in_array condition problem. Not working as expected

[Spinball]

I have created a new varchar field in the user table to hold a comma separated list of mailinglist ids (a bit like membergroupids). It stores what mailing lists people are subscribed to.

In a template, I want to display a subscribe or unsubscribe link depending upon which mailinglist ids are in their $bbuserinfo['mailinglists'] field.

$bbuserinfo['mailinglists'] contains '1,2'.
But

<if condition="in_array(2,array($bbuserinfo['mailinglists']))">Unsubscribe</if>

does not work.
Any help much appreciated.
Thanks

Solved it.
I added a plugin - fetch_userinfo - $user['mailinglists'] = explode(',',$user['mailinglists']);
turned $user['mailinglists'] into an array so that

<if condition="in_array(2,$bbuserinfo['mailinglists'])">Unsubscribe</if>

Works
