In Laravel Livewire, you can call a method from one component in another component by dispatch() method in the current component and listening for that event in the target component. So following is the way to achieve this result.

Steps to Call Another Component’s Function in Livewire

1. dispatch an Event in the Current Component

In your current Livewire component, use the dispatch() method to trigger an event. For example:

// CurrentComponent.php
public function callOtherComponentMethod()
{
$this->dispatch('triggerFunction');
}

2. Listen for the Event in the Target Component

In the target Livewire component, listen for the event by defining an event listener in the $listeners property.

// TargetComponent.php
class TargetComponent extends Component
{
protected $listeners = ['triggerFunction' => 'handleTriggeredFunction'];

public function handleTriggeredFunction()
{
// Your logic here
dd('Function in Target Component called! this is another component method');
}

public function render()
{
return view('livewire.target-component');
}
}

3. Use Both Components in the View

Ensure both components are included in the same Blade view or are nested appropriately.

<!-- Example Blade View -->
<livewire:current-component />
<livewire:target-component />

4. Test the Integration

When you call callOtherComponentMethod in CurrentComponent, it emits the triggerFunction event. The TargetComponent listens for this event and executes the handleTriggeredFunction method.

Notes

• Event Parameters: You can pass data along with the emitted event if needed:

$this->dispatch('triggerFunction', $data);

Then, access it in the target component:

public function handleTriggeredFunction($data)
{
// Use the $data parameter
}

• Global Events: If the components are not on the same page, consider using Livewire’s dispatchTo or dispatchUp for targeted or parent communication.

This pattern ensures a clean, decoupled way of communicating between Livewire components.
