That should be hidden from user interface.

What's the proper way to do that?

Import attached file.

form Hook: Form start

PHP Code:

$hiddenfield1 = $vbulletin->input->clean_gpc('g', 'param', TYPE_UINT);
if (empty($hiddenfield1))
    {
        $errormessage = "Error, this form needs a parameter.";
           eval('print_output("' . fetch_template('STANDARD_ERROR') . '");');
    } 


form Hook: Before Submit

PHP Code:

$hiddenfield1 = $vbulletin->input->clean_gpc('p', 'hiddenfield1', TYPE_UINT);
$formoutput = str_replace('{param}', "$hiddenfield1", $formoutput); 


Then you can use {param} in custom output.
