this meteor method should on server, not client. you're missing callback meteor.call('insertplayerdata') statement. cleaned couple other things (meteor.subscribe should not floating in empty space that).
new code below (untested):
playerlist = new mongo.collection('players'); useraccounts = new mongo.collection('user'); if (meteor.isclient) { template.leaderboard.oncreated(function () { this.subscribe('theplayers'); }); template.leaderboard.helpers({ 'player': function () { var currentuserid = meteor.userid(); return playerlist.find({createdby: currentuserid}, { sort: { score: -1, name: 1 } }) }, 'selectedclass': function () { var playerid = this._id; var selectedplayer = session.get('selectedplayer'); if (playerid == selectedplayer) { return "selected" } }, 'showselectedplayer': function () { var selectedplayer = session.get('selectedplayer'); return playerlist.findone(selectedplayer) } }); template.leaderboard.events({ 'click .player': function () { var playerid = this._id; session.set('selectedplayer', playerid); }, 'click .increment': function () { var selectedplayer = session.get('selectedplayer'); playerlist.update(selectedplayer, {$inc: {score: 5}}); }, 'click .decrement': function () { var selectedplayer = session.get('selectedplayer'); playerlist.update(selectedplayer, {$inc: {score: -5}}); }, 'click .remove': function () { var selectedplayer = session.get('selectedplayer'); playerlist.remove(selectedplayer); } }); template.addplayerform.events({ 'submit form': function (event) { event.preventdefault(); var playernamevar = event.target.playername.value; meteor.call('insertplayerdata', function (error, result) { // handle error/success }); } }); } if (meteor.isserver) { meteor.publish('theplayers', function () { var currentuserid = this.userid; return playerlist.find({createdby: currentuserid}) }); meteor.methods({ 'insertplayerdata': function () { var currentuserid = meteor.userid(); playerlist.insert({ name: "david", score: 0, createdby: currentuserid }); // need error handling return {success: true}; } }); }
