It seems like you’re trying to create a custom navigation walker class in WordPress to modify the output of your navigation menus. Your code looks mostly correct, but I noticed a couple of potential issues that could be causing errors:

1. In your start_el method, you’re using $args->walker->has_children to check if the current menu item has children. However, $args->walker doesn’t exist. You should instead use $args->has_children, which is a property available in the $args array.

2. You have a typo in the apply_filters function call at the end of your start_el method. You have a space before the function name, which should be removed.

Please make these corrections and see if it resolves your issue. If you’re still facing errors or if there are any other problems, feel free to ask!

The code I provided earlier before your corrections give this error: Fatal error: Declaration of Walker_Nav_Primary::start_lvl(&$output, $depth) must be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = null) in C:\Users\Bethruz\Local Sites\testi\app\public\wp-content\themes\pajucnielu\inc\walker.php on line 18

The error specifically states that the declaration of start_lvl in your Walker_Nav_Primary class must be compatible with the declaration in the Walker_Nav_Menu class. The declaration in Walker_Nav_Menu specifies default values for $depth and $args, but your start_lvl method in Walker_Nav_Primary does not.

By adding default values for $depth and $args, you ensure that your method signature is compatible with the parent class, resolving the fatal error.

Make this change and see if it resolves the issue. If you encounter any further problems or have any questions, feel free to ask!

You solved the problem very well… Thank you very much for saving loads of time.
