$page->callUnknown() method

If method call resulted in no handler, this hookable method is called.

If you want to override this method with a hook, see the example below.

Example

$wire->addHookBefore('Wire::callUnknown', function(HookEvent $event) {
  // Get information about unknown method that was called
  $methodObject = $event->object;
  $methodName = $event->arguments(0); // string
  $methodArgs = $event->arguments(1); // array
  // The replace option replaces the method and blocks the exception
  $event->replace = true;
  // Now do something with the information you have, for example
  // you might want to populate a value to $event->return if
  // you want the unknown method to return a value.
});

Usage

$mixed = $page->callUnknown(string $method, array $arguments);

Arguments

Name	Type(s)	Description
`method`	string	Requested method name
`arguments`	array	Arguments provided

Return value

null mixed

Return value of method (if applicable)

Exceptions

Method can throw exceptions on error:

WireException

Hooking $page->callUnknown(…)

You can add your own hook events that are executed either before or after the $page->callUnknown(…) method is executed. Examples of both are included below. A good place for hook code such as this is in your /site/ready.php file.

Hooking before

The 'before' hooks are called immediately before each $page->callUnknown(…) method call is executed. This type of hook is especially useful for modifying arguments before they are sent to the method.

$this->addHookBefore('Page::callUnknown', function(HookEvent $event) {
  // Get the object the event occurred on, if needed
  $page = $event->object;

  // Get values of arguments sent to hook (and optionally modify them)
  $method = $event->arguments(0);
  $arguments = $event->arguments(1);

  /* Your code here, perhaps modifying arguments */

  // Populate back arguments (if you have modified them)
  $event->arguments(0, $method);
  $event->arguments(1, $arguments);
});

Hooking after

The 'after' hooks are called immediately after each $page->callUnknown(…) method call is executed. This type of hook is especially useful for modifying the value that was returned by the method call.

$this->addHookAfter('Page::callUnknown', function(HookEvent $event) {
  // Get the object the event occurred on, if needed
  $page = $event->object;

  // An 'after' hook can retrieve and/or modify the return value
  $return = $event->return;

  // Get values of arguments sent to hook (if needed)
  $method = $event->arguments(0);
  $arguments = $event->arguments(1);

  /* Your code here, perhaps modifying the return value */

  // Populate back return value, if you have modified it
  $event->return = $return;
});
