Re^2: How to handle multiple buttons inside CGI form

Thank you for your valuable suggestion. I implemented Radio Button group but one of the value is getting selected by default. Unless user select any choice, how can i deselect radio buttons without turning them on??

Maybe provide an "opt out" button and make that the default so that that is an explicit option. After all, after the user has made a choice they can't go back to the original page state unless you provide an additional button. Perl is the programming world's equivalent of English	[reply]

Maybe this... http://perldoc.perl.org/CGI.html#PRAGMAS -nosticky By default the CGI module implements a state-preserving behavior called "sticky" fields. The way this works is that if you are regenerating a form, the methods that generate the form field values will interrogate param() to see if similarly-named parameters are present in the query string. If they find a like-named parameter, they will use it to set their default values. Sometimes this isn't what you want. The -nosticky pragma prevents this behavior. You can also selectively change the sticky behavior in each element that you generate. [download]	[reply] [d/l]
