Re: Multiple form selections in cgi

The param method, when called with no arguments, returns a list of the names of all the CGI parameters.

foreach ($cgi->param()) {
   if (/^year_\d+$/) {
      push(@years, $cgi->param($_));
   }
}

which can be rewritten as follows:

@years = map { $cgi->param($_) }
         grep { /^year_\d+$/ }
         $cgi->param();

Thanks. This would definitely work, and fall within the definition of Or some variant that cycles through all form elements looking for anything named "year_x". For the sake of elegance, I'm wondering if there's not something else. Forget that fear of gravity, Get a little savagery in your life.	[reply]

Unfortunately the `id` attributes of your form elements do not get sent to your CGI scripts, only the names and values. One of the features (OK, probably the only feature) that I like about PHP is you can name form elements something like `blah[3][2]` and then PHP will automatically create an 2D array with that element's value at `[3][2]`. I wonder if there's a CPAN module for doing similar form parsing in Perl?	[reply] [d/l] [select]
