Just simply use    isset   POST  radio    so that whenever i click any of the radio button  the one that is clicked is set to the post     lt form method  post  action  sample php  gt   select sex     lt input type  radio  name  radio  value  male  gt    lt input type  radio  name  radio  value  female  gt     lt input type  submit  value  submit  gt    lt  form gt    lt  php  if  isset   POST  radio            Sex     POST  radio           gt
