php - Unable to retrieve values from checkbox array -

i have multiple checkboxes(array) codes below:

                            <div class="checkbox">                                 <label><input type="checkbox" name="major[]" value="business" /> business</label>                             </div>                             <div class="checkbox">                                 <label><input type="checkbox" name="major[]" value="public affairs / law" />public affairs / law</label>                             </div>                             <div class="checkbox">                                 <label><input type="checkbox" name="major[]" value="medicine" />medicine</label>                             </div>                             <div class="checkbox">                                 <label><input type="checkbox" name="major[]" value="literature / writing / journalism" />literature / writing / journalism</label>                             </div>                             <div class="checkbox">                                 <label><input type="checkbox" name="major[]" value="technology" />technology</label>                             </div>                             <div class="checkbox">                                 <label><input type="checkbox" name="major[]" value="engineering" />engineering</label>                             </div> 

when form submitted, tried retrieve selected values by:

         print_r($_post['major']); 

it prints:

         array ( [0] => [1] => ) 

it detecting 2 checkboxes ticked somehow unable retrieve values out. doing wrong?

=======================php snippets============================

require 'dbconnect.php';   if($_server["request_method"] == "post"){                  if(isset($_post['major'])){                  $top_majors = implode(',', $_post['top_three_major']);                  echo $top_majors;             }else{                  $top_majors = '-';              } } 

=======================solved============================

ok, solved problem. stupid mistake try clear form fields when browser ready, thus, checkbox values reset before able post.
