OneSignal subscribe user through web page using web-push-sdk

Question

Is there a way in one signal web-push-sdk to add user manually and unsubscribe?

I tried this in my subscribeOneSignal() function but nothing happening.

Answer 1

Nice, but I have used it, but it want users to be registered after they login to my site with their emailadress as tag:

<?php
if ($_SESSION['sesId']!='')
{
    $sr = mysqli_query($DBD->conn(),"SELECT * from members where id = '".$_SESSION['sesId']."'");
    if ($rr = mysqli_fetch_array($sr))
    {
        if ($rr['pushtag']==1 && $rr['alreadysendpush'] ==0 ) 
        {
        ?>
    var OneSignal = window.OneSignal || [];
    OneSignal.push(["init", {
      appId: "1c398831-ce91-4a8e-90d8-56cc40b8fa97",
      autoRegister:false,
      showCredit:false,
      disable:false, // betekend geen stanaard bericht als je geaceepteerd hebt notificaties te willen ontvangen
      notifyButton: {
        enable: true /* Set to false to hide */
      },
     safari_web_id: 'web.onesignal.auto.379e9ba9-232a-4433-a939-20e3e6310530'
    }]
    );

                                    OneSignal.push(function() {
                                      /* These examples are all valid */
                                      var isPushSupported = OneSignal.isPushNotificationsSupported();
                                      if (isPushSupported) 
                                      {
                                        // Push notifications are supported


                                            OneSignal.isPushNotificationsEnabled().then(function(isEnabled) 
                                            {
                                                if (isEnabled)
                                                {
                                                  console.log("Push notifications are enabled!"); 
                                                    OneSignal.sendTag("email", "<?=$rr['email']?>", function(tagsSent) 
                                                    {
                                                        // Callback called when tags have finished sending                              
                                                        $.ajax({
                                                            type: "POST",
                                                            url: "<?=HTML_ROOT?>inc/webpush.php",
                                                            data: {
                                                                "email": "<?=$rr['email']?>",

                                                            },
                                                            dataType: "html"
                                                        }).done(function(e) {


                                                        });                                                     
                                                    })
                                                }
                                                else {
                                                  console.log("Push notifications are not enabled yet.");      
                                                }
                                              });


                                      } else {
                                        // Push notifications are not supported
                                      }
                                    });
        <?php           
        } else {

        }
    }
