Question

Specifically I’m trying to capture all the POST parameters from a payment gateway as a single string, and then parse them looking for the string ‘ERROR’.

I’m aware that there’s a $c->request->parameters method, but I’m not quite sure how its used and I couldn’t figure it out from the CPAN documentation.

Answer 1

It returns a hash reference with the necessary data

my $hashref = $c->request->parameters;

A form with:

<input type="text" name="username" value="joe" />

Would result in a hashref like:

my $hashref = {
    username => "joe", 
};
