one of the template loading modules) oh well, back to CGI	[reply] [d/l]

I know the difference for me has always been the size of the files in import and usage. While CGI works, I personally find my applications work faster if I do not use it with the mod_perl. I have stuck with 1.x simply for stability so far, but have also gone to parsing my data by hand for to speed up the process and reduce the memory size of the application.
