Re: Getting a filehandle for uploaded file

[bv]

Is the problem that you are trying to read from the filename, not the filehandle? From the CGI documentation:

To be safe, use the upload() function (new in version 2.47). When called with the name of an upload field, upload() returns a filehandle-like object, or undef if the parameter is not a valid filehandle.

Pulling a quote from Bloodnok's post below:

If there was a problem uploading the file -- for example, the file was bigger than the $CGI::POST_MAX setting -- $filename will be empty. We can test for this and report the problem to the user as follows:

So you could test for that, too.

I've tried using the upload function. It returns undef, which, according to the man page, means the parameter is not a valid filehandle. But why not? I have a normal looking form field:

<input type="file" name="file_image" ...

I've done the test according to your second quote. There's definitely nothing coming back from:

  my $handle_in = $cgi->upload('file_image');

But it's not a POST_MAX problem. That's set to -1, which means no limit. There's a function called cgi_error(), but that's not returning anything either.

Did you specify the correct enctype for your form?

<form enctype="multipart/form-data" method="POST" ...>
