The goal of actions in Wire is to be able to easily listen to page interactions, and call a method on your Wire component (re-rendering the component).

Assuming bellow component is initiated and $nodeId variable is being passed. Here's the basic usage:

class ChangeNodeTitle extends WireComponent {
  public int $nodeId;
  public string $nodeLabel;
  public function mount() {
    $node = Node::load($this->nodeId);
    $this->nodeLabel = $node->label();
  public function changeTitle() {
    $node = Node::load($this->nodeId);
    $node->title->value = substr(str_shuffle("abcdefghijklmnopqrstuvwxyz"), 0, 8);
    $this->nodeLabel = $node->label();
  public function render(): ?View {
    $twig = <<<'TWIG'
        <h2>{{ nodeLabel }}</h2>
        <button wire:click="changeTitle">Change Node Title</button>
    return View::fromString($twig);

Wire offers a handful of directives to make listening to browser events trivial. The common format for all of them is: wire:[dispatched browser event]="[action]".

Here are some common events you may need to listen for:



<button wire:click="doSomething">Do Something</button>
<input wire:keydown.enter="doSomething">
<form wire:submit.prevent="save">

You can listen for any event dispatched by the element you are binding to.

Let's say you have an element that dispatches a browser event called "foo", you could listen for that event like so: <button wire:foo="doSomething">


You can pass extra parameters into a Wire action directly in the expression like so:

<h2>{{ nodeLabel }}</h2>

<button wire:click="changeTitle('a string', '{{ random() }}')">
    Change Node Title

Extra parameters passed to an action, will be passed through to the component's method as standard PHP parameters:

public function changeTitle($aString, $rand) {

  $node = Node::load($this->nodeId);
  $node->title->value = "{$aString} {$rand}";

Like you saw in the keydown example, Wire directives sometimes offer "modifiers" to add extra functionality to an event. Below are the available modifiers that can be used with any event.

stopEquivalent of event.stopPropagation()
preventEquivalent of event.preventDefault()
selfOnly triggers an action if the event was triggered on itself. This prevents outer elements from catching events that were triggered from a child element. (Like often in the case of registering a listener on a modal backdrop)
debounce.150msAdds X milliseconds before handling the action.

To listen for specific keys on keydown events, you can pass the name of the key as a modifier. You can directly use any valid key names exposed via KeyboardEvent.key as modifiers by converting them to kebab-case.

Here is a quick list of some common ones you may need:



<!-- Call action only when event.key is equal to 'ArrowDown'. -->
<input wire:keydown.arrow-down="foo">


"Magic" actions are prefixed with a "$" symbol

There are some "magic" actions that are usually prefixed with a "$" symbol:

$set('property', value)Shortcut to update the value of a property
$toggle('property')Shortcut to toggle boolean properties on or off
$emit('event', ...params)Will emit an event on the global event bus, with the provided params
$eventA special variable that holds the value of the event fired that triggered the action. Example usage: wire:change="setMyProperty($"

You can pass these as the value of an event listener to do special things in Wire.


  • $set() can be used to manually set a component property's value.

    Instead of

    <button wire:click="setMessageToMyValue">My Value</button>

    it can be done as

    <button wire:click="$set('message', 'My Value')">My Value</button>


  • $event() used to get the value of triggered element

    <select wire:change="setMyMessage($">
      <option value="10">10</option>
      <option value="20">20</option>
      <option value="30">30</option>
    public function setMyMessage($value) {
      $this->message = $value;


  • $emit() is the bridge between firing events from JS and handling on back-end and vice-versa
