setting variables for only the selected items in form

...when a form has a question where the response can be one or more selections either from a series of chech box inputs or a selection list, how would i set into variables only the responses that are checked or selected so that only these values are available for exporting to a mySQL database?
...help with this will be much appreciated.

janaka,

you can check whether the variable is set or not with isset()function..

if (isset($checkbox)){
#set the value for the varibale here..
}

if you mean you have something like ..

option1<input type=radio name=thisfield value=1>
option2<input type=radio name=thisfield value=2>

then form variable $thisfield = 1 or 2 depending on selection, then in a conformation form you would use....

option1<input type=radio name=thisfield value=1 <?php if($thisfield==1){ echo "checked";}?>>

option2<input type=radio name=thisfield value=2 <?php if($thisfield==2){ echo "checked";}?>>

AM I even close to what you meant?
