setCustomData not working

Support & Bugs
1

Hi,

Im doing a plugin that tracks some additional data to the log_visit table. But im having some trouble saving data. My trackingcode looks like this:

As seen i have an array with “tracked_userID” that is set using setCustomData. This seems to work but now the question is how to grap that data on the PHP side. I have the following:

public function getListHooksRegistered()
{
	return array(
		'Tracker.newVisitorInformation' => 'logUserID',
	);
}

…
public function logUserID($notification)
{
$visitorInfo =& $notification->getNotificationObject();
$custom = Piwik_Common::getRequestVar(‘data’);
$visitorInfo[‘tracked_userID’] = $custom[‘tracked_UserID’];
}

But it seems like $custom[‘tracked_UserID’] is empty. If i try to serialize the $custom i get the following:

s:34:"{“tracked_userID”:11751}";

So how am i able to get the “tracked_userID” from the data?

Hi again,

It seems that i have to replace " with real quoetes like " and then do a json_decode.

But why is this nessecery - its gonna be a “Dirty” solution.

So know my code looks like:

public function logUserID($notification)
{
	// retrieve the array of the visitors data from the notification object
	$visitorInfo =& $notification->getNotificationObject();        
	$custom = Piwik_Common::getRequestVar('data');
	
	//This is a diry hack - needs to be fixed!!
	$u = str_replace(""",'"',$custom);
	$s = json_decode($u,true);
	//Hack end!

	       $visitorInfo['tracked_userID'] = $s['tracked_userID'];
}

Sorry, adding documentation, examples, and helper functions for handling custom data is on our ToDo list…

Piwik_Common::getRequestVar sanitizes the input. So instead of str_replace(), use Piwik_Common::unsanitizeInputValue() before calling json_decode().

hi

$custom = Piwik_Common::getRequestVar(‘data’);

what does ‘data’ here refers to?

when i am using it i get the following message…

The parameter ‘data’ isn’t set in the Request, and a default value wasn’t provided

Hi Anita,

‘data’ is just the name of the variable that is used in the server side(php) for the custom data that you set in the Javascript side.

For. eg, in my test.html page I am setting a custom user tracking ID



var customUserTracking = { 'uid' : '11751kiran'};

piwikTracker.setCustomData(customUserTracking);

piwikTracker.trackPageView();
piwikTracker.enableLinkTracking();

In the above example, I am setting the cstom tracking data. Now in order to use the value in my php code I am going to do the following :



$myCustomData = Piwik_Common::getRequestVar('data');
$cleanData = json_decode(Piwik_Common::unsanitizeInputValue($myCustomData),true);
$this->customUserId = $cleanData['uid'];

Looks like you are not setting the data in the JS and trying to use it, that is why you are getting the error.

Hope this helps style_emoticons/<#EMO_DIR#>/smile.gif

But I have set the custom data in my tracking page.[/quote]

Can you share the tracking code where you are setting the value and also the php code so I can see what the problem is style_emoticons/<#EMO_DIR#>/smile.gif

hi

Tracking code: sample/index.php

and in my plugin i have added a hook in getListHooksRegistered()

‘Tracker.newVisitorInformation’ => ‘logProviderInfo’,

and in logProviderInfo()
{
$custom = Piwik_Common::getRequestVar(‘data’);
$s = json_decode(Piwik_Common::unsanitizeInputValue($custom),true);
$visitorInfo[‘user_login_id’] = $s[‘userId’];
}

Is using the method logProviderInfo() in my plugin is a problem?

Looks like you are not using the $notification object in your method

Try this :

public function logProviderInfo($notification)
{
	$visitorInfo =& $notification->getNotificationObject();
	$custom = Piwik_Common::getRequestVar('data');
	$s = json_decode(Piwik_Common::unsanitizeInputValue($custom),true);
	$visitorInfo['user_login_id'] = $s['userId'];
}

Hi,

Whenever some is logged at my website, i add a userid by setCustomData.
Can you tell me, please, how to get the live plugin to output at least a list of these userids?
I couldn’t find out how get this added into the live plugin and i even couldn’t find the customdata at the database :-/ or isn’t it stored by default?

Thanks for help

FYI, I will be working on putting ‘Visitor custom variable’ in Piwik in the next release. Keep an eye on the ticket: Custom Variables support: new JS API and new reports · Issue #1984 · matomo-org/matomo · GitHub or the next release.
