working with checkboxes

you have to check in array if value exist then save in specific database column php in_array function can help you to solve your problem

Code:

if(in_array("sample1",$sample))
   $data['sample1'] = "sample1";

if(in_array("sample2",$sample))
   $data['sample2'] = "sample2";

if(in_array("sample3",$sample))
   $data['sample3'] = "sample3";

or you can do with loop
foreach($sample as $v){
   if("sample1"==$v)
   $data['sample1'] = $v;

if("sample2"==$sample)
   $data['sample2'] = $v;

if("sample3" == $v)
   $data['sample3'] = $v;
}

hope will work for you
