Howto write an image upload CGI script?

ruby-talk
1

Hello everyone,

being new to ruby and CGI scripting I’m having some trouble writing an
upload script. Maybe someone can give me a few pointers.

I have a working .rbx that goes like this:

cgi = CGI.new
file = cgi[‘file’]
cp -v #{file[0].local_path.untaint} \ /targetdirectory/#{file[0].original_filename.untaint }

Problems:

  1. I don’t like using `` without a good reason,
    how do I do this the ruby way ?

  2. What I’d really like is a script that would be able to upload
    several files at once.
    I’ve heard this is not an easy task; suggestions ?

  3. Is there a way to have apache write the file straight to the target
    directory so I don’t have to make a copy at all ?

Thank you for your time,
Simon

PS: If you are concerned about security problems in my script: it is only
meant to be used by me inside my private network.

Hello everyone,
Hi

  1. I don’t like using `` without a good reason,
    how do I do this the ruby way ?

maybe you’re looking for
system(“command here”)
?

or do you want avoid using system’s cp?
in that case you could use ftools to move, copy and so on.
(I discovered ftools.rb imn this list little time ago, and I loved it
:slight_smile:

  1. What I’d really like is a script that would be able to upload
    several files at once.
    I’ve heard this is not an easy task; suggestions ?

I think you can easily get via several values, and iterate
through them, or am I missing the point?

I presume you are using a form something lke this:

<form enctype="multipart/form-data" action="foo.rbx" method="post">
<input name="file" type="file">
<br><input type="submit">
</form>

You should be able to have multiple uploads just by having multiple input
fields with name="file1", name="file2" etc (all with type="file"). Have you
tried it?

I have a _working .rbx_ that goes like this:

cgi = CGI.new
file = cgi['file']
`cp -v #{file[0].local_path.untaint} \
  /targetdirectory/#{file[0].original_filename.untaint }`
