Question

我正在使用oxwall，我想了解EventManager如何在此平台上运行，以便在特定事件上注册新方法，并使用一个简单示例来触发事件并将事件绑定到流程。

Answer 1

以下是触发事件并将事件绑定到进程的示例。我的格式有点糟糕......

假设您正在创建用于创建用户帐户的插件。

<div flex layout="row" layout-align="center center">
    <div flex-sm="100" flex-gt-sm="90" flex-gt-md="70" flex-gt-lg="50" class="md-whiteframe-z2">
        <md-content class="md-padding">
            <div flex-sm="100" flex-gt-sm="80" layout-sm="column">
                <form name="contactForm" data-ng-submit="sendMail()">
                    <md-input-container>
                        <label>Name:</label>
                        <input ng-model="contactName" required>
                    </md-input-container>
                    <md-input-container flex>
                        <label>Email:</label>
                        <input type="email" ng-model="contactEmail" required>
                    </md-input-container>

                    <md-input-container>
                        <label>Message:</label>
                        <textarea ng-model="contactMsg" columns="1" md-maxlength="150" required></textarea>
                    </md-input-container>

                    ̶<̶b̶u̶t̶t̶o̶n̶ ̶t̶y̶p̶e̶=̶"̶s̶u̶b̶m̶i̶t̶"̶>̶S̶e̶n̶d̶<̶/̶b̶u̶t̶t̶o̶n̶>̶
                    <md-button type="submit" class="md-primary"
                        ng-class="{'md-raised md-hue-1': (contactForm.$dirty && contactForm.$valid) }"
                        aria-label="Send">Send</md-button>
                </form>
            </div>
        </md-content>
    </div>
</div>

将事件绑定到听众

您应该从事件处理程序类或插件init.php文件中执行此部分。

/**
* Method to save user
*/
public function saveUser( $username, $password, $email, $accountType )
{
    $userService = BOL_UserService::getInstance();
    $user = $userService->createUser( $username, $password, $email, $accountType );

    //Set new event parameters
    $event = new OW_Event('plugin_key_custom_event_name', array(
        'userDto' => $user
    ));
    //Trigger an event for after registering user
    OW::getEventManager()->trigger($event );
}

最后，您可以从init.php文件初始化事件处理程序。

/**
*
* Bind Event
*/
class PLUGINKEY_CLASS_EventHandler
{
    public function sendUserWelcome( OW_Event $e )
    {
         $params = $e->getParams();
         $user = $params['userDto'];

         BOL_UserService::getInstance()->sendWellcomeLetter($user);         
    }

    public function init()
    {
        //bind sendUserWelcome() method to 'plugin_key_custom_event_name' event
        OW::getEventManager()->bind('plugin_key_custom_event_name', array($this, 'sendUserWelcome'));
    }
}

oxwall OW_EventManager绑定并触发
