Assigning a different menu dynamically in modfiyMenu event

In PHPRunner, dynamically assigning a menu based on a parameter can be achieved using the modifyMenu event, as you've already discovered. However, there isn’t a built-in assignMenu() function. Instead, you can conditionally modify the items or structure of the menu in the modifyMenu event based on your parameters.

Here’s a general approach to achieve dynamic menu assignment:

1. Use the modifyMenu event: This event allows you to modify the menu items programmatically.

   
   

2. Check for a parameter: You can check for a specific parameter (like a query string, session variable, etc.) and then modify the menu accordingly.

   
   

Here is an example of how you might implement this:

// In the modifyMenu event
if ($menu->name() == "main") {
 // Check for a parameter (e.g., from a GET request)
 $param = $_GET['param'] ?? null; // Replace 'param' with your actual parameter name

 if ($param == 'value1') {
 // Modify the menu for value1
 $menu->addItem("Item 1a", "link1.php", "", false); // Example of adding an item
 $menu->addItem("Item 1b", "link2.php", "", false);
 } elseif ($param == 'value2') {
 // Modify the menu for value2
 $menu->addItem("Item 2a", "link3.php", "", false);
 $menu->addItem("Item 2b", "link4.php", "", false);
 } else {
 // Default menu items
 $menu->addItem("Default Item 1", "default1.php", "", false);
 $menu->addItem("Default Item 2", "default2.php", "", false);
 }
}
Explanation:
The modifyMenu event is triggered when the menu is being built.
We check if the menu being modified is the "main" menu.
We then check for a specific parameter (in this case, using $_GET).
Based on the parameter's value, we add different menu items using the addItem method of the $menu object.

Note:
Make sure your parameter is sanitized and validated properly to prevent security issues.
You can also use session variables or any other method of passing parameters depending on your application's architecture.

This way, you can create a dynamic menu that adjusts based on user input or session state.

What does it mean "assign a menu"? Change a link where it points?

When I say "menu" I mean the ones which are created in the menu editor and shown in the menu list.

For example I want to dynamically swap the entire "main" menu for the "developer" menu if a user is a member of a specific user group.

I know I can swap them on the pages in designer, I was wondering if this is possible in the modifyMenu event.

modifyMenu is designed to work with indifidual menu items.

Add both menus to the page and hide one of them in BeforeDsiplay event.
