<div class="form-group">
    <label class="btn control-label col-sm-2" for="email">Developer</label>
     <label class="btn btn-info">

        <label class="btn btn-info">
            <input name='pilihan[]' value='16' type="checkbox" autocomplete="off"> User Akses                                           <span class="glyphicon glyphicon-ok"></span>

            <label class="btn btn-info">
                <input name='pilihan[]' value='2' type="checkbox" autocomplete="off"> Konfigurasi User                                          <span class="glyphicon glyphicon-ok"></span>

            <label class="btn btn-info">
                <input name='pilihan[]' value='16' type="checkbox" autocomplete="off"> User Akses                                           <span class="glyphicon glyphicon-ok"></span>
            </label>
</div>
    <div class="form-group">
         <label class="btn control-label col-sm-2" for="email">Outlet</label>
        <label class="btn btn-info">
            <input name='pilihan[]' value='1' type="checkbox" autocomplete="off"> Konfigurasi Menu                                          <span class="glyphicon glyphicon-ok"></span>
        </label>
        <label class="btn btn-info">
             <input name='pilihan[]' value='2' type="checkbox" autocomplete="off"> Konfigurasi User                                         <span class="glyphicon glyphicon-ok"></span>
        </label>
        <label class="btn btn-info">
            <input name='pilihan[]' value='16' type="checkbox" autocomplete="off"> User Akses                                           <span class="glyphicon glyphicon-ok"></span>
        </label>
</div>

So what i want to is save the checkbox value. For now what i can do is

 [pilihan] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 16
        )

i can get the value but the value are free . As you can see from my form above there are developer,admin & Outlet. My question is, how to set the value for developer,admin & Outlet.
