Fixed my single data issue also. The data I got back from my previous function looked like
a:6:{i:0;s:3:"112";i:1;s:4:" 113";i:2;s:4:" 114";i:3;s:4:" 115";i:4;s:4:" 111";i:5;s:4:" 116";}
Take a note to the spaces, the spaces resulted in incompatible data. To fixed this I changed the line in the function $values = explode(",", $checked); to $values = explode(", ", $checked); and now the data looked like:
a:6:{i:0;s:3:"114";i:1;s:3:"113";i:2;s:3:"116";i:3;s:3:"115";i:4;s:3:"111";i:5;s:3:"112";}
No spaces!
