Well, your framework should do this for you :

"integer" specified in your database object class description
"%d" appears in in your generated queries (or you put it in your hand
written queries)
=> if the parameter is not an integer, an exception is thrown, then
catched, then an error page is displayed...

Or, just casting to int should throw an exception...

Forms should be validated, but hidden parameters in links are OK imho to
display an error page if they are incorrect, after all, if the user edits
the get or post parameters, well...
