Okay .. you want to know how to process a form which you have no knowledge of .. yes? I am not sure why you would want to do this. If this is what you are trying to do then i don't have an answer for you. if it is just that you don't know about isset() then .. because you have written cow1.htm and cow2.php you do know what checkboxes you have. You can simply if (isset($cow)) {yada yada} Sorry i was not able to help you MK> David Tod Sigafoos wrote: >> Hello Michael, >> >> Monday, December 18, 2000, 13:51:27 PM, you wrote: >> >> MK> <input type="checkbox" name="cow"> >> MK> <input type="checkbox" name="pig"> >> MK> <input type="checkbox" name="dog"> >> >> MK> If cow is 'checked', I get $cow="on", >> MK> but if cow is left unchecked, I get $cow="". >> >> MK> If I knew the names of the variables I was >> MK> getting, I could check to see if they were 'on' or '', >> MK> but I don't know.
