Re^3: Cannot clear cgi param (if it's really what I need to do)

This does not appear to be the case.

BEGIN {
    $ENV{QUERY_STRING} = 'mode=orig';
    $ENV{REQUEST_METHOD} = 'GET';
}
use CGI qw( hidden );

print hidden( 'mode', 'second arg' ), "\n";
print hidden( -name     => 'mode',
              -default  => 'default', ), "\n";
print hidden( -name     => 'mode',
              -default  => 'forced',
              -override => 1 ), "\n";
__END__
<input type="hidden" name="mode" value="orig"  />
<input type="hidden" name="mode" value="orig"  />
<input type="hidden" name="mode" value="forced"  />

Perhaps your code is doing something different from what you think it's doing?

Hi kyle, As I print other hidden params `print hidden( 'day' , $day );` [download] I printed this one `print hidden( 'mode' , 'save' , 1 );` [download] and this don't work. `print hidden( -name => 'mode' , -default => 'save' , -override => 1);` [download] works, but I don't understand why ?

When you don't use the named parameter style, the first argument is the field name and the rest are values for the field. `print hidden( 'mode' , 'save' , 1 );` is short for `print hidden( -name => 'mode' , -default => [ 'save', 1 ]);`	[reply] [d/l] [select]
