post a combination value instead of many drop-down values - drop-down-menu

Question

i am working on a project where a clerk like professional will make/edit classes time table for educational institute.
so in a day-period cell there are many drop-downs for selecting teacher, classroom/lab, batch of students, subject etc.
and this whole combination of values can be repeated many places in the grid.
so i want to post a single value combining all these 4-5 values through POST data in FORM for that cell location.
what approach should i use?
EDIT:
Oh! Yes, i am actually using PHP and angularjs and this is sample code in html
<table border="1" width="90%" height="90%" style="margin:10px">
<thead>
<tr>
<td>
Day
</td>
<td ng-repeat="hour in chours">
{{hour.name}}
<br>
{{hour.stime}}--{{hour.etime}}
<br>
<input type="checkbox" ng-model="hour.noclass" /> No class {{hour.noclass}}
</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="day in weekdays">
<td>
{{day.name}}
</td>
<td ng-repeat="hour in day.hours">
<div ng-show="hour.noclass=='false'" name="cell[{{day.name}}][{{hour.name}}][]">
<select name="cars">
<option ng-model="dd" ng-repeat="sub in subjects">{{sub.name}}</option>
</select>
{{dd}}
</div>
</td>
</tr>
</tbody>
<tfoot></tfoot>
</table>
and this is in js file
var App = angular.module('tteditApp',[]);
App.controller('editCtrl', function($scope){
$scope.chours=[
{'name':'1','stime':'800','etime':'855','noclass':'true'},
{'name':'2','stime':'855','etime':'950','noclass':'true'},
{'name':'3','stime':'800','etime':'855','noclass':'false'},
{'name':'4','stime':'800','etime':'855','noclass':'false'},
{'name':'5','stime':'800','etime':'855','noclass':'false'},
{'name':'6','stime':'800','etime':'855','noclass':'false'},
{'name':'7','stime':'800','etime':'855','noclass':'false'},
{'name':'8','stime':'800','etime':'855','noclass':'false'},
{'name':'9','stime':'800','etime':'855','noclass':'false'},
{'name':'10','stime':'800','etime':'855','noclass':'false'}];
$scope.subjects=[{'name':'CLOUD'},{'name':'CC'},{'name':'ISS'},{'name':'DCT'},{'name':'DMW'},{'name':'VLSI'},{'name':'SEMINAR'},{'name':'PROJECT'},{'name':'WEB DEV'}];
$scope.weekdays=[{'name':'Monday','hours':$scope.chours},{'name':'Tuesday','hours':$scope.chours},
{'name':'Wednesday','hours':$scope.chours},{'name':'Thursday','hours':$scope.chours},{'name':'Friday','hours':$scope.chours}
,{'name':'Saturday','hours':$scope.chours}];
});
