Mailing List Archive: Dancer2 form back button

Hi,

About two hours after I asked the question in the previous email, I was able to work out the answer. So just incase someone stumbles on the previous email searching for a similar solution - this is what I did:

Create the buttons in the HTML form and give them all the same name, but set the value field to a suitable string:

<button type="submit" name="ActionButton" value="Edit" >Back</button>

<button type="submit" name="ActionButton" value="Confirm" >Forward</button>

Then in the dancer app.pm file:

post '/currentpage' => sub {
my $ActionValue = body_parameters->get('ActionButton');
if ($ActionValue eq "Edit") {
# any processing then redirect to target page
redirect ('/previouspage');
};
if ($ActionValue eq "Confirm") {
# commands
redirect ('/nextpage');
}
}

I hope that helps someone.

M
