Retrieve all params from cgi module

[MatthewP]

Hi,

Using the CGI module, how can I retrieve all of the params that have been passed through a form into the program if I don't know what they're called. ie - I know I can do

print "$q->param('my_fieldname')\n";

but if I don't know what the field names are, how can I loop through them as if it were a hash like

foreach $key (keys %ALL_PARAMATERS){
print "$key - $ALL_PARAMATERS{$key}\n";
}

Thanks,
Matt.

You can do this:

my %params = $q->Vars;

Be careful using this if a parameter name can have more than one value (like a checkbox group for example).

Alternatively,

my @param_names = $q->param;
#and then
print "$_ - ",$q->param($_),"\n" for @param_names;

Apologies for the extra post - forgot this method earlier.
