The current Joomla implementation looks like

$moduleHelper->getParams()->get('paramName'); // don't remember this one perfectly

Is there a way I can get an array of all parameters? I need to get them in an array ready to filter based on certain specification, something like this:

(array) $moduleHelper->getParams()->get('*');
(array) $app->getTemplate(true)->params->get('*');

Please let me know. Thanks

I would use field groups instead of prefixes to organize fields in the form. This way no additional code is needed:

<fields name="params">
    <fields name="logo">
    <fields name="colors">

To get an object containing all values from logo group:


Specific fields can be accessed using dot separated notation:


I found an answer that explains the nature of the parameters and came up with a solution:

$app = Factory::getApplication();
$params = $app->getTemplate(true)->params;

$array_vars = array();
foreach(json_decode($params, true) as $k => $value) {
    if (strpos($k, 'my_setting_preffix_') !== false){
        $array_vars[$k] = $value;

This is now exactly what I needed and the perfect solution to filter the outcome on the spot.

    json_decode() is unnecessary. $params here is a Joomla\Registry\Registry object which can be iterated.

  • In my code (templates/myTemplate/helper.php) I use $registry = new Registry(); $registry->loadString($db->loadResult()); so json_decode is required. I don't exactly know which methods from which to use (Registry / Database [getDbo]) to not need to use json_decode but I know for sure my method works and is better for my exact need.

    the $params is a Joomla\Registry\Registry object. You can get it n array format using the Joomla\Registry\Registry::toArray() function
