Step 5. Create a Scheduler

And now, we're going to add a scheduler on the page. The technique used for dhtmlxGrid is the same for all other DHTMLX components, including dhtmlxScheduler.
We will again divide the step into 2 substeps:

If after completing the step, you will run webhost/yii_dhtmlx/web/scheduler, the app will produce the following scheduler that loads data from server and saves them back:

Step 5.1. Configuring the View object

Once again, we will use a standard code initializing the component.

For a deeper learning of dhtmlxScheduler initialization, read:

To configure the View object:

In the "views/scheduler " folder create a new file and name it "index.php "

Open the "index.php " file and add the following code there:

"views/scheduler/index.php" file

<!DOCTYPE html>
<head>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8">
    <script src="../lib/dhtmlxScheduler/codebase/dhtmlxscheduler.js"></script>
    <link rel="stylesheet" href="../lib/dhtmlxScheduler/codebase/dhtmlxscheduler.css">
</head>
 
<body>
    <div id="scheduler_here" class="dhx_cal_container">
        <div class="dhx_cal_navline">
            <div class="dhx_cal_prev_button">&nbsp;</div>
            <div class="dhx_cal_next_button">&nbsp;</div>
            <div class="dhx_cal_today_button"></div>
            <div class="dhx_cal_date"></div>
            <div class="dhx_cal_tab" name="day_tab" style="right:204px;"></div>
            <div class="dhx_cal_tab" name="week_tab" style="right:140px;"></div>
            <div class="dhx_cal_tab" name="month_tab" style="right:76px;"></div>
        </div>
        <div class="dhx_cal_header">
        </div>
        <div class="dhx_cal_data">
        </div>
    </div>
 
<script type="text/javascript" charset="utf-8">    document.body.onload = function() {
        scheduler.init('scheduler_here',new Date(2010,7,1),"month");
        scheduler.setLoadMode("month");
         // refers to the 'data' action that we will create in the next substep
        scheduler.load("./scheduler/data");
        // refers to the 'data' action as well
        var dp = new dataProcessor("./scheduler/data");
        dp.init(scheduler);
    };
</script>
</body>

Step 5.2. Configuring the Controller object

In the controller, we'll use the same technique that was used for Grid. So let's implement the following actions:

One that loads the view.
One that loads and processes data.

To load and process data we will use SchedulerConnector. A common use of SchedulerConnector is:

$connector = new SchedulerConnector(null, "PHPYii");
$connector->configure(new $modelName,$id, $text, $extra);
$connector->render();

The SchedulerConnector constructor takes 2 parameters:

null - null is passed, as a model, not a database is used;
$PHPYii - the module for working with PHP, the hardcoded value.

The configure method configures the SchedulerConnector object without rendering data and takes 4 parameters:

new $modelName - the method creating a model (e.g. new SchedulerEvent());
$id - the name of the id field;
$text - a comma separated list of rendered data fields;
$extra - (optional) a comma separated list of extra fields.

To configure the Controller object:

Create a new file in the "controllers " folder and name it "SchedulerController.php ".

Open the "SchedulerController.php " file and specify the namespace for controllers, include the SchedulerConnector class and the used model - SchedulerEvent:

"controllers/SchedulerController.php" file

<?php
namespace app\controllers;
use Yii;
use yii\web\Controller;
use Dhtmlx\Connector\SchedulerConnector;
use app\models\SchedulerEvent;

Create the root controller class "SchedulerController ":

"controllers/SchedulerController.php" file

<?php
namespace app\controllers;
use Yii;
use yii\web\Controller;
use Dhtmlx\Connector\SchedulerConnector;
use app\models\SchedulerEvent;
 
class SchedulerController extends Controller {           // here you should place all your functions       }

Create an action that will load the view:

"controllers/SchedulerController.php" file

class SchedulerController extends Controller {  
    public function actionIndex() {                 return $this->render("index");          }                                       }

Create an action that will load data to the Scheduler. For building the grid structure we'll use the 'SchedulerEvent' model:

"controllers/SchedulerController.php" file

class SchedulerController extends Controller {
    public function actionIndex() {
        return $this->render("index");
    }
    public function actionData() {                                                                                                     $connector = new SchedulerConnector(null, "PHPYii");                $connector->configure(                                                  new SchedulerEvent(),                                               "event_id", "start_date, end_date, event_name"                  );                                                                  $connector->render();                                           }                                                               }
