Subscription Tracker Field

In Tikiwiki >= 1.10

This tracker field type is used in a tracker used for an event. The field allows you to set up a counter and to have user subscribing to the event. The administrator can set the maximum number of subscriptions. Each time, a user subscribes the number will decrease. A user can not anymore subscribe if the number is null. The lit of users who have subscribed can be see by the administrator in the field value.

For instance, create a tracker concert with a subscription field.

Now create items in this tracker. For each item, set a maximum number of places. You need to format this value as a number followed by # (ex: 50# means that the concert has 50 places)

Then when you view this tracker item, you will see a box with a Subscribe button and the number of place you want to reserve. You will see an unsubscribe button if you already subscribe and you will see the list of users who already subscribed

When the administrator edit the item field, he will see a value like that:

50#210[3],333,455[2]

That means there is 50 places available, the user (userId=210) has reserved 3 places, the user 333 has reserved 1 place, the user 455 has reserved 2 places
