J4 Menuitem params

[Harold Smith]

Updating J3 components to J4 and still can't seem to get the menu changes together.  My issue now is the error.. "Cannot access protected property Joomla\CMS\Menu\MenuItem::$params".  Hoping that someone could help with this.  I know it could be simple.

protected function populateState($ordering = null, $direction = null) {
// Initialize variables.
$app = Factory::getApplication('site');

// Load the parameters. Merge Global and Menu Item params into new object
$params = $app->getParams();
$menuParams = new Registry();

if ($menu = $app->getMenu()->getActive()) {
$menuParams->loadString($menu->params);
}

$mergedParams = clone $menuParams;
$mergedParams->merge($params);

$this->setState('params', $mergedParams);

// process show_noauth parameter
if (!$params->get('show_noauth')) {
$this->setState('filter.access', true);
} else {
$this->setState('filter.access', false);
}

Any help with this is Very Much Appreciated.

Appreciate the suggestion, but it didn't  help me out much.

Could someone *please* help me with this small bit of code to get through this error?

[Glenn Arkell]

$app = Factory::getApplication(); 

$menu = $app->getMenu()->getActive() ; 

$itemId = $menu->id; 

$menuparams = $menu->getParams($itemId);

You asked for the code to get the menu item parameters and I have that to you. $menuitem->getParams(), without any additional options. In fact, what you are trying to do there is pretty much unnecessary, because $app->getParams() has already done that for you.

I had some problems getting menu item params in my frontend component as well when migrating from Joomla 3 to 4. I found that swapping from getting the params off the menu object to getting params from the Application object itself seemed to work better. Like:

$app = Factory::getApplication();

$params = $app->getParams();

$param1 = $params->get('params1');

$meta_desc = $params->get('menu-meta_description');

I have updated most of my larger sites from J3 to J4 and the code I use to grab the menu items the current page:
use \Joomla\CMS\Factory;

$menu = Factory::getApplication()->getMenu()->getActive();

if (is_object($menu)){
$menuparam1 = $menu->getParams()->get('custom-menu-param-1');

}

Hannes,
I was not trying to be rude or offend.
What I am trying to do is get the url to send to my script.  It is a demo bar and it wants the urls to load the demos.  My problem is that the code in my model at line "$menuParams->loadString($activeMenu->getParams());" returns null "Call to a member function getParams() on null" so the script will not work to load the demos.

/**
 * Load a url into a page
 */
jQuery.fn.load = function( url, params, callback ) {
var selector, type, response,
self = this,
off = url.indexOf( " " );

As I said before, you don't need all that loadString() stuff at all. Just do $app->getParams()->get(whatever) 

That already contains the current menu items parameters, it is already all merged and in an object. Even in the menu item, it isn't a string but an object since at least joomla 3.0.
