Pass xml field inside module's helper class

Question

I have a custom Joomla module. In the helper.php class, I need to pass XML field data.

Here is what I have so far.

class modcatbanerHelper {

    // I need to pass here 
    public $selected_cat = $params->get('title');

    public static function moduleCats($data)
    {
       #or pass here...
    }

}

Answer 1

You can pass in your helper's methods the $params as a parameter.

public static function moduleCats($params)
{
   $title = $params->get('title');
}

Then when you call the method from your mod_module.php:

modcatbanerHelper::moduleCats($params);

Answer 2

This solution helped me to pass xml field data to class in helper.php.

public static function xyz(){
    $module = JModuleHelper::getModule('mod_name');
    $params = new JRegistry();
    $params->loadString($module->params);
    $xyz = $params->get('xyz');
    return $xyz;
}

1. mod_name -> this is the module name. Please replace this.
2. $params->get('xyz') -> this is the parameter found in module xml field. Please replace 'xyz'.
