[dancer-users] Help with a POST

[Richard Reina]

Hi John,

I couple questions about your sample above:

1) in the simple form what should I put for action=?

Here is what I have so far:

<form action="index.tt">
Query:<br>
<input type="text" name="query" value="Mickey">
<br><br>
<input type="submit" value="Submit">
</form>

2) This is what I have for the sub _perform_search
sub _perform_search(

    my $fake_search_results = 'Comcast loves net neutrality";
    return $fake_search_results;

)

Is this okay?
