Usage

Once the extension is installed, follow the below steps to send an otp number to the given phone number and save the otp code into database.

Step 1: Run the below query in your database.

    CREATE TABLE IF NOT EXISTS `sendsms` (
      `id` int(11) NOT NULL,
      `phone_number` varchar(15) DEFAULT NULL,
      `otp_number` varchar(6) DEFAULT NULL,
      `status` tinyint(4) NOT NULL DEFAULT '0'
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

    ALTER TABLE `sendsms` ADD PRIMARY KEY (`id`);

    ALTER TABLE `sendsms` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;

Step 2: Generate model Sendsms.php for the table sendsms.

Step 3: Create view file sendotp.php file in views/site folder.

        <div class="site-sendotp">

            <div class="alert alert-success">
                <?=Yii::$app->session->getFlash('successMessage')?>
            </div>

            <div class="alert alert-danger">
                <?=Yii::$app->session->getFlash('failureMessage')?>
            </div>

                <?= $form->field($model, 'phone_number')->textInput(['type'=>'text','class' => 'phone']); ?> 

                <div class="form-group">
                    <?= Html::submitButton('Send OTP', ['class' => 'btn btn-primary']) ?>
                </div>

        </div><!-- site-sendotp -->

Step 4: Create one function like actionSendotp() in site controller.

    <?php
    namespace app\controllers;

    use Yii;
    use yii\filters\AccessControl;
    use yii\web\Controller;
    use yii\web\Response;
    use yii\filters\VerbFilter;
    use app\models\LoginForm;
    use app\models\ContactForm;
    use app\models\Sendsms;

    class SiteController extends Controller
    {

        /**
         * Displays send otp page.
         *
         * @return string
         */
        public function actionSendotp()
        {
            $model = new Sendsms();
            if (Yii::$app->request->post()) {
                $mobile_number = $_POST['Sendsms']['phone_number'];
                $otp_message_body = "Your Verification code is:";
                $send_otp_mode = Yii::$app->smsotp->Send_Otp_Mode;

                //Sending otp number to the given mobile number.
                $send_otp = \twiliosms\sms\Smssendotp::sendMessage($mobile_number,$otp_message_body,$send_otp_mode);
                //echo '<pre>';var_dump($send_otp);
                //exit;
                if ( $send_otp != false && $send_otp !='')
                {
                    $phone_exist = Sendsms::find ()->where ( [ 
                        'phone_number' => $mobile_number
                    ] )->one ();
                    //Checking phone number is already exist in database or not
                    if ($phone_exist)
                    {
                        //updating otp code in database.
                        $update_otp_number = Sendsms::findOne (['phone_number' => $mobile_number]);
                        $update_otp_number->otp_number = $send_otp;
                        if ($update_otp_number->update ( false )) {
                            Yii::$app->session->setFlash('successMessage', "Successfully sent an OTP to your enter phone number");
                        }
                        else{
                             Yii::$app->session->setFlash('failureMessage', "Some Internal server issue occured.");
                        }

                    }else{
                        //Inserting phone number and otp number to database.
                        $model->phone_number = $mobile_number;
                        $model->otp_number = $send_otp;
                        if ($model->save ( false )) {
                            Yii::$app->session->setFlash('successMessage', "Successfully sent an OTP to your enter phone number");
                        }else{
                            Yii::$app->session->setFlash('failureMessage', "Some Internal server issue occured.");
                        }
                    }
                }else{
                    Yii::$app->session->setFlash('failureMessage', "Unable to send OTP, please try again.!");

                }

            }
            return $this->render('sendotp',['model'=>$model] );
        }
    }
