Notifications

Setup Laravel Queues for VaahCMS

Follow the following steps:

Set QUEUE_CONNECTION to database in your active env file
Visit Setting > General > Site Settings > Laravel Queues in your backend dashboard and enable it.
Run or setup cron/daemon job for
php artisan queue:work --queue=high,medium,low,default --env=env_filename
If you want to run without cache use following command:
php artisan queue:listen --queue=high,medium,low,default --env=env_filename eg:
php artisan queue:listen --queue=high,medium,low,default --env=develop

If you make any changes in code of your Job class, then you must restart the queue:work command.

Note: When sending notifications, be sure to set the MAIL_FROM_ADDRESS and MAIL_FROM_NAME in your env file. This value will be used as the sender of the email and name of your mail notification messages.

How to create new notification?

There are two way to create notifications:

Using Backend > Settings > Notifications
Use Seeds

1. Create notification from Backend

Here you will be able create new notifications which can be used in your code.

2. Create notification via Seeds

You need to create two json files in your module or theme at following locations:

<theme-or-module-path>/Database/Seeders/json/notifications.json with following content:

[
    {
        "name": "<notification-name>",
        "via_mail": 1,
        "via_sms": 0,
        "via_push": 0,
        "via_backend": 1,
        "via_frontend": 0
    }
]

You can choose the various via by which you want to send the notification.

<theme-or-module-path>/Database/Seeders/json/notification_contents.json

In this file slug is coming from the <notification-name> and each {} object represent the a line for the notification.

[
    {
        "slug": "<notification-name-slug>",
        "via": "mail",
        "sort": 0,
        "key": "subject",
        "value": "Welcome Email"
    },
    {
        "slug": "<notification-name-slug>",
        "via": "mail",
        "sort": 1,
        "key": "from",
        "meta": {
            "name": "#!ENV:MAIL_FROM_NAME!#"
        },
        "value": "#!ENV:MAIL_FROM_ADDRESS!#"
    },
    {
        "slug": "<notification-name-slug>",
        "via": "mail",
        "sort": 2,
        "key": "line",
        "value": "Hello #!USER:NAME!#"
    },
    {
        "slug": "<notification-name-slug>",
        "via": "backend",
        "sort": 0,
        "key": "content",
        "value": "Lorem ipsum #!ENV:APP_NAME!#. Thanks!"
    },
    {
        "slug": "<notification-name-slug>",
        "via": "backend",
        "sort": 1,
        "key": "action",
        "value": "Click",
        "meta": {
            "action":"#!ROUTE:VH.VERIFICATION!#"
        }
    }
]

Name	Description
`slug`	It is the slug of the notification name.
`via`	Represent that this `{}` object belong to how the notification will be sent.
`sort`	Index or sequence of the each object.
`key`	This represent the type of object. mail can have following keys : `greeting`, `line`, `action`, `from`, `subject` backend can have following keys: `content`, `action`
`value`	Value contain the actual content of the `key`. This can have dynamic values like `#!ENV:APP_NAME!#` will be replace by the `APP_NAME`
meta	Any additional information required. Eg: For key `action` it requires `Label` and `Link` like a hyperlink requires a `Label` and `Link`

Now to these notification should be created, whenever the module or theme gets activated. So, now we need to use DatabaseTableSeeder.php , add following methods to seed these notifications:

...
public function run()
{
        $this->seedNotifications();
        $this->seedNotificationContent();
}

public function seedNotifications()
{
    $list = \VaahSeeder::getListFromJson(__DIR__."/json/notifications.json");
    \VaahSeeder::storeSeedsWithUuid('vh_notifications', $list);
}


public function seedNotificationContent()
{
    $list = \VaahSeeder::getListFromJson(__DIR__."notification_contents.json");

    foreach($list as $item)
    {
        $notification = \DB::table( 'vh_notifications' )
            ->where( 'slug', $item['slug'] )
            ->first();

        $exist = \DB::table( 'vh_notification_contents' )
            ->where( 'vh_notification_id', $notification->id )
            ->where('sort',  $item['sort'])
            ->where('via',  $item['via'])
            ->first();

        $item['vh_notification_id'] = $notification->id;

        if(isset($item['meta'])){
            $item['meta'] = json_encode($item['meta']);
        }

        unset($item['slug']);


        if(!$exist)
        {
            DB::table('vh_notification_contents')->insert($item);
        } else{
            DB::table('vh_notification_contents')
                ->where( 'vh_notification_id', $notification->id )
                ->where('sort',  $item['sort'])
                ->where('via',  $item['via'])
                ->update($item);
        }
    }
}
...

How to show notification variables?

If you want to show variables name in notification sidebar.

You need to add getNotificationVariables method in ExtendController of your Theme or Module.


public function getNotificationVariables()
{
    
    $list = [
        [
            'name'=>'#!USER:NAME!#',
            'details'=>'Will be replaced with name.',
        ],
        [
            'name'=>'#!USER:DISPLAY_NAME!#',
            'details'=>'Will be replaced with display name.',
        ],
        [
            'name'=>'#!USER:EMAIL!#',
            'details'=>'Will be replaced with email.',
        ],
        [
            'name'=>'#!USER:PHONE!#',
            'details'=>'Will be replaced with phone.',
        ]
    ];

    $response['status'] = 'success';
    $response['data'] = $list;

    return $response;
}

How to add notification actions?

