If ( there is an alert)

October 18, 2015, 01:43:07 am

How do I know if there is an alert to initiate an action ?

I guess I have got a wrong code here

Code: [Select]

/* Growl Notifications Angular */

if (!empty($txt['notify']))
			echo '
					
<growl-notification class="fading">
    You have active notifications
</growl-notification>';

Or, should I have to replace $txt with $context['notification_set'] ?

Txt only contains strings, so I wouldn't check if it's empty.

What should I check to see whether there is a notification or not ?

Do you mean the mentions? This holds the number of mentions (if you compare it > 0, and true, then there is a mention):

Code: [Select]

$context['user']['mentions']

So, I would need to check 2. If there is like , if there is mention. Then I can display notification.

You check is there is a "mention" (i.e. notification, yeah, same name for two things), a mention includes likes, @ mentions, and some other stuff.

Yes. Is it possible that I can have the code to check both ? I am not good in php.

Some other stuff includes what all ? At the moment, I am concentrating on presence of like and @ mention

PS: I mean, compare if > 0 inclusive

Use what CrimeS suggested. It is for both.

php doubt. Something wrong with this code ?

Code: [Select]

/* Popup alert notification using Growl Notifications */

function growl_based_notification()
{
	global $context;

if (!empty($context['user']['mentions']))

	// Say they have unread alerts.

 
    $html = '<body ng-app="af_notify" ng-controller="growlCtrl">
    
    <growl-notifications></growl-notifications>
    <growl-notification>
      Psst ! You have unread notifications
    </growl-notification>
  </body>';
    return $html;

	
}

Yes and no.

If you mean "is the ElkArte way?" then the answer is: yes there is something wrong.
If you mean "is the code syntactically correct?" Then the answer is: no, nothing wrong.

I asked because I did everything as per this Plunker code but getting no alert despite having an active mention

Another way to say what I wrote it: the snippet of code you posted as is doesn't work in ElkArte, but is valid PHP code.
So, depending on what you are doing it may or may not work.
Guessing from your posts your question is: does that code work in ElkArte?
And then the answer is: no, because "return" is not "echo", and returning the HTML doesn't send it to the template, for that you need "echo", because that's the way ElkArte works.
Then there is the second problem: when $context['user']['mentions'] is 0, $html is not initialized, so ElkArte will throw an error.
