In the spirit of "gamification"

Thinking back to my history in gaming, I came up with a script that lets you track how many consecutive days a user has logged in.

Basically this means that you can reward users (with a badge, rank?) for logging in every day.

Maybe someone finds it useful.

I use three variables, date,a,b. String example: 2014-07-10,1,5.

Where date is last date the user logged in.

a Is the running total of consecutive logins. If a user skips a day of logging, this resets to zero.

b Is the max number of consecutive days the user has managed to reach so far.

Here's what the script does:

Read string from a custom profile field, field1.

Check last login date (set today if this is the first login (since adding the script, or ever).

If user logged in yesterday as well, increase a by 1.

Check if a is greater than b. If so, increase b by 1.

<!-- Consecutive logins -->
<#if user.registered>
<#assign UserDateLast = restadmin("/users/id/${user.id}/profiles/name/field1").value />
<script type="text/javascript">
var vToday = new Date();var dd = vToday.getDate();var mm = vToday.getMonth()+1;var yyyy = vToday.getFullYear();

if(dd<10){dd='0'+dd} 
if(mm<10){mm='0'+mm} 
vToday = yyyy+'-'+mm+'-'+dd;
var vLastLoginDate = '${UserDateLast}';
var arLastLoginDate = new Array();

if (vLastLoginDate == '') {
	arLastLoginDate[0] = vToday;
	arLastLoginDate[1] = 0;
	arLastLoginDate[2] = 1;
	} else {
	arLastLoginDate = vLastLoginDate.split(",");
	}
var firstDate = new Date(arLastLoginDate[0]);
var secondDate = new Date(vToday);
var diffDays = (secondDate - firstDate) / (24 * 60 * 60 * 1000);


if (diffDays > 1) {
	arLastLoginDate[1] = 0;
}

if (diffDays == 1) {
	arLastLoginDate[1] = Number(arLastLoginDate[1]) + 1;
}

if (Number(arLastLoginDate[1]) > Number(arLastLoginDate[2])) {
	arLastLoginDate[2] = Number(arLastLoginDate[2]) + 1;
}

arLastLoginDate[0] = vToday;

$.post('/restapi/vc/users/id/${user.id}/profiles/name/field1/set', {value: '' + arLastLoginDate});
</script>
