  • 0

Trying to Catalyse some prototype pages with form fields. My Catalyst controller does not seem to be getting the inputs from the form when it is submitted.

I have tried to reduce the template & controller down as far as I can and I am still getting this problem.

template is simply:

<body>
    <form action="/minimal-testing" method="get">
          <select id="select02">
            <option value="cat1">cat1</option>
            <option value="cat2">cat2</option>
          </select>
          <select id="select06">
            <option value="1">1</option>
            <option value="2">2</option>
          </select>
        <input type="submit" value="submit" title="submit" />
    </form>
    <p> Hello, params says: </p>
    <p>
      [% FOR param IN params ; param.key ; ' = ' ; param.value; END %]
    </p>
</body>

Controller is:

sub minimal_testing :Path('minimal-testing') :Args(0) {
    use Data::Dumper;
    my ( $self, $c ) = @_;
    $c->stash(params=>$c->req->params);
    $c->stash(template => "dynamic/minimal-testing.tt");
    $c->log->debug(Dumper($c->request->params));
}

When I browse to the form, pick from the select options, and submit, my debug log simply says

[debug] $VAR1 = {};

Obviously I am missing something so obvious I am just not seeing it… please enlighten me.

    You’re dead right. I suspect your Catalyst log should be giving you a clue what’s going wrong here. The problem isn’t with Catalyst.

    Basically, it’s malformed HTML – your form inputs each need a name parameter that can be passed back to the server in the POST.

          <select id="select02" name="select02">
        <option value="cat1">cat1</option>
        <option value="cat2">cat2</option>
      </select>

    id is for CSS, name is for FORM processing.

    Try that, and you should get logging like:

    [11:31:28.499 16014:debug] Body Parameters are:

.-------------------+----------------------------------------.
| Parameter         | Value                                  |
+-------------------+----------------------------------------+
| select02          | cat1                                   |
| select06          | 2                                      |
'-------------------+----------------------------------------'

    Hope that helps.
