Reade form values in custom validation

hi, I'm referring to this custom validation sample:

add_filter('gform_validation', 'custom_validation');
function custom_validation($validation_result){

    // set the form validation to false
    $validation_result["is_valid"] = false;
    $form = $validation_result["form"];

    // specify the first field to be invalid and provide custom validation message
    $form["fields"][0]["failed_validation"] = true;
    $form["fields"][0]["validation_message"] = "This field is invalid!";

    // update the form in the validation result with the form object you modified
    $validation_result["form"] = $form;

    return $validation_result;

}

How do I access the fields actual value to validate it?

$form["fields"][0]["value"] doesn't seem to work?

where in the docs do I find the list of possibilities for this $form["fields"] array?

thanks

In addition, we've written a walk through for using this the gform_validation hook:

Hi Gbotica,

For checkbox values it would be $_POST['input_{field_id}_{choice_index}']. Given your example it would be: $_POST['input_16_1'].

Also, just a handy little tip... you can use php's print_rr function to output all of the values (and their corresponding keys) like so: print_rr($_POST).
