Improving this validate function

Hi guys, I use this function which was provided to me by someone at this site. It works perfectly for validating a users input option against allowed options..

example:

validateInput "1" "1 3 4 5" would return 0 (success)

Code:

function validateInput {
 input=$1
 allowedInput=$2
 
 for allowedOption in ${allowedInput}
 do
  if [ ${input} -eq ${allowedOption} ]
  then
   return 0
  fi
 done
 
 return 1
}

but now we allow users to enter more than 1 number and so this validate needs to be improved

validateInput "16" "1 3 4 5" this should return fail (1) as 6 is not in the allowedInput string.. currently the function return success because "1" is in the allowedInput string.. but I somehow need it to verify all the numbers in the first parameter

any ideas guys?

XmbResetIC(3X11)						  XLIB FUNCTIONS						  XmbResetIC(3X11)

NAME

       XmbResetIC, XwcResetIC, Xutf8ResetIC - reset the state of an input context

SYNTAX

       char * XmbResetIC(ic)
	     XIC ic;

       wchar_t * XwcResetIC(ic)
	     XIC ic;

       char * Xutf8ResetIC(ic)
	     XIC ic;

ARGUMENTS

       ic	 Specifies the input context.

DESCRIPTION

       When XNResetState is set to XIMInitialState, XmbResetIC, XwcResetIC and Xutf8ResetIC reset an input context to its initial state; when
       XNResetState is set to XIMPreserveState, the current input context state is preserved.  In both cases, any input pending on that context is
       deleted.  The input method is required to clear the preedit area, if any, and update the status accordingly.  Calling XmbResetIC, XwcRe-
       setIC or Xutf8ResetIC does not change the focus.

       The return value of XmbResetIC is its current preedit string as a multibyte string.  The return value of XwcResetIC is its current preedit
       string as a wide character string.  The return value of Xutf8ResetIC is its current preedit string as an UTF-8 string.  If there is any
       preedit text drawn or visible to the user, then these procedures must return a non-NULL string.	If there is no visible preedit text, then
       it is input method implementation-dependent whether these procedures return a non-NULL string or NULL.

       The client should free the returned string by calling XFree.

       The function Xutf8ResetIC is an XFree86 extension introduced in XFree86 4.0.2. Its presence is indicated by the macro X_HAVE_UTF8_STRING.