If you want to add action variables in notification.

You need to add getNotificationActions method in ExtendController of your Theme or Module.


public function getNotificationActions()
{
    
    $list = [
        [
            'name'=>'#!ROUTE:VH.LOGIN!#'
        ],
        [
            'name'=>'#!ROUTE:VH.REGISTER!#'
        ],
        [
            'name'=>'#!ROUTE:VH.RESET!#'
        ],
        [
            'name'=>'#!ROUTE:VH.VERIFICATION!#'
        ]
    ];

    $response['status'] = 'success';
    $response['data'] = $list;

    return $response;
}

How to use variable strings?

There are three types of variable strings.

#!USER:VARIABLE_NAME!# : If the notification contains #!USER:NAME!# string and then the $input array must be: $inputs = "user_id" => X. This will replace the string with value provided in the User Entity.
#!PARAM:VARIABLE_NAME!# : If the notification contains #!PARAM:NAME!# string and then the $input array must be: $inputs = "name" => "John". This will replace the string with value provided in the inputs.
#!ROUTE:VARIABLE_NAME!# : If the notification contains #!ROUTE:VH.LOGIN!# string. This will replace the string with url of that route name provided in the PHP Routes.

$notification = WebReinvent\VaahCms\Entities\Notification::where('slug', "<notification-slug>")->first();

if($notification)
{
    
    $inputs = [
            "user_id" => xxx,
            "notification_id" => xxx,
        ];

    WebReinvent\VaahCms\Entities\Notification::send(
        $notification, $user, $inputs
    );
}

How to add Custom Url?

To add custom url, you need to add param string of custom url: #!PARAM:CUSTOM_URL!#.

You can add this param string in Notification Actions.


public function getNotificationActions()
{
    
    $list = [
        [
            'name'=>'#!PARAM:CUSTOM_URL!#'
        ]
    ];

    $response['status'] = 'success';
    $response['data'] = $list;

    return $response;
}

This is how you can add custom url in method.

$notification = WebReinvent\VaahCms\Entities\Notification::where('slug', "<notification-slug>")->first();

if($notification)
{
    
    $inputs = [
            "user_id" => xxx,
            "notification_id" => xxx,
            "custom_url" => 'https://custom-url',
        ];

    WebReinvent\VaahCms\Entities\Notification::send(
        $notification, $user, $inputs
    );
}

Sending without Laravel Queues

If you want to send the notification without Laravel queues, you can use following code

$notification = WebReinvent\VaahCms\Entities\Notification::where('slug', "<notification-slug>")->first();

if($notification)
{
    
    $inputs = [
            "user_id" => xxx,
            "notification_id" => xxx,
        ];
    
    WebReinvent\VaahCms\Entities\Notification::send(
        $notification, $user, $inputs
    );
}

Sending notifications with Laravel Queues

Note: By default VaahCMS does not use Laravel queues/jobs to send the notification. You must enable it, read Setup Notifications with queues section to know more

To send notification with Laravel Queues, you can use following code:

$notification = WebReinvent\VaahCms\Entities\Notification::where('slug', "<notification-slug>")->first();

if($notification)
{

    $inputs = [
            "user_id" => xxx,
            "notification_id" => xxx,
        ];

    WebReinvent\VaahCms\Entities\Notification::dispatch(
        $notification, $user, $inputs, $priority
    );
}

Name	Description
`$notification`	is the instance of `WebReinvent\VaahCms\Entities\Notification`
`$user`	is the instance of `WebReinvent\VaahCms\Entities\User`
`$inputs`	is the a data array contain values of strings. `user_id` and `notification_id` are required params. Eg. 1. If the notification contains `#!PARAM:NAME!#` string and then the `$input` array must be: `$inputs = "name" => "John"` This will replace the string with value provided in the inputs. 2. If the notification contains `#!USER:NAME!#` string and then the `$input` array must be: `$inputs = "user_id" => X` This will replace the string with value provided in the `User` Entity.
`$priority`	it is the order of execution of the jobs. You can provide following values: `high` ,`medium`, `low`, & `default`

Example

In this example, we register a greeting, a line of text, a call to action, and then another line of text.

        "value": "Thank you for signing up for #!ENV:APP_NAME!# services"
    },
    {

        "via": "mail",
        "sort": 6,
        "key": "line",
        "value": "If your have any queries please contact this #!ENV:MAIL_FROM_ADDRESS!#"
    }
]

Use following code to send a Notification.

$notification = WebReinvent\VaahCms\Entities\Notification::where('slug', "send-welcome-email")->first();

if($notification)
{
    
    $inputs = [
            "user_id" => xxx,
            "notification_id" => xxx,
        ];
    
    WebReinvent\VaahCms\Entities\Notification::send(
        $notification, $user, $inputs
    );
}

The notification channel will then translate the message components into a beautiful, responsive HTML email template with a plain-text counterpart. Here is an example of an email generated by the notification:

Note: When sending notifications, be sure to set the APP_NAME in your env file. This value will be used in the header and footer of your mail notification messages.
